The only time you will get a clocking source problem is if you have multiple T1s connecting to a router from different destination switches.<br><br>For example, you have a frame-relay T1 and a PRI... <br><br>You have to identify to the router which WIC is going to be the master clock. In which case you will see slips on the other T1.
<br><br>I do not believe there is any work-around. It is possible (though unlikely) that there are some Cisco routers that can have multiple clock sources...<br><br><br><br>Jonathan<br><br><div><span class="gmail_quote">On 12/1/06,

<div><br></div>What do you do if you have multiple potential clocking sources?
It is<br>likely at a site that you can have connections to Local and
Long<br>Distance service providers as well as to a PBX.

can only have one clocking<br><br>source. So if all 12 terminate to the
