Greetings...

I have a TE410P with four T1's going into it. Things look roughly like this:

#1      Goes to PBX -- we're responsible for timing
#2      E&M span to telco 1
#3      PRI span to telco 1
#4      PRI span to telco 2

If I set primary sync source to span 2, users report strange echo, distortion, and crosstalk problems, which sound remarkably like frame slippage on spans 3 and 4. If I set it to use #3 as primary, the other spans report problems, etc. Generally, it seems like the clocks just aren't quite close enough to make things work right all of the time. I don't forsee either involved telco doing anything at all about this.

Is there any way to see if there is some sort of weird timing problem? Even better, is there a way to get things to work right on the TE410P?

Thanks :-) -rt
