We had problems with slips between a data T1 and our voice PRI, provided by different vendors, where they were connected to the same 2-port VWIC. We just installed another VWIC card, move the data circuit onto it and the slips went away.<BR>
<BR>
So I guess depending upon what kind of hardware you have available you can correct this issue different ways.<BR>
<BR>
Here's a nice link about clock slips.<BR>

<BR>
The impact of not creating two separate clocking domains is having<BR>
slips on one of your controllers. The impact of slips can vary - it<BR>
will kill nearly any fax or modem on it, and can cause mild amount of<BR>
clips, bits, and audio noise on your voice calls. Many people have it<BR>
on their network for extended periods of time since people have become<BR>
accustomed to "cell phone quality". Faxes and modems won't play on<BR>
it, however.<BR>
<BR>
To create two clocking domains you need two different groups of DSPs.<BR>
This is usually done with a card like the NM-HDV or NM-HDV2, where<BR>
there are DSPs on a NM you insert into the router.<BR>
