asterisk users - Apr 2006 - Telephony newbie need advice for integration Nortel MICS 4.1 with Asterisk via T1/E1 interface

I have gone through some archive about Nortel MICS (Meridian ?)+ Asterisk
Integration but I'm not sure whether same as my case .



70 telephone sets
       |
       |
Nortel MICS 4.1  --------- Asterisk
       |
   PSTN



I have read the David Gomillion's Guide and got the idea . However, my plan
is slightly different from what he did , I need to use Nortel MICS to
connect to PSTN (I have the 2 Vonage lines which I think not allowed to be
connected from Asterisk unless getting a FXO/FXS card )

However, the Nortel reseller told that I need E1 card instead of T1 card to
connect between Asterisk and Nortel MICS because Mexico is using E1.


Anyway advice and information is welcomed , thanks.

Well, you control both ends, so I can't see how it would matter much.
So long as the Nortel card matches the Asterisk card, you should be good
to go.  Asterisk doesn't have artificial limits like Nortel does, so
check what will work in your Nortel first.  For example, my Norstar
system won't allow me to switch from E&M Wink to PRI without forking
over some cash.  Your E1/T1 issue could be in the same boat.
 
There was an Asterisk+Vonage discussion on this list a week or so ago...
