<DIV><FONT size=2 face=Arial>Yeah. The DACS is not the problem though, because
we have two circuits going through the DACS, in fact they are two circuits that
are exactly the same, following the same path from our AS5400 through the telco
to the same router (an IAD2400) at the same customer, one is getting slips
one is not. Both go through the DACS. The only difference between them is that
one has just a channel group for T1 service and the other has both a channel
group and a PRI group. The one with just the channel group is plugged into
the native T1 port on the IAD2400. The one with both is plugged into a card that
will support multilple tdm groups on a card.</FONT></DIV>

<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

Joe,<BR>> <BR>> Sounds like, conceptually, you've set things up
