[Asterisk-Users] "Best" line protocol for T1

[Matt Schulte]

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.

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
