<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
