</div>My guess is you have a cabling problem and that span TE2/0/1 is<br>
going into and out of alarm.<br>
<br>
Each time it goes into alarm the core of DAHDI will look for a new<br>
span to use as a timing source for asterisk. If TE2/0/1 is the<br>
"preferred" timing source, when it comes out of alarm, DAHDI will<br>
switch the timing back to it.<br>
