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).

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.
