ISDN Bridging

Hi all,

I have a problem with this. I need to bridge some PCs over ISDN. in total there will be 7 remote sites, 6 over ISDN and 1 over a serial link. The serial link is working but I'm having trouble with the ISDN. I had a trial set up, using a 801 for the spoke on ISDN and a 2522 for the hub. The serial link has a 2501 at the remote end. The ISDN link came up and passed traffic. The 2522 was then swapped for a 3620 with 8 port bri, and NM2FE2W loaded with WIC2Ts. The config from the 2522 was mirrored across to the 3620 with modifications for the change of hardware.

The link now comes up but does not pass traffic.

Suggestions please.

Edited sho ver and sho run of the 2522 and 3620 are below. IP addresses have also been edited.
