whenever i get a hick up on my T1 to the internet my router interface goes to a "serial 0/0 is down, line protocol is down". Once this happens I'm forced to reboot the router to get the interface back up. I do a 'no shut' but that doesn't work - I have to reboot.
That seems quite strange to me. Usually when a serial interface says the state is down it is an indication that it is not seeing any electrical signals (no DTR, DSR, or anything similar). In my experience it has usually been a hardware issue or a physical connection issue. I am surprised that a reboot of the router brings it back into service. I would wonder about whatever the 2600 is physically connected to. Is it possible that whatever you are connected to gets into a wierd state and gets straightened out when the router reboots?
