Bridging with 1720 over T1 does not work

[service]

I have two 1720 both with WIC-1T configured for bridging only. I think the configuration is okay and even the interfaces (e0 and s0) are up no traffic is running. The sh int s0 output shows no received packets. Because other bridges were installed and working before I assume the link is well. What can I do solve the task?

Did you check if the interfaces were in forwarding mode? or are they blocking? you need to check in which mode are the interfaces.. (i.e. spanning-tree)
