Today we finally set up our testbox, an digium E1 connected to the outside world and a digium T1 connected to a CAC-accesbank-1. After some fiddling and finding out the T1 cable was faulty we got everything working. Great when the analog phone starts ringing!! Question is how I should set the sync timing in zaptel.conf though, The E1 gets sync from the network, but can an E1 slave to that? (E1 -T1 timing is quite different) or should I let the T1 sync to the CAC? -------------- next part -------------- An HTML attachment was scrubbed...

You will definitely have slip in the arrangement but it shouldn't affect you unless you try to run data or are listening to a very smooth tone. Mark
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.
