Well, I have hit a snag in studies. All was going well until I got to Chapt 6 CVOICE and was trying to confirm ops based on example config in the book.
I have a 2811 and 1760V connected back to back with VWIC-1MFT-T1s configs as follows:
2811

The layer 2 status will flip flop back and forth between awaiting_estab and TEI assigned.
If I plug either device into the NxT1 port on my adtran 550 i get the following:
Global ISDN Switchtype = primary-ni
ISDN Serial0/3/0:23 interface
dsl 3, interface ISDN Switchtype = primary-ni
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = [COLOR=red]MULTIPLE_FRAME_ESTABLISHED[/COLOR]
What am I missing?
What is the Adtran providing that the 2911's VWIC-1MFT-T1 is not? or what is the issue with the 1760's config? Must be something simple I am missing!
As a note: My Comptroller (WIFE) gave me permission to order up some additional equipment as a reward for passing CCNA and my Adtran Atlas 550 is going away. one of the new routers is a 3745 with a pair of VWIC-2MFT-T1s that I plan to use to replace the Adtran (Quad-T1 module was way out of my budget range) so I am trying to get things set up before everything arrives.
