==Phrack Magazine== Volume Four, Issue Forty-Three, File 21 of 27 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + + + + + The Telephony Acronyms and Abbreviations List from Hell + + + + + + by + + Crisp GRASP + + + +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Well, here it is, the list from hell. Sure beats the old lists of 100 or so three letter acronyms. The whole reason for this list is so that you can crack almost ANY bell document. This list came from a few lists (one in Phrack a while back) and a few other Telephony lists here and there. Though it must be noted (and i want to take credit for it) that well over half of the acronyms and abbreviations were typed in by me, inputed into my database (of course I am not about to give out my database). It is always a good idea to start a database, one will learn a lot faster. It is doing things scientific like, and for someone as compulsive as I, solving the puzzle of the telephone company was easy as pie. I must say that all the hackers I have meet, and talked to are all compulsive as hell <G>. I think it is just what it comes down to, who is willing to learn. Any ways here is two fields in my database, one small part, but worth it. Though i do not think it will be able to help most of you out, just gets into too much, and understanding which acronym goes where, and understanding what goes where is hard. Well good luck! Greets to Bell Northern Labs, never see too much from you press wise! and to SRI, should have come to Cal. hah (Don knows what I am talking about, his funding is short) -------------------------------------------------------------------------- 15M Fifteen minutes 15S Fifteen seconds 1CF Singal party coing first pay phone 1FAC Interface packs 1FB One party flat business rate 1OF One party official (telco) business line 2SPDT Partial dial timeout in the second stage of a traditional 2-stage international 2SPST Permanent signal timeout in the second stage of a traditional 2-stage international 2SVCA Vacant code in the second stage of a traditional 2-stage international outbound 2W Two wire (pair) (circuit) 2WAY Two-way trunk groups 300 Log command menu (SARTS command) 376 Log clear (SARTS command) 384 Write log (SARTS command) 385 Read log (SARTS command) 399 Log print (SARTS command) 3KHZ Three kilohertz 3RNGR Three ringer 3WO Third wire open 4W Four wire (pair) (circuit) 600 Test menu (SARTS command) 600B 600-ohm briged connection 611 Detail tests (SARTS command) 621 Macro command menu (SARTS command) 631 Automatic test command (SARTS command) 735T 735-ohm compromise termination ?A Action field contains an error ?D Data field contains an error ?E Error exist in the message but can ot be resolved to the proper field ?I Identification field contains an error ?T Time-out has occured on channel ?W Warning message A A side (lead) (pair) A Area A Telephone number or trunk group and member number from trouble A/B Two wire phone connection (T&R) AA Automatic answer AA Packet analog access line INTER/TRA blocal 1-26 AABS Automatic alternate billing service AAE Auxiliary access equipment AAR Automatic alternate routing AAX Automated attendant exchange AB Packet switch trunk INTER/TRA blocal 1-26 ABATS Automatic bit access test system ABATS Automatic bit access test system (DDS service) ABC Automatic bill calling (TSPS) ABF Abandon failure ABF Abandon failure (MDII) ABHC Average busy hour calls ABL Auxiliary Buffer oder word Left half ABM Asynchronous balanced mode ( -> SABME) ABME ABM extended ABR Auxiliary Buffer order word Right half ABS Alternate billing service ABS Alternative billing service ABSBH Average busy season busy hour ABT Abort ABV Above AC Administrative computer AC Alternating current AC Assembly code ACA Asynchronous communication adapter ACB Annoyance call bureau ACB Automatic call-back ACC Audio communications controller ACCS Automated calling card service ACD Automatic call distribution ACD Automatic call distributor ACDA Automatic call disposition analyzer ACDN Access Directory Number ACDN Access directory number ACE Assignment change establish ACE Automatic calling equipment ACES Aris cabs entry system ACF Advanced communications functions ACFA Advanced CMOS frame aligner peb2030 ACG Automatic call gap ACH Attempt per circuit per hour ACI Answer controller interface (IOM2 monitor command) ACIA Asynchronous communications interface adapter ACK Acknowledge ACK No acknowledgement wink ACK No acknowledgement wink (MDII) ACKDB Acknowledgement database ACM Address complete msg.
