try 'network-clock-select 1 T1 0/0/0'
if you run a sh network-clocks, your output should be similar to this:
#sh network-clocks

I am getting timing slips on a ATM T-1 when the clocking is set to line.
Setting it to internal is of course no better.
I am using a VWIC2-1MFT-T1/E1 on IOS c2800nm-spservicesk9-mz.124-21a.bin.
Links to troubleshooting docs
about slips or suggestions on what is wrong with the config will be
appreciated.
