An AT&T engineer gave me these acronyms regarding fire alarm circuits at one of our new locations. He will not give me any explanation about what they are; except that CSNC will only work on copper, while PMNC will work on copper or fiber. Does anyone have any idea what these are? Our AT&T sales rep had no idea how to order these, and as usual the job site needs a couple installed yesterday.
Regards,
Bucky

Hey Bucky…. The engineer was giving you circuit ID’s with the “CSNC” & “PMNC.” I’d be betting you were speaking with an Outside Plant Engineer (whom rarely know circuits) and the feller was working off a “cheat sheet” of some kind. The 1st two alpha characters you were given of “CS” and “PM” are the service codes and really would be the only thing that would matter….

Here’s the Telcorda description of service code “CS”
Service Code CS - CHANNEL SERVICE
Definition: Provides a channel which has the capacity of transmitting up to 30 baud.
The channel does not have access to the switched message network.

FYI… I THINK service code “PM” was retired. (Doesn’t mean it’s not still being used by that company.

If you tell your AT&T sales rep those are “service codes” or circuit id’s… That should get ‘em going in the right direction.

Bryan,
Thank you much! You are correct in that the engineer did not seem to know what he was talking about. I will pass this on to our sales rep.
