[Asterisk-Users] Telephony newbie need advice for integration Nortel MICS 4.1 with Asterisk via T1/E1 interface

[CG]

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

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.
