Preparing to order a T1 (not PRI) for our asterisk box. The telco has
offered me several options that I am not sure of. Which would be best
for use with asterisk? The box has the Digium card in it, BTW.
1. Dial Tone - No, Yes - Precise, Yes - SCC
2. Framing - SF, ESF
3. Line Coding - AMI, B8ZS
Go T1 with PRI signaling. Farming and line coding is for all T1's. We
use ESF (extended super frame) B8ZS ( I forget B8ZS stands for but it's
a newer line coding) . If you have it avaible to you, Signaling type
should be PRI. The rest of your numbers 4-7 are in the PRI signaling.
No sound dif
So the only difference with PRI is caller ID? What I am trying to
determine is if the PRI has enough advantages to give up the voice
channel used by the D channel. For what I am doing, caller ID is not
necessarily that important for my application.
Is a non-PRI T1 significantly harder to confi
Is a non-PRI T1 significantly harder to configure with Asterisk?
I don't think so. I moved to SS7 signaling and convert down to other
formats. I've used CAS signaling for years and it has worked just fine.
But not with Asterisk. Remember That CAS signaling is an inband format
and requires mo

The PRI signalling is more robust than any of the alternatives (except
SS7). Call setup is faster, you can get DID, caller id and much better
error reporting from the pstn.
You will also have far fewer instances of 'glare' using CCS instead of CAS.

Thanks for the replys. I'm
convinced. PRI it is.

This is not a direct answer to your question since I am mostly familiar
with EuroISDN. Most PSTN providers in America seem to charge extra for
every single feature on a
Ben, That is the correct choice for an Asterisk box. good luck.
