I upgraded the IOS of a router for a remote cusotmer site this morning. We are using encapsulation frame-relay IETF between the telco and my router. There is a T1 between teh telco and my router. After the upgrade was complete, I issued the reload command. I then lost connection, since I was telneted into the router, but then the interface never came back up. I had to have some one power cycle the router to get the interface back up. I have done this with other remote routers using the same encapsulation but with "service-module t1 timeslots 1-24" command and they came back up just fine. Is "service-module t1 timeslots 1-24" command required for IOS version 12.2(34)? Anyone have any insight into this situation?
I have this problem too.
