[cisco-voip] h323 PRI two trunk groups

[Jason Shearer]

Yea....I have used NFAS to share signaling traffic between two separate physical trunks but can it be used between two trunk groups on the same T1?  If so, you might try a config like this:

controller T1 0/0/1
 cablelength long 0db
 pri-group timeslots 1-12 nfas_d primary nfas_int 0 nfas_group 1
 pri-group timeslots 13-24 nfas_d primary nfas_int 0 nfas_group 1

Once again....not sure if you can actually run NFAS on PRI channel groups on the same T1.  Not really sure why you would want to do this either.....what is the carrier saying about this?

Yes, this is call NFAS. After the controllers are configured, there is only 1 serial interface.

controller T1 0/0/1
 cablelength long 0db
 pri-group timeslots 1-24 nfas_d primary nfas_int 0 nfas_group 1
!
controller T1 0/1/0
 cablelength long 0db
 pri-group timeslots 1-24 nfas_d backup nfas_int 1 nfas_group 1
!

interface Serial0/0/1:23
 no ip address
 encapsulation hdlc
 isdn switch-type primary-ni
 isdn incoming-voice voice
 no cdp enable

I have a vendor who has requested I split up a single PRI into two separate trunk groups but with only one d channel.  I am not sure if this can be done or even how.  Anyone have insight on how to do this?
