CRPF Proprietary Acronym List
« on: February 28, 2014, 08:06:18 PM »
If you are new to the forum, your telephone knowledge may be somewhat limited to acronyms used by members in forum posts. Some are common sense but others are obscure. As such, this reference list was created and is being maintained to help those who would like to find out what an acronym means.

This is the most complete list to date for forum acronyms. A Generic Acronym List is available in another topic and it contains over 1,000 modern, common acronyms. Also, a list of acronyms used by repairmen or given to repairmen on trouble work orders are listed at the end of this post (scroll to the bottom).

Feel free to make any suggestions (strongly encouraged) to add to this list by posting a new reply to this topic with one or more acronyms and their meanings and/or unknown to you acronyms followed by a few question marks. All contributions are greatly welcome.

New additions will be copied into the alphabetical list below. Unknown acronyms submitted will be added to the list when their definitions become known.

Thanks for everyone's help in building this list.

Saw the acronym/abbreviation list thread, and wanted to post some to it. Thought I'd add these to the list, since I had no idea what these meant when I was a newbie a few short months ago.  Even though they're now second nature to us, they might not be to a "n00b":

Telco:  Telephone company
CO:  Central office (the telephone exchange office where the switching equipment and power source for the phone system covering a certain area is located)
REN:  Ringer equivalence number  (represents drain on ringing voltage a single phone will have; Western Electric 500 = 1)
DTMF:  Dual-Tone Multi-Frequency; a.k.a. "touch-tone"
PBX/PABX/PMBX:  Private branch exchange/private automatic branch exchange/private manual branch exchange
KTS:  Key telephone system (similar to a PABX but can be manually programmed by the user, such as a Panasonic 616)
POTS:  Plain-old telephone service
PSTN:  Public switched telephone network  [Depending on which Wikipedia entry you look up, POTS is either one of the elements which make up the PSTN, or is synonymous with the PSTN itself...  demonstrating one of the many reasons Wikipedia should be taken with a grain of salt...  :P ]
SxS:  Step-by-step (electro-mechanical automatic stepping switch; now obsolete in most PSTN systems)
NPA-NXX:  Numbering Plan Area (area code); central office exchange code (see NANP)
NANP:  North American Numbering Plan
ATA:  Analog telephone adapter
VoIP:  Voice over Internet Protocol
CLLI code:  Common Language Location Identifier code
GTD-5 EAX:  General Telephone Digital Number 5 Electronic Automatic Exchange; a Class 5 digital telephone switch developed by GTE Automatic Electric Laboratories
CB:  Common battery; power source for the telephone is at the telco CO
LB:  Local battery; power source for the telephone is on-site, where it is being used (now rarely implemented)

I pulled this topic for about a day to update it, sort it out. It is now back and open to both use and suggestions of new acronyms, unlisted acronyms.

Please suggest them by posting a reply to this topic. All suggestions will be copied to the alphabetical list in the first topic.

The topic is now Unlocked.

If you know the meaning, please provide it.

If you don't know the meaning of an acronym not of the list, submit it with a few question marks following it ( ? ? ? ) and it will be added to the list once the meaning is known.

Thanks.

  PAP2T -- ?? (panasonic analog pulse to tone?)

As far as I know a PAP2T is a type of Linksys ATA.

Additions, though they may be only used in Britain:

ASTIC -- Anti-Sidetone Induction Coil
ELR -- Earth Loop Recall
LD -- Loop Disconnect, ie Pulse Dialling
pps -- Pulses per Second
PST -- Plug and Socket Telephone
STD -- Subscriber Trunk Dialling
TAM -- Telephone Answering Machine
TBR -- Time Break Recall

Right, some are not used in the US or are used differently.  For example in North America "STD" is usually used by the medical profession and public health agencies to refer to "social" ("sexually transmitted") diseases. 

DDD or Direct Distance Dialing refers to subscriber nation-wide dialing of toll calls.  More limited direct dialing of toll calls existed decades earlier but had no special name.

AST (antisidetone) and ST (sidetone AKA "booster circuit") were used but not concatenated with "IC" for induction coil.

DP rather than LD for pulse dialing.

"Ground" rather than "earth" in any reference to such a connection but "ground" or "earth loop recall" is almost never used here.  "Flashing" (momentary on-hook supervision) was the generally used method but there is no equivalent to TBR.

As far as I know a PAP2T is a type of Linksys ATA.

Additions, though they may be only used in Britain:

ASTIC -- Anti-Sidetone Induction Coil
ELR -- Earth Loop Recall
LD -- Loop Disconnect, ie Pulse Dialling
pps -- Pulses per Second
PST -- Plug and Socket Telephone
STD -- Subscriber Trunk Dialling
TAM -- Telephone Answering Machine
TBR -- Time Break Recall
