Help with config for 2620 routers with VWIC-2MFT-G703 for E1

Unanswered Question

Currently have 3 x 2620 routers each fitted with 1x VWIC-2MFT-G703 interface cards. E1 G.703 channels are 75ohm unbalanced, unframed, linecode is HDB3, clocksource is line. The E1 controller shows no alarms and CD is lighting up OK. However cannot ping between routers or communicate between routers either back-to-back or over E1 channel. Should the E1 controllers be 'mapped' to an interface, given an IP address or similar?

Any suggestions or samples of working IOS coding for similar E1 connections would be greatly appreciated.
