This to add that it is analog XCOT ckt.All other ckts of that card are working fine.

The only way I know to resolve this bug is to use a PLDN with MQUE=ALL as ATDN (instead of a real DN).

are all the other ckts analog loop start? might need to meter that for loop current, could just be a marginal trunk. i never use loop on analog trunks, glare can still be a problem

Yes, all other ckts are analog loop start and are working fine .Could it be a hardware fault.I hav plan to replace the hardware 2moro.

This is not a bad trunk issue. Lockout happens if a destination DN (ATDN) is busy then a call comes in from CO.
This is known bug in Rls.3 & Rsl.4 using analog XCOT trunk with enabled Busy Tone Supervision.

Don't use FBA, that sends call to ATTN (forward busy Attn.)
