Hi,

This is s general denial event. There could be many reason you may experience such denial event. I want you to check following:

1. Any slip errors on DS1 board & also check if sync is configured for system
2. If it is non-ISDN trunk ( CAS trunk), I want to check country protocol( ABCD CAS bits) & match it with far-end switch. Place a E-1 / T1 analyzer on line to undersatnd who is droping
3. If it is a ISDN trunk, I will encourge you to raise Service request to Avaya Product support team. Q.931 message are required to be analysed to understand the actual cause of this drop.

Thanks for posting your query on Avaya Support forum.
