[cisco-voip] NFAS with D Channel Back Up

[Michael Thompson]

Yes, NFAS is supported in H.323 gateways.

 

When you create the PRI group under the controller T1 X/X/X, you'll use the
command pri-group 0 timeslots 1-24 blah blah blah, well one of those blah's
is the key word NFAS.  There's a little more to it than that in order to
create the NFAS bundle, but it's RELATIVELY straight forward.

If you can't find the documentation on it (or don't have access to CCO) one
of us should be able to point in the right direction.

Subject: [cisco-voip] NFAS with D Channel Back Up

 

 Getting ready to finally convert PSTN trunking from some larger Nortel PBX
systems to Cisco gateways. Up to this point we have been using PRI tie lines
between the PBXs and Cisco gateways and routing PSTN calls via the PBX.  On
the PBXs we are using various PSTN PRIs using primary and backup D channels
and in some cases NFAS. Can these connectivity options be recreated in a
Call Manager 6.1 environment or will I need to order new PRIs with
individual D-Channels? Can not seem to find any info on this

 

We use a combination or 28xx and 38xx gateways

 

Thanks!

Steve
