NM-HDV-2T1-48 design help

We are currently using a NM-HDV-1T1-24 in a 2621 to act as a gateway between our CCM and our Definity PBX. We would like to upgrade the HDV module to a NM-HDV-2T1-48 and use the 2nd T1 to tie this Definity PBX to another Definity PBX at a remote site via a 10meg IP over Sonet link.

We are looking for documentation on connecting a Definity PBX and a CCM system into another Definity PBX via a 2621 (or similar device) w/ a NM-HDV-2T1-48.

Any information would be greatly appreciated.

Just connect the other Definity PBX to the 2621 just like the first one.

You can either route the calls from one PRI to the other using POTS dial-peers on the 2621, or you can have the CallManager do this with route patterns. There is nothing particularly challenging about this configuration compared to what you have already done.

Dave, could you give some syntax or configuration examples to do this?
