When mechanical switching was introduced to replace operators, the equipment was sensitive to contact bounce when phone sets went off hook. This caused the step by step switches to advance one notch. To accommodate the contact bounce, the first '1' received was discarded. This eliminated the use of the '1' in an exchange name. The alpha characters were then assigned to the numerals '2' through '9' and yes, the early dials had a 'Z' on '0'. Since this mechanical equipment was a replacement for the more personable operator systems, many subscribers resented dealing with a machine just as many today resent dealing with answering machines. The need for a quick access to a living person was recognized and so a special code was given to 'Operator". Even though '1' could not be used as an exchange mnuemonic, it was used for special telephone company services such as information and repair service. ( At this time in history, the motto of Ma Bell was "Service is our only product.", since then the MBA's and LLD's have replaced that concept with "How can we get maximum profits." ). This was accomplished by doubling the '1' into '113' and '114'. Other '11N' codes were used for test purposes such as 'ring back', 'dial speed' and 'line quality'. For some reason, these codes were reversed into the '611' etc. that are used as a standard today. I think that these were a feature of the infamous 'frame' switch. Since many of these switches were installed in populace areas, the step by step's had to be modified when a national standard became desirable. When Direct Distance Dialing was conceived, this lack of the '1' and '0' in local exchanges was noted. Since they still had local importance as first digits, they were placed in the second position. This was used to 'flag' the equipment that the number being dialed was an area code and that the call should be connected to the long lines equipment. As a side note, the area codes easiest to dial on a rotary dial were assigned according to the amount of incoming traffic at the time. Thus '212' was given to New York City and '213' to Los Angeles etc. It was also at this same time that Ma Bell went from the named exchanges to full numeric in order to use some combinations which were impossible with mnuemonics. I hope that this piece of historical trivia will enlighten some readers. Vernon C.

Just what is the "lowest list price"? Rates from different service providers differ not only on first-minute or first-3-minute charges, but also on subsequent-minute charges. Which is cheaper often depends on how long you talk...how is the computer supposed to know if you're making a 1- or 3-minute call, or a 5-10 minute call? Does the system have to keep a customer-history log on you and use AI techniques to figure out how long you're *probably* going to talk? And how will it account for multiple subscribers using the same line? Not to mention knowing if you prefer a certain provider for calls to particular locations, due to line quality considerations...

This is sheer obfuscation. Don't expect this to change unless we rewrite the Constitution to eliminate States. As long as we have a Federal system, interstate rates will be under Federal control, and local rates under State control.

Equity requires that 20 ordinary phone lines should not cost simply 20 times the cost of one phone line, since there are economies of scale. After all, I could use a digital loop carrier to run 20 lines to one location. I also only have to send one bill. These savings should translate into lower rates for 20 lines to one location--Centrex--than 20 individual lines to different locations. > (4) Least call call routing.

Centrex users can in fact buy such a service from the local telephone company, but it is costly. The reasons it costs so much is an element of the divestiture which could be changed without changing the Constitution. Bascially, the MFJ forbids a BOC from having anything to do with "selecting" which long distance company carries your traffic. This strict language was put in in reaction to the pre-divestiture behavior of the BOCs which favored AT&T. The way Centrex customers get around the rule is that the BOC establishes a capability for routing calls, but the Centrex customer is responsible for downloading to the CO the routing tables to be used (i.e. which area-code/exchange numbers should be routed via which carrier). Thus, it is argued, it is the customer, not the BOC who is "selecting" the carrier. Unless you can afford to update and manage these routing tables, you can't afford the least cost routing service, and the BOCs are currently prohibited from doing it for you.

In many respects, deragulation, as practiced in the United States, is a little like throwing out the baby with the bath water. What do I mean? Well, by way of example, I went to SIGGraph last year in Atlanta. This little ET sure had a difficult time calling home! When I tried to dial the call myself, I could not get through (I can no longer remember the exact problem :-( ). So, naively I tried to ask the operator to place the call, after explaining the problem. Seemingly, every time I dialed 0 I got an operator from a different system. Certainly, the responses weren't consistent with a single training program. So, I had to field questions of "what LD service do you want to use?". Dammit, I just want to call home! I eventually succeeded, but I vowed to fight any similar efforts to deregulate Canada's telecommunications industry. Digression: airline deregulation is similarly bad. The benefits are lost in the enormously higher risks as airlines ignore safety (take Eastern Airlines, for example, (please?)). If Canada goes for deregulation, I hope we can achieve a balance between the important factors of usability, convenience, and safety versus the other benefits of deregulation (increased competition, purportedly bring costs to the consumer down). Well, enough said. I hope this fuels the fires, without starting any flame wars.

I remember that at the time that AT&T decided to go with the flow there was a serious question about how much long distance ratres would rise and to what extent universal service would continue to exist since the major customers of LS serve were bypassing at an alarming rate. Thus either we had to move towards the current situation or towards the European model of strinctly forbidding any transmission of information which bypasses the official carrier. In the US this would probably have ended up as a Data Tax on communications capacity. I agree that the local companies should have been treated more firmly and required to improve the system working towards the best available technology.

I agree. I get tired of hearing all the AT&T employees on here who buy the company line about their LD being best. I must say that AT&T's digital connections are superb, even surpassing Sprint's, but they are still all too rare. Recently, when I mentioned to an AT&T rep that I used Sprint, his (obviously canned) response was, "Oh, you like fiber optics? Well, AT&T _invented_ fiber optics." I explained to him that I didn't care who invented it; I just want a clear, loud connection when making calls. Let me say that I appreciate the level of service offered by AT&T, and this is especially obvious after having to deal with Sprint. We also use nothing but AT&T computers here (even though AT&T doesn't make them) because of the great service we get from them. And I would be willing to pay a little more for that service. But AT&T LD is not a little more, and they are decidedly inflexible. I always give them a chance when we are re-evaluating LD service, but because they won't let us combine all our locations for a quantity discount (unless we pay a $2500 monthly fee), they are just way too expensive.

If anyone out there ever has had to use NTS (National Telephone Sys., I think) from a COCOT or hotel or for whatever reason and not been able to get a hold of an AT&T operator, there is a trick you can use, although it may not get you a human AT&T operator. From what I understand, all the LD services (AT&T, MCI, Sprint, etc.) and the AOS firms (ITI, NTS, etc.) are charged for accessing the national calling card database (or whatever the system is called) for verifying a calling card. AT&T is supposedly charged $.07 per call, while the AOS firms are charged something like $.40. This is one of the reasons they cite when they defend their higher rates. In any event, many AOS firms don't really check. ITI (International Telecharge) just checks to make sure the card "looks" valid, ie, a real area code, a real exchange in that area code, and a somewhat valid looking calling card PIN number. During busy hours, they are less careful, as I've entered "wrong" PINs and totally wrong numbers at times and it went through fine. Late at night they check more often, and frequently a false PIN that was accepted at 5PM won't work at 11PM the same evening. NTS, on the other hand, seems to be doing something that I, as an AT&T customer, find *very* disturbing. When I use an NTS payphone, I get the NTS "boing" tone to enter my calling card number. After that, NTS says "please wait for card verification". I hear lots of clicks, and after a minute or so, the call goes through, and you hear "Thank you for using NTS". Sounds normal, right? Fine, but enter an INVALID card number, and see what happens then. You go through the normal routine, ie, tone, then a long period of clicks, but rather than say "Invalid number" or whatever, you hear the *AT&T* system come on and say "Please dial your card number again now, the card number you have dialed in not valid". THEN, if you enter a VALID AT&T/Bell card number, you hear "Thank you for using AT&T"!!! It seems what NTS is doing is using AT&T's calling card system to verify calls for them, and then place the call over NTS after they use AT&T to check! Here's what I think happens: 1. Caller calls NTS with a 0+ call. 2. NTS gets the card number info, and then dials (via AT&T) 0+ac-dest number, waits for the AT&T tone, and then dials your card number. If the NTS system hears "Thank you for using AT&T" (or knows that a valid AT&T card gets a response faster than an invalid one), it hangs up, and places the call over NTS lines, so you don't get billed via AT&T. 3. If the call is invalid, it frequently leaves the line open so you can hear the invalid message from AT&T. You can THEN enter your real number, and get billed via AT&T (but the location may be different from where the payphone is physically located, as the NTS center is probably not near the payphone, and the call is sent out from the NTS center, not the payphone.) I've tried this a few times, and it always happens this way. I've also entered an invalid number, and then gotten the AT&T "please re-enter" recording, dialed in my AT&T card, and was later billed by AT&T with no mention of NTS. The call also came from Maryland, if I recall correctly, although I was in Springfield, Mass, calling to Boston. Has anyone had similar experiences with NTS? Is my supposition correct? Is NTS using AT&T to verify card calls, thus saving at least $.40 per call and running up AT&T's bill instead? Is this legal? Does AT&T know about this? Well, thought I'd pass the results of my experiences with NTS along and see what anyone can come up with... -Doug dreuben%eagle.weslyn@wesleyan.bitnet dreuben@eagle.wesleyan.edu (and just plain old "dreuben" to the few locals left...! :-) ) (about 5 now, right?) ------------------------------ From: Mike Morris Subject: Another Phreak/Harassment Case History Date: 18 Jun 89 07:25:30 GMT Reply-To: Mike Morris In article telecom@eecs.nwu.edu (TELECOM Moderator) writes: >X-TELECOM-Digest: volume 9, issue 198, message 1 of 6 >Persons attempting to call the Probation Office in Delray Beach, FL on Monday >were connected to a phone sex hotline operated by a woman named 'Tina' >instead. >Southern Bell Telephone Company officials have acknowledged that a >hackerphreak invaded a central office over the weekend, using a computer and >modem, and reprogrammed their computer in such a way that calls intended for >the Probation Office were instead routed to a New York-based phone sex line. > ...edited to reduce bandwidth... >"People are calling the Department of Corrections and getting some kind >of sex palace," said Thomas Slingluff, a spokesman for the Palm Beach County >Probation Department. >Southern Bell officials said it was the first time their switching equipment >had been maliciously reprogrammed by an outside computer intruder.

The system also has a telephone interconnect. A unlicensed person acquired a amateur handheld and proceeded to harass us. It took several weeks to identify the person and get the local FCC office interested in prosecuting him (the local PD wasn't interested), and during that time he made our life miserable. The person knew the local phone system _very_ well, and pulled such nasties as: disconnect the line, busy out the line, disconnect it for outgoing calls, disconnect it for incoming calls, call forward incoming calls to the local "dial a KKK recording" (this changed to the NAACP, dirty-joke-of-the-day, bedtime story, etc recordings almost daily), and other dirty tricks. But the crowning glory, and the one that people still talk about, was when he converted our autopatch line to a pay phone line! (Ever try to drop two dimes into your Motorola walkie-talkie?) Needless to say the local telco security people were interested in the situation once we got their attention. (BTW the person is in jail, and will be for several years.

I start a call in Cell Site "A", on channel 555. I then drive to site "B", and am switched to a new channel. My question is: How does the new site, "B", know that I only have a 666 channel phone? Or does it know? Will it know not to connect me to channel 821, or will it try to connect me to 821, see that I don't responsd, and then try a lower, below-666 channel? Also, do cell systems leave space in the below-666 range for phones that don't have 832 channel capabilities? IE, if a most of the below-666 channels are used, will it reserve some for callers that can't go above 666 so that if they come into the area they won't be cut off?

And while it was true at the time of divestiture that the BOCs were in bed with ATT, this has changed. I think a regulated choice could work today. Somebody else said that the different carriers have such different tariff structures that it would depend on the call length which was cheapest (and thus could not be determined at call setup time). Since this is wish list time, I'd propose that regulators stipulate the structure of the tariff: Call setup charge + per minute charge, and that the slection be based on the cost of a 3-minute call. (If your calls are of a different pattern, or if you can negotiate a better discount, you can still select your own carrier). I maintain that this would spark an intense competition between carriers.

Covert" Date: 19 Jun 89 10:38 Subject: Description of the German cellular system Prospectus of the Radio Telephone Service of the German Bundespost (C-Netz) [Translated by John Covert] 1 General The German Bundespost is introducing a new generation of Radio Telephone Service -- the Radio Telephone Network C. Anyone can subscribe to this service for the transmission of information (voice, data, documents, etc.) Radio Telephones are, in accordance with the instructions of the Telecommunica- tions Regulations, subscriber instruments of the public telephone network. No right exists for the authorization or taking possession of a Radio Telephone. 1.1 Radio Telephone Connection A Radio Telephone Connection consists of a privately owned Radio Telephone, which, as a vehicular telephone or, in the future, also as a portable radio telephone, is connected without wires to the public telecommunications network. A radio telephone can make direct dialled connections to stations of the public domestic and international telephone network -- including other radio telephones -- and can also be reached from these stations. A Radio Telephone may only be installed in Land or Water vehicles (motor vehicles, rail vehicles, domestic ships). Thus usage in aircraft is excluded. The usage authorization is valid only in the service area of the German Bundes- post. Call Connections from and to Radio Telephones are established via Fixed Radio Stations of the German Bundespost. Each Fixed Radio Station serves a specific area, the Radio Cell. The range of a Fixed Radio Station depends on the local geographic conditions. In order to be able to conduct calls, the Radio Telephone must be located in the service area of a Fixed Radio Station. In valleys, behind tall buildings, in underpasses, etc., "Radio Shadows" can exist, which may occasionally cause interruption of calls. Gaps in service are unavoidable because of radio transmission technical reasons. The usage of a future portable radio telephone inside buildings will be more or less impaired depending on construction methods and location; this applies especially in basements and underground garages. 1.2 Authorization Card Each subscriber to the Radio Telephone Service receives an Authorization Card issued in his name and equipped with his telephone number. This Authorization Card, the size of a check-cashing card [same size as a credit card], enables the operation of the Radio Telephone. The Radio Telephone Number is not bound to the Radio Telephone, but to the Authorization Card. The resulting call charges are accumulated and billed based on this telephone number. Thus the Authorization Card is a credit card and is to be carefully preserved from loss. One can use one's own Authorization Card to make calls from someone else's Radio Telephone, charged to one's own account, for example, from a taxi. [In actual practice, taxis and rental car companies (at least AVIS) forbid the use of your own card, in order to collect triple the normal rates for usage.] One can become a subscriber even without owning a Radio Telephone. Such customers also receive an Authorization Card and can use this card to use other authorized and technically accepted Radio Telephones. The call charges, in this case, will be charged to the person possessing such a card. Shared use or exclusive use by others is permitted. This will be interesting for example for car rental agencies who can offer cars with radio telephones. In this case the car rental agency must also be a subscriber. The German Bundespost also issues Authorization Cards for measurement purposes to Radio Telephone Dealers, if these dealers are C-Netz subscribers. No calls can be made with Authorization Cards for measurement purposes. The service order form for your radio telephone is to be kept near your OWN telephone and must be presented in the case of any investigation. Should you lose your Authorization Card, please, in your own interests, report this immediately to the Telecommunications Office in Mannheim, telephone number (06 21) 10 51 00, giving your name, your address, the Authorization Card number and the Radio Telephone number. The Telecommunications Office in Mannheim will arrange to block your radio telephone connection as fast as possible, if you so request. There is a charge for this request. Then, please confirm your tele- phonic loss report in writing. The Telecommunications Office in Mannheim will then immediately send you a new Authorization card. Your radio telephone number will not be changed by this process. With the new card you can use your radio telephone without further ado. The use of your old card remains blocked. This procedure offers a great level of protection against unauthorized placing of telephone calls at your cost. 1.3 Nationwide Reachability Every operational powered-up radio telephone in the service area of the German Bundespost can be automatically reached by dialling the nationally uniform access code (01 61) [+49 161] and the succeeding individual seven digit radio telephone number without regard to the current location. You can observe the operational status of the radio telephone by the illumina- tion of a green light. The radio telephone should always be turned on, so that your are always reachable. 1.4 Protection against interception of calls The radio telephone system prevents the allocation of radio channels which are already occupied by other calls. Listening to calls with your own radio tele- phone is therefore not possible. These measures, however, offer no technical protection against the illegal interception of radio telephone traffic with special radio receivers, which is, in accordance with section 15 of the law concerning communications devices (even in the case of carelessness) and section 201 of the StGB, subject to legal penalties. As an additional security measure, your radio telephone disguises [does not encrypt] the radio transmissions. This offers protection against undesired interception of the calls. 1.5 Cell switching In the C-Netz, telephone calls are automatically transferred to the next fixed radio station when you leave the service area of the current fixed radio station as long as this is permitted by radio coverage. In general, a call can be conducted over a long distance without interruption. 1.6 Conference calls If the radio telephone is going to be used for a conference call, it is recom- mended to stop driving and to make the call from the stationary vehicle in order to avoid "Radio Shadows". Conference calls are to be booked through the telephone office, telephone number 010. 1.7 Flexible call length In the case of a heavy increase of traffic in a radio cell, the traffic capacity of the radio channels must be managed through a waiting queue technology in order to allow as many subscribers as possible the opportunity to at least make a short call. The otherwise unlimited call length becomes flexible, i.e. limited dependent on traffic conditions. The speaking subscriber receives a short notification tone and should then quickly terminate his call. 2 Overview Map and Service Gaps The locations of the fixed radio stations currently in service are indicated on the overview map. The covered areas are indicated by shading. Areas not covered are white. In the areas indicated as covered there will always exist, as a result of the physical transmission requirements more or less large and numerous "Radio Shadows" or Service Gaps (e.g. in valleys, behind free-standing buildings, in underpasses), which can interfere with or completely prevent the establishment or continuation of a call. As a rule it is not technically nor economically possible or reasonable to eliminate these service gaps. 3 How does one become a subscriber? 3.1 Purchase If you want to become the possesor of a radio telephone connection, you can purchase your radio telephone yourself. You obtain information about purchase, installation, use, and service of the apparatus from specialized dealers and service providers. You may only use radio telephones and accessories which have been authorized by the Bundespost; these carry a DPB-authorization number. 3.2 Service Order You request permission to operate a radio telephone or subscription to the radio telephone service without a telephone at the service order location for telecommunications apparatus responsible for your place of residence. This office issues your radio telephone number and arranges an entry in the telephone book. You will be issued a telephone number even if you do not have a radio telephone; this is necessary in order to produce your telephone bill. Forms for the service order request can be obtained at the service order location for telecommunications apparatus. You may place your radio telephone into service only AFTER the service order has been processed by the German Bundespost. The applicant must provide evidence of a place of residence or work within the service area of the German Bundespost. 3.3 Acceptance Prior to placing the radio telephone into service you must present it to a service location of the Post Office established for the purpose of the technical acceptance of radio telephones. There is no guarantee for the freedom from deficiencies of the device or its installation associated with this acceptance. If there are no objections raised at this acceptance, an authorization card for the use of the radio telephone will be issued. With this authorization card it is also possible to operate every other radio telephone -- as long as its owner permits it. The resulting call charges will accumulate on the telephone bill of the possessor of the authorization card. 3.4 Termination When you terminate your radio telephone connection, the Post Office will notify you how you are to take the radio telephone out of service. Please return the authorization card to the service order location for telephone apparatus responsible for your place of residence. 3.5 Transfer At the present time, transfer of a radio telephone is only possible via termination of the previous authorization and reestablishment of service by a request from the new customer. A transfer regulation without termination and reapplication is being prepared. 3.6 Telephone book Subscribers with radio telephones are listed in the telephone book. In the main entry at most three successive print lines are without charge. Only the text necessary for looking up a subscriber will be entered. Auxilliary listings are possible. Subscribers without radio telephones will not be listed in the telephone book. 4 Charges The following charges for a radio telephone will be billed by the telecommuni- cations billing center in Mannheim: 4.1 Acceptance (including repeated acceptance)...... 100,- DM 4.2 Monthly base charge............................. 120,- DM 4.3 Monthly base charge for an authorization card for measurement purposes.................... 10,- DM 4.4 Blocking........................................ 15,- DM 4.5 Call charges for directly dialled calls 4.5.1 Domestic calls One message unit (0,23 DM) each................... 8 seconds Off peak time as well as Saturdays, Sundays, and nationwide holidays, one message unit each....... 20 seconds These charges are valid for calls from radio telephones and from wire telephones to radio telephones. [The CALLER always pays the charge; there is no charge to the radio telephone subscriber to receive a call.] 4.5.2 International calls Depending on the country, calls originating from radio telephones will incur the charges associated with one of the three international rate zones [for normal telephones] (without reductions for zones near borders) and then a surcharge of one message unit each 16 seconds (off-peak 40 seconds). 4.6 Call charges for operator assisted calls 4.6.1 Domestic calls Rates provided by domestic information. 4.6.2 International calls Rates provided by international information. 4.7 Unauthorized use In the case of unauthorized use of the radio telephone (for example before the acceptance test or after the termination of the subscriber relationship) a charge of 1.5 times the normal base charge for the period of the unlawful use (but at least the charge for two months) will be levied. 5 Instructions for use 5.1 Directly dialled calls from the radio telephone You reach fixed telephone connections from the radio telephone in the usual manner; you dial only the city code and telephone number of the telephone connection you wish to reach. Observe the operating instructions for your radio telephone. If a channel is free, the connection to the desired sub- scriber will be established. If there is no free channel at the moment, the system will indicate to you either that no further calls can be processed at this time or that your call has been placed into a wait queue. As soon as your call has neared the end of the queue, the call processing in the public telephone network is begun. If no channel is free after successful call establishment, the subscriber you have called will receive the announcement "Funkgespraech, bitte warten". [Real great if you're calling someone who doesn't understand German! This recording can also occur on incoming calls.] Immediately after a channel becomes free your connection will be established. After a successful call, your radio telephone number, together with the accumu- lated message units and necessary call data will be stored only for billing. You can also conduct a call from one C Radio Telephone to another C Radio Telephone by dialling 0161 and the radio telephone number. To call B Radio Telephones [older system] (B or B2 devices) you must dial the code for the base station where the telephone is presumed to be located. This means that the approximate location must be known. The codes for B base stations can be obtained from the telephone information service. 5.1.1 Telegrams You may send telegrams from your radio telephone by dialling the national standard number 1131 and by giving your radio telephone number. 5.1.2 Emergency calls If you want to report an emergency, please dial the national standard numbers 110 (police) or 112 (fire department). Since the reporting centers are responsible for a large area, it is absolutely essential that you provide an exact location. 5.2 Operator assisted calls from the radio telephone If the desired telephone connection cannot be established by direct dialled service (e.g. connections to certain locations in the German Democratic Republic or foreign countries), book the call with the telephone office. Use 010 for domestic calls and 0010 for international calls. As soon as the telephone office answers, give your own radio telephone number. (Example "HIER FUNKTELEFON C-Anschluss 2012345"). When booking the call, please give the name of the desired locality and the telephone number of the desired telephone connection. If the call cannot be established immediately, the telephone office will call you back. For each manually established call you will receive a call charge form enclosed with your telephone bill. 5.3 Directly dialled calls to radio telephones. From within the service area of the German Bundespost, a radio telephone is dialled by dialling the access code 0161 and the seven digit individual radio telephone number. (Example: "01 61 2012345"). If the desired radio telephone connection is busy, this will be indicated by the normal busy tone. If the radio telephone is not turned on or is not within the service area of a fixed radio station, the caller will receive the announcement "Dieser Anschluss ist voruebergehend nicht erreichbar". For calls from international locations special procedures apply; further information can be obtained from the international information service. [In fact, you just dial +49 161 and the number, as expected.] 6 Taking a radio telephone along when leaving the service area of the German Bundespost. 6.1 General As a rule, the radio telephone may not be turned on outside the service area of the German Bundespost (if it is permitted to remain in the vehicle upon crossing the border). Be absolutely sure to observe this, as you can otherwise disturb foreign radio services. If you fail to observe this you should expect punishment. Special agreements exist for the following countries: 6.2 Switzerland During a temporary visit the radio telephone may remain in the car. It may, however, under no circumstances be turned on, even near the border. 6.3 France When crossing the border into France, the radio telephone may remain in the car if you prepare the following label and attach it to the telephone: "L'usage de cet appareil est interdit sur le territoire francais sous peine des penalites prevues par l'article L.39 du Code des Postes et Telecommunications" (The use of this device on French territory is prohibited under pain of penalties in accordance with article L.39 of the postal and telecommunications law.) 6.4 Italy The radio telephone can remain in the car, but must be made unusable by the border authorities, who will seal it. 6.5 Rumania When crossing the border the radio will be sealed and the traveller will be notified that he cannot use the radio in Rumania and that the seal must be undamaged upon exit from the country. 6.6 Sweden The radio telephone, if it is permanently installed, may remain in the vehicle. No special permission is required. 6.7 Yugoslavia At least one month before travel an application for permission to import a radio telephone must be submitted to the foreign representative for Yugoslavia. 6.8 Spain When crossing the border, a time-limited import-authorization will be provided by the customs authorities. 6.9 Denmark When crossing the border into Denmark the radio telephone may remain installed under the precondition that an authorization has been obtained from the Danish telecommunications authorities and that the telephone will not be used while in Denmark. 6.10 Transit through the German Democratic Republic When travelling from the Federal Republic to West Berlin and vice versa it is necessary to obtain an authorization from the border authorities of the German Democratic Republic. There is a charge for this authorization, which does not authorize use of the telephone. ============================================================================= [Moderator's Note: My very special thanks to John Covert for translating this material and sending it along to the Digest.

Perhaps Lars considers our system of mixed state-federal sovereignty to be a fiction, but it is deeply enshrined in our Constitution and most Americans wouldn't have it any other way. The Supreme Court issued a ruling which led to the interstate subscriber line charge. I think it was "Smith Vs. Illinois" (not the only case by that name) ca. 1930, and it held that since local telephone lines were part of a network that carried interstate calls, local phone lines are subject to federal regulation under the interstate commerce clause of the Constitution. Congress gave the FCC that authority. Local phone line costs are proportionately divided between state and interstate (FCC) jurisdiction, based on the overall ratio of interstate usage (Subscriber Line Usage, SLU, is the formal term). SLU is computed for a jurisdiction (state). Now before the FCC changed the rules at around the same time as divestiture (but in a proceeding that predated divestiture -- this was coincidence), SLU was multipled by a fudge factor called Subscriber Plant Factor (SPF) and some more incantations were done to raise the interstate share to some multiple of its true usage. So in 1982, about 30% of local loop cost was interstate, though only about 10% of calls were interstate. Why do this? Because inTRAstate costs were covered by monthly bills, but inTER state costs were covered only by interstate usage (LD calls). Thus LD subsidized local, while the telcos had "plausible deniability" behind the SPF numbers. This whole process was called "separations". The FCC changed the rules and now has an increasing share of the fixed costs ("non-traffic sensitive", NTS) of the interstate share of local facilities (from SLU*SPF*total cost, still probably around 30%) covered by non-traffic-senstive billing (fixed monthly "access" charges). This allows the traffic-sensitive billing (per-minute charges) to be smaller and LD rates to be lower. If, however, your line were ruled totally intrastate, then the local bill would have to cover about 100% of the cost rather than 70%. The FCC has split the difference, but it's all entirely legal and basically necessary under the federal system. >I do not object to volume discounts. But Centrex is NOT a volume >discount.

Cost accounting for telcos is a black art, one which neither they nor the regulators are very good at, but since regular line costs are entirely fictional, Centrex is probably closer to true cost. fred ------------------------------ Date: Wed, 14 Jun 89 18:25:13 SST From: "Mr. James Crooks" Subject: re: Re: Canada - U.S. communications in TELECOM DIGEST V9 #197 Wolf Paul writes >I can see two reasons for separate country codes, one more valid than >the other: >(a) from certain nationalistic perspectives it rankles that Canada > is the only major country which does not have its own country code > and has to coordinate its internal telecommunications affairs with > entities in the U.S. (I don't hold that view, but then I am neither > Canadian nor very nationalistically inclined); and Major, yes. But don't forget the Carribean where they also use plain- jane area codes too. Most of the transborder LD calling in Canada is to the USA - and I'm sure that Canadian calls rank high in US billings too. I personnaly hate calling with a country code - too many digits and a greater chance of error. >(b) Giving Canada a separate country code frees up a few area codes for > use in the U.S., and **lots of area codes** for use in Canada > (this one I consider the more valid reason). You may get 10 or 12 area codes, but the bill to recode all the billing and reporting software (network, billing and reporting) in the relevant Canadian telcos would be in the 100's of millions of $$$ + all the risks of a major network cutover. Now if the US telco's would be willing to fund the project (they would be gaining a few area codes), I'm sure it could be done in 10 years or so. It would certainly help Canada's balance of payments. ISDN numbering is causing problems to and maybe the whole thing can be resolved when a major portion of current users switch over to it (if and when, I should add). James W.

AT&T has their own database. The actual charges for AOSs and other such companies is closer to 15c. It may range as high as 30 depending upon the charges imposed by the BOC, LEC or independant. The overhead charges imposed by the database providers (such as NDC) are generally constant. As I stated in an earlier message, some cards (generally corporate cards) are not in any databases. Also, the mechanisms to get the data used by AOSs (most often dedicated slow-speed modem lines) are slower than those used by AT&T. >In any event, many AOS firms don't really check.

They simply do a LERG checkup on the NPA+COC (actually another database similar to the LERG that include pseudo NPAs for corporate cards), and run an algorithm on certain numbers to check that the PIN is possible, but not necessarily valid. They may have added some sort of after the fact PIN verification on often used numbers recently that could explain the above behaviour. AOSs are not as concerned about fraud (so far) as they are about unbillable billing numbers that may constitute as much as 20% of attempted calls, depending on whether they have individual billing arangements, or through a reseller such as OAN. >NTS, on the other hand, seems to be doing something that I, as an >AT&T customer, find *very* disturbing [Description of method deleted]. >It seems what NTS is doing is using AT&T's calling card system to verify >calls for them, and then place the call over NTS after they use AT&T >to check! You are quite observant. I did explain this in an earlier TELECOM message, but your description hits on the nose what they do. Simply they use voice detection, timing and AT&Ts network to verify calling cards for free. My belief is that this is only done from payphones now, as they got into trouble from doing this from their switches.... payphones are harder to detect. Using this and a valid/invalid cache and they could get reasonable response from repeat customers. There is a device being sold that specifically does this for COCOT type payphones. It is line powered,stores up to a hundred or so CC numbers, and then dials into a special station to deliver call records via DTMF. At less than $200 per payphone, it lets COCOT owners bypass AOS rates and capture the best 80% of their traffic themselves. It also uses this slimy verification tecnique, all the while providing ringback to pretend that the call is going through. The receiver station uses Dialogic boards (they are on the net somewhere) to handle DTMF reception. Anyway, this misuse of the network will most likely become more and more prevelant until some leglislation is passed against it, but even then, it would be hard to prove on a case as small as a payphone. On another note, a discussion in sci.electronics has been going on about payphone phreaking. It might be worth looking at, as I imagine most people on this list are interested. It misses most of the anti-COCOT techniques like chain dialing, and all of the sophisticated methods, but does mention (but not explain - the author had no technical info) a case where a NY airport phone was giving free international calls. Here's how this one worked (and I do mean workED - otherwise I wouldn't post). One specific payphone type, when dialing in a 0, would put itself into infinate time/no money mode (natural for operator calls), whereupon it "cut through" to the switch. The switch had slower timing, so if you dialed in 11 immediately, followed by your international number, you got a free call. It didn't take long for this to be found! -- Paul Guthrie chinet!nsacray!paul ------------------------------ From: John Higdon Subject: Re: Consumer Opts For POTS Date: 12 Jun 89 17:43:25 GMT Organization: ATI Wares Team In article , bet@bent (Bennett Todd) writes: > Our old electromechanical system worked vastly better.

Let's see...on SXS you would frequently get on a noisy stepper and hear crackling noises all through your converstation, punctuated and modulated by other subscribers dialing. Wonderful. The equivalent in Xbar is a sproinging noise at random. Great. Another joy of Xbar is what we call the "killer trunk". Occasionally, someone would call, you would talk, then hang up. And your phone would be stuck for hours. No dial tone, busy to incoming calls. Try to get 611 to fix that (it's intermittant). In fact, I have learned that most COs now turn off the trouble recorder on Xbar; they haven't a clue as to what to do when it drops a card anyway. We nasty people who want features are actually *reducing* the cost to the black rotary-dial customer. It costs the telco nothing to provide call waiting or three way or forwarding, but they not only collect our money for the service, they get more completed calls, timed calls on hold, etc., etc. Over half of my recurring monthly charges is for "advanced" features. Any CO upgrading costs are quickly recovered, not only from these charges, but from the reduced maintenance and plant staff required. Now tell me who is paying for it! -- John Higdon | P. O.

That was the subject of a posting I placed here days ago in response to a misled posting bashing sci.commtech as being just like comp.dcom.telecom and waiting to gobble up useful comp.tcom.telecom postings and drag them into a black hole, far away from comp.dcom.telecom readers!

As I continue to scan the postings in comp.dcom.telecom, I continue to be amazed at how anyone comes to Mr. Martin's conclusion! I's like to say sci.commtech will be complementary to comp.dcom.telecom, but as it was discussed, I think sci.commtech will be so DIFFERENT from comp.dcom.telecom (and the digest) that it will not be of much interest to many who read and post here. Fire engines are not green. You cannot believe Chinese government accounts about the party on Tiananmen Square, and SCI.COMMTECH IS NOT COMP.DCOM.TELECOM!

Ok, here goes. If frankness earns points, this should get a high score. When I first started reading comp.dcom.telecom about a year ago, I couldn't believe that as many uninformed bozos could exist in one place. Questions like "how do I use call waiting?" and "why can't I seem to make my long distance company work from my Time Magazine promo phone?" were all too typical. A number of us in California even created our own limited issue telephone group on USENET so that we could intelligently discuss SS#7, effects of divestiture, generic programming of digital switches, etc. The group is distributed statewide and is even carried within Pac*Bell. Then an amazing thing began to happen. The DIGEST started to improve. Interesting comments began to appear and intelligent replies became the norm rather than the exception. I suspect that your influence has been a factor, but in any event, this forum is now somewhat worthwhile. This is to be contrasted with the drek on rec.* (read rec.audio lately?) and on sci.*. Sci.electronics sometimes appears with fifty posts talking about types of LEDs. Can you imagine the zoo resulting from sci.commtech? One of the justifications is that it would be for those less techincally minded. I was unaware that every article in the DIGEST was technically oriented. Social and political issues are frequently the order of the day, and the explanation of technical issues are usually in terms any layman could understand. If any matters of substance ever did show up on sci.commtech, wouldn't we miss out on the discussion on the DIGEST? If there was frequent cross-posting, wouldn't we be bombarded with the type of buffoonery that permeates the sci groups in general? No, sir. Having seen before and after pictures of the DIGEST, I'm not much interested in purposely throwing a box of nails in the road. Besides, at the risk of sounding elitist, the average person doesn't know enough about the telecommunications industry to even ask intelligent questions, let alone have a legitimate opinion. Nor do they have, as I have found, much interest in the topic, either. My resounding NO vote has already been sent. --- John Higdon | P. O.

I've worked as a telecommunications consultant for school districts, and I used to be an international telephone operator. Point of all this background is that when I started doing my research I used to subscribe to comp.dcom.telecom. I gave up because the signal-to-noise ratio of articles discussing rotary-vs-touchtone, or exchange or line capacity, or other TECHNICAL aspects of the field was too high (that's noise for me) compared to discussion about what people DO with the stuff when they've got it. I just signed up to read the comp.dcom.telecom vs sci.commtech discussion, and found the same S-to-N ratio (in my terms) still persists. I did notice on the way through the messages someone saying c-d-t was formed to take the technical stuff out of human-nets... I think there is room for both groups to exist side-by-side. If people are conscientious about cross-posting and summarising to the other group, those without USENET will not be too greatly disadvantaged. After all, comp.dcom.telecom exists alongside several other groups which might have conflicting interests - rtty in ham-packet radio, for instance; and I've seen discussion of cellular phones in rec.aviation.. basically, USENET is about connections, not boundaries.

There is a working Internet mailing list now -- the Telecom Digest. To set up another list requires a LOT of work, and an agreement from a host to support the mailing workload and the disk space for perpetual archive storage and anonymous FTP access, plus a personal commitment from a moderator or mailing-list maintainer. It makes no sense to attempt to duplicate all this that exists already for the Telecom Digest. (Internet hosts have been becoming more and more reluctant to support mailing lists over the past years -- it is now much harder to set up a new list.) If sci.commtech is formed, I hope that the traffic in that group that is not already cross-posted to comp.dcom.telecom be picked up and included in the Telecom Digest. That would permit the Internet mailing-list community to continue to see these discussions. Unfortunately, it will be difficult to meaningfully participate in them, since responses sent to the Telecom Digest would end up being posted to comp.dcom.telecom instead of sci.commtech. Actually, the whole thing about setting up the new group seems to be a case of trying to fix something that isn't broken. This is very common on USENET; I saw it happening continuously over the past years. (I did have access to USENET for some time, several years ago.) There is a constant effort to splinter groups into more and more narrow topical divisions. I myself can't really understand this motivation -- I usually want to see as much as possible, and fewer wider-ranging groups serve that desire better than many small individual special-purpose groups. Anyway, to summarize, it still seems to me that it is in the best interests of Internet mailing-list participants that the new group NOT be formed, as it would inevitably, to some degree, impact adversely on the existing Telecom Digest / comp.dcom.telecom situation. (By the way, I get the impression that this is a raging and vitally personal issue to some people out there. I do not have much emotional investment in this myself, so I'm sorry if this is being viewed as me "attacking" someone. It is just that it seems more sensible to me to leave things alone since they are working OK now, so far as is apparent to me. I can live with whatever the result is -- it would just be nicer if it came out the way I think best... :-) Regards, Will Martin ------------------------------ From: telecom@eecs.nwu.edu (TELECOM Moderator) Date: 21 June, 1989 00:05:00 Subject: sci.commtech vrs. comp.dcom.telecom {What I think about the matter} When the first message was posted, announcing the plans for this new group, I suggested that telecom readers follow Usenet tradition and cast their vote. As you probably know, the establishment of any new group on Usenet (other than alt.anything) requires 100 more 'yes' votes than 'no' votes to be successful. I originally recommended a vote of yes, in an effort to help the new group get started. I did not see any real problem with another technical group -- even one dealing with communications -- on the net. Now I have read the several objections presented by Digest subscribers, and have had a chance to re-think my own position on the matter. I have to say honestly I still don't see any real problem with it. There are various groups now which discuss telecommunications to some extent or another in addition to the Digest. For example, sci.electronics occassionally touches on telephone topics, such as the recent discussion on payphone phreaking. 'Comp.risks' sometimes prints things of interest to telecom people; and in fact some items have appeared here first and been transported to Risks by an interested reader of both journals. I've also published things here with first were in Risks; likewise, sometimes an interesting article on phones or phone service which has appeared in misc.consumers has been forwarded to the Digest for use. The people who want to read/contribute to TELECOM Digest will continue to do so. I do not anticipate losing any readers or seeing any changes in the basic stuff we talk about here. I could be wrong, of course, I would ask that the proposed new group, if established, immediatly set up an interchange policy with the Digest. Items specifically related to telephones, voice communications and similar should be forwarded here by the moderator, just as I would forward more broadcast oriented stuff to him. It is that kind of a spirit of cooperation that describes what Usenet is all about. I'd like his okay to automatically re-publish something which catches my fancy and would appeal to Digest readers; just as he would have my okay to do the same. My last reading of the interim vote results showed about nine or ten 'no' votes and about eighty 'yes' votes. There is still time to vote as you see fit. TO LEARN HOW TO VOTE: Send email to Bruce, at the address shown in his message here (the first one). I suggest you not indicate *how* you wish to vote, but simply ask him to advise you of the voting address and specifications. Then go do it. Frankly, I expect to see most of you hear after the vote, and for the indefinite future. *NO MESSAGES PERTAINING TO THIS SPECIAL ISSUE OF THE DIGEST WILL BE PUBLISHED OR CONSIDERED AFTER THIS TIME* This special issue of the Digest was only published as a courtesy because I published the original announcement and a rebuttal -- then several more messages arrived. Ordinarily, all discussion pertaining to new groups must be conducted in 'news.groups' and 'news.misc'. Since TELECOM Digest *could* conceivably be affected by the establishment of sci.commtech, this discussion was presented.

PT] ---------------------------------------------------------------------- Date: Wed, 21 Jun 89 23:29:15 CDT From: TELECOM Moderator Subject: Phemale Phreak Indicted In Chicago A federal grand jury indicted a Chicago woman Tuesday for allegedly master- minding a nationwide ring of hackerphreaks that stole about $1.6 million in phone service from AT&T and Sprint. The indictment charges that Ms. Leslie Lynne Doucette, 35, of 6748 North Ashland Avenue, Chicago, and **152 associates** shared hundreds of stolen phone credit card numbers by breaking into corporate voicemail systems and using them as illicit computer bulletin boards to share information among themselves. TELECOM Digest readers, of course, do not need to be told what voicemail is, or how it works. Ms. Doucette and her associates had managed to infiltrate several voicemail systems, seizing unused mailboxes on each, through the manipulation of master accounts located by Doucette. The federal indictment further charges that the ring obtained more $9531.65 in merchandise and $1453 in Western Union money orders by charging them to stolen bank credit card numbers shared among the group on the illicit bulletin board. The government alleges that the value of the stoen voicemail service alone was $38,200. Stolen phone credit cards used at payphones amounted to another $286,362 of telephone service. But the biggest part of the theft, valued at $1,291,362.00 in the indictment, represented telephone service obtained through the illegal use of WATS- extenders installed on PBX lines of companies nationally. By looping through several diverters and including connections established with the fraudulent phone cards, the ring believed they would avoid detection by telephone companies and by the owners of the WATS-extenders. Corporate victims named in the alleged fraud are August Financial Corporation of Long Beach, CA and A-1 Beeper Service of Mobile, AL. Doucette has been held without bond, in the custody of the Attorney General at the Chicago Metropolitan Correctional Center since May 24, when she was arrested in a raid on her apartment in the Rogers Park neighborhood on Chicago's far north side. At the time of the raid, which was attended by agents of the FBI, along with representatives of Illinois Bell Telephone Company, AT&T and Sprint and Chicago Police officers, authorities recovered 168 stolen telephone credit cards numbers, 271 bank credit card numbers, and 39 WATS-extender dialup phone numbers, with a list of the passwords needed to access each. The indictment does not name any other members of the ring, but authorities said the investigation is continuing, and other indictments are expected. United States Attorney Anton R. Valukas (northern district of Illinois) said the indictment is the nation's first involving abuse of voicemail. He noted this is not the first known instance of abuse of voicemail, but simply the first indictment for it. At a press conference Tuesday in the Dirksen Federal Building in Chicago on Tuesday, Valukas noted, "The proliferation of computer-assisted telecommunications and the increasing reliance on this equipment by American and international business create a potential for serious harm." He said that Ms. Doucette was 'first discovered' last December after a real estate broker in Rolling Meadows, IL (suburb of Chicago) reported that hackerphreaks had invaded and burglarized his company's voicemail system, and changed several passwords. Once detected, Illinois Bell set about tracing the calls in cooperation with Sprint and AT&T. Calls into the voicemail system were traced to private homes in Chicago, Columbus, OH, Detroit, Atlanta, and Boston. When those phones had been identified by telco people in their respective cities, audits were begun on the telephone records of the phones involved, which in turn led to voicemail systems and WATS-extenders in companies all over the United States.

I received it via a presentation and subsequent discussion with a Bell Communications Research (Bellcore) employee whose job is supporting the NANP. The NANP ensures sufficient numbering resources are available for World Zone 1 (the United States, Canada, Bermuda, and many Caribbean Basin Nations). Current activities the NANP is working on involve: Numbering Plan Areas (NPAs), Carrier Identification Codes (CICs), 800 Service, ISDN Numbering, 900 NXX Code Assignments, Cellular Dialing Review, Numbering Resources for International Inbound Traffic, Numbering Strategic Planning, and a few other areas. Involving NPAs, the following are major work areas: - Central Office Code Utilization Survey (COCUS) - NPA Code Exhaust Plans This is the "short-term" planning for NPA codes that are nearing exhaustion. This includes utilizing previously unused Central Office Codes, 1+ dialing, etc. - NPA Overlay This is the planning for new NPA code assigning, of which only "5" still exist in the N 0/1 X format. These are expected to be completely exhausted by 1995. - Recovery of Mexico Codes Mexico never has been part of World Zone 1, so its use of NPAs has never been part of the NANP (as opposed to Canada, which has as much right to NPAs in WZ1 as the US). Thus, the NPAs assigned to Mexico are being recovered as part of the NPA Overlay. - 809 NPA Administration As the West Indies are very diverse, geographically and politically, the NANP serves as an impartial body in "governing" administration of this NPA. - Interchangn idiot, or just die on the problem. A couple of years ago, I got a reorder every time I called a North Carolina number. Repeated calls to Sprint repair proved worthless. At one point I was told, "not many people call this area, so we don't know when we can get it repaired. You might try dialing 10288 before the number if you really want to get through." I saved myself the trouble. I went with AT&T. -- John Higdon | P. O.

I think one reason they are not included is that the telco doesn't want you to think more money goes into their pocket than actually does. As far as listing options, etc., Pac*Bell on each and every bill lists all of the services that the subscriber pays for. For instance, it shows each custom calling feature and the monthly charge as well as optional "calling plans" (discounts that cost money). > (2) Elimination of the "federally mandated LD access charges". Since > this charge goes straight to the local service provider as part of > the general revenue stream, there is no need to list it separately, > nor to mandate a particular amount. This is sheer obfuscation. Again, they don't want you to notice what that local service really costs. The LD access charge appears to be analogous to a "dealer incentive" or "holdback". In all the rate negotiations with the PUC and consumer groups that figure never comes up. Then when all is said and done, the telcos get that "few bucks more" added right on top. If you look at the reasons for the charge, you will get even more angry. It was originally designed to offset the new inability of the telcos to subsidize local exchange cost with long distance revenues. From the profits being rolled up by the telcos (at least Pac*Bell), that charge seems a bit superfluous. > (3) Equitable charges for all customers. Includes elimination of CENTREX > service.

Ah, but the little guy pays in full. For the residence and small business, Pac*Bell offers Commstar, a mini-centrex-type service that includes some (but not all) of the features of a standard centrex. It is available for 1(!) to 30 lines. For this service you first get the lines involved at *full* price. Then you are charged $8 a month PER LINE on top of that. ADD to that $2 per month for each optional feature PER feature PER line and things get somewhat pricy. Compare this with *real* centrex where the price per line is less than a stand-alone line and the centrex is included. It also does more than Commstar. So once again the little guy subsidizes the sacred *major* customer. -- John Higdon | P. O.

Levine" Subject: Party Line Attack Ladies Reply-To: "John R. Levine" Organization: Segue Software, Inc. While talking to my cousin who runs an independent telco in rural Vermont, he introduced me to Party Line Attack Ladies, an aspect of telephone practice not heretofore described here. In Vermont, the cheapest service you can order is four-party, and many of my cousin's customers do order it. Traditionally, a four-party line consisted of a single loop of wire running to a neighborhood with four houses in that neighborhood wired in parallel. Nowadays, though, the outside plant wiring is in most cases private line, i.e. each customer has a separate physical loop back to the exchange. To make up the party lines, he ties four loops together at the CO. This has a variety of advantages for him -- nearly all of his four-party customers do in fact have four parties on the line so they're not getting better service than they're paying for, and it's much easier to diagnose line problems, change peoples' service, and rearrange the four-line groupings as needed. It also means that his costs for four-party and private line service are the same even though the rates for private lines are higher (four-party probably costs him slightly more since an operator has to ask for the caller's number for toll calls.) He'd naturally rather have people order and pay for private lines. So he takes advantage of Attack Ladies, local ladies who make extensive use of their party line phones and have strong opinions about people who want them to get off the line to make their own calls. One per line is all that's required. When a customer decides to go private, the modern exchange equipment allows my cousin to put another client on to the same line with the Attack Lady without needing to rewire or change phone numbers.

Mr. Minnig probably thinks I ignored him. Sorry! PT] Heard an amusing story from an employee of my regular fill'er up gas station the other day. It seems that someone in Lebanon has been calling the station's pay phone collect to talk to a friend for hours at a time. The average length of the call was just over 1 hour. The local phone company is pretty much up in arms about the whole deal. Seems that overseas collect calls are EXPENSIVE... :-) If you try to call a pay phone collect from a phone here in the U.S., the operator knows that you shouldn't be doing that. Is is possible to call a pay phone collect from overseas in this manner? Besides larceny and possible intent to defraud, what can the local phone company do with the person(s) even if they do catch them?

Surely the simplest solution if there exist too many phones is simply to switch the ringer OFF on one or more sets. Many of the cheaper phones have a switch for this and for those that do not, simple surgery should do the trick. A question here directed at UK listeners (sorry, no UK.TELECOM ... yet?). Has anyone experience with BT`s 'le bleep' service. Le Bleep is an automated residential answering service/pager combination. I have tried BTs sales line twice, armed with a handful of questions, but the two people I recieved knew about as much about telephones as a teabag knows about .... etc etc. Any comments would be appreciated, particular questions are listed below; 1) How do you enable/disable the service 2) Do you require equipment attached to the phone line 3) Can more than one pager be used with the service 4) Is it possible to call the pager direct (ie, use it as a normal pager) 5) Does the phone ring first for a bit or otherwise 6) (out of interest) If answer to (2) is NO, how is the system implemted, particularly with respect to older telephone exchanges. please reply via e-mail, I'll forward any responses to anyone interested too.

I just made test calls to every out-of-the-way place I could think of on AT&T and every single one of them was carried digitally. Even a call to Washington state, the last hold out of analog connections for AT&T was digital. Or how about St. Marys, KS? Or Thistle, UT?

We also > use nothing but AT&T computers here (even though AT&T doesn't make > them) because of the great service we get from them. Just had a modem problem with calls to St. Marys. A call to AT&T service reached a live person in seconds. My complaint was taken and I was promptly called back by someone in "network". I told him that my Trailblazer was having consistent difficulty establishing contact with another like unit and then he promised to get back to me. Within a couple of minutes my Trailblazer answered what sounded like a "wrong number" (no modem at the other end). Later that day, Alan in "network" called to tell me that the modem levels looked good at each end, so they were going to turn down the trunks between San Jose and St. Marys and test them. He told me that the alternate circuits would probably be OK to use in the interim. They were. Today he called to tell me that they had found timing problems in the main circuits that have been repaired and the trunks had been returned to service. Contrast that with Sprint, where you can wait 45 minutes just for someone to answer the phone. Then you talk to someone who takes your complaint and you never hear anything from them again. If you call back to check the progress of your complaint, you first have to re-invent the wheel to get them to acknowledge your first call (AT&T gives you a ticket number when you first call). Then they either tell you it's all fixed when it isn't, or they tell you that they could find no trouble and that it must be your equipment that is to blame. At no time do you speak to anyone knowledgeable. This fact alone tells me what Sprint thinks of its customers. > And I would be willing to pay a little more for that service.

Recently I've seen some discussion on a local BBS concerning the prefix 10288 (or possibly 102880). It was said that adding this sequence to a modem-dialed phone number will "give cleaner lines." Any truth to that, and what the heck IS this number anyway? Don [Moderator's Note: '10288' is the Carrier Access Code for AT&T. At the time the local telephone companies split away from AT&T, the new rules required that every phone subscriber be allowed to choose which long distance carrier was desired. People who did not return 'ballots' to their local phone company were assigned at random to one of several companies handling long distance calls, including AT&T, Sprint and MCI. The long distance carrier of assignment became your 'default' -- or dial one plus -- carrier; meaning that when you dialed a long distance call, your call was automatically handled by the 'default' carrier. You are free to choose whatever carrier you want to handle your long distance calls. If you do not want the carrier assigned to your line to handle your long distance calls, then you must dial a five digit Carrier Access Code *before* dialing the long distance number. For example, MCI might be the carrier assigned to your line. In order to have AT&T handle the call instead of MCI, you must first dial 10288, *then* the long distance number. If AT&T was your 'default' (or assigned) carrier, then to force the call to be handled by Sprint you would dial '10333' before entering the long distance number. Likewise, MCI access is via '10222', and there are numerous other carriers, each with a five digit code of the form '10xxx' which will handle your long distance call if you dial their code first. The message you saw on your local BBS was probably trying to say that the author felt long distance calls with a modem were better handled by AT&T. Since he did not know for sure what default carrier was assigned to the line he was using, he assured himself of AT&T handling of his call by using the '10288' prefix before each call dialed.

For instance, consider the case of Steve Gescheidler, a resident of north Hammond, living just a few blocks from the Illinois/Indiana state line: he shares a party line with Jesus. When he picks up his telephone, a voice will often be on the wire reading from Ephesians, or bellowing at him to repent before he Burns In Hell forever. Sometimes the voice is trying to sell him spiritually enlightening audio tapes -- Visa and MasterCard accepted, of course. His neighbor around the corner, Judy Maruszczak, has a heavenly instrument also: When she tries to make a phone call, it will often times be drowned out by hand-clapping gospel music. Her VCR also likes to preach to her. The Hammond legal firm of Efron and Efron owns a pious dictaphone machine. When the secretary is in the midst of transcribing legalese, threats of fire and brimstone suddenly are heard on the tape. In addition, their phone system is electronic, and when they put calls on hold, as often as not a few seconds later the hold is broken and the call is lost. Several times per day the phone will ring, and no one is on the line at all. Linda Reynolds, another resident in the area said her television, her VCR and her cordless phone all began urging her down the righteous path last fall. She said sometimes at night the cordless phone begins ringing by itself, and going off hook for no reason, tying up their wire-line. Nine year old Tommy Kotul learned how to find salvation while he was trying to play 'Sports Baseball', an Atari game cartridge. He also said that one day in school, a choir started singing hymns over the school's public address system, which is in the form of speakerphones connected to the intercom phone on each teacher's desk. Although the sanctified interference shows up in the damndedest ways, on all sorts of electronic gizmos, it invariably is on the phone lines of the good (and presumably by now, God-fearing) residents of North Hammond, an Indiana community which straddles the Illinois state line with the communities of Burnham and Calumet City, Illinois to the south and west, and Chicago at it's northwest tip on the state line. So people began asking Indiana Bell, "what the heck is this, anyway?"... WYCA-FM Christian Broadcasters, Inc....that's what it is.... this religious station, operating at 92.3 on the dial, licensed in Hammond, IN, with transmitter facilities in Burnham, IL is the culprit. Operating with an antenna height of 500 feet, and 50,000 watts of radiated power, the folks at WYCA-FM Christian Broadcasters, Inc. are literally *saturating* a two mile area around the northern end of the Indiana/Illinois state line, 24 hours per day, seven days per week. Gescheidler lives about four blocks from WYCA's transmitter. He first began noticing the sanctified interference last fall, and it became louder and louder as the months went on, always on his end. "It seems like when I am in the middle of an important conversation, some preacher always comes on and tells me I'm going to Hell," he said, adding that the phone lines had already gone to hell, and no one seemed to give a damn about it. After complaining several times to Indiana Bell, Gescheidler and his neighbors complained to the Federal Communications Commission, the Indiana Utilities Regulatory Commission, and finally to the radio station itself. No one, he realized, least of all the radio station, was willing to take any responsibility for the problem. WYCA isn't breaking any broadcasting rules according to Paul Gomell, an FCC Chicago office technician whose duties include periodic examination of WYCA's equipment. "The home equipment is probably not adequately filtered," he said. "The problem has nothing to do with Indiana Bell's equipment," said Delores Steur-Wagner, Indiana Bell's community affairs manager for Hammond. "If there are complaints, they should go to the FCC." Chris Alexander, Dallas-based Vice President-Engineering for WYCA-FM Christian Broadcasters parent corporation said, "The signal is so strong, you expect this kind of interference in devices that are not well-shielded. We try to advise people as best we can, and we have worked closely with Indiana Bell and Illinois Bell to resolve complaints." In November, 1986, the station raised its antenna to 500 feet from 400 feet, and increased its power from 30,000 to 50,000 watts, Alexander said. "We made these changes only after receiving permission to do so from the Federal Communications Commission." Alexander said that this change in power and antenna height created a so-called 'blanketing area' -- an area of about 1.7 miles in any direction of the transmitter and antenna -- where the signal is so strong and so permeating, it is literally everywhere, in everything. "Indeed this is the case," said one neighbor five blocks from the site. "I have gone for early morning walks in the open field where the antenna is constructed. In the crisp, early morning air, you can almost feel the signal; smell that ozone; sense the corona." Alexander said, "We operate completely within the law. We observe all FCC regulations at all times." He noted that one condition for the change in antenna height and power output being granted by the Commission was that WYCA was ordered to assume responsibility for correcting certain types of radio interference in an area 1.7 miles in any direction of the station for a period of *one year* afterward. Alexander said during that time they worked closely with the telcos involved and "....anyone who complained about interference was given free of charge the filtering devices they needed...some of our people helped install them....just what the FCC said we had to do, we did it, in the geographic area required, for the length of time required...." Alexander noted one of the first complaints about the increased power came when prosecutors in a federal drug trial in Hammond tried to play wiretap evidence for the jury: instead, the tape recorder offered up hymns and homilies. Paul Gomell of the FCC noted that they have received complaints about the station relating to answering machines, speed-dialing equipment, cordless phones, cheapie phones, hold buttons, Touch-Tone service, and VCR's. These appurtenances and others -- like the preaching Atari game -- lend to the appearance that God is everywhere, at least in Hammond. One Indiana Bell service representative spoke, on the condition that she could remain nameless, saying that the telco had handled over 130 WYCA- related problems in the past year, but Bell spokeswoman Steur-Wagner said the company does not keep track of such things and she had no way of confirming this report. The next step to reduce the interference -- with no guarentees that it will completely end -- is to have all the interior phone wire shielded in steel casings, said Tim Timmons, Indiana Bell's regional maintainence manager for northern Indiana, "...plus of course have good filtering where the phone lines come into the building..." "What a deal!", said Gescheidler. He recently priced the job at $300 per phone from an independent contractor. "Indiana Bell said *maybe* they could do it a little cheaper for us...but they say it is not their obligation to resolve the problem any further." He mentioned that, "...one day some guy from WYCA came here with a phone man; they had some cheapie looking filter they plugged in...it didn't seem to do any good." Although the parent corporation of WYCA in Dallas may have good public relations, the neighborhood says local staff at WYCA-FM Christian Broadcasters, Inc. isn't at all concerned any longer. "They have heard so many complaints I guess they quit listening to them any longer," said a neighbor. "When I called one day -- one day when it seemed like they were much louder than usual -- and asked them in a nice way couldn't they modulate their signal a little better, a lady there told me I was being blasphemous. She told me it was anti-religious to complain. She said I should be thankful that I was able to hear the Word of God, and she hoped I would someday realize I would Burn In Hell without accepting Jesus as my Savior. That's the last time I bothered calling *them* to complain. Now the FCC and Indiana Bell say *they* can't do any more either?" No madame, they cannot. As Chris Alexander, VP-Engineering has explained time and again when asked, the Corporation follows all FCC rules at all times. "We ALWAYS do exactly what the government tells us to do," he said. And Indiana Bell brings the wire to the drop by your house. They say the line is as clean as it can be at that point. You do the rest. An old folk-prayer says, "My Lord....nothing is going to happen that You and I can't handle together. Amen." But one can have too much togetherness, as the residents of North Hammond will attest. Said Steve Gescheidler, "On the radio, they are praying for me. Meanwhile, I am praying for a phone line I can talk on without being disrupted by the choir and the organist."

It supports two kinds of lines and phones. The first is the plain old 2-wire tip/ring DTMF set (although, it will recognize pulse dialers as well). The second is a new-fangled multiline setup which replaced the old key sets. These lines use 3 pairs. I believe they are tip/ring, power, and some sort of digital 2-way communication between the phone (er, excuse me, "voice terminal") and the switch. How does one hook up something like an answering machine or a fax machine to one of the 3-pair lines? We've tried the obvious; just pulling tip and ring out to an RJ-11 and plugging the answering machine in, but that didn't work. In retrospect, I don't suppose there was any reason to think it would work; what I'm calling tip and ring really aren't tip and ring in any normal sense, just the voice signal for the currently active conversation. All the contol information (ring, off-hook, etc) probably go over the digital control pair. What we ended up doing was running an old-style line into the office where our main number is and putting the answering machine on that. When the office staff leaves for the day, they forward the main number's calls to the other line so the answering machine can catch them. It seems like there has to be a better way.

DAK sells a device called the Phone Tap for about $50. It plugs into your phone line and into your tape recorder's "mike" and "remote" jacks. Whenever the phone goes off-hook, the device closes the "remote" circuit and feeds the audio into the "mike" circuit. However... since you're posting from USC, I feel obliged to inform you that the law places some substantial restrictions on the taping of phone conversations. To quote from my local phone book: "According to Federal and State tariffs your phone calls cannot be legally recorded unless you hear short 'beep' tones, consent has been gained from all parties to the conversation, or conversation is preceeded by verbal notification which is recorded at the beginning (as part of the call) by the recording party. Use of a recorder without an audible beep-tone is not permitted except for commercial broadcasting when the person being recorded has been informed. It is a crime under Federal Law for any person, including a telephone subscriber, to wiretap or otherwise intercept a telephone call, unless that person has first obtained the consent of one of the parties participating in the call. Under California State Law, the consent of all of the parties participating in the call must be obtained before a person who is not a party to a call may eavesdrop on or wiretap the call." DAK points out these facts (in briefer form) in their catalog. The Phone Tap that they sell does not generate the 'beep' tones required by the tariffs. So... if you want to use this device (or any similar one) and to comply with the rules and with the law, you'll be required to notify _everyone_ with whom you speak on the phone that the call is being recorded. Furthermore, you'll have to be careful to switch off the device when you, personally, are not using the phone... if the device records a call to which you are not a party, then you will very probably have violated both State and Federal laws concerning wiretapping. My advice is, don't do this.

There is more to call quality than just the amount of noise on the line. Call quality also includes Grade of Service (the percentage of a call getting blocked somewhere in the network); call setup time; and percentage of calls "lost". (May be more -- that's all I can think of right now.) In other words, even if the calls that get through have a fabulous signal to noise ratio, if only one in two calls get through because the IXC doesn't have sufficient capacity to handle all the traffic, the call quality isn't that good. If it takes 35 seconds from end of dialing to beginning of ringing, ditto. If every third call gets dropped out in the network, ditto. (These examples are exaggerated, but you get the picture). Anecdote -- I changed my primary IXC from USSprint to AT&T because the call setup times were atrocious and about one call in ten was dropping out (end of dialing -> silence for about 15 seconds -> dial tone). These were, of course, a small sample and all calls were from Ithaca, NY primarily to New Jersey and Pitsburgh -- Your Mileage May Vary. But, the lesson is, even though the amount of the noise on the line may be very good, the call quality may be poor.

Unionville is just north of Kennett Square (uses 215-444, which IS supposed to be a 7-digit local call from Wilmington, although a recent message from me to telecom indicated 11 digits for the local call the other way around). 347-xxxx from Wilmington is supposed to have NO meaning that I know of. ------------------------------ From: Lars J Poulsen Subject: Re: More on Cellular Overseas Date: 22 Jun 89 16:49:22 GMT Organization: Advanced Computer Communications, Santa Barbara, California The first generation of Nordic Mobile Telephones (Scandinavia's Cellular system) NMT-450 operated at 450 MHz; the new system runs at 900 Mhz.

Pacific Bell only itemizes the monthly service charges for *residential* accounts. For instance: Measured Rate Service 4.25 Touch-Tone Service 1.70 (not actual ammounts) Business customers only get "Monthly Service (start date) thru (end date)" and some amount. Beginning this year Pacific Bell has been sending to every business account holder a "Customer Service Record". These reports are sent according to one of three schedules: 1) annually, which month depends on the last digit of the account number; 2) every month (!); and 3) no record. Each account defaults to schedule #1, then Pacific mails a postcard asking which schedule the business would like to be on in the future. In addition, a report is sent each time there is a change in the account records (service added/removed). These reports are not as simple as the a couple additional lines as is the case with residential service (business accouts are more complicated!) Before they began sending these reports is was a real hassle to find-out what you're paying for each month - you could ask for a "customer service report" (same name) but this would be screen images of what the account reps see (USOC codes only, no descriptions). A few years back I asked for, and got, an explanation for what "Monthly Service" included. Then by doing a simple audit of what services we were using I discovered that Pacific Bell and AT&T were charging for a key telephone system that was removed four years earlier when Pacific Telephone (the old pre-1984 CA) telco) sold my employer a new PBX. We got a refunds totalling $15,000! -Richard Edell (edell@garnet.berkeley.edu) ------------------------------ From: David Lewis Subject: Re: Divestiture, Business and the General Public Date: 22 Jun 89 22:52:31 GMT Organization: Bell Communications Research In article , lars@salt.acc.com (Lars J Poulsen) writes: > In article > ms6b+@andrew.cmu.edu (Marvin Sirbu) writes: > > The subscriber line charge (SLC) is an element of interstate phone rates. > I consider that to be a fiction.

The Subscriber Line Charge represents the cost to the LEC for providing your line with access to interexchange carriers. If you disable interexchange calls from a given line using CPE, you also have the ability to re-enable IX calls from that line without notifying the LEC. As far as the telco is concerned, you have the ability to gain access to IXCs at any point in time; therefore, you should be charged for this access. It is not technically infeasible to (either) block interexchange calls in the LEC network (or) to have the CPE notify the LEC when a given line has IXC access blocked or unblocked. However, either option requires some technical changes from the way the network functions today. Blocking in the network requires a database lookup either at the switch or a centralized database; CPE notification of the LEC is a customer network management-type function which could *probably* be handled by a new Q.932 (ISDN Supplementary Services) message. Neither case, though, is doable today. > I wrote: > >> (3) Equitable charges for all customers. Includes elimination of CENTREX > >> service.

I don't work with Centrex, so my knowledge is limited, but my understanding is that, if you have 400 telephone sets (or modems or whatever), you have the equivalent of 400 loops running back to the CO (whether they be individual loops, or a few multiplexed T1s, or whatever). You're paying the telco for what it costs to run the lines to your locations, install whatever muxes are necessary, and manage the system for you. With a PBX, you pay for however many trunks to the local CO you want, plus the cost of the PBX. If you want 12 trunks, you can have at most 12 conversations outside the PBX at any time. With Centrex, if you have 400 phones, you have the capacity to have all 400 simultaneously conversing outside the Centrex group. Yes, Centrex is a tariff -- but a "virtual PBX"? Not really.

I still think it would be a great convenience. I'm not so sure. The IXC market, even though 90% of the traffic is carried by the big three, is still pretty wide open (I think there are still on the order of 100+ IXCs). There's a wide range of cost, quality, coverage, and so forth. I, as a user, know my needs for interexchange telephone service. Cost may be the driver; service may be the driver; billing quality may be the driver; etc. This fits with the parallel discussion that's been going on -- how would you like it if your midnight data dump from your satellite office back to the main office got routed via Joe's Long Distance Company, which has such lousy sound quality that your holding time doubles because of all the retransmits you need, because the algorithm decided on by the FCC mandates that that's the "best" carrier for you to be carried by? A lot more decides the choice of IXC beyond cost, and the person in the best position to decide is the user.

The commission's order, made public Tuesday, will cut rates for customers with Touch-Tone dialing and those who make long-distance calls. The commission's 113-page decision will not affect the charges for basic telephone service. The changes will be effective July 1. The PSC's order calls for: * A 30% reduction in rates charged customers with tone dialing. For residential customers, the rate will decrease to $1.45 a month from $2.05. For business customers, the rate will decrease to $3.10 a month from $4.40. * A 20% cut in charges for long-distance calls made within the same area code. The specific amount of savings will depend on the distance of the call. * A cut in residential-service-connection charges of 23%. Under the order, the rate will decrease to $36.50 from $47.40. Service-connection charges for businesses will reduce by 38% -- to $52.25 from $84.25. * Lowering access charges that Bell charges companies that provide long-distance service. That provision should benefit consumers, because long-distance companies pass on their access charges to customers, the commission said. The commission said the cost of long-distance calls between area codes should drop by about 10% if long-distance carriers pass on their savings to customers. * Lowering "mileage" charges that are paid by rural customers. Currently, the charges range from $2.05 a month to $16.55 a month, depending on where a customer lives. Under the commission's order, the charge will be $2.05 for all customers who must pay it. * Reducing rates for Wide Area Telecommunications Service, known as WATS, and 800 service. The amount of those reductions will depend on the type of WATS and 800 service a customer has and where the calls begin and end. A Southwestern Bell official said Tuesday that the company was "deeply disappointed by the size of today's revenue reduction." "While it may make for some big headlines, the order does not provide for changes in the regulatory framework that are required by today's increasingly competitive telecommunications environment," Dan T. Hubbard, a Bell assistant vice president, said in a statement. The decision Tuesday stems from complaints filed last year against the utility by the PSC staff and the state's Office of Public Counsel, which represents consumers in utility-rate cases before the commission. The complaints alleged that in 1987 Bell had earned more than $200 million too much from its Missouri customers. Bell has about 1.6 million customers in Missouri; about 750,000 of those customers live in the St. Louis area. Both complaints had sought cuts in basic local service charges. Bell had opposed any rate reductions; the utility disagreed that it had earned too much in 1987 from its customers in Missouri. [Big surprise! WM :-)] [This thing reads like it is heavily padded. I will summarize some paragraphs here: the PSC said that Bell was doing better than when the last rate case was decided in 1983, and tax law changes would help it too. The basic rates weren't raised because they are still below the national average. The Public Counsel was disappointed because the changes will affect only a minority of customers (those with touchtone and who make LD calls -- see, I TOLD you they were the minority! WM).] The commission also rejected a plan by Bell that would have given the utility the authority to annually raise local rates by an amount needed to keep pace with inflation plus a 3% "productivity factor". [I should hope so! -WM] ***End of article*** And, on page B1 (first page of the editorial section): REACH OUT, TAP SOMEONE Court Overrules Privacy On Cordless Telephones by Tim Bryant Is the privacy of your telephone conversation protected by federal law? Not if you are using a cordless phone. The 8th US Circuit Court of Appeals has ruled that the 21-year-old Omnibus Crime Control Act does not prohibit interception of cordless phone conversations. In a unanimous opinion, a three-judge appellate panel said: "Courts have not accepted the assertions of privacy expectation by speakers who were aware that their conversation was being transmitted by cordless telephone." The appeals court ruling, handed down last week in St. Louis, arose from a case in Iowa in which criminal charges were filed against a man who had been unaware that a family four blocks from his house was listening to his conversations over his cordless phone. The man, Scott C. Tyler, filed a civil suit over the matter and said that he would press his case to the Supreme Court, if necessary. "It's been a five-year battle, and this is not over by any means," Tyler said. Tyler, 44, of Dixon, Iowa, spent 123 days in prison on two theft convictions in Iowa. Authorities said Tyler had set up a dummy company to bilk two food distributors out of $35,000 in goods. The case began in 1983 when Richard and Sandy Berodt, who lived four blocks from Tyler and his family, discovered that their cordless phone was picking up conversations from the Tylers' cordless phone. "Based on what they overheard, the Berodts suspected Scott Tyler of criminal activity," the appeals court said in its opinion. The Berodts called the Scott County Sheriff's Department in Davenport, Iowa, and were asked to continue eavesdropping on the Tylers. Although no court order was obtained, the Berodts tape-recorded some of the conversations with equipment that Tyler said the sheriff's department had provided. A jury convicted Tyler of theft, even though the judge refused to allow the recordings as evidence. In July 1985, Tyler and four members of his family filed a damage suit against the Berodts, Scott County, the sheriff and a deputy. US District Judge Harold D. Vietor of Des Moines, Iowa, ruled against the Tylers, saying that federal wiretap laws, the 1968 crime control act and the Fourth Amendment's protection against unreasonable searches and seizures did not apply to cordless phone transmissions. Scott County Prosecuting Attorney Thomas C. Fritzsche said he agreed with Vietor's decision. He added that the appeals court's ruling puts the 8th Circuit "in the mainstream" of recent decisions involving cordless phones. "What gave Mr. Tyler some type of credibility was that there has been a split in the case law that has looked at this type of case," Fritzsche said. "But a whole recent trend of opinions has been away from that type of decision. All the courts -- and there have been three or four of them -- have gone the other way. "Mr. Tyler has ideas that this is a case of burning social issues. It really isn't." Tyler had relied on a case that the 9th US Court of Appeals decided in 1973. In that case, telephone conversations were disallowed as evidence when at least one participant in a phone call used an ordinary phone line. But among the cases that the 8th Circuit cited in its ruling against Tyler was a 1970 case involving former Teamsters union boss Jimmy Hoffa. In that instance, the 7th US Circuit Court of Appeals said there was no "expectation of privacy" for conversations over a mobile telephone. In a footnote to its opinion, the appeals court here said that the 1986 overhaul of federal wiretap laws had changed the definition of wire communications to say that "such term does not include the radio portion of a cordless telephone [call] that is transmitted between the cordless telephone handset and the base unit." "As a matter of federal law, we do not believe the Tylers had a justifiable expectation of privacy for their conversations," the court said. Tyler said it was time for the law to catch up with technology. "Everybody is going to be walking around with a pocket phone in the next five to ten years," he said. "The Fourth Amendment needs to be extended." He said his cordless phone had been a Father's Day gift. "Little did I know it would cause five years of hell in my life," he said. Judges George G. Fagg of Des Moines, Gerald W. Heaney of Duluth, Minn., and Frank J. Magill of Fargo, N. D., issued the opinion. ***End of Article*** [Whew! Fingers are tired! WM] [There is also a sidebar item telling what a cordless phone is. I won't bother typing that in; people here know that... :-) It does mention that "modern cordless phones are equipped to use 10 channels ... Each channel has a digital security code that can be programmed 256 different ways. The result is a 2560-to-1 chance that two cordless phones with channels programmed the same way will be within each other's broadcast range..." That calculation of probability sounds a bit specious to me, but I'll leave the rebuttal up to others for now... -WM] One last comment -- I find it surprising that the article does NOT mention the ECPA in any way. Of course, the court case has to be based on law in effect at the time, but the ECPA has changed things since then, and I would have thought that the writer and editor would have wanted to bring that point out...

The OFF switch on telephones, disconnects the speaker or mechanically stops the clapper on a gong ringer. The ringing circuit is still connected and so absorbs power. The Telco wanted it that way, so they could use the ringer circuitry for loop testing. They also could measure the impedance of your line and tell if you had been naughty and attached bootleg phones. So if you have too many ringers and the phones are not ringing or are intermittent, you have to open up and get at the leads to the ringer or electronic rining circuit. With electronic ringers (the ones that warble) disabling the 1 uF capacitor will do the trick. Note for UK readers: BT approved phones will not have a cap, it is in the primary jack. With an approved phone it can be silenced and the ringer disconnected by removing the lead to pin 3 on the jack (blue with white stripe). As I recall U.K. phones will handle 4 standard ringers. A warble ringer on a modern phone usually consumes about half the power of a standard Plessey gong ringer (old fashioned bell). If the moderator wants, I can produce more drivel on wiring U.K. phones etc. Note that what is public and free information in the U.S. is considered "proprietary" by British Telecom.

She has a roommate who is staying in the old apartment for a short time longer than my co-worker. My co-worker asked for the phone in the new apartment to be connected as soon as possible (the number is to stay the same). I have not asked her, but I assume that she also requested that the old number be disconnected at some date which was later than the request for the new line. The end result is that the new line was connected and the old location is also still connected resulting in two phones in two physically separate locations having the same phone number and both ringing when a call is received.

I'm paying for it. I get to pay more and more for service that is less and less reliable, to the point where I finally decided to shut the danged thing off (which has turned out to be *wonderful* -- I'd never get it switched back on, even if they reduced their rates and got their service stabilized and reliable).

Half the time my phone won't ring when callers try to reach me, and I have to get the guy who is attempting to administrate this system to re-initialize my line, since its parameters are getting hosed somehow. If they could have maintained as reliable and straightforward a level of service, while adding new features and improving maintainability, then I'd be delighted. As it is, they are adding new features and improving their maintainability, at the expense of reliability and simplicity of use. However, I am enjoying the chance to learn that I don't need to be so dependant on a telephone; it is wonderful not having one at home, and at work I can walk down the hall, or across campus, or (if it is long distance) walk to a local mini-mart and use their pay phone.

(Marvelous writing, though. Is our moderator a journalist by trade?) Had WYCA been an AM station, then it would have been perfectly believable. Indeed, "blanketing" by AM transmitters is a common problem. I grew up about 3 miles from the WABC-AM transmitter (which is in Lodi, NJ) whose 50kw 770 kHz signal had a habit of getting into everything, including the phone. People who live within blanket zones routinely pick up transmissions on everything from telephones to dental fillings. It's the "crystal set" phenomenon: Any nonlinear element will rectify the signal, "detecting" AM transmissions, whose transmitted power varies (in the time domain) in accordance with the modulation. In fact, I'm guilty of it myself. I have my ham radio antenna strung in the attic, and when I use a mere 100 watts of single-sideband on the HF shortwave bands, our telephone is clobbered. Of course, the antenna comes within 15 feet of the inside phone wire. (Sticking a "split bead" ferrite inductor on the phone wire didn't solve it, but may help a little; you can buy them at Radio Shack.) But an FM station? Not so fast. FM transmitters maintain a constant amplitude, so if you "detect" them with a simple rectifier, you won't get anything but perhaps a steady DC voltage. (It'll light a fluorescent tube, though, if you're close enough.) Telephones won't detect FM the way they detect AM. I've noticed a faint hum on phone lines caused by FM blanketing, but not the actual modulation. Perhaps WYCA is on AM too. In any case, raising the FM tower would actually lessen blanketing, since the "pancake" pattern of an FM antenna points very little signal downwards. fred (k1io) [Moderator's Note: Well.....:).....I have been 'guilty of it' myself a few times with CB radios and the like. The story was NOT a put-on. And I quite agree with your assessment that FM signals should not operate in the manner described in the story. In fact, people in North Hammond have used your same argument with the FCC: to wit, if WYCA is running so legally all the time, how *possibly* could their signal be so all pervasive, heard everywhere including via my gold fillings, etc. The answer has never been forthcoming. WYCA does *not* have an AM operation. They are strictly FM, and have been since they first went on the air about thirty years ago. I can recall as far back as the middle seventies people complaining about abuse of the airwaves by WYCA. The [Hammond Times] remarked on it occassionally a number of years ago, when the station was in its early days, and sharing studio space with WJOB, an independent AM station at 1230 kc in Hammond. This is a group of people, who in their early days, when FM receivers were not as common as they are now, told their listeners -- and I quote -- "if you don't have an FM radio, you can *still* listen to us: just turn on your television set and tune it as far above Channel 6 as you can; you will probably hear us." In those days they routinely splattered all over their frequency neighbors and could have cared less. Calls to their studio in those days got you an automatic reply: "We operate in accordance with FCC regulations. Thank you for calling. Goodbye." The trouble stopped around 1980 for several years while their antenna was still in South Hammond in the lot behind their studio on Calumet Avenue. They bought the Burnham, IL location in 1981-82 sometime, and still there was no trouble. Once the FCC got off their case a couple years ago, all of a sudden the complaints started coming in again. You tell me. I know the people in North Hammond -- at least the ones who hate WYCA -- would be eternally grateful if *someone* could convince the FCC that there were problems. When I had my little pocket size transistor radio out there, within maybe two blocks no matter *where* I tuned on the dial all I got was WYCA. There is something wrong. Fred, maybe you can intervene. I would *love* to see WYCA get their license yanked.

BT made UKP2437m pounds profit or UKP77.27 per second. [IBM makes UKP170/sec] The profit in 1985 was 1,461m and in 1988 2,292m Dividends have gone from 3.9p in 1985 to 10.5p this year. The chairman had a payrise of 56,000 to bring him up to 282,915 The BT Group has 7,340m in the bank. Income reached 11,071m of which 4,397m came from inland phone calls. The British public spent 1,548m on phone calls to 190 countries overseas. Some of this due to the growth of Facsimile traffic. The Telex usage went down by 21% though. What BT calls Other Servics, including IPSS had an income of 501m. Dispite a profit rise of 6.3% the amount to be used for an Employee Share Ownership Scheme will be only 30m this year against 38m last year.

It seems to be a common practice here for the gas station to have a coin telephone on its line. It's a regular coin line, in that local calls require a coin deposit, but it is also listed in the directory as the phone number for that gas station. The bulk of the telephone usage at a gas station is either incoming calls for the business, or calls placed by customers waiting for work to be done. Some public telephone lines are set up to disable incoming calls, but this would not be a good idea in this application. Since it is a real business line, the owner might actually want to accept collect calls when answering the phone, so it is a little presumptuous of the operator to make this determination beforehand. -- Qualify nearly everything.

I was reading a book on Bell System practices circa 1984 yesterday. It says that physically bridged answering services are now considered extremely obsolete. What they do now is that the answering service installs a peculiar kind of PBX with no regular extensions, a lot of attendant stations, and some DID trunks. When the customer wants his phone answered, he forwards his phone using regular call forwarding to one of the DID numbers. Calls show up at the answering service, the service's PBX can then report the DID number called which tells the service who the call was for. A clever way of using technology. -- John R.

PT] ---------------------------------------------------------------------- From: Frank G Kienast Subject: Quirks of ESS in my exchange Date: 25 Jun 89 18:33:01 GMT I am curious as to how an exchange with ESS can have so many bugs and quirks in it. I have noticed the following over the past couple years since we got ESS. Each of the things described below has happened to me at least several times. Sometimes I pick up the phone and their is no dialtone. The touch tone pad works, so there is a voltage, but no tone. If I hang up and retry several times, eventually I get a dial tone. Often this is preceeded by a series of half a dozen or so rapidly ascending tones. Sometimes in the middle of a call (both local and long distance), I get mysteriously disconnected. All of a sudden there is a click and then silence, but the voltage is still there. The party on the other end notes the same thing. Occasionally, the system won't let me program in call forwarding. I dial 72# and get a fast busy (reorder). I dial 73# to make sure I'm not already forwarding, and get the reorder here too. I try hanging up, making other calls first, etc. and forwarding still won't work. Then an hour or so later it cures itself. Sometimes when you dial three digits that are not a local exchange, you get a recording right away. Other times, you don't get the recording until you dial seven digits. Also, no distinction is made between a number that is invalid and one that is valid but requires a 1 first. In fact, the recordings are used interchangably, with the "you must first dial a 1 when calling this number" being used for a few weeks for both, then "your call cannot being completed as dialed" being used for several weeks. If you listen to a recording until it times out (twice), you get a reorder signal. A few seconds later, it starts playing other recordings, such as "All circuits are busy now", or even "The call you have made requires a 25 cent deposit"! When you call an AT&T LD operator (by dialing 10288 0#, for example), you hear four DTMF tones followed by a loud "clunk" followed by about ten more DTMF tones (these tones sound different from regular touch tones). Does anyone have any ideas what is causing any of the things I described above? I could understand this type of thing with the old mechanical switches, but since ESS has no moving parts, it seems to me it should either always work or not work at all. I don't understand how things can work just part of the time, or work different at different times.

I am going round and round >with USWestComm about this. > [Saga, involving new phone exchange in the area, deleted.] Assuming that the errors happen at a quite steady rate, this is the problem known as "clock slip" or "frame slip" on a digital inter-office trunk. The basic concept is that all the digital phone exchanges and trunks in the USA are supposed to be run from one master clock! That is, the 1.544 MHz frequency on all T1 lines (and related ones on other lines) and the internal clocks of the digital exchanges which pass samples through them are all supposed to be locked together. If they are not, one end will supply bits slightly faster or slower than the other end will consume them. When this happens, and the error builds up to the length of one sample on the trunk, all channels on the trunk drop or gain one digital sample, causing a phase error of 1/8000 second, typically causing the data error you are seeing. So the new exchange, or some of the trunks through it, are not properly phase-locked to the rest of the system. Fixing it is PROBABLY just a matter of flipping a configuration switch (in hardware or software) to establish master clock distribution correctly through the system. The hard part is finding one of the few people in your local TELCO who understands the issue. Keep asking for technical supervisors until you find someone who sounds like they recognize the concepts of master clocks and phase locking and frame slip on a digital trunk. You may have to find a name at the "engineering" department of the TELCO, who normally don't deal directly with customer complaints, and get them to work back from their side. They probably specified the system and would be annoyed that it wasn't implemented correctly. >thanks >hal > >haleden@boulder.colorado.edu Bob Clements, K1BC, clements@bbn.com ------------------------------ Date: Sun, 25 Jun 89 04:11:03 -0400 From: David Smith Subject: Premium-priced call forwarding Reply-To: David Smith Organization: DCSC-ZWR, Columbus, Ohio A member of my family moved recently from one part of town to another about three miles away, served by a different telephone exchange of the same phone company, Ohio Bell. It was essential to keep the same phone number. Ohio Bell residence service quoted the cost at $289 for setting up a service that would refer callers of the old number to the new number and $66/month for measured service. Since someone was going to continue to live at the moved-from residence, he decided to keep the line there, add Phone Forward service to it (at $3/month), get a new number at the new location, and use Phone Forward to send all calls to the new number. The cost for this arrangement was about $42/month -- $24/month less expensive for two lines and a custom calling feature than for a single line with an arrangement it seems ought to be no more complicated than having a central office computer programmed permanently to do the forwarding. What's so difficult about setting it up so that when people dial one number it rings at another number -- so difficult that there has to be a $289 setup charge? And even if that cost is somehow justified, what could possibly justify a $66/month charge on the service once the setup work is complete -- compared to a $16 or $19/month charge for a normal measured service line? Probably needless to say, the residence service person couldn't answer those questions -- the best she could do was to say that the monster setup charge was justified because a lot of paperwork was involved and some kind of physical wire had to be strung and the continuing excessive charge was justified because the wire had to be maintained. What's happening here? ------------------------------ From: William Mihalo Subject: Re: Praise the Lord and Pass the RF Filters Date: 25 Jun 89 23:18:05 GMT Organization: Chinet - Chicago, Ill. Since I live near this radio station, but far enough away not to be affected by it, I thought I'd make some comments. First, the areas that appear to be affected include North Hammond and parts of the downtown area (there really isn't much left of downtown Hammond) which includes the Hammond Times. Earlier this year the Hammond Times published a series of articles criticizing a fundamentalist Christian church with a number of things including financial misconduct. It wouldn't surprise me if the interference is aimed at the Hammond Times. Second, the lack of interest on the part of the FCC in this area doesn't surprise me. The Calumet Region, as this part of the state is called, includes the Gary-Hammond-East Chicago area and the surrounding suburbs. This part of Indiana is quite different politically and economically from the rest of Indiana. The situation is analogous to the Chicago/Downstate Illinois rift across the border. Consequently, few people in downstate Indiana would seem concerned about such a problem. Third, Indiana Bell has never expressed much interest in this part of the state anyway. Illinois Bell ran the telephone company in Northwest Indiana for years. In the 1970's the operation of the telephone circuits was turned over to Indiana Bell, which has its headquarters in Indianapolis. Since divestiture, Indiana Bell has a lock on telephone calls placed to nearby communities (for example I live about a mile from Chicago) but must use Indiana Bell and pay Indiana Bell's tariffs for phone calls that terminate nearby. Alternate long distance carriers are blocked since they can't kick in unless I make a phone call that exceeds a certain distance. The end result of this is that its cheaper for me to call Columbus, Ohio than it is to place a long distance phone call to Chicago. If you complain to Indiana Bell about the problem they just laugh. Finally, there is a Chicago rock radio station that has its frequency near WYCA. Although I'm not affected by the blanketing that is going on in North Hammond, I cannot tune in this particular station. If I try to tune it in, I'll hear the station and WYCA at the same time. These are just a few comments that might enlighten why this situation is occurring. I don't anticipate a resolution of this problem for a >long< time. Bill Mihalo uucp: att!chinet!mihalo or att!osu-cis!david!calumet!wem [Moderator's Note: Your notes are generally correct. Hammond and Whiting used to be *great* towns thirty years ago; but after Gary Works/US Steel and three-quarters of Whiting Refinery/Amoco closed up shop, everything went bust. There is no downtown Hammond anymore. Just boarded up storefronts. All that is left downtown is the Hammond Times, the public business office for Northern Indiana Public Service Company; and of course Jack Hyles' First Baptist Church. The Hammond Times has been on his case for several years regards financial misconduct in the same way the Charlotte (NC) Observer kept hammering on Jimmy Bakker. First Baptist (or at least Dr. Hyles) has some financial interest in WYCA, but I don't know how much. You are correct about Indiana Bell. Illinois Bell had the Hammond/Whiting/East Chicago exchanges for years, and they were more than pleased to pull out and turn it over to Indiana Bell several years ago when the area dried up financially. Is the 219-931/932/933 central office still on Fayette Street, across the street from the Hammond Times? Illinois Bell also had a business office there; that office was closed many years ago. Indiana Bell took the territory over grudgingly; they did it through some slight of hand with Illinois Bell; I never have figured out why. The Chicago Tribune has started breathing hard on WYCA, just as they have been doing to the Reverend Doctor Hyles for about a year now. The FCC may be forced to intervene and stop WYCA from jamming all the other stations in the south suburban area. I don't think WYCA is acting purely out of spite to the Hammond Times though; the station was pulling the same kind of stuff in the early seventies as well. *Then* the FCC made them cool it.

PT] ---------------------------------------------------------------------- From: portal!cup.portal.com!Kenneth_R_Jongsma@apple.com Subject: Automated Operator Services Date: Mon, 26-Jun-89 17:36:40 PDT The following article appeared in the local paper recently. It gives a little more detail on the automated operator services I wrote about some weeks ago. It's fairly long but rather comprehensive, edit as you see fit! (Copied without permission from the Grand Rapids (Michigan) Press, Attributed to the New York Times and local editorial staff) If you make a collect call in Grand Rapids, the operator that comes on the line may not be a human. It could be electronic equipment that recognizes and mimics the human voice. On June 1, Michigan Bell's Grand Rapids based office began using the first electronic telephone operator system in the US, according to Phil Gould, public relations manager for the local office. (Possible exageration here: I have heard of COCOTS doing this, though I haven't seen one. He's probably refering to the local operating companies. - Ken) It's the first test of computer aided telephone equipment that other regional and local telephone companies are expected to embrace as human telephone operators become more costly for telephone companies to retain. Michigan Bell will expand the use of the equipment to Pontiac next and the system should be operation in Detroit by November, Gould said. The BellSouth Corp., which serves the Southeast, will introduce the system later this year, and NYNEX Corp plans to offer a computerized operator system next late next year. It's too early to gauge consumer response to the new system in Grand Rapids, Gould said. "Like any new process, customers have to get used to it." he said. Business customers who are accustomed to electronic switchboards at their companies have embraced it more readily than the general public, he said. "There's still a lot of people that want to talk to an Operator." The telephone companies contend that the systems will greatly reduce the need for human operators and the cost of completing calls at a time when the number of collect and third party calls is increasing. Union leaders say the new technology will provide an excuse for layoffs, and others question the quality of service provided by the electronic operators. The savings will only be for the companies, calling rates are not expected to fall. (Hmm. Sounds like poor PR to me. Especially when the RBOCs are pushing to Rate Cap authority in place of Rate of Return - Ken) "This was bound to happen sooner or later because it's just too expensive for phone companies to keep completing these types of calls with human operators," said John Reddy, a business professor at the Wilkes-Barre campus of Pennsylvania State University. Reddy, who spent 25 years as a Strategic Planner in operator services with the old Bell System, predicted that "electronic operators will eventually replace about half of the estimated 70,000 operators employed by local and long distance phone companies across the nation." For now, though, it's a local phenomenon. The nation's three leading long distance companies - AT&T, MCI and Sprint - say they have no immediate plans to use the technology because consumers place a high value on human operators. Because of the stiff competition in the long distance industry, the carriers are afraid to offend customers by introducing electronic operators. The regional companies have a monopoly on local service (or lack there of! - Ken) and face no competition. Using voice synthesis and voice recognition technology, the electronic operator can make collect and third party calls. It relies on the caller's response from a push button (read touchtone - Ken) keypad, similar to the way current network processes calls made with a credit card. To make a collect call, for example, the caller dials 0, the area code, and the seven digit number. The caller then punches 1 on the keypad to alert the electronic operator that a collect call is desired. (Well, sort of: I tried it out, comments later. - Ken) The computer then asks the caller to state whom the call is from, records the callers response and waits for the called party to answer. The computer informs the called party that there is a collect call, plays back the name of the caller and instructs the party to answer yes or no to accept or reject the call. The automated system recognizes the callers' response and processes the call accordingly. The system, made by Northern Telecom Inc., compares the callers response with thousands of yes and no responses on a digital template. Michigan Bell spent about $2 million to install the system while other companies declined to give any figures. A caller can reach a live operator at any point by dialing a designated number on the keypad. Live operators are needed in emergency situations, when callers are connected to wrong numbers (I always know in advance when I'm going to get a wrong number! - Ken), or when a call is not completed. A caller with a rotary dial telephone can also reach a live operator, by depressing the switchook, said Gould. (Hmmm... And who's going to explain to some novice how long a switchhook press is, or for that matter, what a switchhook is? - Ken) Telephone company executives say they have no plans to reduce the number of operators on staff and that the electronic service is part of an effort to reduce the rising cost of providing live operators. Demand for operator assisted calls is increasing dramatically. The executives say they expect the electronic services to cut overhead by more than half, eliminating the need to hire operators to handle the increasing number of collect and third party calls. Whether human or electronic operator handles the call, the surcharges for collect and third party calls will remain the same. New York Telephone assesses a surcharge of $1.20 to $1.48 for collect and credit card calls that require an live operator. The surcharge for thrid party calls, in which a live operator charges the call to another phone number, is $1.23. By comparison, a credit card call that is processed electronically has a surcharge of 30 cents. In an early trial of the automated systems by Southern Bell in Atlanta, a survey of consumers found that when given a choice between a live operator and and electronic one, 60 percent prefered the automated systems. Customers who chose the electronic operator said they did so because it was a much quicker way completing the call and that they did not like dealing with human operators. Customers who chose human operators said they found the automated systems disorienting because they expected a human operator to handle the call. Few forsee the day when human operators are totally eliminated.

The request, officially called an application for rehearing, was filed minutes before the commission's office closed for the weekend. In its 39-page application, Southwestern Bell asked the commission to accept a plan that linked modernization of its network with a new method of setting telephone rates. The petition says the order "has effectively precluded the company from proceeding with the network modernization plan." The company had proposed spending $180 million to replace 112 electromechanical switches with digital switches and to make other improvements, mostly in rural areas. In return, the company said it would freeze local rates for two years and accept a $19.8 million rate cut. After two years, the plan called for any increases in rates to be based on the Consumer Price Index offset by a 3% productivity factor. [NOTE -- The original article had cited this as being "inflation *plus* the 3% "productivity factor" -- this indicates "minus" instead, which would agree with what smb@ulysses.att.com said in an e-mail to me and which makes a lot more sense! :-) -WM] In Friday's petition, Southwestern Bell also asked the commission to reconsider the reduction in its allowable rate of return to 12.61% from 14.7%. The company says the new rate is the fourth lowest in the country. "We do not take this action lightly," sad Dan Hubbard, the telephone company's assistant vice president for comptrollers and external affairs. "After a thorough review of the ruling, we're firmly convinced this is a devastating order which will have long-term implications for our customers, the state's economic development opportunities and Missouri's telecommunications industry," said Hubbard. Martha Hogarty, the state's public counsel, said her office and the commission staff had opposed Southwestern's rate plan because they believed it "would guarantee automatic increases for local service." Hogarty also contended that using the CPI as a basis for rates was illegal and that the company had planned to modernize its network whether the new plan was accepted or not. In filing Friday, Southwestern Bell beat the deadline to apply for a rehearing by a week, said Kevin Kelly, a commission spokesman. Hubbard said the company "wanted to move very quickly because of the serious consequences of this order." Kelly said the next step would be for the commission to decide whether to grant the request for a rehearing. If the commission grants a new hearing, all or part of the rate case could be reopened. If the commission denies the request, the company may appeal the order in court, said Kelly. ***End of article*** If I see any more on this, I'll try to pass it along...

Not so fast again - to detect AM you only need a non-linear element; to detect FM you need a non-linear element combined with a frequency response that is not flat at the frequency being detected. Seeing as telephony equipment is designed for audio frequencies, it should have a pretty steep roll-off at 100MHz. The oxide on any connector will provide a small non-linearity, and the high field strength should make up for the huge inefficiencies involved. (I once had a poorly shielded turntable that would receive WBCN in Boston from an MIT dorm - I know it was BCN because it would come in clear enough that you could hear the DJ. One of the connectors from the turntable had broken, and I had screwed up the shielding when I replaced it. Of course, there's a world of difference between interfering with a magnetic pick-up signal at 10-20 mV into 47k ohms and interfering with a telephone signal of perhaps 500-1000 mV into 600 ohms.)

" Uh, this wouldn't perhaps be slope detection, would it? Although the amplitude of the signal is constant, if you tune your AM radio right to the edge of the FM signal, you can pick up the change in amplitude caused by the frequency deviation at that point as the carrier is modulated. I've heard FM transmitters on AM radios. It isn't pretty, but it works. "if you don't have an FM radio, you can *still* listen to us: just turn on your television set and tune it as far above Channel 6 as you can..." The channel 6 sound carrier is at 87.75 MHz., or right at the bottom edge of the commercial FM band in the U.S., so this isn't too surprising (back in the days when you could still "tune" a TV set). Oddly enough, we get the Voice of the Lord at home on our phones too, from a nearby 10 KW AM station.

Assuming that the errors happen at a quite steady rate, this is the problem known as "clock slip" or "frame slip" on a digital inter-office trunk.

I had a 1200'er which would work error free for a month or two, and then start to generate such errors, at a more or less steady rate too. To fix it, I would open it up, pop the cover off the relay, clean it with electronic solvent (doing my share for the ozone layer, I'm sure ;-{), and then be okay for two more months. I just bought a new modem, and was surprised to find such a relay still present. I guess they're needed for FCC regulations, or something, but my ideal solution would probably use silicon and *no* *moving* *parts*. One easy way to tell if this is what needs to be done is to thwack on top of the modem.

That's largely the idea. The tranceivers are built into the (nation-wide) net of FM-repeaters covering the country. Because of the size of the cells, the NMT-450 rapidly out-grew its' capacity (nobody had even dreamed it would get that popular) and nowadays NMT-900 is recommended unless you absolutely MUST have nation-wide access. A friend just bought a cellular phone and he said if you wanted a 450 subscription there was a waiting-line of several months while a 900 one you can get overnight. Apparently the Telco is restricting the numbers of 450 users and diverting as much of the traffic as possible to 900. Even in a 900 MHz-system, there's always some overlap between two adjoining cells and a certain "spill" is bound to occur. Due to this, adjoining cells never share the same channels and the net-phone protocol handles the supervision necessary to detect when a phone has moved into a new cell and a switch is indicated. Since 900-cells are smaller, there are never as many phones in any one cell at the same time as there can be in the 450-system, so even with the same number of channels, 900 would have higher throughput. As it is, I believe 900 also has more channels than 450, so capacity is MUCH higher. However, 900 does not work if you get too far away from the urban areas and/or high up into the mountains. I have for a fact used a NMT-450 in the border mountains between Sweden and Norway. The Swedish carrier reached well into Norwegian territory and vice-versa. A rough estimate is that the overlap was at least 6 miles (10 km). NMT phones have a "Nation Select" key where you can switch between the different carriers. This is to prevent the phone from suddenly locking onto the "wrong" cell and causing your calls to be charged extra for "international". This also makes it possible to see how far into Norwegian territory the Swedish carrier reaches. /Torsten Torsten Dahlkvist !

Actually it is possible for an FM station's signal to be AM'ed as well, if the transmitter is mis-aligned. I have seen it happen and I think the circumstances may lend some insight to what may be the problem with WYCA. About 12 years ago, I was chief engineer of my college's radio station (WRPI, Troy, NY, 91.5 MHz, 10,000 watts ERP, 470 ft. HAAT). We would get about 2 or 3 RFI complaints a year almost invariably from someone who lived within a mile or so of our transmitter. These could always be handled by properly orienting their antenna or installing an inexpensive tunable RF trap. According to FCC R&Rs, an FM station can measure its power output in either of two ways: The direct method -- a watt meter installed in the transmission line as it leaves the transmitter; or the indirect method -- multiplying the input power to the final amplifier by an efficiency factor. Even though we determined the power output by the direct method I would still calculate the efficiency factor to monitor the aging of the final amplifier tube. This was usually about 65 percent (i.e. 65 percent of the power going into the final amplifier was coming out of the transmitter as RF and 35 percent as heat). Once, while studying the FCC R&Rs, I noticed that they said that the efficiency factor for indirect power calculation was a number determined by the transmitter's manufacturer. I looked it up for our transmitter, at that time a Gates FM-5H, and the manual said 50 percent. This meant that if we switched to the indirect method and used Gates' efficiency factor of 50 percent we would be legally underestimating our power output and actually running at 13 kW ERP. The next morning before sign-on I went out to the transmitter installed our newest final amplifier tube and spent about an hour adjusting the tuning of the transmitter to the highest efficiency I could and achieved an efficiency of 78 percent. Add to that the fact that you are actually allowed to operate at up to 105 percent of licensed power output and you get 16.4 kW -- more than a 2dB increase in signal strength. I patted myself on the back for improving our reception in fringe areas and headed back for campus. Later that afternoon, I stopped by the station and was told by the station manager that we had received about a dozen RFI reports since we had signed on. People were getting us all over the FM band, on their telephones and TV sets (this is before the days of home VCRs and video games). I drove back out to the transmitter site and retuned it to the old settings and reset the (true) power output to 10kW. I called as many of the people complaining of RFI that I could reach and confirmed that things were back to normal. The following Saturday morning I fed a tone into the control room board and headed out to the transmitter with a spectrum analyzer and 100MHz 'scope to see what was actually going on that would cause all of this interference. I returned the transmitter settings to those of earlier in the week and hooked everything up. On the 'scope I saw that the signal was being AM'ed at about 20 percent modulation with the tone from the studio as well as another 1 MHz wave. The spectrum analyzer showed spurious emissions up and down the band at 1 MHz spacing. I realized that in tuning the final stage for such a high efficiency also caused it to have a very narrow peaked response instead of the broader and flatter response it was supposed to have. This caused the AM'ing. I also figured that some instability caused that 1 MHz oscillation. The symptoms described in the WYCA case sound very similar to those I observed here. It would seem that their signal could use some serious scrutiny with an oscilloscope and spectrum analyzer. This could all be done without their cooperation from any site near their transmitter. If the AM'ing is severe enough you can actually see the signal strength meter on a receiver move in time to the audio.

The first is called "slope detection" and depends on the device doing the detecting to have a slight frequency dependent characterisic. As the frequency changes with modulation, so does the voltage produced by detection and voila! you have audio detection of the signal. A more common occurance involves "synchronous amplitude modulation". If an FM transmitter is not perfectly tuned, its output (amplitude) will vary with normal modulation. The FCC requires broadcasters to maintain this AM component at least 50 db below carrier level, but even at that, given sufficient signal you will easily hear the sermon. From what I've read here, these people might have more synchronous AM than the FCC allows. In any event, I have frequently had to exorcise FM-induced audio out of telephone lines. Not uncommon at all. -- John Higdon | P. O.

Lack of response to call forwarding requests and inconsistencies in how many digits are dialed before a recording or reorder tone could also result from a switch that isn't responding fast enough.

The 1E processor is much less adept at handling calls than the 1A, and since this is, after all, a common-control system, a lot of people going off-hook and dialing is going to make other people wait. Of a smaller possibility: the office has crashed! They're famous for that. > Sometimes in the middle of a call (both local and long distance), I get > mysteriously disconnected.

In all fairness, this could be occuring outside of the office in either the trunk circuits or your LD carrier. This happened to me the other night; I had no dial tone for fifteen minutes and when it came back all of my call forwarding on three lines had been cancelled. This was the processor crashing. A "reboot" clears tmp memory which is where call forwarding is stored. > Occasionally, the system won't let me program in call forwarding. I dial > 72# and get a fast busy (reorder). I dial 73# to make sure I'm not already This is defined as "temporary memory failure". Very common. Generally, it sounds like this: dial 72# [dial tone]. Dial number [two dial tone bursts then immediate busy signal (60 ipm)]. Dial 72# [dial tone]. Dial number [immediate reorder (120 ipm)]. I've heard your way, also. > Sometimes when you dial three digits that are not a local exchange, you get > a recording right away.

This is just out and out sloppiness in your CO. Small telcos usually are plagued with this, but not BOCs. A "1" is not required in my exchange for long distance, so I've never heard that particular recording. > When you call an AT&T LD operator (by dialing 10288 0#, for example), you > hear four DTMF tones followed by a loud "clunk" followed by about ten more > DTMF tones (these tones sound different from regular touch tones). This is very surprising. It is identical to what you hear when dialing "0+" on a CONTAC equipped Xbar exchange. I can't believe that they glued CONTAC into an ESS office. Even a 1ESS can handle equal access in its generic programming. I'd love to hear that one for myself. > Does anyone have any ideas what is causing any of the things I described > above?

The 1/1A ESS is simply an electonically controlled mechanical office. The actual switching is done with little bi-stable relays. Apply current in one direction and they close. Apply current in the other and they open. Why do you think it goes "kaplunk-klunk" when you get call-wasted? It disconnects you from your party, connects you momentarily to the call-wasting tone, then reconnects you to your party through a "conferencing" path. That's why the second beep (klunk) is less violent: you're already connected to the conferencing port. If you don't answer the second call and they hang up, it goes kaplunk. That's you and your party being moved back to the normal talk-path. -- John Higdon | P. O.

The "256 different ways" refers only to control signals; the security codes are designed to minimize the chance that the wrong base station will respond to a handset's keystrokes (or that the wrong handset will ring in response to a base's ring transmission). Two systems sharing the same channel and in an overlapping area will collide and allow eaves- dropping; however, if set to different security codes, the bases/handsets will ignore commands from the non-corresponding handset/base. -- John Cowan or UUCP mailers: ...!uunet!hombre!{marob,magpie}!cowan Fidonet (last resort): 1:107/711 Aiya elenion ancalima! ------------------------------ From: John Higdon Subject: Re: Consumer Opts For POTS Date: 27 Jun 89 08:21:28 GMT Organization: ATI Wares Team In article , bet@orion.mc.duke.edu (Bennett Todd) writes: > [regarding who's really paying for switching upgrades] > I'm paying for it.

With the self-diagnostics and lack of mechanical unreliability, newer switching equipment is an *order of magnitude* MORE reliable and capable of providing basic telephone service.

At least with Pac*Bell (and I assume elsewhere) there is a database which handles "called number screening". When you place an operator assisted call on Pac*Bell or AT&T, this database is automatically checked. If you are trying to place a collect call to a coin phone, it shows on the operator console as "collect denied" and he/she *cannot* override it. I have collect and third-number-billing screening on my home phone(s) and if someone tries to call me collect, the operator will say "I'm sorry, this number does not accept collect calls." Same if you try to bill a call to my number. Pac*Bell customers can call their business office and get this screening free of charge. The front line response is denial and run-around, but if you press it you can get it. BTW, it is this database which made possible the assignment of ordinary numbers to coin telephones. It California, they used to be of the form NNX-9XXX, but now they can be anything at all. Oh, try calling me collect; my number is below. :-) -- John Higdon | P. O.

The above is not always the case: I have two phones with electronic ringers. One, a Radio Shack (ET-100, I think; discontinued model), included a schematic that clearly showed that the OFF position of the ring loudness switch electrically disconnected the ringer circuit. The other, an AT&T Trimline 210, causes the other phones in the house to ring more loudly when its switch is set to OFF; so one would guess that it absorbs no ring power when set OFF.

You'll know this baby by the sound. There are no clicks generated. Local calls go from dialing to ringing to connecting with nary a hard click. Also, the call waiting beep has no clicks surrounding it either. Finally, calling up repair service and asking them may produce the info that it is/is not a DMS-100. Now, when I had this problem, I was able to escalate the problem to the point where a technicial would talk to me, and she changed the line card on my line, curing the problem. Unfortunately, she did not know what was different between the old line card and the new one. She said (as you did) that something was out of phase. She said that she'd continue changing line cards for me until I got a good one, but the first one she tried worked fine. Never had a problem again. The problem is that the whole thing is so damned nebulous that it's impossible to cite an applications note or other document to convince the phone company that there is a problem.

Date: Mon, 19 Jun 89 15:27:43 +0100 From: Charles Lindsey Subject: Hillsborough Football -- Another Computer Connection In the UK, we recently had a major disaster at the Hillsborough football ground in Sheffield, in which 95 people died after being crushed against the steel barrier which is supposed to prevent the spectators from invading the pitch. It is estimated that the pressure per person on the fence, due to the weight of the people behind surging forward, was in excess of one ton. [The computerized turnstile problem was noted in RISKS-8.60. PGN] Now the official enquiry into the disaster is sitting, and the papers are full of reports. At some point, it seems the Police decided they needed cutting gear to use on the fence, and telephoned the Fire Brigade for it to be sent. Clearly, its need was EXTREMELY URGENT. Note that Hillsborough is the major football ground in Sheffield. It must occupy something the size of a city block, and it can be approached from several roads. The following is quoted from the Daily Mail for June 14. Two vital minutes were wasted in helping victims of the Hillsborough tragedy. The fire brigade refused to send vital cutting gear until they knew what street the football stadium was on. Four times telephone operator Susan Davies demanded the address. Then she asked five times what the equipment was needed for. Yesterday Miss Davies told the enquiry ... that the fire service computer would not recognise the Hillsborough ground as a place. 'It needs a specific address and district in order to determine what pumps are required to attend', she explained. 'My training is not to assume what an address is. It's up to me to ascertain that from the person calling'. As far as she was concerned, she added, there could have been several football grounds at Hillsborough. ... The conversation ... went like this: Police: Can we have cutting gear for Hillsborough please straight away? Fire: Just a minute. Right, what's the address? Police: Cutting equipment for Hillsborough football ground straight away. Fire: Hillsborough football ground? Police: Yes, Hillsborough football ground. Fire: What road is that on, do you know? Police: There has been a major accident, all the ambulances are there. Fire: What road is it on? Police: I have no idea. Hillsborough football ground. Fire: What road is it on, do you know? Police: Hillsborough football ground, what road is it on? (this to someone in police control). Penistone Road. Fire: Penistone Road? Police: Penistone Road, OK. Fire: Penistone Road, just a minute. What's exactly involved? Police: It's football, a big match, Liverpool v Nottingham Forest. Fire: Yes, but why do you want us? You said it was an RTA (Road Traffic Accident). Police: No, major incident inside the ground. Fire: Major incident inside. Do you know exactly what it is? Police: No I don't. They want all the cutting gear. Fire: For what, do you know? Police: Hang on a sec. Police: (another voice) Hello. Fire: Hello, now you want some cutting gear. What exactly is it for? Police: ... full explanation ... Fire: Right. OK. Leave it with us.

Greenberg" Subject: Flash Hook & Line Disconnect There is a very interesting curiousity I've noticed here in Rochester since Rochester Telephone went digital. One day, I was playing around with my phone and pressed flash hook repetitively for about 30 seconds. The telephone line died for 2 minutes! If someone were to call it, they'd hear a recording that reported "We're sorry, the number you are calling is out of order, it is a temporary condition, and has been reported". Then, in around 2 minutes, the line would reset and calls could be received or dialed on that line. What exactly is it that happens here? If I do it a lot will it get me in trouble? Does it confuse the telco equipment? Thanks, Daniel ------------------------------ From: "Fred R. Goldstein dtn226-7388" Date: 28 Jun 89 09:45 Subject: Re: Praise the Lord and Pass the RF Filters I think Aaron Heller has it right. Of course, his mention of WRPI brings back memories... I was chief engineer of WSPN in Saratoga Springs when we got the FM license (10 watts at the time) in 1974, and we were on 91.1, vs. 91.5 for WRPI. Now WRPI was the most-listened-to station on our campus at the time, so I wasn't really happy about going only 400 kHz away, but our consulting engineer noted that WRPI's protected zone (60 dB above 1 microwatt per meter, per FCC rules Part 1 if I recall) ended about 3 miles from our tower (high-rise dorm), so we could freely clobber them. Had WRPI been (legally) 2 dB stronger, they'd have prevented us from fitting in! The reason FM broadcasting sounds so good (hi-fi, relatively) is because it has a wide bandwidth. A signal is nominally 150 kHz wide. At 92 MHz, that's about .16% of the bandwidth. If you tune the transmitter sharply enough (as Aaron Heller tried), it'll indeed probably be a bit out of tune by the edges of the channel, causing the FM to have an AM component. It's slope-tuning itself. And that's of course a flagrant violation of FCC technical standards. If, just as a hypothesis, the engineering dept. decided that they "answered to a higher authority" and wanted to "spread the word" without regard for the FCC, then they'd indeed tune for "maximum smoke". BTW, under the terms of the Communications Act, licenses aren't permanent; every renewal must be weighed equally against competing renewals for the same frequency (i.e., applications for new construction specifying the existing station's frequency). This caused two of Boston's big 3 network TV stations to be reassigned! Flagrant violation of FCC standards could weigh heavily in such an application, if somebody in Chicago wanted to apply for a new station on 92.3... fred [disclaimer: opinions are mine alone; sharing requires permission, etc.] ------------------------------ From: "a.v.reed" Subject: Re: AT&T Mail vs MCI Mail Date: 28 Jun 89 17:30:28 GMT Organization: AT&T, Middletown NJ In article , ficc!peter@uunet.uu.net writes: > Would anyone care to give me some feedback on the relative merits of MCI > Mail and AT&T Mail?

I can't comment on the comparison (and since I work for AT&T you probably would be justified in discounting any comaprisons I made anyway), but I'd like to point out that the "user interface" of AT&T Mail is just a "backup" kind of capability - it's there so you can still get to your mail if your UNIX(r) system is down. For normal use, you register your machine with AT&T Mail (no need to buy any special software if you are running UNIX with UUCP), and then use your favorite UNIX mailer to send mail to an AT&T Mail address, such as attmail!adamreed/paper for a hardcopy letter (delivered via USPS) to yours truly. There is also a special address, attmail!dispatcher, for mail to people (or FAX machines etc) without registered AT&T Mail addresses. For example, I use the following sh script to send nroff -mm letters via FAX: NUMBER=$1;ATTENTION=$2;shift;shift (echo "To: attmail!fax!$NUMBER(/$ATTENTION)";\ nroff -mm -rL60 -rW65 $@ | col -bx)|\ /bin/mail attmail!dispatcher I can't comment on how you would do this with MCI Mail, but if I were choosing an electronic mail service my key question would be, "can I use it, transparently, from my usual UNIX system, with mailers and tools I already know?". Could someone comment on how MCI Mail, and other commercial E-Mail services, compare in this regard?

The requests for a stay had been filed in June by the Puerto Rico Telephone Co. and La Telefonica Larga Distancia, which had said the new plan to place a "cap" on the prices AT&T can charge would put the two companies at a competitive disadvantage. They also said the plan would harm the public interest. But the FCC, in a decision reached Friday and made public Tuesday, said that the companies failed to provide adequate reasons for a stay and that the public would benefit from the new pricing. The so-called "price cap" plan, which the FCC adopted in March after a two-year study, replaces a 20-year-old "rate of return" regulatory scheme that had placed limits on what AT&T could earn above costs. Most recently that limit was 12.2%. FCC spokeswoman Patricia Chew said the commission also was reviewing other petitions to suspend the price cap plan, so it was not immediately known if the plan would go into effect July 1. AT&T spokesman Herb Linnen said the company was confident it would prevail. "We expect price caps will go into effect July 1," Linnen said. AT&T last month told the commission it would lower its prices by $140 million on July 1, through reductions in its basic long-distance rates and its special Reach Out America calling plan. In its decision, the FCC said "Price cap regulation offers significant consumer benefits that do not exist under rate of return regulation... In light of the proposed decreases, we believe that the public interest weighs strongly in favor of proceeding with the implementation of our price cap rules." The price cap plan allows AT&T, which in 1988 controlled 68% of the US long-distance market, to raise rates three percentage points less than the rate of inflation in three categories of service: residential and small business; 800 calls; and other business services, mainly for large customers. The FCC has said that the plan is intended to give AT&T an incentive to cut costs and that consumers could save $900 million in charges over four years. ***End of article*** I recall the original announcement of this did appear in the Digest, so I hope this follow-up is worthwhile...

In article , apple!zygot!john@decwrl (John Higdon) writes a fairly reasonable rebuttal, which I liked. He rightly pointed out that I am wide of the mark criticising the technology; what is happening here is inept installation and maintenance. However, I would tend to maintain that inept handling of installation and support of the new digital technologies is extremely common. What I've seen in the circumstances I enjoy matches what I've heard and read about in other places. Faced with costs rising on all sides, a telco buys a new switch (or an organization buys a new PBX) on cost savings grounds, and fails to plan for the necessary (but hopefully temporary) increased manpower costs of additional training and whatnot to manage the switchover gracefully; instead of delivering improved performance, they deliver an immediate severe degradation, which may or may not settle out over time and eventually leave the customers better off. I would hazard that the smart money is on "not". This kind of situation, where a new technology offers real improvements, but is so over-hyped that switchover is botched, is responsible for a large proportion of the traffic on RISKS digest. To provide more detail, the problems at home were mostly of the "incoming callers get forwarded to never-never land", and "no dial tone" variety, and are easily explained by a badly overloaded and somewhat ineptly programmed switch. I am sure that they aren't intrinsic to the new technology; however I am also sure that it isn't coincidence that they came bundled in with it. The problems at work are even more blatently obvious; we hit the capacity of our very old switch, and had to buy a new one (we couldn't even get our current one properly maintained, never mind expanding it). Simultaneously and completely independantly, we had a problem with too few operators, not well enough trained. The new PBX was sold to the folks in the business office who chose it partially on the claim that its new features would allow a smaller number of operators to be able to handle more traffic efficiently, since the operator's console interaction was more streamlined. This may be true; however, in the face of a shortage of operators, and extant problems with their level of training, the new technology exacerbated the existing difficulties. So on one hand I agree that I am wrong to criticise the new digital telephony innovations; they really are technologically superior. I still maintain that I am not imagining the problems they have brought. Even though these problems are a consequence of bad planning decisions, if they commonly accompany "upgrades" to digital switches then they have to be counted as part of the cost of the newer technology. Technological innovation doesn't exist in a vacuum; evaluation of costs and benefits has to take into account the people in the situation, and how they will handle the changes. I am griping that the changes to newer telephony switching systems are often handled extremely poorly, enough to produce an overall severe drop in functionality delivered to the customers. -Bennett bet@orion.mc.duke.edu ------------------------------ Date: Thu, 29 Jun 89 21:50:02 EDT From: "John R. Levine" Subject: Re: AT&T Mail vs MCI Mail Reply-To: "John R. Levine" Organization: Segue Software, Inc. Since someone commented on AT&T Mail, here's my two cents about MCI Mail. MCI recently changed their pricing for the better -- so-called advanced service which gets you such distinctly unadvanced features as forwarding messages used to cost extra but now is the standard interface. Unlike AT&T mail it is not integrated with uucp mail (though there is an undocumented gateway to the Internet -- if you have an MCI Mail account try sending something to the EMS "internet" with the internet address as the mailbox.) There are nice interface programs for IBM PCs (Lotus Express) and Macs (Dow Jones Desktop Express) which let you do your message sending and reading on your desktop machine. Email messages are 75 cents apiece (up to 3K characters) or they have a deal where you get up to 40 email and fax messages a month for a flat rate of 10 dollars. Connect time is always free and they have nationwide 800 numbers. As far as faxes (faxen?) and telexes go, MCI does a good job of both. MCI owns Western Union International, which is one of the major international telex carriers, and has a good two-way gateway to telex. They say that sending an international telex via MCI mail is cheaper than any other way and I've no reason to doubt them. Each MCI mailbox has an associated telex number; telex users can call that number and send a telex and it shows up as a message in your mailbox. This really works, and I routinely use it to send and receive telexes to and from Europe. MCI is also a telephone company, so they also make it cheap and easy to send faxes, by treating "fax" as a fake electronic mail system to which they have a gateway. (They also have gateways to Compuserve and a lot of corporate Email systems.) You can only send text faxes, and can't receive them at all. On the other hand, what do you want for 25 cents apiece? Another facility that is of use is their paper mail. You can have any message run off on a laser printer and mailed; it looks very nice. They have printers in Belgium and Australia so that mail to Europe and the South Pacific usually arrives in a day or two, much faster and cheaper than express mail. If you use Desktop Express you can apparently send quickdraw graphics in your paper messages, though I haven't tried it. -- John R.

I don't remember their call sign, but they referred to their operation as "Inspirational Radio". They transmitted from one of the ridges of the Watchung mountain range, thus putting them well above nearby Newark and most of Manhattan. Car radios within several miles of the station would receive their broadcast, regardless of tuner setting. Several times a year, this same effect would occur even with fixed (home) radios at ranges of over 15 miles. This station operated on the FM band. We thought that their relative height and broadcast power were responsible for their intrusiion on neighboring allocations. Is it possible that radio stations operated by the chosen only operate legally when the FCC is around? -Jim. ------------------------------ Date: Wed, 28 Jun 89 10:11:47 EDT From: jsol@bu-cs.bu.edu Subject: re: ESS overloading It's much more common with DMS switching to be overloaded. I haven't seen an ESS in overloaded state, and I know for sure NET has some pretty loaded CO's (although I haven't seen NYC's phone service, I'll bet they are FAR worse off). Newton MA has a DMS1000 and they have the MF (not touchtone) tones distributed across the call before it is completed. Also, DMS equipment is far flakier than ESS so watch out for it. You can't easily distinguish between a DMS and an ESS 5. They are largely the same technology (hooray for competetion). You pick up the phone, sometimes you hear clicks and sometimes you don't. I think with ESS5 you always hear clicks, so if you don't get a click or two before your "goooooooooooo" (dialtone), then you are probably on a small DMS office. ESSen crash. They definitely crash. I've tried relentlessly to get access to the other switch in my CO, and now I have finally gotten a line on it. Unfortunately this other CO loses it's OE's all the time, so I don't get any better service by having lines on both CO's. I like ESS5 and ESS1[A] as well, I don't like DMS. I would probably get a FEX if I lived in a DMS area, just so I can have reliable phone service. The Cambridge ESS1 is converting to ESS5. I can't wait! Oh, the main reason why ESS has so many bugs in it now is that the BOC's are hiring programmers to work on it, where before, the coding was done by PHD's at ATT Bell Labs.

Robl" Subject: Two-way Radios in Equipment Installation Date: 30 Jun 89 20:10:33 GMT Organization: UNC Educational Computing Service After several recent minor but annoying problems in the installation of remote equipment (terminals, modems, multiplexers, etc.) which required repeated trips back and forth between the terminal site and our computer room, we are seriously looking at acquiring two-way radios to help in such trouble-shooting. (Some of our terminals are located in public areas without nearby phones.) Since readers of the group may have some experience in this area, I'm looking for pointers before we spend any money. (If there's a better newsgroup for this question, please let me know.) Here's a brief description of the application: All we want is two walkie-talkie type sets (no base station with any kind of large antenna). Most of the transmissions would take place between locations in the same building (but several floors apart), but it would occasionally also be helpful to have enough range to talk to sites as much as two miles away. I'm aware that units on any of the so-called business frequencies require FCC licenses. I also think that I have a reasonably good general understanding of the principles of these units. (I've owned scanner receivers for a number of years.) I'm also aware that for the same power, VHF units have greater range while UHF units are better at penetrating buildings. Here are a couple of specific questions: Would a one watt unit have sufficient power for our application? Are we better off with a VHF or UHF system? Suggestions for specific brands or suppliers or even specific units are also welcome. Please reply by email; if there's sufficient interest, I'll post a summary. Of course, if there are considerations or questions that I haven't mentioned that I should look at, tell me about those, too.

Organization: Summit NJ I recently needed to make a long distance call, and the only public telephone available was one of those new private pay phones. It did not support 10xxx LD carrier selection, but my coinless call to '0' got me the local telco operator, who then, at my request, connected me to an AT&T operator. Now, I'd like a little education on exactly how these private phones work; for example, 1. If I am going to deposit coins to pay for the call, what is computing how much I pay? Is it the central office, or is it some computer in the phone itself? 2. Will these phones connect me free of charge to a local telco operator, or could even a single '0' connect me to some pre-selected LD operator? 3. If I make a call from these phones without ever deposting any coins, does the phone owner get any revenue from the call (e.g., in my case, '0' got me to a telco operator, she connected me to an AT&T operator, and the call was billed to my AT&T Calling Card. I wasn't misled by anyone; the call did show up on my AT&T bill a few days ago)? 4.

I could go to Kemblesville, Pa. and try a local call to Newark, Del. I don't have the wording available for such new dialing instruction. I did notice that years ago, I could leave the 1+ off calls made from pay phones on 302-475 and 302-478, which are local to Pa. points, and 302-674 about halfway downstate in Delaware. As for your comment about DC area: What does this mean concerning area code 202? Is it being withdrawn from the Maryland and Virginia suburbs? Apparently you mean that local calls across the area code boundaries (i.e., from Md. to DC & Va., from Va. to DC and Md., and from DC to Md. and Va.) will require the area code. If 1+ is NOT to be used for such calls, it means that: 202 and 703 can NOT be used as prefixes in Md. suburbs 202 and 301 can NOT be used as prefixes in Va. suburbs 301 and 703 can NOT be used as prefixes in DC (local calls within Md. suburbs, within Va. suburbs, and within DC to remain 7 digits) It is apparently the practice anyway that nearby area codes are not to be used as prefixes. At this time (i.e. WITHOUT this revision), prefixes 261 and 621 in Md. suburbs dial 569-xxxx to make a local call to that prefix in Springfield, Va., and 1-301-569-xxxx to make a local call to that prefix in Severn, Md. In NYC, if you are calling within the local message-unit area, you have to dial 1+516 or 1+914 as the case may be on calls to suburban points. (At least the phone book says to do that.) And I believe local calls from areas 213, 818, and 415 in California to neighboring area codes are 11 digits. ------------------------------ From: Dell Ellison Subject: Re: LD carrier span comparisons Date: 28 Jun 89 18:10:10 GMT Organization: AG Communication Systems, Phoenix, Arizona In article , cblph!grs@att.att.com writes: > Steve Elias suggests that we discuss perceived quality on a carrier by > carrier basis for calls between various cities.

The carriers have enough capacity problems right now in downtown metropolis that reserving channels for 666 channel radios is the least of their worries. There will always be others with radios capable of more channels to pay the bill, and that's all that matters. Further, each site is assigned a discrete set of channels to operate on; even though coverage overlaps greatly in a metro area, it would be difficult to fully accomodate 666 channel units in peak periods--there just isn't enough sites with the right channels at the right times to accomodate your scenario reliably.

A recent ruling by the NJ Board of Public Utilities changes that. The ruling makes all calls within a municipality local calls. Many NJ municipalities are smaller than a CO serving area. Others are split between two or more CO serving areas. The effect of this ruling is that calls to different numbers with the same CO prefix are billed differently. The determination is made based upon the customer's post office address. For example, a customer calling from a 647+ number in Harding Township who calls a 267+ number in Harding Township is making a local call. But the same customer who calls a 267+ number in Morris Township is making a toll call. This probably plays havoc with a number of ARS algorithms, and once again makes it impossible to know, when you make a call, whether or not it is local. -- Dave Levenson Voice: (201) 647 0900 Westmark, Inc.

In addition to responses to this group, I have received nearly a dozen mail responses. The following is a summary of responses so far. Sometimes not receiving a dialtone is caused by the fact that the switch scans the subscriber loops. A bug in the software occasionally causes it to go off into oblivion until it times out and resets. (No explanation yet for the sequence of ascending tones that are sometimes heard just before receiving a dialtone.) Getting disconnected in the middle of a call (which I forgot to mention happens on local calls as well as long distance) could be caused by the failure of the (mechanical) relays which are driven by the ESS software (I had thought before that electronic switches were used). Inability on occasion to program in call forwarding is caused by a temporary lack of available memory, which is dynamically allocated when the request is made. Someone asked me if the 72# and 73# codes were a typo (they thought they were *72 and *73). I checked and 72# and 73# are indeed correct, but I tried *72 and *73 and these work also. Apparently they are interchangable. Sometimes receiving a recording after dialing three invalid digits, and on other occasions not receiving any response until seven digits are dialed may result from changes to the on-line database which are constantly being made due to trunk changes, the addition of new exchanges, etc. ESS screens each digit as it is dialed, so the capability of detecting an invalid sequence before seven digits are dialed is built in. The mixup between the "You must first dial a 1" and the "Your call cannot be completed as dialed" recordings is apparently a programming mistake. (The software comes with the switch, right? Wouldn't all switches of the same type and company have this problem then?) Getting different recordings after the first recording times out is also a programming problem (Hmm.. maybe they used GOTO's to branch to the routines that play the various recordings and forgot the jump out between them :-)) The tones heard when connecting to an AT&T operator are MF (Multi-Frequency) tones which are used by the network for routing calls. They are combinations of 700-900-1100-1300-1500-1700 Hz. Apparently intermediate routing is required because my area is served by a small telephone company that is not a former part of Bell. In response to questions I have received: I am in the 804-979 exchange. The local phone company is Centel. I believe they have a Northern Telecom switch. Finally, I'm wondering if someone could recommend a good book on ESS. I have only a very basic knowledge of telephone switching systems, but have a good understanding of programming (from high level languages down to assembly language) and electronics. I'm looking for such things as the history of ESS systems, problems that were encountered in their design and how they were overcome, information on the hardware and software typically used (type of processor and operating system, some sample flow charts or code, etc.), a listing of the various ESS versions (#1,1A, etc.) and their specifications, etc. Please let me know if you have any recommendations on what book(s) to read and where they can be obtained.

Using a Touch Tone phone, get dialtone and dial one digit. Immediately after you take your finger off the dial pad, you will hear a very short burst of dialtone before silence. This means the switch is a DMS. Certainly works in Southern California. So the sequence is: Dialtone, Touch Tone, dialtone, silence. A X-Bar or AT&T ESS will have the following sequence: Dialtone, Touch Tone, silence. There are of course other quirks that identify a DMS, but this is a quick, certain, cheap and dirty test.

The methods they use are not as complex or accurate as most LD carriers. They mainly have NPA+NXXs stored in a table mapping to rate centres. They then store latas and V&H coordinates of the rate centres and compute distance to look up in mileage band tables for combos of inter/intra state/lata calls. Tax is often added at a highest possible rate. In short, they take shortcuts, and generally compute a higher than normal rate to cut down on the amount of memory needed for the ROM based tables. These tables are often out-of-date. Some of the newer phones have modems in them to receive downloaded rates from a PC program. > 2.

Premises Equipment In a conversation with jsol on Sunday, we discussed the merits of speed dialing. As all TELECOM readers probably know, you can get 'speed dialing' (sometimes known as convenience dialing) from the telco, as programmed in the central office switch, or you can purchase a variety of equipment which maintains the speed dialing repretoire at your own premises. Which is better, if either? Is it purely a matter of personal taste, or can you suggest reasons why providing it for yourself might be preferable to that version sold by the telco and maintained in the CO? Just wondering. We came to the conclusion it was purely an individual choice, with no apparent advantages to either; certainly not as long as the CO version can be programmed with ease from your own phone.

Last question first, no you can't; MCI and AT&T don't handle calls that don't have at least one end in the U.S. French payphones are tons of fun. There are two kinds, the kind that take coins and the kind that don't. In Paris, they're all coinless except for the funky little ones you find inside stores, other places they're being converted to coinless from coin as they get around to it. To use a coinless phone, you need a Telecarte (accute accents over the first two e's) which is sold at all France Telecom offices which are generally inside or next door to post offices. They come in two (logical) sizes, 50 units and 120 units. Last year the 50 unit card cost F40 and the 120 unit card cost F100, I don't know if they've gone up. All calls in France are charged in units, with the time per unit depending on the distance, ranging from 12 minutes for a local call at 2 AM to 1.2 seconds for a call to the South Pacific. For calls to Spain, I'd expect a unit to be worth something between 30 seconds and a minute, depending on the time of day. It's all in the front of the phone book. To use your card, you stick it in the phone and wait a moment, and a little display shows you how many units you have left. Then dial 19 for an international call, get a second dial tone, and dial the country code, 34 for Spain, and the city code and phone number. When the calling party answers, the phone starts counting down the units until you hang up. Then it tells the little microprocessor in the card how much it's worth and gives you the card back. I've never used up a card, but I presume if you run out of units if cuts you off and you have to call back with a fresh card. Once you get the hang of this it's very handy. The price per unit is about the same as you'd pay for a call from a regular phone. If you have to use a coin phone, you dump all your change into it and it eats the coins as needed, giving back the ones it didn't use. You get no change. It is still possible many places to call from a post office and pay them, but I can see no advantage to doing so unless you know you'll never place another call and the one you're making will cost less than F40. (F40 is worth about $7.00.) For the particular case of calling back to the United States, you can get an AT&T or MCI operator by calling 19-0011 or 19-0019 and place a calling card or collect call to the U.S. In a coinless pay phone you need a telecarte but it won't deduct any units. -- John R.

Yes, they have prepaid cards. and you can buy them in post offices, and probably other places as well. If you can go to a post office during normal opening hours, there may be a better solution: use one of the phone booths within the post office itself. In many places, you can pay to the cashier as you leave. I use this whenever I don't have change for a coin phone, or the streets are too noisy. >Stupid question: can I make any use of an MCI or an ATT phone card >for that purpose?

Duke University and Durham NC have a rather interesting set of telephone interactions. Durham (a satrapy of GTE South) has a relatively bad service reputation. The area is undergoing a period of rapid growth and new CO numbers are being opened rather quickly. As they open the new numbers, they are not necessarily installing new switches. Some parts of town get modern equipment and good service, and other parts get stuck with the older stuff. In fact, I can generally know how reliable the service to a given number is going to be by just the CO code. I even asked specifically to have my service provided by one of the new COs. Going from my home to Duke, or any computers in the newer COs will be fairly good (only fair :-( ) but bbs's in other COs are subject to the }}i}} type interference.

This is easier said than done. Duke University's phone system is almost totally independent of the Durham phone system. It even has its own tarriff hearings before the state PUC. It has 3 CO codes (684,681,680) and leases ists own set of AT&T LD access trunks. Early this year, the University cut over to a 5ESS all digital switch. This has brought the usual set of settling in bugs. The AT&T PBX that Bennett complains about is the PBX for the Department of Radiology in the Medical Center and is actually on the floor next to the 5ESS (I think, it may be in the hospital, Bennett?)

(Carl Moore) Re: How Exactly Do Private Pay Phones Work? (John R. Levine) ---------------------------------------------------------------------- Date: Tue, 4 Jul 89 21:02:11 CDT From: TELECOM Moderator Subject: A History of the Rogers Park Telephone Office The information in this article comes to me courtesy of the Rogers Park Historical Society here in Chicago. Their source of information comes from notes prepared March 5, 1958 by R. L. Mahan, an employee of Illinois Bell, for the occassion of the 75th anniversary of telephone service in Rogers Park, the Chicago neighborhood in which I reside. September 15, 1883: Rogers Park was served by a toll station from Chicago. The charge was 25 cents for 5 minutes of connection. The name and address given in the directory of the Chicago Telephone Company was simply, "Rogers Park, public toll station # 1". September 15, 1886: In the Chicago Telephone Company directory issued this date, two toll stations are listed, with the second one being "Dr. C.H. Burbank, drug store, toll station # 2". July 15, 1889: The south edge of the present (1958) Rogers Park office (that below Devon Avenue) was annexed to Chicago, as a part of the city then known as Lakeview. April 4, 1893: The territory east of Kedzie Avenue and between Howard Street and Devon (most of the present [1958] Rogers Park office) was annexed to the city of Chicago. This included the villages of Rogers Park and West Ridge. December 1, 1895: The Chicago Telephone Company announced the establishment of a telephone exchange in Rogers Park. The proposed rate for service was $42 per year for local community service, with a toll fee for calls to Chicago. January 1, 1897: The wiring and installation of the exchange was complete, and it opened for business this date. The switchboard was located in the drug store at the corner of Clark Street and Lunt Avenue, and was operated by the wife of the pharmacist and her family. 1903: At year end, stations in service throughout Rogers Park totaled 372, versus 255 the year before. February 1, 1905: The switchboard was moved to the building at the rear of the drug store (actually 722 Lunt Street). Chicago Telepone Company announced that effective that date, service would be provided 24 hours per day, seven days per week. Prior, the board had been open during the day and early evening hours, and closed on Sunday. The residents of the community had a 'gentlemen's agreement' with the operator: Calls would not be placed during overnight hours or on Sunday when she was off duty except in cases of emergency. In a middle of the night emergency, a loud bell connected to the switchboard rang when a phone went off hook and it would awaken her, sleeping nearby. September 1, 1909: The street number of the phone office changed to 1754 West Lunt, when all house numbers were changed to conform with the new street numbering system in Chicago. 1909: The village of Birchwood (including the Germania community in the far south end of Evanston) was served from Rogers Park on "Birchwood" theoretical prefix. March 6, 1915: Rogers Park office cutover; many number changes were involved. The "Birchwood" theoretical prefix was discontinued. The office moved to its present ([1958] and still, in 1989) location, 1622 West Pratt Avenue. April 24, 1915: Area north of Howard Street, east of the Elevated tracks and north to the south boundary of Calvary Cemetery (neighborhood known as "Little Germania") annexed to the city of Chicago, and served by the new "Rogers Park" prefix. March 13, 1920: Area along the lake front which had been served by the Edgewater office (1007 stations) was transferred to the Rogers Park office. The "Sheldrake" prefix was started to accomodate these phones. Some of the residents in the area had "Rogers Park" numbers, and as nearly as possible kept the same number, but with "Sheldrake" as the new prefix. Records indicate that a John Townson, whose telephone number was formerly "Rogers Park 6" was transferred to "Sheldrake 1". 1921-23: The Chicago Telephone Company was aquired by the rapidly growing American Telephone and Telegraph Company, and over a two year period, all facilities of Chicago Telephone were transferred to the control of the newly formed corporation, "Illinois Bell Telephone Company". Throughout its history until now (1958), Illinois Bell was never owned exclusively by AT&T. Although AT&T owned and still owns about 95 percent of the stock in the corporation, about 5 percent is owned by private investors, who retained some stock rights from their prior ownership of Chicago Telephone. April, 1925: "Briargate" opens as a third prefix in the area. April, 1928: "Hollycourt" opened as a fourth prefix. September, 1940: "Ambassador" opened as a theoretical prefix in the Sheldrake exchange. September 18, 1948: Most of Chicago, including Rogers Park had been converted to automatic dialing in lieu of manual calling. The Rogers Park neighborhood exchanges converted to the two letter, five figure numbering system. The third letter of the exchange name became the first digit of the five. Old style numbers less than four digits took leading zeros as filler when the dial conversion was complete, i.e. a number such as ROGers Park 6 became RO-4-0006. July 25, 1949: "ROgers Park-1" opened as the sixth prefix in the area. December 31, 1950: Stations in service on six prefixes in Rogers Park totalled 53,055. Prefixes were "ROgers Park-1", "ROgers Park-4", "SHeldrake-3", "BRiargate-4", "HOllycourt-5" and "AMbassador-2". April 28, 1957: "BRoadway-4" opened as a theoretical prefix in "BRiargate-4", which it will eventually replace. <><><><><><><><><><><><><><><><><><><><><><><><><> At the bottom of Mr. Mahon's notes, dated in 1958, the following additional notes had been written in: February, 1961: All number calling prefix 338 was opened. Ironically, had we still been going with exchange names, 338 would have been presented as "DEvon-8", a logical choice, the main street in the area being named Devon. September 16, 1962: Direct distance dialing for station to station calls became available to phones in the community. We can call many places in the United States by just dialing three more digits at the start of the number. <><><><><><><><><><><><><><><><><><><><><><><><><> Rogers Park Telephone Statistics: other/ Year Total 1-party 2-party 4-party business 1900 85 unk unk unk unk 1905 372 23 unk unk unk 1910 2117 172 169 1553 243 1915 5322 700 388 3657 577 1920 12,376 2073 1072 7574 1657 1925 23,648 5355 5202 9572 3519 1930 36,691 11,861 12,823 5725 6282 1935 35,732 8556 12,760 8568 5848 1940 40,527 10,055 19,284 4410 6778 1945 43,010 11,994 22,190 2649 6177 1950 53,055 17,984 22,804 1257 11,010 1955 66,547 29,020 18,869 -- 7 18,581 Notes: 1. During the depression years 1930-35, many people could not afford phones and had to give them up. The net decrease in that period was almost 900 stations; this is the only period in which there was a decrease rather than an increase. In that same time period, many people chose to give up private service and take the less expensive party line service. 2. Illinois Bell Telephone Company, successor to Chicago Telephone Company, discontinued offering four party service in 1949, but 'grandfathered' it to existing customers. By 1955, it was almost gone. The last of the four party subscribers dropped out about 1962. 3. Several large business phone installations occurred during the 1950-55 period, and payphones became much more common, appearing on street corners, the elevated train platforms, etc. In addition, Loyola University of Chicago greatly expanded its phone service during the early 1950's. This is shown in the large increase in other/business category in 1950 and 1955. 4. The largest single increase in subscribers was during the 1900-1910 period, when the number of subscribers increased more than twenty fold in that decade. The increase between 1905 and 1910 alone was six fold. Having the exchange staffed full time in its own office became a necessity! <><><><><><><><><><><><><><><><><><><><><><><><><> Long after this was prepared and presented at an IBT Company anniversary dinner, we added the prefix '973' in our area; then five years ago we added '508'.

I think what was meant was that if a town is connected to more than one exchange (local calling area boundary) which would normally cause a toll be charged, that now that call is local. New England Telephone has had that in place for years. You sometimes have to dial 1 first even for local calls in NET's rural areas, but the DPU here guarantees the same thing. Calls from anywhere within a municipality are local calls, even if the exchange boundaries differ. It's a billing hack. They just simply have to change their billing records so that the call is local. --jsol ------------------------------ Date: Mon, 3 Jul 89 15:56:54 EDT From: Carl Moore (VLD/VMB) Subject: I Tried a Local Call From Pa. to Del.

If you place an inter-lata calling card call from one of these things, it will invariably route you to an "alternative operator service" such as NTS or ITI who will charge you several times the AT&T rate for the call. For intra-lata calls, it depends on the state tarriffs; if your call is carried by a real phone company such as AT&T, Sprint, or the local BOC, the phone owner doesn't get a cut. If it's an AOS, they probably do. I've seen ads in the business pages of the local paper saying "get $1.00 per call when customers use your payphone." By the way, the magic of equal access is now coming to real telco pay phones, so that if you dial 0+number your call gets routed to the LD carrier of the phone owner's choice. If it's NTS or ITI, you pay the same exorbitant rates. Check the instruction plate of the phone; it legally has to say who carries the LD calls, and the operating companies are pretty good about making sure they tell the truth. (They're no fonder of NTS or ITI than is anyone else.) > 4. Am I entitled to 10xxx LD carrier selection if I use > one of these phones? Yes you are, although many of them are programmed, probably illegally, to make that difficult or impossible. I've also had them ask me for $9.95 when I dialed 950-1022.

It's attributed to Associated Press: Tokyo to Add 8th Digit to Phone Numbers Move over Paris, Tokyo will join you in the ranks of cities with eight digit phone numbers. Nippon Telephone and Telegraph Corp. said Tuesday the change from seven digit phone numbers in Tokyo will take place January 1, 1991. Subscribers will add a 3 at the beginning of their seven digit numbers. The national telephone utility said a shortage of exchange numbers began in 1981 as demand increased for facsimile and microcomputer communications on top of demand for regular telephone lines. Some eight digit phone numbers were given to pocket pages in 1987, and in 1988 some new subscribers for regular telephone service received eight digit numbers, NTT said, but by early 1991 the shortage will be accute. (End of Article) This started bothering me when I first heard France was going to eight digit numbers a few years back. It's probably just my American Provincialism, but it seems as if "the rest of the world" is ignoring the Bell Labs studies on how easy it is recall numbers. I figured it was the French desire to different from the rest of the world, even though they had already implemented the equivilent of an area code (city codes). Now the Japanese are going that way. What am I missing here? What's wrong with a "downtown" city code and a "suburb" city code? If a country doesn't need a full up 3 digit area code, the equipment could be easily programmed for less, but the concept of an area (city) code makes a lot more sense than making everyone dial (and remember!) and extra digit.

I don't know much about the details of call completion other than that calls from regular payphones are routed to equipment at the long distance company that looks up the price and listens for the sounds the phone makes when you put in the money, and sends a signal back to the phone when the call is answered to tell the phone whether to drop the money into the coin box or the coin return. COCOTs do it all themselves with internal microprocessors. Until recently AT&T was the only LD carrier that had arrangements with the local telcos to handle coin calls. With the recent extension of equal access to pay phones, MCI and Sprint are now phasing in coin service. I can dial, 10222-1-number or 10333-1-number from a payphone here in Cambridge and I get a computer that sounds exactly like AT&T's asking for exactly the same amount of money that AT&T asks for. The volume and background noise are different, though. I don't know whether MCI and Sprint are subcontracting their coin service to AT&T (as they do their directory assistance) or if it's just that everybody buys their coin call processing equipment at the same place. I also note that if I dial 10222-0-number or 10333-0-number, I get MCI or Sprint recordings asking me to dial my calling card number, but the only card number that works is my New England Tel number (which is the same as my AT&T number), not my MCI or Sprint number. I don't understand that at all. -- John R.

Lots of up-and-down on the hookswitch is apparently interpreted as something wrong with the line or instruments, and one attempted corrective action is to remove the line voltage completely for a while with the hope that whatver's causing the problem out there will eventually reset itself and be quiet. My office [Dunellen NJ] does the same thing. I discovered this while playing around with my series-resistance feature, that simply increases the DC resistance of the phone until the line card gives up. With older offices the finder used to go crazy, and oscillate back and forth. The DMS cards have hysteresis, so if you turn this thing down until it disconnects you have to turn it up a ways again to get the dialtone back. What really annoys me is the automatic diagnostics the office does around 2am every night.

Sorry, I've seen somebody's poster on a similar question, but it's gone (:-)... I want to know codes, which allow me to route my long-distance calls through various LD companies (I'm going to try MCI and US Sprint, not saying about AT&T)As far as I know one should just dial five digits before the actual number - and this way the call will be sent to a proper router. Questions: 1) What are the codes for AT&T, MCI, US Sprint (and others, if they exist)? 2) Where should I put that code? The # is: 1-xxx-yyy-yyyy Where the code should be placed - before 1, after 1 but before xxx? Thanks to everybody who answers (without flames, I mean!). Uri. [Moderator's Note: The three main codes are: MCI = 10222; Sprint = 10333; AT&T = 10288. There are many others; not all long distance carriers work in all parts of the country. Consult the long distance carrier of choice and see if they accept incoming traffic in your community. As for the placement of the codes, if the carrier chosen is the default carrier for your line, then you *do nothing*. Just dial the call normally. If you wish to route the call to one of the other carriers, dial their code first, and then the long distance number. For example, to call 1-310-555-2368 using Sprint, you would dial 10333-1-310-555-2368. To dial it via MCI you would enter 10222-1-310-555-2368. Maybe one of the readers will send you a complete list of carrier codes; you sort them out.

Some telephones had memories - 1 lost memory everytime there was a commercial power flux. Some did not have memories. Some were pulse only, others were tone-dial. The only solution that allowed the user to use a short-dial sequence from any phone in the house was to use the CO-based solution.

But the article is hardly one to bring comfort to its readers. It is one of the first to acknowledge that Peking is a city living in fear. "In recent days," it says, "people in Peking who normally love to make phone calls have suddenly become cautious, and many of them say on the phone `Let's write or chat face to face instead, otherwise we might get into trouble.'" There are rumours that all phones are being tapped, or that advanced scanning equipment is being used, according to the article, entitled "You do not have to be on tenterhooks when you make a phone call". Mr. Zhao Jizhi, a senior engineer at the telecommunications management bureau, said that half of the 280,000 phones in Peking were computer- programmed, and could not be tapped. The other half could be tapped, but were not -- there were far too many of them. And in 30 years, Mr. Zhao had never heard of scanning equipment. ================================= End ========================================= Information Exchange Rupert Zhu (in Canada) rzhu@violet.waterloo.edu (Elsewhere) ------------------------------ From: Russell Shackelford Subject: Will This Work and is it Legal? Date: 7 Jul 89 06:06:26 GMT Organization: Georgia Institute of Technology Scenario: exchange "b" that has local calls to exchanges "a" and "c". Calls between "a" and "c" are toll calls. 1. If I get a phone line in b, can I use call forwarding to transfer calls originating in a to my number in c. 2. If so, can I use a little box like the one sold by Hello Direct that allows user to change the call-forwarding destination number from another phone to achieve the following: I am in exchange "c"; I make local call to my other line in exchange "b" and program the call forwarding to my intended destination in exchange "a". I then call the number in "b" a second time and reach the number in "a" from ny phone in "c" without a toll call. 3. Is there an easier way to accomplish this? Thanks. -- Russell Shackelford School of Information and Computer Science Georgia Institute of Technology, Atlanta, GA, 30332 russ@prism.gatech.edu (404) 834-4759 [Moderator's Note: We have covered this territory before. Yes, you can do what you are suggesting. It is marginally legal, or within the tariff. Telco will advise you that is not what they had in mind when call forwarding was offered. And yes, there is an easier *and cheaper* way: Dial direct! It is very rare that the cost of two or three local calls strung together turn out to be less expensive than a single call to the place you are calling. If you have unmeasured local service in your community and in surrounding areas, you *might* be able to save money -- if not time and bother in dialing -- by stringing local points together. But if you have measured local service, as most of us do these days, you are kidding no one but yourself thinking that two or three measured, timed local calls will cost less in the end than the cost of the toll call itself. Besides which, you have to amortize the cost of the device you purchased. And after you have programmed it to forward the line, how do you regain control of the device itself on subsequent calls without going to the physical location and resetting it?

I have a slightly different problem. Two years ago Rochester Telephone installed an ESS (model unknown to me) and since then I've had a problem of hanging up and being able to place another call. If I should misdial and get an intercept message (ie That number is not in service), I try to hangup and get a dialtone and I can't. I keep hearing the message over and over again. Also if I call someone and the phone is ringing, but no one answers, I can't hangup. This doesn't happen all of the time but several times a week. I have to hang the phone up and wait, wait, wait (up to 20 minutes, most of the time 5 or 6 minutes). When the line does finally clear the bell on the phone "bings" once and I'm back in business. I've tried disconnecting all of my extensions (4 extensions, 1 answering machine) but this doesn't seem to have any effect. Any ideas what might be causing this? ------------------------------ Subject: CCITT R2 Signaling Scheme Date: Fri, 7 Jul 89 6:00:28 MEZ From: logex Hi all: I am located in Mexico City, and I am interested in getting more information about the CCITT R2 signaling system (phone, of course). As far as i know, it has 2400 and 2040 hz signaling tones, and it also has 6 reverse frecuencies: 540,660,780,900,1020 and 1140 hertz, and 6 forward direction frecuencies: 1380,1500,1620,1740,1860,and 1980. What I want / need to know is how this signaling scheme works, i.e., what is the matrix of digits and other tones and what is the purpose of each tone, such as the 'Key Pulse' and 'ST' in the USA signaling system? Thanks in advance for your help, and please email your responses to me, I will summarize to the net.

Note that a long distance call over 62 miles (100 km) is about 60 cents a minute, whereas we can call coast to coast for 25 cents a minute. The cellular charge includes the rate for a call to anywhere in Germany, so the marginal usage cost (except on local calls) is actually pretty close to U.S. rates. The landline rate must be set so high to discourage calling: it's quite hard to get a landline call through during peak hours. In the U.S. the grade of service in the public network is usually better than P.01 (one out of 100 call attempts will get a circuits busy rejection) and businesses usually engineer their private networks at P.05 or better (one in twenty fails). In Germany, I don't know what the busy hour design is, but it seems like it's around P.50 (one out of two calls will get a circuits busy). I've had to try ten times to get a landline call through from Stuttgart to Munich at the peak time in the mid afternoon.

Campbell, 7/7/89. Paraphrased except for items in quotes.] QUESTION: J. T. observes several one-minute call charges on his/her MCI phone bill. These were made to answering machines that answer on the fifth ring; he/she always hung up after the third or fourth ring. MCI first claims that J. T. would not have been charged if the machine hadn't answered. An MCI manager later informs the customer that "when [you] call a number with an answering machine -- no matter how soon [you] hang up -- [you] will be charged because the two machines have made a connection," and therefore no reimbursement can be made. The MCI manager also claimed that "all long- distance companies have the same problem because of this 'connection' over which they have no control." AT&T told J. T. that "they charge only when a person, or a machine, actually answered." But J. T.'s mother has AT&T and has the same problem. ANSWER: "Both answers [from MCI and AT&T] are perfectly valid. [...] Here's how it works: You call a number serviced by an answering machine. [...] About '2 to 3 seconds' *before* the ringing stops and the pause indicating that the machine is about to respond, there is a distinct *click* on the line. This is described by [a Panasonic technical person] as 'a plunger in the relay making contact with the cassette player.' And this is when the telephone company's meter starts running." [emphasis theirs] Campbell tested his own machine; it exhibited the click 12 seconds after the first ring had begun and continued ringing for 2 seconds after the click. He was charged for the call if he hung up after the click. " 'I think that a lot of people have this misunderstanding,' said [an AT&T spokesperson], 'that if they hang up while the phone is still ringing, the call hasn't gone through. Actually, the recording machine has been triggered at the instant that click takes place, but in many cases the caller is in the process of hanging up and doesn't have the phone at his ear, and so he doesn't hear the click.' " MCI confirms that it operates similarly. The MCI spokesperson points out that this is *not* the same as lack of call supervision, which caused "ring-no-answer" billing. "Just when the telephone answering machine kicks on isn't standardized [...] among the manufacturers." "There's one possible moral in all this: If your timing is off and you hear the click, you might just as well stay on the line long enough to announce yourself." "Because you've paid for it anyway." -- Kian-Tat Lim (ktl@wagvax.caltech.edu, KTL @ CITCHEM.BITNET, GEnie: K.LIM1) ------------------------------ Date: Sun, 9 Jul 89 6:44:56 CDT From: TELECOM Moderator Subject: Unusual Recorded Messages Talk about specialization.

Well, today, I was using a Pac Bell payphone which specified that all coin calls default to AT&T while credit card, collect, and other operator-assited calls default to US Sprint. COCOT owners can choose any LD carrier they want. What about the local telephone companies who own the majority of payphones -- are they free to choose carriers or do they have to give some share of the 0+ calls made from payphones to every LD carrier which provides operator services?

Now the Japanese are >going that way. I don't know about Japan, but the French decision to go to 8-digit codes is easy to understand. In French, you don't read single digits out, but you give them by two. Thus, the number 67.54.78.94 is read out "sixty-seven fifty-four sixty-eighteen eighty-fourteen". The norm was the 6-digit number, but when there were 7 digit numbers in Paris, this was unconfortable: the number 597.25.17 was read "five-hundred-eighty-seventeen twenty-five seventeen", which is not noticeably less work than the 8-digit example. Splitting off the 5 would tend to get it confused as a city code (especially by Belgians, whose city codes are that short). It was simply aesthetically pleasing to return to an even number of digits - it allowed people to talk about telephone numbers "normally" again. Even the French special numbers come in groups of 2 - information is 12 (I believe), long distance is 16, videotex is 36 15, etc. - only when you go international do you have to worry about lonely digits. I keep expecting to see telephones for the French market with 100 buttons on a 10 by 10 grid, but I guess you'd have to have some confusing feature for international service, so it probably wouldn't go over well. As far as the Bell study is concerned, I wasn't around at the time, but I'm sure that it had the single-digit American parochialism built-in. Who's to say how this influenced the results? I do agree that there should be more flexibility in number lengths. Germany is a good example - they have 3 digit area codes and up to 8 digit numbers for the big cities, and 5 digit area codes with down to 3 digit telephone numbers for the smallest towns, plus anything in between. More important numbers are often shorter than those of individual subscribers. As the town grows, they discretely hang single digits on the fronts of old numbers as needed, or some such thing. They will never run out of numbers (unlike the US). The inappropriate rigidity of the American 7-digit system is well demonstrated on one extreme by the relatively traumatic phenomenon of area code splitting in big cities, and on the other by a local radio ad I heard once passing through a small town in rural America: " . . . that's Mabry's Drugstore, First Street n' Depot Avenue, for all your prescription needs, call 582- hmm! (crash, boom, rustle, rustle) - 'scuse me whahl I look up the number - (shuffle shuffle) call 582-1478 for Mabry's Drugs. Movin' now to the obituaries . . .

Is this the editor? Me: Only if you don't have a complaint. Caller (chuckling indulgently): Oh, no. I'm with Flack's Unlimited Public Relations, and I'm calling to get your fax-machine number. Me: Why? Caller: Why, what? Me: Why do you want our fax number? Caller: Because I want to send you something. Me: Can't you just mail it? Caller: But we want this to really stand out. We know that editors get dozens of pieces of mail a day, and we want to make sure this gets to you. Me: I'm sorry, but we are not giving out our fax number. We've been having trouble with obscene phone calls. Caller: I beg your pardon? Me: People have been making obscene calls to our fax machine. I'm sorry, you sound like a perfectly nice person, but you never know. Caller: Who on earth would make an obscene call to a fax machine? Me: You'd be surprised. The last guy was some pervert from Australia. The tone reminded him of a wild dingo in heat. (alternate answer) Me: Sorry, but our fax machine is staging a wildcat strike. No matter what you send it, it prints out the collected speeches of Samuel Gompers. The truth is, of course, I say these things because we don't like giving out our fax number to people. I know faxes are supposed to be great, time- saving conveniences, and indeed, there have been times when I've been glad to have mine around. But more and more, our fax is getting clogged up with advertisements, press releases that are utterly unsuitable for our newspaper, and other junk. This annoys me even more than nuisance phone calls. At least with a phone call, you get to slam the receiver in the guy's ear. Others are beginning to notice this problem. There is a movement afoot to restrict junk fax messages. Connecticut recently passed a law subjecting senders of unsolicited fax messages to a $200 fine. The way the law came to be passed was this: When the Connecticut state legislature passed the measure, some business lobbyists made a last minute effort to persuade the governor not to sign it. They inudated his office with -- you guessed it -- fax messages, tying up his machine for more than two hours and preventing his staff from receiving a report they needed. The governor, infuriated, signed the bill into law immediatly. I say, hat's off to Connecticut. And I'd like to send him a letter, but it might get lost in the shuffle.

Steve Dahl and Garry Meier, disk-jockey hosts of a popular afternoon radio show on WLUP-AM (1000 kc) in Chicago now have a fax machine in their studio to accept comments and other items from listeners. In the past, the only way to get through to them was by managing to break through WLUP's jammed phone lines. But technology, like time, marches on, and radio audiences can now use fax machines to communicate with these two fellows and other radio personalities. The fax machine in their studio operates almost continually all day. Every few minutes, something new comes through. While some of it is usable on the air, much of it is unsavory, and best used for a private laugh in the studio, with only a brief (and cleaned up) mention on the air. One WLUP disk jockey is Rob Lowe. Someone sends a fax which has altered the spelling of his name with unwholesome results. The very next item to arrive is a lewd cartoon featuring a pig and a chicken. Rick Kaempfer, producer of Steve Dahl and Garry Meier's afternoon radio show said, "We get a lot of things that people are afraid to say themselves, but they fax it hoping that Steve or Gary will talk about it on their show. Frankly, much of it is so lewd there is no way we can clean it up well enough to use over the air. It is funny though." Kaempfer claims Dahl and Meier were the first to incorporate a fax machine into their on-air schtick, and they have been giving the fax number to listeners for at least a year. But according to Brian Kelly, program director at station WLS (890 kc), his station was the first to have an *in-studio* fax machine. WLS, like competitor WLUP, welcomes the frivilous, and the more-so the better. Both stations invite people to 'Fax your face' to the station, so the deejay's can describe you to the listeners. People are to make a copy of their face on the office copy machine, then fax the copy to the station. Kelly noted that "...faces are not the only body parts they fax to us. They actually put the naked part of the body on the copy machine, and then fax the results to us. We've gotten enough body parts to make a complete person, although we have a big overstock of certain parts. I guess they think it will shock us." WLS' midday deejay, Doug Blair, is by far the most fax-infested at that station because the vast majority of fax-ers work 9 AM to 5 PM, in offices where fax machines are available and the employees obviously are not kept busy enough and have idle time to create mischief. Indeed, the dawning of radio's fax era has updated, but hardly altered, the time-honored practice of goofing off at the office when your supervisor is not watching. In a less state-of-the-art era, the average employee pretended frantically to be calling a client when, in truth, he was hoping to be the lucky 'caller number ten' in the radio station's cash giveaway contest. Today, that same employee stands at the office fax machine, ostensibly sending a copy of that important report off to the client. After looking around furtively to make sure the supervisor is elsewhere, he in fact sends an obscene joke to Dahl and Meier, hoping they will read it over the radio, or else a copy of that picture he made on the copy machine the night before, after everyone had left the office but he '..stayed late to finish that urgent report...' ------------------------------ From: Kent Hauser Subject: AT&T Int'l Gateway Configuration Date: 9 Jul 89 19:42:05 GMT Organization: Twenty-First Designs, Wash, DC I am currently trying to devise a method of reconfiguring a network which is physically in the US but is connected to the AT&T International gateways in New York City and Sacramento. I'm having trouble getting technical info from AT&T and hoped some of you might know about AT&T's int'l system. Currently, the networks connect on the Int'l side of the AT&T gateways and use CCITT No. 5 signalling. This arrangement was fine when the inital connections were established since the switch and tranmission facilities were analog. However, now there are digital facilities connected directly with the gateways & we have a digital switch being procured. Unfortunately the new switch doesn't support No. 5 so the choice is to install a channel bank & signalling converters to convert from R1. This seems silly. The word from AT&T is that inbound they *use* KP1/KP2 to determine if a call is terminal or transit (I guess that's so they won't have to reprogram if country code `1' is reassigned :=). This of course is not standard R1, but hopefully we can hack this. The more troublesome problem is AT&T claims that outbound, there is no way to configure the gateways to generate R1 line signalling on the international side.. The only choices seem to be CCITT No 5, 6, and 7. (None of which are found on your basic toll switch.) This problem does not seem to be easily solved, unless of course the information is incorrect. This is what I am hoping. For what it's worth, there are multiple 3-digit country codes involved, and either 7 or 8 national digits. There is also an analogous problem with the connections to Teleglobe's gateways in Montreal & Vancouver, but we're not having so much trouble getting help solving them. Help/pointers/contacts/info appreciated. -- Kent Hauser {sun!sundc,uunet!cucstud}!tfd!kent Twenty-First Designs kent@tfd.uucp ------------------------------ From: Alaska's leading Cyberpunnk Subject: Re: Buggy lines Date: 9 Jul 89 09:41:52 GMT Organization: Computer Connection In article , claris!wet!epsilon @ames.arc.nasa.gov writes: > I have one of those GE multiline phones with the line-monitoring > LEDs; each day around 0200 (the exact time varies) they flicker > briefly.

He told me he unhooked it to check the line, because the "computer said you had some trouble out here"... seems the little tortured-cricket ringer doesn't couple to the line the same way a coil does, and it makes your phonne pair appear unterminated _and_ of uneven length(!?)

(415-337) Counting RENs? :-) They flicker because the telco is testing the loop (Your line to the Central Office). The lights should not flicker if the phone actually met FCC Part 68 and Bell Pub 48005 and the GTE equiv the number of which escapes me right now. The phone when On Hook should have a DC resistance above 10 Meg Ohm and a particular on hook impedance. Exact numbers escape me, but without getting too techie let me explain what is expected. A phone on hook should present a 0.47 uf Capacitor and a large coil of wire in series to the loop. This means a gong ringer and the DC blocking capacitor. Most ringer ICs (the ones that chirp and warble) do not present this impedance curve to the phone line. The Motorola ones do and I think the AT&T ones may. No one ever gave me AT&T phone ICs to play with. Now the lights on the GE phone are possibly controlled by Zener diodes that turn on the lights when the DC voltage drops below say 26 Volts. The normal on hook voltage is 48 V and off hook it will drop to about 9 to 3 V. When testing the telco may lower the line voltage and your lights may flicker. They also sometimes use low frequency and low voltage test sigs. Maybe someone at the CO side of biz could supply us these specs? The Telco would probably love you if you junked the phone and got a real one so they could get meaningful test results.

If you put one of their diallers by the protector, every phone in the house can use the same dialler which is controlled by the Touch Tone pad or Hook Switch flashes. Plus it comes with a supercap that keeps the memory alive for 7 hours if there is a power outage. Not only can any phone in the house dial via a short sequence, you can store numbers that are dialled via built in account codes i.e. selected common carriers or phone credit card numbers that can be accessed during a call. Plus it will "Demon Dial", redial a busy number. Great for calling houses with teenagers. And yes, you can store over 100 numbers in a Demon Dialer.

This tone is supplied by the central office at the called end and tells you that your call was successful and that the party's phone is ringing (as opposed to not going through or busy). When the called party answers, ringback tone ceases immediately and the connection "supervises", or in older parlance, "reverses". For the majority of carriers that handle supervision, this is when the clock starts. It makes no difference whether a machine answers or a person answers, one thing is certain: ringback tone ending and supervision beginning are a simultaneous event. If the machine answers on the fifth ring, that's when billing begins and not before. > An MCI manager later informs the customer that "when [you] call a > number with an answering machine -- no matter how soon [you] hang up -- [you] > will be charged because the two machines have made a connection; therefore > no reimbursement can be made. The MCI manager also claimed that "all long- > distance companies have the same problem because of this 'connection' over > which they have no control." Garbage! No long distance company can tell whether an answering machine or a person answers the phone, especially before they've answered it! My answering maching has this "cheap realtor" mode and I have *NEVER* been charged for a call when I hung up before the [CLUNK]"Hello....". Sounds like MCI just doesn't want to deal with THEIR problem and particularly doesn't want to refund any money. > AT&T told J.

If it really answers, then yes. If not, get your money back. Actually, I had a discussion of this matter with someone at Pac*Bell. Ms. PB said that by all rights, a subscriber should be charged for a call made to an answering machine that answers after many rings when it has no messages for its owner. Reason: information has been passed (that the machine has no messages). I countered with the fact that while the owner now knows that there are no messages, no "communication" has occurred. It's the same as a busy or no-answer: the caller knows that the party is on the phone or isn't home. That's information but not communication. Oh, well.

Subscribers >will add a 3 at the beginning of their seven digit numbers. >What am I missing here? What's wrong with a "downtown" city code and a >"suburb" city code? If a country doesn't need a full up 3 digit area code, I did not see the article in the paper, but I have double checked with a friend in Tokyo via e-mail before sending this mail. First off, it should be noted that area codes in Japan like many other countries vary with where you are calling. Thus, the *area code* for Tokyo is currently 03, but the area code for Mitaka just to the west of Tokyo is 0422. I am sure that some cities have two digit area codes, but I cannot name them with certainty off the top of my head. [ BTW, the leading zero is not a typo; in Japan a single leading zero indicates a long distance number; a separate number is dialed to get an operator.] As another poster pointed out, the 03 area code is only used for "central Tokyo", not the entire metropolitan area. Thus, there are many area codes in the suburban area. I don't know how many area codes are within a 60 minute or 90 minute commute from central Tokyo although many if not all of the numbers are only 6 digit numbers. I would guess there are possibly up to 100 area codes surrounding Tokyo. (Some of these are however, presumably currently unsigned). My source indicates that the 03 area code will be broken into smaller area codes, Tokyo will not go to eight digit numbers. If you think about it, however, the difference can be merely semantic. Thus, it seems that all current Tokyo area codes will change from 03 to 033. Whether the relatively small geographic area of Tokyo will be subdivided or not is in may respects irrelevant. It may be different from U.S practice, but that does not make it bad or good; the answer to that implicit question depends on how the change is implemented. [For example, I live in area code 213 in the city of Los Angeles; if you were to call information (at least from LA) and ask for David Gast in LA, you would be told that I do not exist because the teleco thinks I live in *West* Los Angeles even though the PO says I live in Los Angeles, CA 90025. That is, if directory assistance can handle all Tokyo numbers (03x), not subdividing a small geographical area might be preferable to the LA situation where GTE/PacBell cannot even handle one area code properly. I do not, however, know what will happen to the central Tokyo area code except that it will become 2 digits instead of one. (Even though I live in LA, I do not propose to know the exact demarcation line between 213 and 818 in LA).] BTW, if you think about it, merely adding a 3 to the beginning of all numbers does not add any numbers to those possible to dial. David Gast gast@cs.ucla.edu {uunet,ucbvax,rutgers}!{ucla-cs,cs.ucla.edu}!gast P.S. Nippon tends to be a rather conservative and militaristic reading for the characters which can also be read *Nihon*. As I recall, the official name of this telephone company is NTT. If you suspected that the two T correspond to English words and not Japanese words, you are correct. The Japanese names for the two T's are Denwa Denshin (Telephone Telegraph). [Moderator's Note: An example of the complete opposite of the 213/818 situation described by Mr. Gast is in metropolitan Kansas City, MO/KS. An inquiry can be directed to either 816-555-1212 or 913-555-1212 with equal results. Call either one; get information on either side of the river.

(But they won't share their sources(s) with me... sigh.) Are you sure they don't just get detailed billing tapes back from your CO operator? Anyway, this information comes from FCC tariff number 5. This at least contains intra and inter lata/state (yes there is such a thing as intra-lata inter state calls) mileage bands for (last I checked) ATT, MCI and Sprint. I don't recall seeing things like the reach-out-America plan in there, but then again I wasn't looking for that. To calculate the mileage bands you need a V&H tape. Both of these are available from Bellcore, at no small cost. Oh, you also need software to drive these, taking things like rate corridors, taxes, discount periods, volume discounts, etc into account.

Is it purely a matter of personal taste, or >can you suggest reasons why providing it for yourself might be preferable >to that version sold by the telco and maintained in the CO? > My response to this question is that the personally owned equipment beats the CO maintained system far and away on price and convenience. In Maryland (C&P country), the charge for 8 number speed calling is $1.50 per month and $4.00 per month for a 30 number list. Approximately 30 months ago, I purchased a 40 number memory feature phone for $80.00 (LCD Display, speaker, hold, redial, etc.). Thus, on speed dialing alone, I've already saved $40.00. The convenience aspect comes into play when it's time to dial one of these numbers. My phone has 20 buttons and a shift button, so no number requires more than two keystrokes to dial. To dial from a regular Touch-Tone phone to a CO maintained list requires that you 1)Remember a CODE for the number you want to dial and 2)Press a three key sequence (two if you don't press '#' and are willing to wait..). Oh yeah, programming the feature phone is easier, too. Just in case you're wondering, I did have the CO maintained speed calling way back when. I just decided, for the reasons outlined above that it was more worthwhile to buy a feature phone (my decision was aided by the premature death of my standard desk phone at the hands of my cat). --John DiLeo-Lopez dileo@amsaa-seer.brl.mil ------------------------------ From: Joel B Levin Subject: Re: Speed Dialing: CO vrs. Premises Equipment Date: 6 Jul 89 13:25:20 GMT Reply-To: Joel B Levin Organization: BBN Communications Corporation I use CO speed dialling for two reasons: (a) I have two extensions at present, both vanilla. Speed dialling works from both. (b) If I had two phones with speed dialling I would have to be careful to keep the programming identical in both (required by the nature of the users around the house). Of course, the on-premises solution which would satisfy these is a separate box on the line to do the speed-dialling. I have never looked into the cost of this option. Steve Elias mentioned the rapidity. I hadn't thought of that; but it's true. When I speed-dial a number on one of the local ESS exchanges, the call is placed _instantly_ (e.g., if it is busy, I get the signal with no delay after keying #). This is not one of the reasons I have it, though. /JBL UUCP: levin@bbn.com (new) or {backbone}!bbn!levin (old) INTERNET: levin@bbn.com POTS: (617) 873-3463 "Earn more sessions by sleeving." ------------------------------ Date: Mon, 10 Jul 89 10:48 EDT From: "Scott D.

The codes seem to be allocated according to which part of the world the country is located in with the first digit of the country code indicating the region, though as always there are exceptions (codes 297-299). Harking back to a few digests ago, I think it would be wise for CCITT (I think that's the correct regulatory body) to split country code 1 so that Canada and the Carribean Islands have their own codes (e.g. USA = 11, Canada = 12, Islands = 1[3-9]X). I know there would be some hassle in going through with such a major change, but it will have to happen some day. It is the only major country code that is split between independent nations. +--------------------------------------------+--------------------------------+ | K.Hopkins%cs.nott.ac.uk@nsfnet-relay.ac.uk | Kevin Hopkins, | | or ..!mcvax!ukc!nott-cs!K.Hopkins | Department of Computer Science,| | or in the UK: K.Hopkins@uk.ac.nott.cs | University of Nottingham, | | CHAT-LINE: +44 602 484848 x 3815 | Nottingham, ENGLAND, NG7 2RD | +--------------------------------------------+--------------------------------+ -----------------------------------CUT--HERE----------------------------------- 1 North America and the Carribean Also code 297 2 Africa Except for codes 297-299 3 Europe Also codes 298 and 299 4 Europe 5 Central and South America 6 Indochina and Australasia 7 USSR 8 East Asia 9 West and Central Asia -----------------------------------CUT--HERE----------------------------------- (Split on columns 1, 37 and 49 if necessary) Algeria 213 Andorra 33 628 Sub-country code of France Angola 244 Anguilla 1 809 407 Antigua & Barbuda 1 809 Antilles (Netherlands) 599 Argentina 54 Aruba 297 Ascension Islands 247 Australia 61 Austria 43 Azores 351 Bahamas 1 809 Bahrain 973 Bangladesh 880 Barbados 1 809 Belgium 32 Belize 501 Benin 229 Bequia 1 809 45 Bermuda 1 809 23 Numbers starting 4,6 or 8 Bermuda 1 809 29 Numbers starting 2,3,5 or 7 Bolivia 591 Botswana 267 Brazil 55 Brunei Darussalam 673 Bulgaria 359 Burkina Faso 226 Burma 95 Burundi 257 Cameroon 237 Canada 1 Canary Islands 34 Cayman Islands 1 809 94 Central African Republic 236 Chile 56 China 86 Christmas Island 672 Cocos (Keeling) Islands 672 Colombia 57 Congo 242 Cook Islands 682 Costa Rica 506 Cote d'Ivoire, La 225 Cuba 53 Cyprus 357 Czechoslovakia 42 Denmark 45 Djibouti 253 Dominica 1 809 44 5 figure numbers Dominica 1 809 449 4 figure numbers Dominican Republic 1 809 Ecuador 593 Egypt 20 El Salvador 503 Ethiopia 251 Falkland Islands 500 Faroe Islands 298 Fiji 679 Finland 358 France 33 French Guiana 594 French Polynesia 689 Gabon 241 Gambia 220 German Democratic Republic (East) 37 Germany, Federal Republic of (West) 49 Ghana 233 Gilbraltar 350 Greece 30 Greenland 299 Grenada (including Carriacou) 1 809 440 Numbers starting 1,2,3,7 or 9 Grenada (including Carriacou) 1 809 443 Numbers starting 5 Grenada (including Carriacou) 1 809 444 Numbers starting 4,6 or 8 Guadeloupe 590 Guam 671 Guatemala 502 Guyana 592 Haiti 509 Honduras 504 Hong Kong 852 Hungary 36 Iceland 354 India 91 Indonesia 62 Iran 98 Iraq 964 Irish Republic 353 Israel 972 Italy 39 Ivory Coast 225 See Cote d'Ivoire, La Jamaica 1 809 Japan 81 Jordan 962 Kenya 254 Kiribati 686 Korean, Republic of (South) 82 Kuwait 965 Lebanon 961 Lesotho 266 Liberia 231 Libya 218 Liechtenstein 41 75 Sub-country code of Switzerland Luxembourg 352 Macao 853 Madagascar 261 Madeira 351 91 Sub-country code of Portugal Malawi 265 Malaysia 60 Maldives 960 Mali 223 Malta 356 Marshall Islands 692 Martinique 596 Mauritania 222 Mauritius 230 Mexico 52 Micronesia 691 Monaco 33 93 Sub-country code of France Montseratt 1 809 491 Morocco 212 Mozambique 258 Namibia 264 Nauru 674 Nepal 977 Netherlands 31 Nevis 1 809 469 New Caledonia 687 New Zealand 64 Nicaragua 505 Niger 227 Nigeria 234 Norfolk Island 672 North Mariana Islands 670 Norway 47 Oman 968 Pakistan 92 Panama 507 Papua New Guinea 675 Paraguay 595 Peru 51 Phillippines 63 Poland 48 Portugal 351 Puerto Rico 1 809 Qatar 974 Reunion 262 Romania 40 Rwanda 250 Saipan 670 See North Mariana Islands Samoa (US) 684 Samoa (Western) 685 San Marino 39 549 Sub-country code of Italy Saudi Arabia 966 Senegal 221 Seychelles 248 Sierra Leone 232 Singapore 65 Solomon Islands 677 Somalia 252 South Africa 27 Spain (including Balearic Islands) 34 Sri Lanka 94 St. Christopher 1 809 465 Also known as St. Kitts St. Kitts 1 809 465 See St. Christopher St. Lucia 1 809 45 St. Pierre & Miquelon 508 St. Vincent and the Grenadines 1 809 45 Sudan 249 Surinam 597 Swaziland 268 Sweden 46 Switzerland 41 Syria 963 Taiwan 886 Tanzania 255 Thailand 66 Togo 228 Tonga 676 Trinidad and Tobago 1 809 Tunisia 216 Turkey 90 Turks and Caicos Islands 1 809 946 USSR 7 Uganda 256 United Arab Emirates 971 United Kingdom 44 United States 1 Uruguay 598 Vanuatu 678 Vatican City 39 66982 Sub-country code of Italy Venezuela 58 Virgin Islands (UK) 1 809 49 Virgin Islands (USA) 1 809 Yemen Arab Republic 967 Yemen People's Democratic Republic 969 Yugoslavia 38 Zaire 243 Zambia 260 Zimbabwe 263 -----------------------------------CUT--HERE----------------------------------- ------------------------------ From: "John R.

Bernholdt" Organization: University of Florida Quantum Theory Project While traveling recently in Louisville, Kentucky I needed to make a local phone call from a pay phone, first getting the number from a directory. The COCOT I stopped at first demanded $0.50 to be connected to 411. So I moved on to a South Central Bell payphone I saw a couple of blocks away. They wanted $0.25 to reach 411. (Neither had phonebooks). I spoke to the '0' operator and her supervisor, explaining to both that there were no phonebooks in the booth & that as a consequence I needed to get the number from 411. I was told by both people that their instructions are to ASSUME THAT THE CUSTOMER IS LYING and charge for the call regardless. Their theory is that since So. Cent. Bell once placed phone books there, they will always be there and anyone who stand there in the booth & claim they aren't there is a liar. They offered to connect me to 411 at a charge of $0.55 (it would be operator assisted). I found both of the people I talked to rather rude, and the entire idea of charging for 411 when there are no phonebooks available is (to me) ludicrous. I there anything I could/should have done at the time to complain about this in a way that might make any kind of difference? (I am assuming that it is too late to accomplish anything now.) I also wonder how common this is (charging for 411, not the rudeness)? -- David Bernholdt bernhold@qtp.ufl.edu Quantum Theory Project bernhold@ufpine.bitnet University of Florida Gainesville, FL 32611 904/392 6365 ------------------------------ From: Mike Morris Subject: Demon Dialers (was: Speed Dialing) Date: 11 Jul 89 05:59:30 GMT Reply-To: Mike Morris julian@bongo.uucp (julian macassey) writes: >(D.

The concept is great, but the execution leaves a little to be desired. There is no true touchtone decoder- the custom Rockwell chip uses a zero-crossing detector and sone firmware. There is no way to read out the data, or to clone the data into a second unit for a second line (if my wife is on line 1, I have to grab the phone book and _look up_ (gasp) the number and use line 2). The last-number-dialed memory gets zapped by an incoming call (ring voltage?). The transformer (wall-plug-power-cube) is buzzy - we had to move the device into the basement as it kept my wife away when it was behind the curtain in the living room, adjcent to the bedroom (we have a quiet house). At the office, wiring the unit into the 1A2 keyphone was a grade AAA bitch. All in all, it's the only game in town for the tricks it does. But if somebody made one with a Mitel 8870 chip, and a bit better design, I'd toss the three I have in a minute. Maybe the next version will have a RS-232 port, and some firmware that will talk to a printing terminal. US Snail: Mike Morris UUCP: Morris@Jade.JPL.NASA.gov P.O.

My computer and the modem itself (external) were turned off, but still connected to the phone line and the electrical outlet. I was home at the time and after a very close (or at least LOUD) bolt all of the lights on my modem came on, my telephone answering machine went off (started playing the announcement message) and all of the LEDS on my GTE memory phone lit up. I knew immediately that this was going to be expensive. The answering machine survived the ordeal without damage. The telephone survived okay but I had to remove all of the batteries to get the lights to go back off. The modem was killed as were two chips in my computers RS232c card. I lost telephone service (no dial tone) for about 15 minutes, it came back all by itself (how I know this in a second...) Now I'm almost a complete novice when it comes to the telephone network but I assumed that somewhere along the line there should have been arrestor to stop this spike before it reached my line. (I wonder if I would have been shocked had I been on the phone at the time?!?) I went to the telco to complain...(Contel) (yes, I went in person) and spoke with a lower level managment person. I had a hell of time convincing him that the spike had come over the phone line...and not the power line (he wanted me to take my complaint to Commonwealth Edison). Finally he checked the tarrifs and decieded that if a fault could be found in the spike arrestors at my sight then the Telco would discuss paying the damages. He really doubted that the spike even came over the phone line because the protection "fuses" would have blown and stayed blown...requiring physical replacement. Since my service was working, and there hadn't been any repairs (thus it fixed itself) the fuses hadn't blown. I have no proof that the spike did come from the phone line...other than the fact that only phone equipment went bonkers. And the phone was dead for a short time. Anyway..to bring this long story to an end he sent out a repairman who checked my line to see if it met "specs" (it did) and I ended up buying a new modem myself. I don't harbor any ill feelings or regrets but wonder what those of you who are more familar with the system would have to say. -=->G<-=- PS: Yes, I now have a phone line surge protector, an rs232 surge protector, and loss/damage insurance on my PC. :) ------------------------------ From: chipcom.com!eli@eecs.nwu.edu Subject: Call Forwarding to Bypass Tariffs Date: Mon, 10 Jul 89 08:22:19 -0400 Regarding Patrick's comments about call forwarding... in particular that it is not cheaper to pay for two local hops than the one toll hop...

I'm about to move into housing built by my employer, who owns the switch that my phone service will be on. According to everyone I've asked, I will not have a choice of long distance carrier. Access codes won't work (I'll get a busy signal after dialing 1-0, just like I do now from my work phone), and the local company (NJ Bell) says they can't install a phone for me. I'll be renting, but some of the housing units will be sold, and the buyers are in the same situation. Now it's not such a bad deal - free basic service and local calls (a smaller "local" area than NJ Bell), but long distance calls are carried by MCI, and I would do better with AT&T (I subscribe to Reach Out, America and use USprint for nearby calls when the AT&T flat rate is in effect). Maybe MCI has some options like Reach Out, America, but they aren't available to me. What's the legality of all this? Can I get a calling card from anyone at all? Can I use an 800 number for any of my long distance calls, bypassing MCI?

I just recently saw some interesting information on the subject of war-dialers and phone "hackers".... Supposedly there are people who use their personal computers to "hack" out 950-XXXX or 800 LD phone services.... I was just curious as to the reality of this and also the circumstances involved in doing such a thing (I'm sure you'd get into a LOT of trouble, no doubt!)... More importantly, what have the LD phone companies been doing on this matter? It seems that a while back someone had "hacked" my LD calling card. No doubt I was upset, but what can the phone company do to prevent such a thing? With all the info here on ESS and other sophisticated systems, do these devices provide "anti-hacking" routines?? I heard that many LD companies have a device called ANI? What is this? Also I heard that the rapid dialing of digits by wardialers also set off a "suspicious" activity flag.. Is this true?? I am new to this net and any information would be appreciated... It's quite interesting to see how the phone co really works when you make an ordinary call...

I would guess that the switch detected the trouble and automatically ran some diagnostic program to find out what was wrong with the line.

We used to have one locally called "Dial A Poet", but it disappeared from the directory a couple years ago. One of my friends called it once, and said it was really depressing. This leads me to wonder whether maybe it changed to "Dial A Sober Thought", which IS in our directory [(518)456-3492]. We also have "Dial A Bird" [(518)439-8080], which has been around for several years. One time we left a phone message for a particularly stuffy co-worker, and wrote down the "Dial A Bird" number. This person was very officious, and, as it happened, had a visitor with him when he came back to his desk and found the message. "Oh, excuse me, I have to return this call", he said, like he was expecting it to be someone asking for his help in ending the Cold War.

A user on one CO calls a distant CO; the supervisory signals to pass the destination and billing info are passed thru each switch along the path and then the end user terminal is rung. When the set is answered the CO sends the supervisory signals back to the originating CO along the same path they took to get there. Propagation delay is as much as 10 seconds I am told (this would not be typical). If the originator gave up before (real time) the destination answered the near CO would begin to send the necessary supervision signals toward the end CO. There is a window here where the path is reserved but no thru connection was ever achieved, this should not be billable. I should mention that with SS#7 (which MCI has in place) this should be changed for the better.

So, you might be counting the rings, and hang up on the third, while the answering machine has heard 4, and has started to answer.

I called customer service and was told that they happened because "the computer" thought the call had gone through. When I explained that I NEVER make one minute phone calls (doubt that many do...) They made the adjustment. I was told (no fooling) that the computer can get confused when it hears a noise on the line...it makes "the computer" think the call was connected. The rep suggested that (don't laugh) I may have coughed to the phone and confused the billing system. -=->G<-=- ------------------------------ From: John Wheeler Subject: Re: Will This Work and is it Legal?

PT] ---------------------------------------------------------------------- Date: Wed, 12 Jul 89 13:00:37 EDT From: jsol@bu-it.bu.edu Subject: Local Calling in Various Cities Boston has several plans: 1) measured service. each call is measured, including local calls. Only available as the only type of service in your home (you can't get measured and unmeasured service in the same house). 2) unmeasured: you get a small (?) local calling area. everything else is either measured or toll. cost is in between measured and metropolitan 3) metropolitan: entire boston region (most of 617) is local and included in the service. There are really 3 tiers to metropolitan service. The outer regions of the metro area have a larger calling area (for instance, Stoneham, MA (617-438) can call Lynnfield (617-334) but Somerville (617-623) can't for free. Places outside the metro area (like Framingham, 508-879) can opt for metro service and place most 1-617-XXX-XXXX calls free. I live in Somerville, but with a Cambridge phone number. Cambridge has the best unlimited local calling service for my calling pattern. I don't have metropolitan service, however I do make a few out-of-local calls and pay the message units to the phone company. Not enough revenue to warrant switching to metro service tho. Oh, there is also suburban service. That's metro minus the Boston Central Exchange (which is where most calls go). If you never call Boston Central, you might find this a useful feature. Then there's Hartford, CT. They are expanding their already huge local calling area in leaps and bounds. Hartford can call all of its suburbs, including some other cities (New Britain just became a local call). I think it's part of their desire to make businesses in other areas flourish by making them a local call to the Hartford market (or the other way around, make the Hartford market better by allowing people from, say, Canton (203-693) able to call Downtown). Hartford has the largest local calling area *by* *far* than any other place in the state. New Haven is starting to play the same sort of game, but they have a long way to go to make something as good as Hartford has. SNET has 3 plans now for local calls. Flat rate (most expensive), Measured rate (next cheapest) and Select-a-call. Select-a-call breaks it down like Boston's LCA so that calls to the same exchange (Newington to Newington) are 1c/minute, calls to Hartford are 2c and calls to say Rockville (203-872) (on the other side of Hartford, about 20 or so miles away) are 3c. I did extensive research on calling areas in NYC, parts of New Jersey, and Los Angeles. If there is enough desire to hear about them, I will post them too. --jsol [Moderator's Note: Jon Solomon, aka 'jsol' was founder of TELECOM Digest, and Moderator for several years. Yes indeed, please Jon, post another message or two, summarizing the local plans for the cities you've been in. I'll do Chicago, and readers are invited to summarize the local calling scheme in their own community. PT] ------------------------------ From: Chris Graham Subject: Help Needed With HST problems Date: Tue, 11 Jul 89 20:28:25 EDT Organization: Ziebmef Public Access Unix, Toronto, Canada I have a FidoNet number (1:250/716) and I poll various FidoNet systems to exchange packets. That much is normal. The problem is that I can't send packets to sites that are using the 14.4k HST modem. On the other end, the problem manifests itself as repeated CRC errors and my end keeps getting NAKed until it times out and hangs up in disgust. The problem is even worse now because my hub has been changed so that I must poll a system that has one of these modems and if the problem isn't fixed then I'll have to get a new modem, change my FidoNet number or leave the FidoNet altogether. I've spoken to a number of sysops and they all feel that it's modem incompatibility but nobody knows exactly what it is. The strange thing is that I can dial these BBSs interactively and xModem tons of stuff with no problems. If anyone can send me an explanation of what the problem is, and even how to fix it, I would be very grateful. And I have another problem with SEAdog 4.50. The problem is that there is a site that uses it from which I can't receive any mail packets that are waiting for my system for most of the day. I'm told that that version of SEAdog has a bug that precludes the pickup of mail during a crash-mail event. If anyone can send an explanation or solution to that, it would be a great service. ------------------------------ Date: Wed, 12 Jul 89 20:46:08 CDT From: TELECOM Moderator Subject: The Importance to *You* of "auto reply" Take a look at the information which appears immediatly below -- => Message sent to: telecom@eecs.nwu.edu => Dated: Wed, 12 Jul 89 21:42:19 EDT => Subject: "Whatever Title Was On Your Message Here" => Received by Telecom Moderator: Wed Jul 12 20:46:07 CDT 1989 => Message size: 442 bytes >This is an automatic reply from TELECOM Digest. Your recent correspondence >was received here per the information shown above. Because the volume of >mail received is frequently quite heavy, this computer generated response >is used to speed a reply to you. It is not intended to lessen the value >of your correspondence....... (and the reply goes on....I will stop here for now) The above is a letter very familiar to those of you who have written to TELECOM Digest or comp.dcom.telecom with a submission for publication, or to request addition/deletion/changes to the mailing list. If you have not written to me **or if you have, but have not received the above letter**, then what I say now will be of particular importance: Sad story: One regular reader in the Chicago area recently sent items for publication. He spent his time and effort preparing these articles to share with us. *All four got lost in transit*....swallowed by a black hole somewhere. It made me upset to have to report to him that not a single one of his submissions made it through the network, and he felt badly also. But he was tipped off that something was wrong when he did not receive the "auto reply" message sent out each time mail hits my box at eecs.nwu.edu. He was alert and contacted me to ask 'if auto reply is no longer being used'. "Auto.reply" is a program in my directory which kicks in each time mail is received. Other than a list of exceptions, such as 'mailer.daemon' and a few others known to themselves be automated responses, everyone who writes the Digest gets back the above receipt, and the form letter attached to it. This is intended to quickly inform you if your letter was somehow lost; and at the same time, it protects me against claims that perhaps some messages are deliberatly ignored while claiming non-reciept. It is intended as your proof that your letter was received here. Likewise, if you get two or more copies of the receipt, based on the same message, then you are alerted to the fact that somehow your message was inadvertently duplicated in the process of its transmission. I think all Moderators (and other users who receive heavy mail) should use "auto.reply", or something similar to assure their readers/correspondents that mail was received, or alert them when it was not received. I use "auto.reply" as a way of showing my concern for the hard work *you readers* do in writing the articles which have made TELECOM Digest a success. Always watch for "auto-reply" after you write me. If you don't get it in several hours -- maybe a day at most -- then send a duplicate of your correspondence. And always save a copy of what you have written until you actually see it in the Digest. Sometimes I get things, but still manage to lose them or mangle them in emacs. Also, please note that *sometimes* "auto-reply" itself fails to address you correctly, and *I* get it back undeliverable. Nothing is perfect! :) It has been written to attempt to get your correct address from the letter you send me. As we all know, those can get hysterical at times! :) Patrick Townson ------------------------------ From: Kenneth_R_Jongsma@cup.portal.com Subject: My Experience Using the Automated Operator Date: Mon, 10-Jul-89 10:12:20 PDT I've had a chance to make a call using Michigan Bell's new automated operator.

I'm wondering about how payphones work. It seems as if there are three main types: old fortress phones, that require a coin before you can do anything. The coin "opens" the phone for you. These seem to be connected to payphone-type central office pairs. New fortress phones also seem to have special pairs (or are there four wires?) that run to the CO, but don't require a coin first. And COCOTS seem to have more regular lines, with a lot more equipment in the phone itself. What's on those two/four wires for fortress phones? How do they work? -- # Daniel M.

Date: 12 Jul 89 13:37:38 GMT Organization: Rutgers - The Police State of New Jersey I know for a fact that MCI does NOT require that they be your home default carrier. In fact, they will give you a card with appropriate credit references if you don't have a phone. In addition, they have been very good to me about allowing my MCI card account to carry over the summer, after my school phone is disconnected in May. (I end up in a different dorm room each year, which means a new phone number every year.) I just call before I disconnect, and they take the residential service off of the account, but leave the card active with the same number. Then, after calling NJ Bell to establish the new number in August, I call MCI, close the old account the day before Labor Day, and request a new account with a new card.

Anything billed as a "lightening arrestor" as are the things at the entrance to your house for the phone lines, are there to avoid fires from lighting strikes. They don't operate anywhere near quickly enough to stop electronic equipment from being damaged. Likewise most of the "surge suppressors" on the market are just MOV's, and while these have use on AC power lines, if that's all they used in your telephone surge supressors (likely) it's not adequate either. -Ron ------------------------------ From: Ron Natalie Subject: Re: While Phone Rings, Charges May Begin [from LA Times] Date: 12 Jul 89 15:00:06 GMT Organization: Rutgers Univ., New Brunswick, N.J.

It is, however, missing the following assigned codes, possibly because they are not dialable by United Kingdom subscribers. Those indicated with an "*" are dialable from the U.S. by AT&T, and Mayotte is dialable by U.S. Sprint. 224 * Guinea 688 Tuvalu (Ellice Islands) 235 Chad 690 Tokelan 238 * Cape Verde 84 Viet Nam 239 Sao Tome and Principe 850 Democratic People's Republic of Korea 240 Equatorial Guinea 855 Khmer Republic 245 Guinea-Bissau 856 Laos 246 Diego Garcia 871 Marisat, Atlantic Ocean 269 x Comoros and Mayotte 872 Marisat, Pacific Ocean 355 Albania 873 Marisat, Indian Ocean 680 Palau 93 Afghanistan 681 Wallis and Futuna 976 Mongolia 683 Niue In addition, two minor typographical errors were found: Numbers on Anguilla are in NXX 497, not 407, and there is only one Ascension Island. I would caution against putting too much emphasis on the NXXs in area code 809; a concerted effort is under way to get seven digit dialing in place on all islands. New codes are being assigned which don't fit into the previous single code per island. For example, St. Kitts now also has 467 numbers. Attached I am reposting the entire numerical country code list from CCITT E.163 (with additions such as Taiwan, which lost 86 to the PRC several years ago and was ex-officio assigned 886). It won't include such things as Madeira and the Canary Islands for the same reason it doesn't include Hawaii or the Channel Islands. Don't hold your breath waiting for the North American Integrated Numbering Area to be split into multiple country codes. The community of interest is too strong to require dialling four additional digits on calls between the possible portions. It is more likely that Puerto Rico and the U.S. Virgin Islands would get their own area code, leaving more of 809 available for the rest. -------------------------------------------------------------------------------- World Numbering Zone 1 (Integrated Numbering Area) 1 Canada, USA including Puerto Rico and the Virgin Islands, Jamaica, Barbados, Anguilla, Antigua and Barbuda, Cayman Islands, British Virgin Islands, Bermuda, Bahamas, Dominica, Dominican Republic, Grenada, Montserrat, St. Christopher and Nevis, St. Lucia, St. Vincent and the Grenadines (Bequia, Mustique, Prune (Palm) Island, Union Island), Trinidad and Tobago Note: Mexico locations with Zone 1 style area codes are a hack for use from the U.S. and Canada *only* and are not official.

Reid" Subject: Pay Phone TDD Dear Telecom Readers: I found this article to be of interest and I thought you'd be interested to learn about new technology development for the hearing impaired. The following article is quoted from a newsletter for members of the Telecommunications for the Deaf, Inc. (TDI), a non-profit organization dedicated to improving the telecommunications for the hearing impaired, "GA-SK Newsletter", vol. 20, no. 1, Spring, 1989, page 18: PAY PHONE TDD UPDATE Cindy E. Hanson If you happen to be near Terminal Two in Chicago's O'Hare Airport and need to make a TDD call, just look for the "TDD Equipped" sign next to the information desk. The first Pay Phone TDD is now installed and ready for use. For the first time ever, the Pay Phone TDD allows people to have access to a TDD equipmed pay telephone. The Ultratec-developed Pay Phone TDD, which is located next to the information desk in Terminal Two, is well marked with a large "TDD Equipped" sign above it. O'Hare Airport was chosen as the first Pay Phone TDD installation site because of its high traffic. It's also only a short distance from Ultratec's corporate headquarters in Madison, Wisconsin, which makes it convenient for frequent testing and evaluations. According to O'Hare Airport's Susan Mally, Coordinator of Airport Information, the Pay Phone TDD is much better equipped for public use than the previous standard TDD. "There is no comparison" she says, "The Pay Phone TDD is very self-sufficient. We haven't had any problems." Prior to the Pay Phone TDD, the only TDD available in the Airport repeated showed signs of wear and tear because it was not enclosed or designed for public use. The Pay Phone TDD is attached to the bottom of a regular pay telephone, housed inside a vandal-proof metal drawer which opens only when a TDD number is dialed and a TDD signal is returned. Because of this design, the Pay Phone TDD does not show any signs of vandalism or misuse. While testing continues at O'Hare Airport, other locations including universities, schools, and public buildings are being researched as possible Pay Phone TDD locations.

It depended on the way that NY Telephone processed local calls preceded by your own area code; evidently, they went through some other path than calls dialed with 7 digits. If I dialed my own area code followed by my own number (i.e, 212-929-0110), I'd hear both a ringback tone, and a call-waiting tone to tell me "another" call was coming in. I'd then hang up, and the phone would ring once. Obviously, I had to have call-waiting to make this possible; it may also have depended on my having three-way calling. Without three-way calling, I suspect the call would've been killed quickly after I hung up. With three-way calling, the connection was maintained for some timeout period, to determine whether I'd really hung up, or whether it was a hook flash. It was during that period that my phone would ring. Dialing one's own number without the 212 first gave an immediate busy signal. Evidently, dialing a 212 first sent you out of the switch and back in on another path. Calls preceded by the 212 code took an extra 2 seconds or so to complete, during which you'd hear some whirring/clicking noises. When NY Telephone went to "one plus" dialing in 1980, this still worked, but of course I had to dial 1-212-929-0110. I moved out of NY in 1981, and have no idea if this still works there. (No other area I've lived in was set up to complete calls which were dialed starting with the local area code.)

I am currently doing a PhD in the "Formal Specifications of Intelligent Network Services". The main area I am interested in is the use of formal specifications of IN services in clarifying and possibly solving the problem of service interactions. One of the major problem in my research is finding examples of service interactions for supplementary services. The examples I have so far all include Call Forwarding e.g. Call Forwarding and Closed User Group, Call Forwarding and Completion of Call to Busy Subscriber (CCBS). If anyone out there knows of more examples of service interactions please let me know. I am particularly interested in hearing from people in BNR (Bell Northern Research) because they seems to be the leaders in service creation. Please reply to me by email -- not via this journal -- since I will be out of town for a couple weeks. Thanks in advance.

If the called number is not a POTS (plain old telephone service) subscriber but an extension of a PBX (private branch exchange) that is reached by DID (direct inward dialing) trunks, then the audible ring signal is not generated by the far-end central office, but by the far-end PBX. Most PBX equipment acts like a central office in this case; it does not return answer supervision (start charging the caller) until the called end answers, and it stops the ring tone at the same time. Some PBX equipment also contains ACD (automatic call distribution) equipment. This usually answers immediately, and then plays a recording telling you that you are in a queue, until an agent is available. If no recording is provided, most ACD equipment will generate ring tones, even though the call has been answered. The AT&T System 85 PBX, when equipped with AUDIX (a voice-mail and call-coverage system that functions like a multi-user answering machine) will provide off-hook supervision at the time a call is sent to AUDIX for coverage (typically after three rings, if the station still hasn't answered). AUDIX will then generate ring tone until it is able to play the called party's personal greeting. This may mean that charging begins while ringing is still audible. -- Dave Levenson Voice: (201) 647 0900 Westmark, Inc.

Anyway..to bring this long story to an end he sent Getting lightening strikes on phone lines is not uncommon. Yes, in the U.S. telephone lines have either gas or carbon surge arrestors that will conduct a surge of over 300V or so to ground. If the surge is big enough, the carbon arrestors (which are slower than gas, but cheaper) will permantly short to ground and remove you from service until the telco comes out to change them. In Bell Pub 48005 a standard single line phone should be able to survive a simulated lightning strike of 1,000Volts @ 1,000Amps. And Yes a standard AT&T, ITT or Comdial 500 and 2500 set will, as will an ATC Mickey Mouse phone. Cheap and sleezy phones may or may not survive a hit. Many answering machines will die. A few years ago a rep for an answering machine Co in the Kansas area told me that it was not uncommon for over 300 machines to be brought in for repair after a good day of thunderstorms. So anyhow, the protector that the telco puts in will help some if you have a hit, but the equipment has to do some of the work too. If you look at some equipment, you will notice surge protection devices of various kinds. There are series carbon composition resistors, varactors and back to back zeners, besides gas discharge devices. So I regret to say that you are somewhat responsable for the equipment on your lines in these days of deregulation. But in the old days, the telco wouldn't have let you put all those modems, fancy telephones or answering machines on "their network". I have seen phones and modems that are just charred circuit board, some with big holes in them after a lightning strike, so yes, you can be killed if this happens. In the 24 June issue of New Scientist (p. 55) there is a mention of someone being zapped in the ear by a phone reciever during a thunderstorm.

I'm not certain what the point of the last sentence was, unless it was merely a disdainful reference to authorized eavesdropping. Surely one does not expect the telephone company to provide the intercept circuit free of charge (the intercept circuit may often have interexchange mileage charges since the monitoring point is often not within the same central office), nor does one expect the law enforcement agency to pay for the subject's telephone line, either! Most CO (central office) eavesdropping intercepts in a BOC CO are today performed using a modified MFT (Metallic Facility Termination) circuit pack which places about a 100,000 ohm isolated bridging impedance across the subscriber line. Supervisory signaling is detected on the subscriber loop using a high-impedance electronic circuit, and the signaling is repeated in an isolated fashion using the A and B leads of the repeating coil in the MFT to "reconstruct" a CO line for the benefit of monitoring apparatus. The entire purpose of the above effort is to prevent any trouble or noise on the intercept line or monitoring apparatus from causing any trouble, noise or transmission impairment on the subject line. Some BOC's may elect to use service observing apparatus to provide the necessary isolation and repeated loop supervisory signaling. Less common are locally engineered variations which merely use an isolation amplifier from an MFT or other 4-wire repeater, and which provide no repeated supervisory signaling (which is not all that necessary, since voice-activated recorders and DTMF signaling detectors can be used, and since dial pulses can be counted by playing a tape at slow speed). Today, the use of a "bridge lifter" retardation coil for the purpose of connecting an eavesdropping intercept line is virtually non-existent since they do not provide sufficient isolation and since they provide a fair amount of insertion loss without loop current on the "observing" side. Bridge lifter coils are primarily intended for answering service intercept lines, and consist of a dual-winding inductor which passes 20 Hz ringing and whose windings easily saturate when DC current flows. Bridge lifter coils are used to minimize the loading effect (and consequent transmission impairment) of two subscriber loops on one CO line. Bridge lifter coils provide a significant insertion loss at voice frequencies toward the idle loop; i.e., the loop in use will have DC current flow, saturating the inductor, and reducing its insertion loss to 1.0 dB or less. > ] If so, does this mean that the electronically inclined and paranoid > ] among us might be able to keep track of when we are being bugged by > ] measuring the impedance and capacitance of our lines? > Actually, it's already been done. > ] Maybe Sharper Image will start selling a box to watch your line and > ] tell you when its electrical properties change in a suspicious way? > I don't know if Sharper Image sells them, but there are any number of > "security consulting" firms which do.

As the author of the second article stated, these gadgets are for the paranoid who have nothing better to waste their money on. The simple truth of the matter is that there is NO WAY for any person using ANY type of apparatus at the telephone set location to ascertain whether there is a properly installed eavesdropping device connected across their line in the CO. The only way such a determination can be made is through the cooperation of the telephone company. For that matter, there is virtually no way for any person using any type of apparatus in their premises to ascertain if there is ANY type of eavesdropping apparatus installed ANYWHERE on their telephone line outside their premises, unless the eavesdropping apparatus was designed or installed in an exceptionally crude manner (not likely today). Some types of eavesdropping apparatus may be located, but only with the full cooperation of the telephone company. The sole capability of these nonsense gadgets is to ascertain if an extension telephone is picked up during a telephone call, which is hardly a likely scenario for serious eavesdropping! These screw-in-the-handset gadgets work by sensing the voltage across the carbon transmitter circuit, and using a control to null this voltage using a comparator circuit. When a person makes a telephone call, the control is adjusted until the light just goes out. If an extension telephone at the user's end is picked up during the call, the increased current drain of a second telephone set will decrease the voltage across the carbon transmitter circuit, unbalancing the voltage comparator circuit, and thereby causing the LED to light. These voltage comparator "tap detectors" cannot even be left with their setpoint control in the same position, because the effective voltage across a subscriber loop will vary depending upon the nature of the call (except in the case of an all digital CO), and upon other conditions in the CO. Electromechanical and analog ESS CO's may present different characteristics to the telephone line, depending upon whether it is used at the time of: an originated intraoffice call (calling side of intraoffice trunk), an answered intraoffice call (called side of intraoffice trunk), an originated tandem call (interoffice tandem trunk), an originated toll call (toll trunk), or an answered tandem/toll call (incoming tandem or toll trunk). There is usually enough variation in battery feed resistance due to design and component tolerance changes on these different trunks to cause a variation of up to several volts measured at the subscriber end for a given loop and given telephone instrument. Even more significant are variations in CO battery voltage, which can vary (within "normal limits") from 48 volts to slightly over 52 volts, depending upon CO load conditions. 50 to 51 volts in most CO's is a typical daily variation. If anyone is curious, connect an _isolated_ voltage recorder or data logger to a CO loop and watch the on-hook voltage variations; in many CO's the resultant voltage vs 24-hour time curve will look just like the inverse of a busy-hour graph from a telephone traffic engineering text! In some all-digital CO apparatus, the subscriber loop signaling is performed by a solid-state circuit which functions as a constant-current (or current-limiting) device. With such a solid-state circuit controlling loop current, there is no longer ANY meaningful reference to CO battery voltage; i.e., one cannot even use short-circuit loop current at the subscriber location to even estimate outside cable plant resistance. To explode this myth even further, let's do a little Ohm's Law: 1. Assume a CO loop with battery fed from a dual-winding A-relay (or line relay, ESS ferrod line scanner element, or whatever) having 200 ohms to CO battery and 200 ohms to ground. 2. Assume a CO loop of 500 ohms (a pretty typical loop). 3. Assume an eavesdropping device with a DC resistance of 100,000 ohms (this is still pretty crude, but I'm being generous with my example). 4. Using some simple Ohm's law, the presence or absence of this hypothetical eavesdropping device at the SUBSCRIBER PREMISES will result in a voltage change of less than 0.5 volt when measured in the on-hook state. This voltage change is much less than normal variations of CO battery voltage. 5. Using some simple Ohm's law, the presence or absence of this hypothetical eavesdropping device at the CENTRAL OFFICE LOCATION will result in a voltage change of less than 0.2 volt when measured in the on-hook state. This voltage change is an order of magnitude less than the expected normal variation of CO battery voltage! Measuring voltage variations on a subscriber loop in an effort to detect a state-of-the-art eavesdropping device is meaningless, regardless of resolution of a voltage measuring device, since the "signal" is in effect buried in the "noise". Moving on to the subject of subscriber line impedance... There is simply no way for any device located on the subscriber's premises to obtain any MEANINGFUL information concerning the impedance characteristics of the subscriber loop and whether or not anything "unusual" is connected at the CO (or for that matter, anywhere else on the subscriber loop). There are a number of reasons why this is the case, which include but are not limited to: 1. The impedance of a typical telephone cable pair results from distributed impedance elements, and not lumped elements. Non-loaded exchange area cable (22 to 26 AWG @ 0.083 uF/mile capacitance) is generally considered to have a characteristic impedance of 600 ohms (it actually varies, but this is a good compromise figure). Loaded exchange area cable, such as H88 loading which are 88 mH coils spaced at 6 kft intervals, is generally considered to have a a characteristic impedance of 900 ohms (it actually varies between 800 and 1,200 ohms, but 900 ohms is generally regarded as a good compromise figure for the voice frequency range of 300 to 3,000 Hz). What this means is that a bridged impedance of 100,000 ohms located in the CO on a typical subscriber loop will result in an impedance change measured at the SUBSCRIBER LOCATION of 0.1% or less. That's IF you could measure the impedance change at the subscriber location. 2. As a general rule of thumb, the impedance of an exchange area telephone cable pair changes ONE PERCENT for every TEN DEGREES Fahrenheit temperature change. Actual impedance changes are a function of the frequency at which the impedance is measured, but the above rule is pretty close for the purposes of this discussion. 3. Moisture in the telephone cable causes dramatic changes in its impedance characteristics. While this may appear obvious in the case of pulp (i.e., paper) insulated conductors, it is also characteristic of polyethylene (PIC) insulated conductors. Only gel-filled cable (icky-PIC), which still represents only a small percentage of installed cable plant, is relatively immune from the effects of moisture. 4. From a practical standpoint, it is extremely difficult to measure impedance in the presence of the DC potential which is ALWAYS found on a telephone line. The subscriber has no means to remove the telephone pair from the switching apparatus in the CO to eliminate this potential. Therefore, any attempt at impedance measurement will be subject to DC current saturation error of any inductive elements found in an impedance bridge. The telephone company can, of course, isolate the subscriber cable pair from the switching apparatus for the purpose of taking a measurement - but the subscriber cannot. In addition to the DC current problem, there is also the problem of impulse and other types of noise pickup on a connected loop which will impress errors in the impedance bridge detector circuit. Such noise primarily results from the on-hook battery feed, and is present even in ESS offices, with ferrod scanner pulses being a good source of such noise. While one could possibly dial a telephone company "balance termination" test line to get a quieter battery feed, this still leaves something to be desired for any actual impedance measurements. 5. Devices which connect to a telephone pair and use a 2-wire/4-wire hybrid with either a white noise source or a swept oscillator on one side and a frequency-selective voltmeter on the other side to make a frequency vs return loss plot provide impressive, but meaningless data. Such a plot may be alleged to show "changes" in telephone line impedance characteristics. There is actual test equipment used by telephone companies which functions in this manner to measure 2-wire Echo Return Loss (ERL), but the ERL measurement is meaningless for localization of eavesdropping devices. 6. It is not uncommon for the routing of a subscriber line cable pair to change one or more times during its lifetime due to construction and modification of outside cable plant. Outside cable plant bridge taps (not of the eavesdropping variety) can come and go, along with back taps in the CO to provide uninterrupted service during new cable plant additions. Not only can the "active" length of an existing cable pair change by several percent due to construction, but lumped elements of impedance can come and go due to temporary or permanent bridge taps. The bottom line of the above is that one cannot accurately measure the impedance of a telephone pair while it is connected to the CO switching apparatus, and even if one could, the impedance changes caused by the installation of an eavesdropping device will be dwarfed by changes in cable pair impedance caused by temperature, moisture, and cable plant construction unknown to the subscriber. In some previous discussions in Telecom Digest about a year or so ago, there was mention of the use of a time domain reflectometer (TDR) for localization of bridge taps and other anomalies. While a TDR will provide a rather detailed "signature" of a cable pair, it has serious limitations which include, but are not limited to: 1. A TDR, in general, cannot be operated on a cable pair upon which there is a foreign potential; i.e., a TDR cannot be used on a subscriber cable pair which is connected to the CO switching apparatus. 2. A TDR contains some rather sensitive circuitry used to detect the reflected pulse energy, and such circuitry is extremely susceptible to noise found in twisted pair telephone cable. A TDR is works well with coaxial cable and waveguide, which are in effect shielded transmission lines. The use of a TDR with a twisted cable pair is a reasonable compromise provided it is a _single_ cable pair within one shield. The use of a TDR with a twisted cable pair sharing a common shield with working cable pairs is an invitation to interference by virtue of inductive and capacitive coupling of noise from the working pairs. 3. Noise susceptibility issues notwithstanding, most TDR's cannot be used beyond the first loading coil on a subscriber loop since the loading coil inductance presents far too much reactance to the short pulses transmitted by the TDR. There are one or two TDR's on the market which claim to function to beyond _one_ loading coil, but their sensitivity is poor. There is simply no device available to a telephone subscriber that without the cooperation of the telephone company which can confirm or deny the presence of any eavesdropping device at any point beyond the immediate premises of the subscriber. I say "immediate premises of the subscriber" because one presumes that the subscriber has the ability to isolate the premises wiring from the outside cable plant, and therefore has complete inspection control over the premises wiring. I have used the phrase "without the cooperation of the telephone company" several times in this article. No voltage, impedance or TDR data is meaningful without knowing the actual circuit layout of the subscriber loop in question. Circuit layout information includes such data as exact length and guages of loop sections, detailed description of loading (if present), presence and location of multiples and bridge taps, calculated and measured resistance of the loop, loop transmission loss, etc. Ain't no way that a telephone company is going to furnish that information to a subscriber! Sometimes it's even difficult for a government agency to get this information without judicial intervention. Despite what I have stated in this article, readers will see claims made by third parties as to the existence of devices which will detect the presence of telephone line eavesdropping beyond the subscriber's immediate premises. With the exception of the trivial cases of serious DC current draw by an extension telephone or the detection of RF energy emitted by a transmitter, this just ain't so.

I have had the same phone number since before this change took place. For the record, AT&T is my primary long distance carrier. I discovered an interesting feature a couple of nights ago involving three-way calling and equal access. If, while talking on the phone to someone, I flick (my word for pressing the switch hook in order to activate three-way calling) and call 10-666-1-, after the , I get a ringing following by an error message "Your long distance call cannot be completed as dialed..." Fine, that sounds like maybe an invalid long distance carrier code, you say. So I hang up on this message by flicking a few more times. However, it is no longer possible for me to dial any other calls after flicking! If I flick and begin dialing any phone number, I get the same message given above after dialing any of 10,1,0,, or 00. (I didn't try 0 or 0). This seems to last for the duration of the original call, or at least for quite a long time. However, hanging up the phone entirely, disconnecting the original call, solves the problem. A feature(?) of the three-way calling in my area is that if I flick, wait for the dial tone, and then hang up, my phone will begin ringing until I answer it, at which point I'm back with the original call. Handy for transferring between phones on the same line in different rooms. (Is this true of three-way calling in all areas?) Anyway, I found that if I do the flick-and-hang-up trick, things also go back to normal. So is 666 the code for a Satanic long distance carrier, or what? -- Nathan Glasser fnord nathan@{mit-eddie.uucp, brokaw.lcs.mit.edu} ST Quote: "I've never heard a malfunction threaten me before." - Sulu Question: "Our prices range from $20-$40, and up." What does that mean? [Moderator's Note: It is worth noting that '666' has never been, and probably never will be assigned as part of a carrier access code, due to the ignorance and superstition so prevalent among many Americans. Illinois Bell even has a hard time getting people to take service on the old Monroe CO, which went from Monroe to MONroe to MO-6 and finally '666'. Checker and Yellow Taxicab Radio Dispatching was on there for over sixty years: MON ==> MO 6 ==> 666-3700, and they finally gave up and moved to a different CO. They say they got a lot of harassing phone calls from, uh, strange people.

The response I got was to the effect that if a payphone customer needs operator help because a payphone won't accept coins, the customer will be charged at the coin-deposit rate, once the NJB software is updated to let operators bill like that. Through this posting, I'd like to know what readers' experiences have been, both in NJ and elsewhere. In the four cases I complained about, I could not put coins in a payphone. In one case, a payphone was dead, but a "coinless" phone right next to it worked; in the second case, coins went right from the slot to the coin return, and in the other two cases, the slot was blocked (and as it was later explained to me, it meant the coin box was full). Also, in all four cases, only intra-LATA calls where involved (two local and two toll calls), and all the phones were NJ Bell phones. In all these cases, I called the operator (from the adjacent coinless phone in the first case, from the phone that didn't want my money in the other three cases), explained the problem, and the operator happily offered "alternative billing"; in all cases though, even a credit card call would have been more expensive than feeding in coins. In each case I said OK, but that she could bill my credit card only the amount of a coin-deposit call. In all cases, she refused, as did her supervisor. What finally prompted me to complain though was not the fact that the operator wouldn't work with me, but when, as usual I told the operator that she could charge only the coin deposit rate to my credit card, she merely repeated her question about alternate billing, and as I was repeating my response, she hung up on me. I have not encountered a payphone that didn't want my money since then, so I'm just curious to find out if others have had NJ Bell work with them in a case like this, as well as how this problem has been handled elsewhere (this letter and response were written about four months ago). -- Stan Krieger Summit, NJ ...!att!attunix!smk ------------------------------ Date: Fri, 14 Jul 89 08:17:10 EDT From: john@kodak.com Subject: Telephone Intercom Wanted I have six telephones in my house. I'd like to be able to call from one phone to another by dialling a one or two digit code. Does anyone know of a box that does this at a reasonable price? I'd prefer a system that understands both tone and pulse dialling, but tone only would be OK. I imagine that such a system would require me to dial an extra digit like '1' or '9' to connect to the outside line. It should have a "conference" capability, so that when we make an outside call, my wife and I can be on separate phones. Six phones to one outside line will meet my current needs. Some expansion capability, maybe ten phones to two lines, would be nice. Price is important. It shouldn't cost more than, say, a VCR. Each phone has a separate set of wires that all connect to a common terminal block where the phone line enters the house. I envision a unit that I can mount right at that box.

Any caveats regarding this, particularly with using data modems? 2) New England TelCo called me and offered a new service called "Intellidial" which claims to offer all the services of a Merlin or similar key system onto your regular phone lines from the central office. Since I'm about to move into new office space and I'm looking for a key or hybrid anyhow (suggestions very welcome!) I bit. It can be ordered on a month by month basis and would only cost me about $50 to try for one month in this location so what the heck. I was just wondering if anyone has any experience with this service, particularly things we should try or ask about before committing to it rather than a key/hybrid system. -Barry Shein Software Tool & Die, Purveyors to the Trade 1330 Beacon Street, Brookline, MA 02146, (617) 739-0202 Internet: bzs@skuld.std.com UUCP: encore!xylogics!skuld!bzs or uunet!skuld!bzs [Moderator's Note: In reference to your question (2) above, here in Chicago this is called "Starline", and I've had it on my phones for a couple years with good results. In addition to intercom service between phones, Starline (or Intellidial as you called it) offers the ability to pick up any ringing phone from any other location; transfer of calls between phones; distinctive ring for intercom versus incoming calls from outside, and more.

New Jersey has 2 area codes (not for long); 201 and 609. But that's not what I came to talk about. I came to talk about the Hoboken "local calling area". The Hoboken area has a 3-tier system just like Boston, local calls are the 1 message unit calls for measured service if you buy unmeasured service. Here you can have both in the same house, so if you make alot of calls to zone 2 and 3, you can get a flat rate line for the zone 1 calls and a measured line (which includes 30 units) for zone 2 and 3. Measured service has the advantage that most of the charge for the line is in providing the message units. In Boston, Measured service costs $3.50/month and $2.75 of it is paying for the 30 message units, so you get a phone line for $0.75 if you make enough calls to warrant getting it. Once you leave the "metropolitan area" near Hoboken and Newark, you go into Suburban NJ, where the calling plan basically works like most suburban systems. Local calling to the areas that border yours, and maybe an exchange or two further, and toll calls for the rest. New Brunswick had a fairly large local calling area, and I never lived so far away from Rutgers that calling in via data was a toll call. In this area it is just like the rest of them, you can't get measured and flat rate service in the same area; however, in most of NJ, measured service is designed for those who can't afford or don't want flat rate service. The default is flat rate. The rates for phone service in NJ are quite reasonable. Now onto California. Much of California is a desert wasteland with basically local calling areas much like NJ with toll calling everywhere else. Notable exceptions are the Bay area and LA (where most of the people live ;-)). In these areas, zone calling replaced much of the major local calling some years ago. Local calling areas shrunk in size drastically, and now some places in San Francisco are toll calls (as opposed to cheaper Zone calls) from other places in San Francisco. Basically Pac Tel tried to find some way to increase revenues and the PUC bought it. Right now there is a plan in consideration for returning zone 2 calls to the local calling area in exchange for raising the rate for local service (currently set to $8.25/mo). It is cheap to get phone service in California, but you can't call anywhere. In most cities I have lived in, the zone charges are reasonable, and toll charges either are or aren't. In CT, the toll charges are quite high and SNET receives alot of revenue from them. Local exchange rates are also quite high. SNET has a well managed rate system in my opinion. California has outrageous toll calling rates. The price for a call to San Francisco from LA is higher than a call to Boston from LA by a hefty margin. New Jersey, and Mass, have reasonable toll calling rates within their states. I can talk for 5 minutes to someone on the other side of (508) for about a buck (so they advertize), and it's not much of a bite out of my phone bill to use the phone. I like Mass' multiple-choice local exchange service rates (measured, flat rate, metropolitan, circle calling, etc), since you can pay for what you get. One thing I remember in LA which was being phased out when I lived there was FEX service. If you lived, say in Santa Monica (213-828) and wanted to call the USC dialups (213-743), it was generally suggested that you get a Culver City (213-558) or Beverly Hills (213-556) Foreign Exchange line and make the calls for free. At that time, FEX charging was a bit higher than regular lines, but it was worth it in the cost savings on data calls which had high holding times. Flat rate FEX was axed at the time I was there, so if you *did* get a FEX, you had to pay 20% more than the normal 1 message unit rate on calls made from the FEX. You could still receive calls, but you couldn't make the calls. PacTel seems to have something against DATA calls. NET in Boston doesn't mind them (NET converted all their interexchange lines to T1 and send 24 calls on each set of 2 pairs), however they insist that incoming data lines be business service (higher cost). You don't need FEX service in NET land unless you live outside of the extended Metropolitan Calling area, and want to call into it. You then needed a FEX to the nearest exchange that has Metro service (for residences) or a FEX to the nearest exchange inside the metro calling area, or 1 message unit from your target exchange (business). Nowadays FEXes in California are extremely expensive. Mileage is something like $15/mile and you don't get flat rate service (the installation charge is outrageous). They really discourage the use of FEXes but don't offer any alternative to them. If you make more than $600/month in data calls to one specific number, then you can justify a FEX for that one number. If you require further service, PacTel recommends that you get several PBXes or a Centrexen and run tie lines between your locations and use them to make your calls. Both PacTel and NET are pushing 800 service for incoming use and OUT-WATS for outgoing use to save money. Of course, you don't save much. Basically, PacTel is pushing the high cost of their past mistakes in the setting up of phone service (loans they have to pay back, interest, etc) on those who use the network, while other phone companies are charging their customers for basic service to cover costs (SNET is doing BOTH -- they were the first phone company to be all-dial-it-yourself back when Step Switching was the rage, and now they have to convert to electronic switching and need capital to do it). One final note: In LA, I can remember choosing my place of residence based on the local calling area, particularly if it would be local to USC, where I worked, and got my daily fix of compute cycles. :-) --jsol ------------------------------ Subject: Local Area Calls in the Bay Area of California Organization: sybase, inc., emeryville, ca.

For business users, ALL calls are timed, including the ones to very near-by places. Measurement is done in 'units', which is a function of the length of the call times the distance. A one minute call could range between 0.6 and 5 units, depending on the distance between subscribers. Between 9 PM and 9AM daily, the total number of units used is adjusted by 33 percent. For residential subscribers, the situation is a little different. The charge for a 'local call' is one unit during the day, and 0.67 units during the 9 PM to 9 AM time period each day. The 'local area' calls are untimed, and are always one (or .67ths) of a unit. The local area is a relative matter. It includes your own switching center, as well as most, if not all, of the ajoining offices. Your local area is always approximatly eight miles in any direction of your switch. Calls outside this area are timed, and the units keep adding up. The charge is calculated on length of time the connection was up times the mileage between switches. If your eight mile -- your switch and neighbor switches -- crosses the boundary from one city to another, fine. If it crosses the Indiana/Illinois border, again fine. If a call is timed, then the cost will be at least two units, and probably a lot more. Like the business deal, calls made between 9 PM and 9 AM are given a thirty percent discount. For both business and residence subscribers, the cost per unit ranges from 5.2 cents for the first thirty units. The cost of units drops to 3.5 cents each as you use more. It is worth noting that if you make a lot of your calls in the evening, the 33 percent discount in *the number of units used* -- as opposed to the cost of each unit -- it takes longer to reach the required number of units in Illinois Bell's tariffs. Residential users with modems typically use $100 - 150 worth of units per month. There is virtually no such thing as a 'free call' in northern Illinois. We had unlimited calling, (that is, calls from around Chicago) until 1987. In March, 1987, this plan was dropped (actually, there were about 100 variations on the plan) and the ESS computer took over. ------------------------------ Date: 14-JUL-1989 03:10:50.62 From: "DOUGLAS SCOTT REUBEN)" Subject: Local Area Calls in Hartford, CT/Metro New York City Area In response to jsol's post about untimed/unlimited toll-free calling areas, I noted that he mentioned how Hartford was expanding their local area. About 2 years ago, we got a ballot from SNET asking if Middletown customers (203-344,346,347,638) would agree to pay a slightly higher monthly rate if in return SNET would give us unlimited toll-free access to Hartford. In light of what appears to be an expansion of the Hartford toll-free area, I am wondering if anyone has heard if the plan to allow toll- free Middletown -> Hartford calls has been approved? Also, as for NYC, there is no unlimited service there. Callers IN the 5 boroughs of NYC pay 10.2 cents for a call anywhere in the 718/212 areas, or between the two. (This is daytime...standard eve/night discounts apply). If you have unlimited service, you can talk as long as you want (years, for that matter...), and still pay only 10.2 cents. There used to be unlimited calling, or "flate rate", where you pay a certain amount per month and all calls within your local area (nearby exchanges) were free. They don't offer this anymore in NYC, but people who had it before this was changed can still keep it. Some of the "flate rate" area crosses into area code 516 for certain border communities in Nassau County. I assume this is the same case near the Bronx/Westchester Co. Line. The nearby suburbs in New York all have unlimited "flat rate" as an option, but there are no "free" calls to NYC, from anywhere, as there are in the Boston suburbs. Recently down-state New York set up a new Regional Calling Plan, which replaced the "band" system of calling. Previously, you were billed by distance, IE, a call from NYC to Montauk Point at the tip of Long Island would be something like a Band "E", the most expensive (or was there an "F"?). Now, calls are billed by area. If you call within your area (NYC for example) you pay a set rate for that area (10.2 cents in NYC). If you call from one area to another, ie, NYC to Westchester, your call is not itemized but billed as a "Westchester Region" call, and you pay whatever the fixed rate NYC to Westchester is. This is a bit simpler than the "band" calling, as there are only a few ares to remember (NYC, Nassau Co, Western Suffolk Co, Eastern Suffolk Co, Lower Westchester Co + Greenwhich/Byram CT, and Upper Westchester Co.) Moreover, you don't have to know the distance of your call, but just the area you are calling in order to know what you will pay. Some customers are paying more because of this, ie if you live in the nothern section of "Lower Westchester" and want to call the southern section of "Upper Westchester", but are not local. However, if this happens, NY Tel will credit you with the difference between what the new plan charges you and what the old plan would have charged. This is automatic and appears on every bill where it is applicable. I'm sure there are plenty of things I left out, but so as not to stretch the patience of readers who are not from the area, I'll end it here. I'm almost sure that's how things work in the NY Metro area, but not having been in one place for a while now, I'm not sure...As usual, corrections are welcome... -Doug dreuben@eagle.wesleyan.edu dreuben@eagle.weslyn@wesleyan.bitnet (and just plain old "dreuben" to locals! :-) ) (Hmmm...I need a new .sig file...That's *so* passe' !) ------------------------------ From: Steve Spearman Subject: Local Area Calls in Metro Denver Date: 14 Jul 89 14:06:54 GMT Organization: AT&T, Denver, CO In article , techwood!johnw@gatech.edu (John Wheeler) says: > We do not, and never have had metered service here in Atlanta, > discussably (which we have done on here) the largest local > calling area.

From: "Michael A. Patton" I have a side note to JSol's message about Boston area calling plans. I used to live in a suburb quite a way outside Boston (it's now part of area 508) and had Metropolitan service. The free calling area consisted of two non-contiguous areas, the normal local area and the Metro area.

About 6 weeks ago, I was desperate to get through to a Technical Support number for a mail-order place I had bought some computer equipment from. Of course the line was nearly constantly busy. Finally, I decided I would just keep dialing the number as long as it took, until I got through. Since I was calling from the office, I was using my US Sprint Fon Card. After probably a half hour of repeatedly dialing the same busy number, I started getting a recording that my Fon Card number was not authorized. By this time, I was tired of dialing anyway, so I figured maybe it was just Sprint having a computer problem or something, so I didn't try again till the next day. Same thing. So I called Sprint Customer Service. They cross-examined me about my address, various details about my account, what number I had been calling and when, etc. Once they determined that I was really the person who belonged to that account, they said the unusually high number of calls in such a short period of time had triggered their security system. Apparently Sprint Security tried to contact me, but when I moved a couple years ago, I forgot to tell them of the change of my home phone number. So they called the number they had, which, of course, has been assigned to someone else now, and I guess they figured they had really caught a phone hacker, and they cancelled my Fon Card. The representative said they have no way to reinstate a cancelled card, so they would have to give me a new number and card, which would take two weeks. I certainly had mixed emotions on this. I was glad to know that Sprint does some type of monitoring for security purposes, but it seemed like they jumped the gun a bit--since all the calls I attempted had only reached busy numbers, no revenue was being lost. Plus, wouldn't it be natural to assume that since I had kept getting busy signals, that it really was me calling over and over again, trying to get through? (Also, I had called this same number several times in the preceding weeks, and gotten through--a quick check of my billing information would have shown this.) Having to wait two weeks to get another Fon Card is goofy, too. It makes the customer suffer for what was really Sprint's problem. -- "MAN USES TAPE TO STICK Dave Fiske (davef@brspyr1.BRS.COM) HIS TOE BACK ON!"

What you observe is ringback tone "out of phase" with the ringing current on the called line. It will, however, have identical cadance. Ringing current may actually be applied before the first cycle of ringback tone. But it is incorrect to say that which the caller hears has NOTHING to do with ringing current. -- John Higdon | P. O.

Assuming that the interdiction stemmed from an oddity of step-by-step switching, I asked my Dad, who worked for BCTel from the early 1950's until his retirement in the mid 1980's, and was part of the team that converted Vancouver to automatic switching. For reasons that were never clear (testing purposes?), the position in Strowger switches that corresponded to NNX-0000 was left blank, and calls could not be completed to such a number. Now, of course, any number is fair game, but there are still echos of this. For example, a system used at BCTel to keep track of service orders could not process an order for NNX-9999 or NNX-0000, as it used such numbers internally as sentinels. Speaking of local calling areas, though Vancouver's is largish, there are some *huge* calling areas in the interior of B.C. You can phone from Baker Creek, B.C. (604-249) to Macalister (604-993) on a local call.

Eight minutes for .43. =-=-=-=- ( DP: If this is the case, then everyone better be very careful about using the 10288, etc., numbers as one might be incurring charges that one's not aware of. Patrick, can you shed some additional light on this?? ) Don Peaslee [Moderator's Note: Baloney, baloney, baloney! Prefixing a call with 10288 does nothing except force the call to be routed via AT&T. It does not incur extra charges other than whatever slight difference there is between AT&T rates to the point in question and whatever other carrier was being used. If you dial an intra-lata call (a call within your own town, for example) using 10288 as the leading code, it is likely the call will be rejected and you will have to dial over again. I've tried this, and at least here in Chicago, dialing 10288 followed by a seven digit (or ten digit, but within IBT's lata) number and a recording says the call cannot be completed as dialed. Whether or not you get 'cleaner' lines by forcing your call over AT&T is a very subjective matter. But in and of itself, 10288 is a way of routing long distance calls -- not a special feature to insure clean lines at an added cost.

Unmeasured service is available, except that calls outside of an 8-mile radius of where you are calling from are "zone" charges. If you happen to live in the GTE service area, just about everywhere else in the valley ("silicon" valley, also known as 408) costs money (ridiculous amounts, at that) to call. I happen to be one of these unfortunates; by being less than a quarter mile from where the pac*bell service area ends, my phone bill is about three times what it would be otherwise (or six times what would be reasonable). There is also no "metropolitan" option, so it all boils down to getting the most strategic 8-mile radius you can. watcher@uuwest.UUCP [Moderator's Note: And per your notes to me: 'watcher@uuwest.uucp' is a bad address.

Sol points out, new FX (foreign exchange) lines in the LA metropolitan no longer have flat rate service and their installation is VERY expensive. However, those of us who have had FX lines for years still have "grandfathered" flat-rate service and, moreover, with call-forwarding, can, in effect, use them for two calls simultaneously. I live in a suburban GTE exchange area from which the call to UCLA is a toll-call. However, an adjacent GTE exchange has flat-rate service both to my exchange and also to UCLA. I have a flat-rate FX line from that exchange (installed in 1974); the basic rate is about $54.00 per month -- mostly mileage charges. I have call-forwarding on that line to a local-exchange line, also in my home. This allows friends to call us without paying a toll charge at the SAME time I am using the line for an outgoing modem call. Actually, we have TWO local-exchange lines in the home, on a "rotary" and the FX line forwards to the first. I was most surprised to discover that if one of my rotary lines is idle while the FX line is forwarding one call to the other rotary line, and the FX line receives a second call, then the caller gets a busy signal. That is, even though the line being forwarded to is the first of a multi-line rotary, with idle lines, only one call at a time will be forwarded! A substitute for this FX line, which would be cheaper and is available without "grandfathering" but is more of a nuisance, would be to have one or two flat-rate ordinary lines in a friend's home in the adjacent exchange area. I could set one to always forward to my home and the second to always forward to UCLA (for modem calls). Varous devices sold by Comcor allow remote changing of forwarding numbers using various tricky strategies. dgc David G.

Their first proposal said that there would be measured service for all New Mexico calls. The New Mexico State Corporations Commission (which has oversight responsibilities for all public utilities in the state) said nothing doing. Next proposal was to drastically split local calling areas, effectively converting intra-city calls in Albuquerque and Santa Fe often into long distance calls. Again, the NMSCC rejected the proposal. The final arrangement was what we still have. First, measured service is allowed only if unmeasured service is also offered; second, unmeasured service will be priced as if it were all that was offered; third, incorporated cities cannot be split into more than one local calling area.

The poster asked about connecting six telephone sets to one CO line, providing intercom, conference calling, and similar PBX features. The poster also asked if it could be done for the price of a VCR (a couple of hundred $ ?). Residential Centrex (aka StarLine) service was suggested. This is probably less expensive than a VCR, but requires six pair from the CO. What do they charge for the installation? How many months of the service can one buy for the price of a VCR? Another option is the residential PBX. Mitel makes (or at least, made) a small switch called the SX-5. This supports six tip-ring stations, two CO trunks, and offers the usual PBX features. It allows locally-stored speed-dial, conference calling, call-forwarding, universal answering, selective ringing, call hold, call transfer, call-waiting, and data security. As is usually the case with the premises-based vs CO-based comparison, the better price depends upon how long you intend to use the service. The Mitel SX-5 used to sell for about $700 or almost three times the price of a VCR. But you only buy it once. No extra monthly charge for its use. You maintain it. You own it (and can sell it, perhaps). We use one here to connect a bunch of computers. We have five modems on two CO lines. Key systems are also available. The central switch is less expensive than a PBX, but the telephone sets are not standard tip-ring, and tend to cost more. Not a definitive answer, but perhaps a few points for consideration. -- Dave Levenson Voice: (201) 647 0900 Westmark, Inc.

A BOC calling card >is< an AT&T calling card. ... You might think so, but it's not so. The calling card numbers are made up by the operating companies and then picked up by AT&T. Although the card numbers are the same, the BOC cards and the AT&T cards are separate. Your AT&T card is good for AT&T calls, your BOC card good for intra-LATA calls. All of the BOCs have billing arrangements with each other, so you can use your BOC card for intra-LATA calls anywhere. Other LD companies could perfectly well use the same numbers, but for reasons that now seem largely historical, they all make up their own calling card numbers which have the same format as the BOC numbers but different PINs. An insert in my Sprint bill a few months ago mentioned that they're starting to make agreements with the BOCs to take each other's calling card numbers. Furthermore, I have found that if I go to a payphone and dial 10333-0-number, Sprint will take my BOC card number but not by Sprint FON number. Curiouser and curiouser. -- John R.

Date: 16 Jul 89 01:25:19 GMT Organization: Air Force Institute of Technology; WPAFB, OH Due to popular demand (by my wife :-), I am considering ordering a second line. This line will only be used for my modem, and only for local out-going calls (mainly for dialing in to work and to a local BBS). After reading a recent article in this group in which the author had to demand some unadvertised service, I was wondering if perhaps there was some little known service I should request. At any rate (no pun), what is the cheapest service that will meet my requirements? Is there such a thing as an out-going only line? Thank you. -- Joe Hamlin [Moderator's Note: Yes, there are one way outgoing only lines. If someone dials the number while you are on it, they get a busy signal. If the number is dialed when it is not in use, it cuts to an intercept message, "The number you dialed, 123-4567 is not in service for incoming calls." I would not personally box myself in in that way. You might want to receiving incoming data calls from time to time; then what? Just keep the number non-published, and get as large a calling area package for the line as your telco allows.

The local calling area for Natick was of course local, and calls into Boston were local if you have Metro service. What I was trying to point out is for places like Stoneham (617-438), you could call 1-508-653-XXXX to Natick for free if you had Metropolittan service, and you could call ANYWHERE THAT HAD METROPOLITAN SERVICE from that zone, but from Somerville and Cambridge that is not the case.

Intelledial lets you have between 2 and 6 lines in your home or office, and connect them together like centrex. You can transfer between the lines and have busy-call-forwarding and call-forwarding-no-answer and other features. Merlin costs more up front, but gives you more control over your services. If you want to just try something and see how it works, use intelledial. If you are sure you want a key system, go with merlin.

I installed customer premise stuff for 5 years, and still take care of several clients that have unique requirements/systems/just plain want me doing their work.

That's 10 complete 1A2 systems, including all the station wire (25 & 50 pair) we could remove.. We reconditioned all the equipment (16 man-hours) and later sold 6 of them for $300-$700 each.

I have a few questions that I hope someone could answer for me. . . The research I've done (calling vendors) indicates that there are switches designed to "screen" FAX calls, only passing voice calls on to the connected phone system. I found a fax machine (Sharp UX350) with one of these switches built in. I was told it would do what I wanted it to do. It does, with a single phone hooked up to it. When introducing Sharp and AT&T (now be nice, boys), we had a little conflict. FAX messages are intercepted... that part works fine. Voice calls, however, get Merlin confused. When Sharp passes on the ring, (it's supposed to ring the phone for 15 seconds if it isn't a fax) Merlin doesn't recognize it as a ring. hmmm.... I've tried the fax machine with another "smart" phone system... they're too smart to be outsmarted, it seems (the other one was TIE EK612). Now, since we have so many technology junkies in one place... does anyone know of a switch that will do what I want it to do on the Merlin (or other) phone system?? PS - Sharp is the first fax I've found with this switch built in ... the others I've heard of are all external. Viking is the one that comes to mind, but it sounds like it will have the same problem with the Merlin. PPS - Anyone had any experience with the Merlin BTMI for this purpose??

AT&T and hence the entire non-competitive long distance industry has been charging for directory assistance for some years now. Actually, in all fairness, AT&T does allow a few free information calls per month if a long distance call is made to offset the call to information; no other carrier that I know of does. > [Moderator's Note: ... > Sprint also issues [calling ] cards, as does MCI.

Capek" Subject: Telephone Number Formats I'm looking for a source of information on the formats of city codes (number of digits), exchange numbers (number of digits), lengths of phone numbers, and international access codes for (ideally, all) countries. Information about the form in which direct-inward-dialing is provided, if available, would also be helpful. Machine-readable would be ideal, but beggars can't be choosers. Separately, I'd like to ask a question about long distance access codes. In many countries, city codes are commonly quoted with a leading 0. In all cases that I know of, this leading 0 is really an access code, and isn't intended to be used, for example, when the city code is dialed from outside the country. Is there any case in which this isn't true? That is, is there any country which has an city code which starts with a zero? Peter Capek IBM Research -- Yorktown Heights, NY [Moderator's Note: We had a complete listing of international country codes published here just a few issues ago.

Reid" Subject: Local Calling Area in Metro Rochester, NY I will discuss Rochester, NY's local calling plan offered by Rochester Telephone Corporation (the largest independent telephone company in the country, I believe). Exchanges within the city of Rochester is quite large: 68 exchanges for Rochester itself alone plus 38 suburban exchanges for a total of 106 exchanges available to the subscriber. Almost all suburban echanges have local calling to Rochester exchanges with the exception of Avon exchange which does not have any local calling plan except itself. Depending on what service you have (flat-rate or message-rated), you have a pretty large area to call! With flat-rate service (which I have) is very useful to modem callers. (Recently, I heard that Rochester Telephone sent a rate change request to the Public Utilities Commission that they put a 80 calls cap on flat-rate calls. In other words, if I make more than 80 calls, they will charge me the message unit rate of 8.3 cents over the 80 for my flat-rate service. I believe it is an incentitive for me to switch to the 80 call allowance ($8.53 versus $11.61. There is a public outry now so I don't know if this will get approved or not.) The exchanges are grouped by Group Number which corresponds to the monthly charges. There are 5 groups: Group 2 (Avon, Cohocton, Nunda) Group 3 (Atlanta, Castile-Gainsville-Silver Springs, Dansville, Hemlock, Leicester, Mt. Morris, Perry, Springwater, Warsaw, Wayland) Group 4 (Canandaigua, Geneseo, LeRoy, Livonia, Naples, Pavilion) Group 5 (Wyoming) Group 9*** (Bergen, Brockport, Caledonia, Churchville, E.

He has described the system which 'caught' Mr. Fisk, the telecom reader who complained that his account was pulled without warning. As Mr. Fisk said, Sprint tried to contact him to determine what the deal was with his card. Patrick, I think you are being a bit harsh on US Sprint. They have to do something to stop the code abuse that goes on. One of their major problem areas is Port Authority and Grand Central Station in NY. Certain individuals look over the shoulder of people using calling cards, and then sell the calling card number to anyone who happens by. US Sprint's solution to this was to disable all FONCard access from Port Authority. I'm not sure if this is still the case... One time my friend travelled to Boston to work with one of their larger customers who had been experiencing code abuse. People had been dialing in to the customer's PBX and dialing out on a US Sprint WATS line. Nearly a hundred thousand dollars worth of calls to Haiti had been spent. Naturally, Sprint did not charge the customer for any of these calls. The phone bill for one month during the customer's "code-abuse" problem period was more than a foot thick! -- Steve Elias -- eli@spdcc.com, eli@chipcom.com [mail to chipcom.chipcom.com bounces!] -- voice mail: 617 859 1389 -- work phone: 617 890 6844 ------------------------------ Date: Mon, 17 Jul 89 23:02:49 CDT From: TELECOM Moderator Subject: Re: US Sprint Code-abuse Policies In the message before this one, Steve Elias describes a problem which has plagued telephone companies for years; namely fraudulent billing information passed to the operator, which ultimatly is written off uncollectible and later passed on to legitimate users in the form of rate increases. The most famous, or would you say infamous case on record was several years ago when New York Telephone went before the state commissioners to seek an increase in rates. The question arose, 'How much did NY Tel write off in uncollectibles due to calling card fraud last year?' .....the answer: $7 million! So it a problem which requires action. But I will suggest that if for no other reason than their size, anything US Sprint gets, the Mother Company gets four times as much of. And how does AT&T handle fraud? Certainly not by red-lining certain parts of cities where fraud is prevalent, as Sprint has done with NY Port Authority or Grand Central. Suppose I was a Sprint customer, and innocently took the bus to New York and got off at the terminal. Ah yes, I am supposed to call home right away and let the folks know I arrived okay....but at the last minute, in quite an inappropriate way, I find out *my* calling card won't work there either. Sprint may choose to say, 'so what'....but that is simply indicative of their attitude in general toward their customers. If AT&T pulled something like that, they would be immediatly censured by the FCC. And of course I am sure there are no signs on the payphones saying "phones won't work with Fon Cards", so it is left to the confused telephone user to wonder why the calling card issued just last week which worked fine at home won't work here now that he has no change, and needs to make an urgent call. I operated a BBS here in Chicago for several years called . It was open without pre-registration to all callers except that to post messages, one had to have a validated password. It was NOT a phreak board, yet there were phreaks from all over the country calling it at one time or another. One day at my office -- a place totally unrelated to any and all of my computer hobby activities over the years -- a miserable little man called me, identified himself as "Sprint Security" and demanded a full print out of all the users on my system. He kept calling, threatening and harassing me for several days because I would not give him the information. I told him *I* would investigate; *I* would purge the board if I found anything; but that *he* had no right to make such demands. Sprint is not the only offender. US Telecom in Cedar Rapids, IA is another bunch that makes up the rules as they go along. Their thing is, if they do not like what you say on the phone, they refuse to extend *paid* calls! I kid you not. They block all calls on their network terminating at the phone number in Chicago of a BBS which they suspect of being a phreak hive. So as a BBS user, I sign up with US Telecom for long distance, only to find after the fact that I cannot call certain BBS' if the Cedar Rapids gang has not approved. You can't do it this way! AT&T takes the good with the bad. They do prosecute for theft of service, as they rightly should; as as Sprint and others should do. But AT&T takes the concept of universal service and the importance of service availability quite seriously. They won't ever chop off innocent customers just to spite someone else. And I might add that if your AT&T card is ever compromised for any reason, if you call them immediatly -- 24 hours per day -- they will kill the card on the spot AND issue you a new pin within three or four hours. That is how serious they are about keeping service available to their customers at all times. AT&T is running some ads in Chicago right now which say it all: "You've tried all the rest -- now come back home to the best."

Not so with ISDN and SS7, anymore. But, for simplicity, let us stick with the here and now. Office Tone Plant ------ ---------- Stepper in phase(when it feels good) XBar1 in phase XBar5 in phase ESS1 not in phase ESS5 not in phase DMS100 not in phase Rolm PBX lucky to get anything! Where 'in phase' indicates the audible ringback tone plant is always in phase with the ring plant; when you hear ringback signal, the distant phone is ringing at the same instant. 'Out of phase' means that the distant ring plant may or may not be in phase with the audible ringback--there are no guarantees here. Steppers sent the same Holzer-Cabot ring plant back to you as they sent to the called phone, hence you KNEW they were in phase. #1 and #5 crossbars had tone plant for signalling and a separate ring plant for ringing called phones (#1s sounded neater). ESS changed all this, probably to distribute the load over the tone plant more evenly. It was not an infrequent occurrence on a stepper that the dial tone frequency would sag for a few seconds when too many people requested dial tone simultaneously :> In any case, the ring cycle calls for 2 seconds of plant interspersed with 4 seconds of pause. Consider the following scenario: a caller places a local call (to eliminate the vagaries of the long distance network for the moment). The instant the distant office connects, it places ring plant on the line, ringing the distant phone--2 seconds. Then two seconds of pause, and the audible ringback begins for 2 seconds. Immediately after the audible ringback ends, the ring plant begins on the distant end again. Now, no matter how many rings one extrapolates to from here on out, if the caller hangs up after X rings the distant phone will have rung X+1 times.

Isn't there some sort of tariff that requires RBOCs not to refuse to install residential service in various places where it might be more expensive than the normal installation? What grounds does NJ Bell give for refusing to install normal service? This sounds like a pretty poor deal; I would have to be *very* satisfied with my employer to agree to something like this, since it sounds like the potential to screw the consumer is very high.

Berch mcb@tis.llnl.gov / uunet!tis.llnl.gov!mcb [Moderator's Note: There is indeed a tariff which says the local Bell cannot refuse to provide service to any QUALIFIED subscriber. A qualified subscriber is any person who has exhibited an *ability* and *willingness* to pay for the service. The correspondent should contact the local telco office, and order service. He'll need to meet any reasonable credit requirements they may impose. If telco says they will not install service, then he should immediatly ask to speak with the manager. He should advise the manager that he does not wish to be placed in a position where he must appeal to the Chairman's Office, but he will do so if the manager is unable to arrange the installation promptly. The next step would be to appeal to the Chairman, then file a formal complaint with the appropriate utility regulators. They know the rules, as does the Chairman and most likely the manager. He will wind up getting local service from the telco; from there, getting AT&T on the line is a breeze. Actually, when his complaint hits the regulators, he will get a call back from the Chairman's office. In truth, it will be a highly placed flunkie authorized to respond in the Chairman's name.

Generally, when you dial 411, call supervision is passed to the called party (411).

(Hokey) Review of Article: ATT LD Network Risk Management (John Croll) ---------------------------------------------------------------------- Date: Tue, 18 Jul 89 02:02:53 EDT From: TELECOM Moderator Subject: When You Run Out of Pairs The discussion in [Telecom Digest] in recent issues regarding the scarcity of pairs has been interesting, and brings to mind a problem which is chronically popping up in older urban areas like Chicago: the lack of pairs between the central office and each premise. I've experienced both a scarcity of house pairs and a scarcity of central office pairs in the past, and it is interesting watching the installer scrape together a working pair from a selection of three or four wires not in use in the junction box. In the late 1920's and early 1930's, many high rise buildings (six or more stories) were constructed which operated as 'apartment-hotels'. They had front desk, switchboard, and maid service, among other amenities. In those days not as many people had their own private phone line. Typically, in a building twenty stories tall, there would be a dozen apartments per floor, or about 240-275 units in all. Each unit had a phone through the switchboard, as did the administrative offices. So the switchboard would typically be a two or three position cord board, serving 250-275 'stations' or extension phones; all manual switching of course. Under the accepted rule of thumb that ten percent of the subscribers (tenants, in this case) maximum would be on the phone at any given time, and that some of these would be local, from one apartment to another, typically there would be only 20-25 central office trunks coming in, to handle all incoming and outgoing traffic through the board at the front desk. In the building I lived in from 1967-1974, the switchboard had 26 trunk lines in rotary hunt, from Dorchester 3-7500 up to 7525. We also had ten 'extensions' from the board at University of Chicago, where we were Ext. 4100 --> 4109 also in rotary hunt for anyone dialing from a campus phone. Now there were perhaps 3000 such buildings in Chicago at one time; there were two others like this on my block alone. Sometime in the early to middle seventies, the economics of running older high rise apartment buildings was such that the owners of the building decided to close the front desk and switchboard. If the tenants wanted phones, let them get it direct from Illinois Bell. As more and more buildings chose to pull the boards out, these posed considerable problems for Bell in getting at least one pair to each person in the building. Generally the buildings had an IT, or inside terminal block somewhere near the switchboard where all the central office lines came in. From the board to the basement would be the (usually) several hundred pairs needed to bring each phone to the board. From the basement, these house pairs would typically run up through conduits to each floor, where they would open up on a smaller terminal block of maybe twenty pairs each. Let's say the apartment building had twelve apartments per floor; every apartment would have two pairs to the local box with one pair actually wired to a house pair coming into the box and the second pair just loose. Of the twenty pairs that came up through the conduit to that floor, twelve would in fact be specifically dedicated, or wired, one to each apartment on the floor. The remaining eight pairs would be multipled to the floor above and below. The end result would be a pair for every apartment, and maybe 100-150 extra pairs which could be manipulated throughout the building by tying any one of the extra pairs to the second pair for a given apartment. If necessary, the installer could open up a line at one place and tie down the multiple on the next floor, etc. The only problem then was the bottleneck *coming into the building*. Only maybe fifty pairs in all, considering the board had (like ours) around twenty five central office lines; a few direct lines to long distance if the board was big/busy enough, and maybe a pair or two to Western Union. If the building had Muzak, or Western Union Clock Service, or a telegram machine, then those each took a pair, etc. When the switchboards were pulled out, suddenly telco had to find enough pairs on the pole or in the street to bring a line (or two) into the building for everyone. This stretched things pretty thin for a few years, and in older areas where a lot of these buildings still stand, you can go into any building on the block; go to the big, humongous old fashioned wooden terminal box in the basement and get the dial tone from everyone on the block! In theory, when one person moves out somewhere in the vicinity, the phone man goes to *their basement* and opens up the pair, then goes to the place where a new subscriber wants service and attaches the multiple there. But people have moved into an apartment, plugged their phone into the jack, gotten dial tone and assumed they were connected only to later on hear someone talking on 'their' line who was actually down the street and across the alley somewhere. Other times telco has insisted the service was working, and the new subscriber was equally insistent that the line was dead. Phone man comes on scene, goes to the basement, fiddles around awhile, gets no where, goes out and climbs pole for awhile, comes back to basement and still dead pair, etc. Using a good pair to call the test board, they finally scrounge up one wire here and one wire there to make a pair for the bewildered customer, who *does* have two perfectly good pairs in his apartment. BEWARE THE INVASION OF THE PAIR-SNATCHERS! Even the most ignorant installer, if he hears dial tone on a pair will leave it alone and assume it belongs to someone in the building. But sometimes the pairs are incorrectly labled, or not labled at all. I have two lines here. One day looking out my window I saw a phone man on the pole in the alley. Two minutes later, my first line is dead. I called repair immediatly, and had a young lady sass me back and tell me it was 'impossible' that the guy on the pole had messed me up. I finally convinced her supervisor to at least call the guy on the pole and have him reconsider what he had done. There are some installers however who wish to avoid extra work for themselves and they will 'accidentally' snatch a working house pair from someone else, figuring it is just as easy for that person to call repair service and complain about their phone not working as it is for them to keep searching and ringing out (or sounding) pairs until they find a good *idle* one for themselves. In these older buildings, the house pairs are now sixty years old, and with faded tags written on by phone men who have long since departed this life; so it does get hairy at times. THE LADY INSTALLER COMES TO VISIT (OR, SHE MEANT WELL, I'M SURE...) About ten years ago, lady telephone installer comes to the door. Very concientous young lady that she is, she carefully holds up her ID badge and asks me to let her in the basement to work on the big box. "I am to turn on the phone in apartment 902", she beams at me. In the basement, with the covers off the terminal box she looks at this spaghetti-like mound of wire and said, "my gracious! I wonder how I will find apartment 902". I told her, you might go to 902 *first*, and see if it -is- working already. If not, put your sounder on the line up there. Then, check the box in the hall on the ninth floor and listen for your sounder. If you hear it, take note of the numbers written on the little strip of wood next to the screw terminals and then come back down here and find the same numbers on the screw terminals at this end. "Oh, do you think that would work?" Yes ma'm, I do. Sure enough, she was back five minutes later, to tell me the box on the ninth floor said HP206. I told her, now why don't you look for house pair 206 in this box. We found it, and she heard her sounder over the wire and decided 'this must be it'.... She looked puzzled and said well now we have to get the line from our office. Brilliant deduction, lady... I told her her order ticket said Rogers Park Cable 97, Pair 34 was assigned to this customer. By default, the entire terminal box in our basement is Rogers cable 97. It shows up across the street also, but that is beside the point. I told her you start in the upper left hand corner of the box and count down pair by pair. The first number is 18, so count from 18 to 34, down one row, then start at the top of the next row. Stop when you reach 34. She found it eventually, and jumped it to house pair 206. I had to feel sorry for the lady. She had only been working for Bell for a short time, and had probably never done anything in a large high rise building like that before. She even started to leave *without going back up to 902 to get her sounder and replace the cover on the modular box in the apartment*!! As I was in need of a line sounder at the time myself, I should have kept my mouth shut, but I knew she would get bawled out if she had lost it. In the past decade, Illinois Bell has added quite a bit of additional cable, so the shortages and pair snatchings are not as severe as they were, but in some older buildings, particularly when there are two or three on the same street, there is still a lot of 'fun and games' when someone wants a second or third line installed.

One of the articles is about the ATT phone system, and it talks some about the last year's disaster at the Hinsdale telephone switching center. The article is primarily about how ATT manages its long distance network to minimize catastrophes, large and small. MCI and US Sprint are mentioned only briefly, because, as the article says, their LD networks are not as large or extensive as ATT's, and they have not adopted the flexible network architecture ATT now uses. Although the other articles in this issue are not about telephony, they are equally interesting. There are two articles about risk analysis techniques, and about their limits and pitfalls, and there are articles about aircraft aging, the Savannah River nuclear weapons plant, the Challanger explosion, and the Bhopal disaster. This issue is a good introduction to managing engineering risk.

Another item of interest: the alternative carriers have really let the small-town user down. Several years ago, as the result of pressure from MCI, along with others, the California PUC passed an edict that all Pac*Bell exchanges would have to be fully equal access compliant by the end of 1987. This sent Pac*Bell scrambling to replace ancient SXS switches with DMS and caused them to glue CONTAC onto their remaining #5 crossbar war wagons. As a result of all this, Pac*Bell probably has the highest percentage of equal access exchanges in the country, but so what? If you go out of metropolitan areas, like Weed, or Baker, or Los Banos, you will find equal access telephones with no carriers available except for Mother. Why? Well, Sprint, MCI, Telesphere, and all the rest don't *really* want to bother with sleepy little out-of-the-way communities. Since only Mother has to provide universal service, why should they spend all that money just so a few people can use their service. No, my friends, what they were really after was to have the metro areas have universal equal access so that they could maximize their penetration in areas that required minimal cost. Someone from Weed let me know when someone other than AT&T provides feature group D long distance from up there. I'm not holding my breath. -- John Higdon | P. O.

Of course, turning off authorization on suspicion of unauthorized use doesn't make any sense, either. If Sprint really suspected that the card had fallen into evil hands, it would be better to let a call go through and then investigate and possibly identify the culprit. But more important, it's this cavalier attitude that puts AT&T in a class by itself. Phone service in this country has been reliable enough that we have all taken it for granted. We *rely* on it. Over recent years, Sprint, MCI, Telesphere, etc., ad nauseum, have demonstrated that they consider telephone service in the same category as cable television: nice when it works, but not really essential. After all, as one Sprint rep told me once, "If it doesn't work, you can always use AT&T." Customers' loyalty to the "OCCs" is truly amazing. If your local operating company took the same attitude in providing dial tone that Sprint et al take in providing long distance service, your life and property would be at serious risk. Furthermore, the OCCs act as though they are doing you a favor by completing a call. "If you play by our screwy rules, and kiss it up just right, we'll put your call through if it's convenient." While it may sound like commercial copy, AT&T acts as though every single call is essential to their business. Not a bad attitude from a company who just a few years ago was indeed the only game in town. -- John Higdon | P. O.

If you Current reregulation attempts by Pac*Bell would extend the 8 mile radius to 12 miles. This would (hopefully) correct some of the gross inequities that exist in the south Bay Area. For example, Campbell is a community surrounded on all sides by San Jose, yet is has its own exchange. San Jose itself is divided into three zones. All "San Jose" prefixes are local to each other, but each zone has a different local calling area, and this is where the inequities lie. Campbell<>Zone 1 is toll, and yet there are many San Jose addresses in the "Campbell" exchange. Zone 1 is the east side, but from there it's a local call to Zone 2 telephones that are located far west of the Campbell exchange all the way to the Cupertino hills! Depending on where you draw your route, a five mile call can be toll and a thirty mile call can be local. Most of this is due to the fact that the zones have very irregular shapes that resemble political gerrymandering (coincidental?) and have little to do with geographical realities. -- John Higdon | P.

Woodbury" Subject: Local Area Calls In Research Triangle Area, NC Research Triangle Area of North Carolina is the area around the cities of Durham, Chapel Hill and Raleigh. Durham is served by GTE-South, Raleigh and Chapel Hill are Southern Bell. Research Triangle Park is in the GTE domain (Durham County). Enough geography. Generally, GTE provides Durham with flat rate service that includes: Durham, RTP, Butner and Creedmore, GTE provides RTP with Business service (flat rate, mostly) that includes: Durham, Raleigh, and Chapel Hill. SBT provides Raleigh flat rate service to: Raleigh (and suburbs to west, south and north - east is Durham), and RTP. Chapel Hill gets Chapel Hill and Carrboro. Given this, lots of businesses like RTP exchange services, but FTX is not available due to the strange politics of the RTP. (They have to be in the RTP or certain specific areas near it to qualify.) Many businesses in Chapel Hill (about 20 miles from Durham, 32 from Raleigh) got FTX lines from Durham (note past tense). There have been calls (for many years) to extend "local area" service between Durham and Chapel Hill, but this was prevented by the PUC's unwillingness to force GTE and SBT into bed together. Finally, they did make a "Tri-wide" calling plan available. It is basically just a measured rate service that lets consumers in each city call all the others. This, in effect, makes each calling area in the Triangle look like the descriptions I have seen of Boston. There is an unmeasured local area, and then there is a measured service extended area, and then there is "Long Distance" (there are the usual disctinctions about intra-LATA, and inter-LATA and the carrier wars). Tri-wide also changed is so that you don't need 1+ to call in the extended calling areas. When Tri-wide was announced, it was very poorly handled, most people in Durham got it by default (you had an option to refuse it, but they did NOT make this very well known). Chapel Hill and Raleigh implemented it about a month later and the users had to request it. Also, Raleigh and Chapel Hill (SBT) users can get more extensions to other areas (e.g. Chapel Hill-Hillsboro, or Raleigh-Smithfield) at additional cost. The Duke University TelCom system (independent of GTE and SBT) chose to not participate, thus there is still 1+ service from Duke to Raleigh or Chapel Hill.

Tamkin) In the past two weeks I've submitted four articles to the Digest at telecom@eecs.nwu.edu; one bounced after ten days and three are in limbo. For all the readers' electronic viewing pleasure, here they come again in one swell foop, plus a fifth I was going to submit the day I first tried mailing this compendium. I don't save Digest issues, so I cannot say who originally brought what up nor quote exact phrasing. My original submissions did, but once I had responded I deleted my copies of the inspirational texts to which I was replying. If saying that "someone spoke about a situation" without precise citation offends you, please skip this article in its entirety. 1. The moderator and the moderator emeritus were discussing the pros and cons of telco-controlled Speed Dialing and saved numbers in the memory of one's own telephone instrument. For my purposes the latter is much more useful: no setup fee, no monthly fees, larger memory capacity in most cases, and the ability to program partial numbers. If you frequently call different extensions of a business you can preprogram their common digits; if you live near an area code border you can preprogram 1+NPA to spare your fingers the labor on all your calls across the line. Try doing that with Speed Dialing. 2. The moderator stated that Dial-an-Atheist has been available since 1979 at 312-506-9200. Until 1983 all prefixes in area code 312 were NNX. Either Dial-an-Atheist doesn't date back as far as 1979 or it has had a phone number change over the course of its history. 3. Said moderator commented that, quite the opposite of David Gast's experiences in Los Angeles, published telephone numbers in metropolitan Kansas City are available from Directory Assistance at either +1 816 555 1212 or +1 913 555 1212, regardless of whether the number you request is located in Missouri or Kansas. After 708 is split from 312 this November, it appears that both +1 312 555 1212 and +1 708 555 1212 will ring at 10 S. Canal Street in area code 312, where Directory Assistance for both area codes will be handled in one place. 4. I believe it was Ilya Goldberg who asked about the assignment of default long distance carriers to telco-owned pay phones. In the parts of metropolitan Chicago served by Illinois Bell, the owner of the premises on which the public coin phone is located selects the default long distance carrier. One very curious result is that Illinois Bell pay phones outside Illinois Bell's own corporate headquarters are assigned to MCI rather than to IBT's pre-divestiture parent. 5. Finally, I had believed that 708 was to be the first geographically discontiguous NPA in the North American Numbering Plan. The city of Chicago has four cartographic holes, subscribers in two of which having service on suburban telephone prefixes. As a result, area code 708 will be in three pieces: the bulk outside the perimeter of the city of Chicago and the two islands of 708 that will be surrounded by 312. (To continue the metaphor, I live along the strait that separates those two islands. That makes it sound as though I live in a houseboat, doesn't it?) But I remembered that Liberty Island and Ellis Island are politically part of the borough of Manhattan and the County of New York, even though they are on the far side of Staten Island from Manhattan Island itself. If telephone numbers on Liberty Island and Ellis Island are in area code 212, reflecting political boundaries, instead of area code 718 to reflect geographical intuition, then 212 has been a discontiguous NPA ever since the 212/718 split back in 1983 or 1984.

Automatic callback to the last connection; call identification in the form of distinctive ringing with up to three distinct phone numbers per line; call blocking of unwanted calls and home intercom are the features being added. They have been offered on a trial basis in the Hyde Park office for the past several months. They will be available in most south side exchanges beginning in October, and throughout other areas of the city early in 1990. The suburbs will be equipped during the summer of 1990. They are *not* offering calling party ID at this time. These additional features are being offered at an average price of $5 each per month. A discount will be given to people taking all of them. In the case of distinctive ringing (what they are calling call identification), the cost of one additional number parked on your line is $4.85 per month. The cost of two additional numbers is $8.90. If you wish, you can also have calling cards issued on those numbers to provide a sort of internal billing and accounting of long distance calls by family members, etc. Patrick Townson ------------------------------ Date: Wed, 19 Jul 89 1:24:03 CDT From: TELECOM Moderator Subject: Archives Final Day!

Date: 19 Jul 89 01:34:23 GMT Organization: The Hole in the Wall Hollywood CA U.S.A. It appears that British Telecom is changing the London area code from 01 to 071 for central London and 081 for Outer London. I read this in the July 1st edition of the New Scientist - not exactly a reliable source of Telco info. But I have read nothing here about it yet, and am sure some of would like to know. I am also sure that I will be flamed from the UK for not getting my facts right. So here are the facts as I have divined them from California: The change is to 2 digits if you consider the 0 digit is a leader as the 1 digit is in the U.S. i.e. 1(213). Paraphrased here is the New Scientist article: There are currently 4 million subscribers in the London (01) area code. British Telecom says the practical limit is 4.5 Million which will be reached some time in late 1990. Central London currently has 1.5 Million subscribers. Outer London has 2.5 Million. Note that the standard London phone number is a 7 digit number, just like the U.S. a three digit CO code and a four digit subscriber suffix. i.e. 353-4622. The Changeover will be May 6 1990. The master plan they say is to have all major cities with a 3 digit (0NN) area code. The New Scientist moans and groans about the inconvenience and futility of it all. Alas, the usual moaning and groaning of people who wake to find they have a new area code. And a final question for all amateur spooks and freaks of old: What exactly was the FEDeral manual exchange in London during the sixties? Does it still exist?

This is incorrect. According to my own experience (I LIVE in San Francisco! (;-) ), and the Pac Bell phone directory, all calls from SF prefixes/areas to other areas of SF are zone 1 == no charge.

Sure, adding zone 2 to the no charge calling area would be nice for those that call those areas a lot, and would likewise be a bummer for those who don't (they get to pay the extra $$ for getting a calling area they don't use). But who knows if this really makes a difference to the average caller? The usefulness of such a move (from a consumer point-of-view) would depend on how much more the extra zone would cost, and how many zone 2 calls are made by how many people. If I remember correctly, the proposal you cite plans to do a lot more than expand free calling areas. I believe it also hopes to give standard subscribers more services (such as touch tone for FREE!

However, there is yet another possible method to implement a "wiretap" (reason for quotes will become apparent) that is totally impossible to detect, because it does not even cause the very-slight changes Mr. Lippman discussed. On any line served by an all-digital switch, all line signals pass through a digital cross-connect device which is essentially a large block of random access memory (RAM). Connections through this device are made by simply copying the digital image of the line audio signals from one RAM location (address) to another. It does not require a degree in computer science to see that the digitized audio may be copied just as easily to a second location, thus allowing completely undetectable monitoring of the line in question. I do not *know* that software to perform this function exists. But I suspect that it would only take fifteen minutes for a #5ESS-trained programmer to write it... A wiretap without any wire!

Well, we recently received our equal access ballots in Dawsonville, GA (404-265) along with other customers of "Standard Telephone" (an independent but all-digital telco in northeast GA). We have *five* choices: "AT&T - The Right Choice" (no kidding -- that's what it says!) MCI Sprint Southernnet Teleconnect(? ballot's at home) The ballot also has the three-digit access codes for each company, but with NO explanation of what they might be good for. Some fine print at the bottom reads (paraphrased) "some of these carriers bill you separately, unless they have made billing arrangements with us." Once again, no indication of who may have made such arrangements (besides AT&T, who has and will continue to handle our long-distance calls). 404-265 *might* have 2000 subscribers; I seem to remember reading that Standard has 15000 total subscribers in six exchanges. Dawsonville is about 60 miles from Atlanta, 30 miles into the long-distance-to-Atlanta desert, and the fastest-growing of Standard's exchanges. (I could relate a few stories about when we used to call it "Sub-Standard," but they've really grown & grown up in the last few years. An ESS in every exchange, and all that.)

That's interesting. I would think that since the offenders had broken into the PBX to make the calls, Sprint wouldn't be at fault, and wouldn't pay. Whomever manages that PBX should shell out! I guess it was thus a goodwill gesture. This is also interesting to me, considering the war I had with Sprint trying to get them to credit us for $16 in calls someone had made to one of our *outgoing* PBX trunks without a PIN number, without true authorization. My brian-dead Sprint rep said that it is normal practice for their operators (and ``everyone else does it'') to just take a phone number and charge a call to it. No ringing the 3rd number, no nothing. For if they had done this in this case, the number would never have answered (incoming numbers don't get answered by our switch.) Not to just badmouth Sprint or anything; I think they have a nice network and decent prices. But the reps in my area are just too much (really too little ...), and they didn't pay enough attention to our needs for the $14K per month we were giving them. ...ben ---- ben ullrich consider my words disclaimed,if you consider them at all sybase, inc., emeryville, ca +1 (415) 596 - 3500 this space for rent ben@sybase.com {pyramid,pacbell,sun,lll-tis}!sybase!ben ------------------------------ Date: 20-JUL-1989 02:14:47.16 From: "DOUGLAS SCOTT REUBEN)" Subject: re: Sprint calling card fraud Hi all! Since we are seem to be on the topic of US Sprint and the way they deal with calling card fraud, I thought I'd mention a similar experience I had with them. I was a US Telecom "access port" customer. This was before the days of "US Sprint", and we didn't have Equal Access, nor did I want US Tel. as my 1+ company. I signed up so I could use their service when their rates were less than AT&T's, and would use the 950-1033 access port to call via US Tel. I used it for about 5 months, and finally realized that there was so little difference (even 'back' then, 1986) between US Tel and AT&T that I rarely used them. A little while later, I tried using US Tel, yet when I entered my code, I got a message "Your long distance service has been temporarily suspended." So I called Customer Service (a misnomer, I know...:-) ), waited the mandatory 30 minutes on hold, got the usual "It's all your fault" customer service rep, who said "Well, if you didn't use us for 4 months how should WE know that you still were our customer?" (Well, like, just MAYBE you could have used that great network of yours and call me from wherever you are and ASK me if I still wanted US Tel, see??!?) So they re-issue the code to me, and I used it maybe 3 times. Then I get a call from them, saying that "We have turned of your service since we have detected code abuse". So I asked, "Well, to where?" They didn't know. I asked "how many calls?" Same answer. I asked "How *much* is the bill?" No idea. But they *did* know someone was using my code! So I told them to call me back when they knew something more definite, and in the meantime they turned off my code again. (no big loss...) I got a call from them 3 days later saying "Since you didn't use your code number for 4 months, we thought that maybe someone found your card and was making illegal calls..." I asked, "Well, how many were there?" And the guy checks and says "Uhhh..I think 3..." Hmmm...wow...3 calls...fraudulent use! Geee...sounds like a great method for detecting little kiddie hackers to me! (Actually, a great way to get rid of customers, which they did indeed!) Now, 3 years later, I use my AT&T card over 32 times in one hour. This triggers off a "high roller" trouble card (?) at the SNET office back in CT. (I was in California). They called my machine, told me that there was trouble, told me they'd have the numbers that were being called in 24 hours, and told me they would cancel the card until I called back. So I call back on a SATURDAY, get someone at the emergency repair unit, and after explaining it to him for 2 minutes, he understands completely (he was the one who told me they call people who use the "#" sign too frequently "high rollers".) He told me that my SNET/ATT card would be back in service in CT almost immediately, and throughout North America within 3 hours. Now you can draw whatever conclsusions you want from this, however, you may want to note that I spent maybe 3 hours in total dealing with US Tel, while I called COLLECT back to CT and had SNET rectify the problem with my AT&T card in 5 minutes. And they did indeed take the matter quite seriously. They didn't ask me why I made the calls, or have some lame "It's not our fault" excuse. Rather, they handled the matter as if they were embarrassed to bother me so much, and apologized for having to cut off my Calling Card for a while. This is not to say that all my experiences with AT&T have been quite as pleasant, as they have been a bit sloppy in one or two cases. But AT&T has always taken the approach that "the customer is always right", while after plenty of other bad experiences with Sprint, US Tel, and Allnet, I am convinced, that despite whatever extra-perky/cheerful/etc. customer service reps. they have hired since I subscribed to them, their attitude is more like "..and why should WE care about you, anyhow?". And I *don't* work for or in any way have anything to do with AT&T other than being a customer of theirs, so please don't use that as an excuse to flame me! :-) Thanks! -Doug dreuben@eagle.wesleyan.edu dreuben%eagle.weslyn@wesleyan.bitnet (and just plain old "dreuben" to locals!:-) ) ------------------------------ From: John DeArmond Subject: Re: Wardialers Date: 19 Jul 89 23:09:13 GMT Reply-To: John DeArmond Organization: Sales Technologies Inc., "The Procedure IS the product" In article zygot!john@apple.com (John Higdon) writes: > >But more important, it's this cavalier attitude that puts AT&T in a >class by itself.

John, I have to agree with you 100%. I've always had a love-hate with AT&T (Damn, they sure got mad when they caught me reselling residential service via a homemade switch and wires strung thru ditches :-) Before hissoner got involved, they could be the most rude, most incosiderate, most hateful people imaginable. I remember being stunned the first time I had an AT&T operator THANK me for using the service. Or actually having time for directory assistance. And none of mere civilians will ever be able to imagine what we've lost by having Bell Labs become commercial. On the other hand, I could call "the phone company" when I had a problem. I didn't have to worry about whether it was in-house wiring or network wiring. It all got taken care of. And I could rely absolutely on getting a dial tone AND getting reliable long distance service merely by dialing 1+ or 0+. No AOS, no COCOTS or any of these other cuss words. Yeah, yeah, rates have come down but subscriber rates, especially business have more than risen to compensate for the small users. Of course, big business got the deals they always wanted. Perhaps the solution is simply to speak with our pocketbooks. Enough of us should probably use sprint or mci (flush the others) so that they can stick around and provide competition. Other than that, let's make AT&T "the phone company" again. A little lobbying in congress to keep them and the FCC out of AT&T's hair and things will be complete.

Who's to say how this influenced the results? From what I understand, the Bell study was the reason that the current 7-digit system was set up in the first place. There was no American parochialism before then, because there was no standard telephone number length or format in use at the time; there was a only mish-mash of different setups. From what I remember reading, the study tested people to discover the longest number-length that could be easily remembered, and the best format for such numbers. The optimal answer they came up with was 7 digits, arranged in a 3-4 split. (Correct me if I'm wrong, you other Telecom readers who remember this better.) >They [Germany] will never run out of numbers (unlike the US). Once NXX area codes are implemented in a few years, the NANP will have on the order of 5 * 10^9 possible numbers.

I don't see how you can use area code splitting as an example that proves the superiority of variable-length systems over fixed-length ones. It seems to me that it would be just as annoying to have my number changed from (say) 369.56.78 to 73.69.56.78 as it would be to have my number changed from (say) 617-369-5678 to 508-369-5678. You still have to get all the stationery reprinted, etc. In fact, I could argue that an area code split can be *less* traumatic overall. Consider that when Paris went to 8 digits, *everybody* in Paris had their number changed. Now consider that when New York City split 718 off from 212, *only* the people consigned to the new code had their numbers changed. The denizens of Manhattan and the Bronx (which continue to be 212) weren't inconvenienced at all. Fixed-length numbers have other advantages as well. The well-known number format is an easily-memorized template, and makes it extremely easy to notice dropped digits and such, since the result is a malformed number. Also, they can allow telco switching equipment to be used more efficiently because, once the first few digits have been entered, the length of the rest of the number can generally be calculated (excepting international calls, of course!). This means that the switching equipment doesn't have to waste time by constantly asking itself "is he done dialing?" after each and every digit is sent; it can just wait until all the digits are in.

And yes, they are in a different area code (408 vs. 415), but so is Sunnyvale which is Zone 2. I am also the proud purchaser of a "CALL BONUS Community Plan" which provides reduced rates on calls to an island consisting of about a third of San Francisco. This plan has no effect on calls to other parts of San Francisco nor to other parts of my LATA. Calls to the island are subject to a 30% discount (as well as to time-of-day discounts); the remaining charges for calls to the island are subject to a credit of $14.90 (being twice the $7.45 which I pay for this plan). Thus Pacific Belle shows a preference for a sure-thing monthly charge over the possibility that I'll call my ladyfriend in San Francisco somewhat less frequently. No time of day restrictions on this rate, but I'll bet many of the people who use this residence service scheme do so during off-peak hours. They even offer a double size version, providing $30 of credit for a $15 monthly charge.

PT] I once got a call back from a pbx I had recently installed, they couldn't dial a particular NXX in a neighbouring NPA. They had automatic routing and an 'FX' that went to the same neighbouring NPA. I checked my programming remotely and found it entered correctly. I tried it myself (again remotely). the call didn't proceed when dialed with a preceeding '1'. This NXX was listed in the phone book as belonging to a foreign exchange, one needing a leading one (and a toll call). The telephone company had been doing rebuild in the area recently and twice before several trunks had been reversed, so I reported the trouble to Bell. What ensued was a very entertaining series of conference calls with CO people of different levels until finally I had been handed off to the very craftsmen who maintained the office serving this 'FX' line. He checked my statements and confirmed that that dialing arrangement was indeed the programmed routing for that exchange. It turned out that this entire switch had been allowing seven digit dialing (and consequently no toll!) to that one particular NXX within the same office as other 'toll' NXX's, contrary to the published tariff's (and the phone book). I was told that it had been that way for some matter of months.

This unit has two trunk lines and 12 extensions, with various PBX features. Two extensions ring by default for the two trunks, but 'call forwarding' allows the trunks to ring on whatever two extensions you designate. There is common audible of course, and universal pickup by dialing '7'. I used one of these for about three years before I got my Starline installation.

Prefixing a call with | 10288 does nothing except force the call to be routed via AT&T. | It does not incur extra charges other than whatever slight | difference there is between AT&T rates to the point in question | and whatever other carrier was being used. If you dial an intra- | lata call (a call within your own town, for example) using 10288 | as the leading code, it is likely the call will be rejected and | you will have to dial over again. I've tried this, and at least | here in Chicago, dialing 10288 followed by a seven digit (or ten digit, | but within IBT's lata) number and a recording says the call cannot be | completed as dialed. Whether or not you get 'cleaner' lines by | forcing your call over AT&T is a very subjective matter. But in | and of itself, 10288 is a way of routing long distance calls -- | not a special feature to insure clean lines at an added cost. PT] Wrong, Wrong, Wrong. Just tried an experiment.. from one of my 12 lines, at home, 512/829-1028, I dialed pro-party, my bbs at 512/829-1027 with the followwing variations: AT&T 10288-829-1027 (connect) MCI 10222-829-1027 (connect) Sprint 10333-829-1027 (connect) Westel 10085-829-1027 (connect) National 10737-829-1027 (connect) All of the above 10XXX-1-829-1027 (It is not necessary to dial a 1 recording) All of the above 10XXX-512-829-1027 (It is not necessary to dial the areacode first.

Westel 950-0085pp829-1027ppPIN (connect) Westel 950-0085pp512-829-1027ppPin (connect) Also, Inter-Lata Calls (San Antonio -> New Braunfels) can be completed using 10xxx codes (and are billed at a lower rate than SW Bell inter- lata long distance calls.. though its still cheaper for me to go into my car and call New Braunfels because its a local call from my cellular and the LD charges are more than the cellular airtime). SW Bell is aware of the inter-lata problem.. I saw one of their public notice ads in the paper saying that though you wern't supposed to be able to do it you could and that they were petitioning the PUC to allow them to block inter-lata 10xxx dialing. I do not know if they are aware of the 10xxx-local number situation.. it sounds like a bug in their switch. It does raise some interesting questions about pay phone calls. My average local payphone call is less than 5 minutes, so at $.053/minute short 10xxx calls would be cheeper than a $.25 coin call. (Dosn't MCI offer a local call from payphone program using their calling card?). ------------------------------ From: "Glen M.

Presumably they use something else (like 9?) as an area code introducer. Closer to home, Australian area codes all start with a 0 which is not dialled when you come in from overseas. However, some of the area codes start with two 0s, e.g. Hobart is 002, so from the USA you'd dial something like: 011 61 02 nx xxxx to get a number in Hobart. If you leave off the 0 you'd get a number in Sydney: 011 61 2 nx xxxx But then local numbers in Sydney can be 5, 6 or 7 digits, so you might end up not dialling a full number. ------------------------------ From: David Lewis Subject: Re: How Do I Obtain a Phone Calling Card?

The calling card databases were one of several types of facilities (particularly "Class 4" tandem switches) which were in effect "shared" between the BOCs and AT&T Long Lines, which couldn't be split. (I can't recall offhand what the name of the AT&T Calling Card DB is called; I'm sure some willing Bell Labs soul could help me out....) For this reason, at divestiture the BOCs were in essence granted a waiver to allow them to continue to use the AT&T calling card verification databases until they were able to develop and deploy their own systems. They've developed them, using a database system called LIDB (Line Information DataBase), but deployment is being held up in legal maneuverings, the extent of which I can't recall offhand. Probably something to do with call setup times, like 800 DBS. I believe there's a time limit on the waiver, but I suspect if the RBOCs went to Judge Green with a case that they've developed a system but have been unable to deploy it because of legal challenges, the waiver would be extended. Disclaimer: I don't work on LIDB, so I don't really know any of this. -- David G Lewis ...!bellcore!nvuxr!deej "If this is paradise, I wish I had a lawnmower." ------------------------------ Date: Thu, 20 Jul 89 16:27:57 pdt From: John Opalko Subject: Re: Unusual Recorded Messages Organization: McCaw Cellular Communications, Inc., Seattle In you write: >If you know of unusual or different recorded announcements in your community, >please send them along to the Digest.
