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?
From my understanding, not necessarily. I remember years ago having a DS3 with the individual DS1s connected to three or four different telcos (we were shopping around at the time). The DS1s from one upstream telco had slightly different timing than a DS1 from another telco.
Oh, yeah--well, that makes sense. I meant if all the channels on the DS3, and the DS3 itself, is coming from the same network element on the carrier side. Presumably that box has a global timing signature for everything it puts out. -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/
