Hello all, I'm provisioning a T1-PRI for a Digium T410P with my local TELCO. The TELCO has asked me to pick a line protocol and has the option of several RBS protocols, like 5ESS (Lucent), IN2 and others. The switch is a 5ESS, but the "normal" (according to the sales rep) protocol is IN2. I see from the doc on zaptel, that many protocols are supported. As I have a choice, is one of the PRI protocols "better" that an another? I suspect that some protocols support features over another but can't find much on the specifics. Recommendations and reasons please. Jon -------------- next part -------------- An HTML attachment was scrubbed...

A T1 PRI should be B8ZS, ESF. The protocol can be either 5ESS or NI2(not IN2).
Either will work, primarily both ends need to be setup for the same protocol,
but I would go with NI2 as that is a more 'universal' procotol(not
switch specific like 5ESS).

Hello all,
I'm provisioning a T1-PRI for a Digium T410P with my local TELCO. The
TELCO has asked me to pick a line protocol and has the option of several RBS
protocols, like 5ESS (Lucent), IN2 and others. The switch is a 5ESS, but the
"normal" (according to the sales rep) protocol is IN2. I see from the
doc on zaptel, that many protocols are supported. As I have a choice, is one of
the PRI protocols "better" that an another? I suspect that some
protocols support features over another but can't find much on the
specifics. Recommendations and reasons please.

We use NI2, it's the "standard" for north american telco. We tried another I can't remember for the life of me which it was, but we had the least problems with NI2. -----Original Message----- From: Jon Bebeau [mailto:jbebeau@1nettw.net] Sent: Friday, November 19, 2004 8:22 AM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] "Best" line protocol for T1 Hello all, I'm provisioning a T1-PRI for a Digium T410P with my local TELCO.
