PRI config on 2811

[kunz12]

Hello folks -

I am going to be configuring a 2811 router which will have 2 PRI's on it. Both those PRI's will be used for dial-up access from remote sites. We will have one 800 number for dial up purposes. May have a second 866 number, but not sure at the moment.

We are getting the PRI lines from Verizon. Verizon sent me an email today asking the following:

"Do you want a Primary D on each ds1, which will be 2 separate trunk groups that over flow or one trunk group of 46 B channels, 1 Primary D channel, and 1 back up D channel?"

My answer was the latter, one trunk group with 46 channels.

Do you guys see an issue with this? This is very critical for our business, so I just want to be sure...

Thanks for your help!

NFAS is a tricky thing to get working on CISCO. You better know very well what you are doing and how to configure it and troubleshoot it on the router.
If I were you I would do two separate PRI's, each with a primary D channel.
NFAS does not buy you anything with two PRI's.
My two cents.

I like to have two D ch, this way if the main PRI is down you still have a connection. Besides it's just one channel your giving up.

You can have Verizon group the Pri's and make sure who is
ascending and descending.
