<DIV><BR></DIV>The 5400 has only one clocking domain. So, if you are
getting clock from slot 6 port 0, then this is the time source for the whole
TDM bus. So, all other T1s on the 5400 will be synchronized to that
source, and anything that takes clock from those T1s should be
synchronized.<BR><BR><A class=moz-txt-link-freetext

taking clock from the line. Maybe it's free running or maybe it's taking

I rewired the pinouts from telco in order to connect them directly to a t1

mux and coming across a channel on the t3. It works, but the slips are
exactly the same.</FONT></DIV>

Joe,<BR>> <BR>> Sounds like, conceptually, you've set things up
right. I would <BR>> doublecheck on the customer routers to make

line.<BR>> <BR>> On the 5400, you should be using "tdm clock
