[Asterisk-Users] E1 + T1 timing in one box

Thanks! I'll set the dipswitch on the CAC to provide sync, currently the T1
is free running, but its only been up for an hour or 3 so no slips yet.

Will excessive slips generate a yellow alarm? Then I'll know what to
watch...

Sure, the Digium T1 can be left in free-run. The place to set up loop 
(or line) timing is in the CAC channel bank. That way there wouldn't be 
slips.
