Kaiser,
It could be caused by your own cabling between the router to csu/dsu or
between the smartjack to csu/dsu. You might want to replace those. If you
still have a prob, use any other router you have available for a testing
purpose to ensure that the serial interface is clear.
I hope this helps.
Yuki
