I am trying to setup the very first PRI ever on my switch so I really have nothing to go by.

The CP is a TN767E and the PRI I have ordered is full 23 channels with 1 signaling channel using b8zs and esf.

The first bump I discovered was that I had to do a 'add ds1 01B16'

Now I am trying to add the trunk and I am building all the ports in and now I get a "Must add this trunk board to a Sig Grp before assigning this ISDN-PRI port" and I am not 100% sure what to put. I am assuming the number "24" since the 24th channel is used for signaling.

Is this a correct assumption?

A TN767 will provide D-channel signalling in a FAS environmnet. What a TN767 will NOT do is provide primary or secondary D-channel signalling in a NFAS environment.

Assuming an R7 or better. Earlier versions require data mods, processor channel assignments, or ISDN-PRI via PACCON RTUs and the PACCON circuit pack.

1) add ds1 ppccss (port network, carrier, slot)
b8zs, esf, isdn-pri . The rest gets tricky. I have attached a document to assist.

2) add sig xx or add sig next
With a TN767 it must be FAS (Facility Associated Signalling). The channel will be 24, so enter ppccss24. Don't worry about the trunk group assignment.

3) add trunk xx or next
type is isdn. the service type is most likely "public-network" but that's going to depend on your carrier. most of the other defaults will work.

These are guidelines, not absolutes. Setting up an ISDN-PRI trunk group is not a simple task. There are lots of variables that you simply learn with experience. The entire setup can be activated in less than 15 minutes by an experienced tech working in conjunction with a competent service provider technician ... but that comes from many late nights of beating your head against the wall and dealing with Telcopleagics at the LEC end who end up wasting your time.

Good Luck!
