    Hello party!

    This is Scratchy Bernay in Orchards talking through a tandem line in northwest Or-e-gone. Uh, my volume is probably terrible, but anyway you have the famous voice of the Public Branch Coordinator of the Public State of Washington. And if you don't know what the word "public" means, cram it.

    I have to go! Goodb

  2. Pancakes and a Mc1035 on the way home from work at 2130. How can you not be loving that?

  3. Evan: "The whole concept of CLLI codes has expanded beyond telecommunications and I understand these days even lamp posts have CLLI codes". It's true. I'll get some shots one of these days when I get my camera working again!

      I keep looking around my area (where there's still Alltel-branded equipment), and I haven't seen one yet. So I'm seriously interested!

  4. Yeah, those were the edited/narrated tapes but apparently Mark Bernay had his own hour-long rawtape capture/s on his FTP server (ftp.wideweb.com) a long time ago. I must have missed it because I personally don't remember ever seeing it over the last 10 years or so, but Thoughtphreak has a copy up on his site: http://thoughtphreaker.omghax.ca/audio/zzzzzz-side-1.flac or http://thoughtphreaker.omghax.ca/audio/zzzzzz-side-1.mp3 But that's side 1 apparently. And this one's a ZZZZZZ-lover's dream come true because it includes lots of content not included in the Doorbell posts. Unfortunately since it's a speaker-out recording the recorder's microphone also picked up a lot of extraneous noise in the room.
  5. TP: Was there ever a side 2 to the ZZZZZZ rawtape or did Mark only have that one on the FTP?

  9. Converting to XP from anything post-Vi$ta is an UPgrade as far as I'm concerned. Was the hard/SS drive on the Toshiba mounted in a removable "tray" that you access from the underside of the laptop or one of those stupid things where you have to remove the keyboard to get it? I had a couple old Toshiba laptops that had the former setup. (OP edited by scratchytcarrier: fixed the linefeed spacing that got all messed up during the forum software conversion. You're welcome.)
  10. Currently watching the end of "Diagnosis Murder". Way to rock the old Weatherstar 1 font!

  11. In Portland, 452.500 MHz (WPHZ563) is an analog E.F. Johnson LTR trunk channel operated by Silke Communications' "Fleetnet" leased-access system and is a DMS patch. Occasionally it's possible to hear it cycling between dial tone/"not" lady/off-hook/permanent signal, sometimes for days on end. I haven't done anything with it since I don't have any LTR equipment <g>
  12. This never occurred to me before. The only reason I can think of for a step office having a Pentaconta off-hook signal generator is Carolina Telephone. Carolina was part of United and they operated Pentas. I suppose they must have had an extra tone generator sitting around in CTel-land and they decided to use it, so they parked it in White Salmon. That's the simplest theory I can come up with.
  13. Another pre-1994 list. Not from Mistman but included for comparison and has lots of explanatory information. http://textfiles.com/phreak/guide.npa Received: from wumpus.brl.mil by MINTAKA.LCS.MIT.EDU id aa20654; 7 Jan 94 19:07 EST Received: by WUMPUS.BRL.MIL id aa26172; 7 Jan 94 19:00 EST Date: Fri, 7 Jan 94 19:00:01 EST From: cmoore@brl.mil Subject: guide To: telecom-request@eecs.nwu.edu, telecom-recent@LCS.MIT.EDU Message-ID: TELECOM Digest Guide to North American Area Codes ========================= November 4, 1991 ** Revised version as of 7 January 1994 ** FIRST, PLEASE TAKE NOTE THAT the information appearing herein has been placed in the public domain. It can be copied and distributed freely. While prepared for, and intended as a service to the USENET community, anyone is free to copy it and use/distribute it. Please credit TELECOM Digest, and our correspondents named herein in any republication. This guide is in several parts: 1) Numerical listing of area codes; major cities served by each or state name, where area code serves entire state or province. 2) Listing and discussion of SAC's (Special Area Codes) which do not relate to the voice telephone network or do relate to the voice network but have no specific geographical region assigned. 3) Numerical listing of prefixes in 'area code' 800 (the code used for In-WATS 'toll-free' calling) and telephone carrier which is assigned to each. 4) Numerical listing of prefixes in 'area code' 900 (the code used for value added information services) and the telephone company or IP (Information Provider) which operates each group of lines. 5) A translation table for the names of the companies involved. 6) A technical discussion of the processing of 700/800/900 calls. 7) A glossary of technical terms used throughout the guide. To ascertain the name of a community assigned to any particular prefix other than 700/800/900 -- that is to say, a 'regular' area code, simply dial the AT&T Operator at 10288-0 (or simply '00' if AT&T is your default long distance carrier. Ask the operator for the 'name-place' of the area code and prefix in question. There is no charge for this service. The persons named at the start of each item in the guide are responsible for the accuracy of the contents therein. We hope this guide to area codes in North America will be useful information for Usenetters using the phone. ============================================================================ To: comp-dcom-telecom@rutgers.edu From: dupuy@cs.columbia.edu (Alexander Dupuy) Subject: Area Code Numerical Listings Date: 13 Jan 89 22:11:51 GMT You don't need a C program to translate area codes into placenames: this script does the trick just as well, and it's easy to modify when they change: @alex [ revised Nov. 4, 1991 and later by Carl Moore ] ============================================================================== #!/bin/sh 'exec' /usr/bin/look "$1" "$0" 011 [ International Access Code ] 200 [ Reserved -

These three digit codes are also in use, although they are not, strictly speaking, 'area codes'. They are not in the chart above since I thought some of you may not want them there. If you do, then edit them in. [Some of the following information became obsolete, because 410,510,610,810,910 became geographic area codes.] 200 Local testing, used by many telcos. 410 Western Union Telegraph Company - Northeast USA 510 Western Union Telegraph Company - Eastern USA 610 Western Union Telegraph Company - Canada 700 Value Added Information Services, per individual OCC 710 Western Union Telegraph Company - Southern USA 800 In-WATS 'toll free' calling 810 Western Union Telegraph Company - Mexico 900 Mass Calling Information/Value Added Services 910 Western Union Telegraph Company - Western USA (from Chicago westward) The thing with WUTCO is, many years ago the old Bell System operated Teletype machines; what they called the TWX (or [T]ype[W]riter E[X]change. The TWX machines had their own switches, located in existing telephone central offices, but on separate equipment. About twenty years ago, a court ruling required Bell to sell its TWX service to Western Union, in a suit brought by WUTCO against AT&T. WUTCO operated the system as TWX for many years, and in the past five years has changed the name to Telex II. The Western Union central offices for Telex I (the original telex network) have always been in WUTCO offices. The central offices for Telex II (formerly AT&T's TWX) are still in Bell central offices, although they now belong to WUTCO. Is that clear? You cannot dial into those numbers. The WUTCO codes more or less match certain areas of the country, but in recent years they have been more randomly assigned. If you see a number which looks like a phone number, but has one of those leading codes, it is actually a TWX machine. When the present unassigned area codes of the conventional format have all been used, sometime around 1992-1995, area codes 210,211,310,311,400,500,511, 600,711 and 811 will be next in line for assignment. [Note as of 1993, 210 and 310 in use.] Whether or not you want to include these special numbers in the chart given in the earlier message depends on if you want strictly a listing of the *dialable* codes used by the voice network at present, or if you want to include all *assigned* codes. And while 700-800-900 are not strictly speaking area codes, my belief is they definitely should be added to the list. ========================================================================== Date: Mon, 2 Jan 89 20:30:08 EST From: scotts@bu-it.BU.EDU To: telecom@bu-it.bu.edu Subject: 800 Service As some readers of this list may not know, under Equal Access, any long-distance company can carry 1-800 traffic. Which carrier gets the call is determined (at the moment) by the NNX of the number. I.E. 1-800-528-1234 (The nation-wide number for making reservations at a Best Western Motel) is carried by AT&T. While 1-800-888-1800 is carried by MCI. The carrier must have Feature Group D presence for originating calls from the originating exchange (either direct, or through an access tandem). In the future, when CCIS becomes wide-spread, a query will be made in the database [Who gets 1-800-985-1234?] and the call will be routed appropriately. To clarify: Now the carrier is determined by the NNX. In the future, the carrier will be determined by the entire 7 digits. A similar situation exists with 900 service. Each carrier can reserve NXX-s from BellCore (the people who among a zillion other tasks are in charge of handing out prefixes and area codes). They're not cheap! To get the actual number is free (there are qualifications that I don't deal with), but to get it 'turned on' in a LATA costs you money, depending on (1) How many prefixes you're getting, (2) whether it's 800 or 900 service, (3) How many Tandems/End Offices are in the LATA. It requires a discrete amount of labor for EACH office, because EACH routing table must be modified. Of the 800 possible NXX-s, 409 are currently assigned. A long-distance carrier can get one 800 and four 900 numbers just for the paperwork. But to get more than that, you have to show that you're 70% full now, and demonstrate a real need for the capacity. I have included the entire 800-NXX to long-distance carrier translation table.

These include 700, 800, and 900. Most telephone users from the United States are quite familiar with 800 service: a number that they dial and incur NO charge (not even message units in most [all?] areas). Then there is 900 service, which is most people perceive as 'value added', i.e. you pay more for the information than for the transport of the call. These vary typically from 35 cents to a few dollars for either a timed service, or a 'as long as you like' duration-sensitive service. There are two sub-species of 900 service, AT&T and "everybody else". Finally there is 700 service, which many people remember as Alliance Teleconferencing. This is the third "canonical" SAC. With few limitations, this SAC is given over to the IEC entirely. Let's look at these in more detail: 800 service is offered by various IECs. Each NXX in the 800 SAC is assigned to a given carrier, who is responsible for assigning numbers from that block to customers, and providing 10 digit translation. When you as Joe Customer dial 1-800-222-1234 (made up number, please don't bother them) it will initiate the following sequence: 1. If you are in an Electronic Office (DMS-100, DMS-200, 1A ESS, #5 ESS) the 800-222 will be translated to "AT&T" and search for an opening in a trunk group marked for 800 origination. Should none be found, bump to step 3. 2. If you are in a non-electronic office (SXS, XB, and some flavors of ESS), it will go to the access tandem that your office 'homes' on, where 800-222 will be translated to "AT&T". [note that if at this point, the number doesn't have a translation, you will get a "lose" recording from the CO] 3. Find a trunk in a trunk group marked for 800 origination. Should none be found, give the customer a recording "Due to network congestion, your 800 call could not be completed" or die, or whatever. (Depends on phase of moon, etc.) 4. The end office will then send the following pulse-stream (in MF): KP + II + 3/10D + ST + KP + 800 222 1234 + ST (note that this is a simplification, there are some fine points of ANI spills that are beyond the scope of this article) II = 2 information digits ... typical values are: 00 normal ANI .. 10 digits follow 01 ONI line ... NPA follows 02 ANI failure ... NPA follows 3/10D = 3 or 10 digits. Either the NPA, or the entire 10 digit number. KP and ST are control tones 5. The carrier receives all of this (and probably throws the ANI into the bit bucket) and translates the 800 number to what's called a PTN, or Plant Test Number. For Example, 617-555-9111. Then, the call is routed AS IF the customer had dialed that 10 digit number. Of course, the billing data is marked as an 800 call, so the subscriber receiving th call pays the appropriate amount. 900 Service. As I mentioned earlier there are two flavors of 900 service, AT&T, and "Everybody Else". Everybody else is handled exactly as 800 service above, except the IEC will probably use the ANI information to send you a bill. (Either directly, or through your BOC, each situation governed by applicable tariffs and contractual arrangements between the IEC and the BOC) AT&T 900 is a curious monster indeed. It was designed as a "mass termination" service. When you dial a 900 # by AT&T (such as the "hear space shuttle mission audio" number) you get routed to one of twelve "nodes" strewn throughout the country. These nodes are each capable of terminating 9,000 calls >PER SECOND options available, where the customer and/or the IP pay for all/part of the call. The big difference between 800 and AT&T 900 is >NOT "who pays for the call" (there are free 900 numbers) but "how many people can it handle at once". The IP is responsible for providing program audio. AT&T is prohibited from providing audio-program services (i.e. tape recorded messages) [As with any rule, there are exceptions to these as well] The last SAC we'll deal with is 700. I've seen ads on late-nite television for Group Access Bridging service (GAB) under 700 numbers, with a elephantine dialing sequence. The one that comes to mind is 10041-1-700-777-7777. [I make no guarantee about the quality or availability of this service. I don't even know if it still exists.] If you were to dial 1-700-555-4141 you will hear a recording announcing your Equal-Access carrier. (Some carriers ignore the last four digits, and any 700-555 number will give the announcement). This is signalled the same as 800 service, and may or may not be billed ENTIRELY at the discretion of the IEC. In New York, under PSC tariff you can order 900 and/or 700 blocking as well as 976, 970, 550, and 540 blocking in various (but not entirely orthogonal) combinations. What in ONE carrier might be a customer service hotline (Dial 1-700-I AM LOST) might for another be a revenue product. There is LITTLE standardization of 700 usage from IEC to IEC. The one last dialing pattern that is worth mentioning is what's called, "cut through dialing". Try dialing 10220#. If Western Union comes to your town, you'll get a FG-A style dial tone. Presumably if you had a Western Union "Calling Card" [I don't know their term for it] you could dial a call. (If someone DOES have WU service, could they please check this out for me?) Glossary: ANI - Automatic Number Identification. An MF sequence that identifies your line for toll billing information. Often confused with ANAC (Automatic Number Announcement Circuit) which reads your number back in a synthesised voice. BOC - Bell Operating Company. A often misused term (even in this very article :-) that in general usage means, "Your local exchange carrier." Since most of the telephones in the country are served by what used to be the Bell system, we tend to use the term. The proper term in this case, however IS "Exchange Carrier [EC]" They provide service within your LATA. FG-A - Feature Group A. Line Side termination for Long Distance carriers. The old 555-1234 for Widget Telephone Company then dial an access code and the number style dialing is called FG-A. FG-B - Feature Group B. Trunk Side termination for Long Distance carriers. (aka ENFIA B). 950 service. This is LATA wide service, and doesn't cost the customer message units. ANI is only provided when the trunks terminate in the End Office (as opposed to an access tandem). FG-D - Feature Group D. Trunk Side termination. Provides 10xxx dialing, 1+ pre-subscription dialing, and Equal Access 800/900 service. Only available in electronic offices and some 5XB offices (through a beastie called an Adjunct Frame.) GAB - Group Audio Bridging. Where several people call the same number, to talk to other people calling the same number. "Party" or "Chat" lines. IEC - Inter-Exchange Carrier. Someone who actually carries calls from place to place. AT&T, Sprint, MCI are all IECs. IP - Information Provider. Someone who sells a value-added service over the telephone. Where you pay for the INFORMATION you're receiving, as well as the cost of TRANSPORT of the call. NXX - Notation convention for what used to be called a "prefix". N represents the digits 2 through 9, and X represents the digits 0 through 9. There are 800 valid NXX combinations, but some are reserved for local use. (411 for Directory, 611 for Repair Bureau, 911 for emergency, etc.) ONI - Operator Number Identification. In areas with some styles of party-line service, the CO cannot tell who you are, and the operator will come on and say, "What number are you calling from?". You can lie, they have to trust you. They MAY know which PREFIX you're coming from, though. PTN - Plant Test Number. A regular 10 digit number assigned with your inward WATS line. This may NOT be a 'dialable' number from the local CO. (A friend has a WATS line in Amherst, MA [413-549, #5 ESS] and you cannot dial the PTN locally, but you can if you come in on a toll trunk.) SAC - Special Area Code. Bellcore speak for area codes that aren't really places, but classes of service. ============================================================================ Closing note: The information in this [Guide to North American Area Codes] first appeared in various parts in TELECOM Digest Volume 9, issues 2 and 15; January 3 and January 15, 1989.
