<DIV><FONT size=2 face=Arial>We had considered the possibility that the
problem might be coming from the mux that everything was passing through. I
rewired the pinouts from telco in order to connect them directly to a t1 port
on the AS5400 (Controller 6/1), rather than passing them through the mux and
coming across a channel on the t3. It works, but the slips are exactly the
same.</FONT></DIV>

<DIV><FONT size=2 face=Arial>Right next to it is the trunking circut plugged
into 6/0, it runs fine, no slips. I would like to change 6/1 to internal
clocking, btw, so that it should be following the clock that is being derived
on 6/0, but can't find anyway to change that on the t1 ports. So as it stands
right now, both 6/1 and the customer router on the other end of that t1 are
set to clock-source line, with no mux between them. And getting
slips.</FONT><FONT size=2 face=Arial></DIV></FONT>
