"Last input 5d05h, output 5d05h, output hang never"
anything in the log? can you swap the t1 ports? i've never seen a
situation like this that was fixed with removing/adding interface
configs - you may want to try doing a 'default interface serial x/x'
and readding, but I think there's a L1 issue here.
