You might want to put a t1 test set on the line and check and see if the
clock frequency is moving.

Are these T1 frame errors, or a higher level? If you believe this to
be a T1 concern, you should be checking at the T1 level - "show
controller T1 1/0:24" for the AS5400 and "show service-module serial
x/y performance-statistics" for the WIC on the 2600. Both of these
commands will display the T1 statistics in 15min intervals.
If you see errors there, most HDSL4 smart-jacks have a serial port for
pulling stats and levels, if they are your smart-jacks to be checking.
HTH,
Andy
