It seems a lot of newbies post here without knowledge of telecom acronyms . Such as POTS ,BTN , SISO . If you could compile a glossary it maybe very helpfull to the posters . Installer rated members and up should be able to manage this forum without spending to much time . It would be tragedy for all this knowledge to be lost .

That would be nice but without breaking copyright laws that would be a lot of time/work. My suggestion would be for anyone wanting to learn telecom terms pick up a copy of Newtons Telecom Dictionary

I forgot about copyright laws . Thanks Metelcom

However, there are good sites that could have a link to,

Example of one that isn't helpful for a non-industry user: TIA Glossary of Telecom Terms ( search "Registered Jacks")

Search results: telecommunication terms on PDF format

No Drinking on the Job-Site, Mr. Bloom.

You clever lad, you.

NTF = no trouble found UE = user error PRI = prime rate interface BRI = basic rate interface COT = central office trunk CO = central office . UE was the most common trouble found ,women were the worst offenders for reasons unknown . Then the ole office jerk that proclaims " I will have your job for that " my response was " you could not live on the pay " .

You missed the most important acronym:
CCWT - Came Clear While Testing

Fairpoint (now Consolidated Communications) favorite trouble ticket closing note, NTF a close second.

Hi-Ro: high resistance open. These can be buggers to track down and/or prove to the LEC that's the issue.

Lets not forget COD , customer on drugs .

POS [in regards to equipment]

The industry sure has a lot of TLA's don't they...
