A customer has stated they keep dropping calls and has asked us to monitor their d channel traffic for any messaging that would help pinpoint the cause for the dropped calls. Is this a possibility on the adtran, or where would this need to be monitored at?
Have you tried "debug isdn l2-messages pri X" and "debug isdn l2-formatted pri X"? This should allow you to see the D channel signaling.
Hope this helps!
