NFAS across two routers

I have configured NFAS a couple of times on a single router, but I now have a customer asking if NFAS is supported across two seperate routers. Can I have two PRIs with a single D channel across two seperate routers. The only document I found stated that NFAS is not supported across two seperate MRPs on an ICS7750. I am using a pair of 2811 routers.


Re: NFAS across two routers

Well, I can't find anything specifically addressing this, but I would be pretty certain it is not supported. Part of the NFAS config is defining a primary, and there is no way to tell it that that primary is in another box, it will want to see a controller defined as primary somewhere in his own config.

Re: NFAS across two routers

I just ran across this in the feature matrix in the 3600 product brochure:

ISDN Non-Facility Associated Signaling (NFAS)

Allows single D channel to control multiple PRI interfaces in the same access server; allows configuration of backup D channel
