The T3's timing is logically independent of the subrate channels. The T3 is configured to take clock from the line. But the timing on the subrate DS1s should be identical, since they're all on the same DS3, right?

No, I was just wondering if there is generally one that carries the timing
on a T3.

No particular reason for choosing that one. Should I have chosen another?

Thanks for sharing.  Why did you choose that T1?

Someone e-mailed me privately off-list with a link to:



http://www.cisco.com/c/en/us/support/docs/routers/2600-series-multiservice-p
latforms/48567-clocking.html

Which clued me into the fact that I can take global TDM clocking off a
particular T1:

      tdm clock priority 1 6/0:1

So far, that seems to have fixed the slips!  I'll see if it holds.
Thanks a lot for the pointer!
