Avaya 03-300430 User Manual

For systems supporting circuit packs:
If ATMS testing is enabled, check the error log for ATMS errors 3840 and 3841.  If the error log 
indicates that measurements exceeded acceptable thresholds, and no other trouble is found 
with test trunk, run the ATMS test call with test analog-testcall port location 
full.

Note:

Many trunk problems are caused by incorrect settings of parameters on the trunk 
group administration screen.  Settings must be compatible with the local 
environment and with parameter settings on the far end.

Analog CO trunks are 2-wire analog lines to the CO that support both incoming and outgoing 
calls.  CO trunk circuit packs have eight ports, each of which provides an interface between the 
2-wire CO line and the 4-wire TDM bus.  The system supports the following CO trunk circuit 
packs:

CO-TRK

MAJ

1

1. A MAJOR alarm on a trunk indicates that alarms on these trunks are not downgraded by set 

options and that at least 75% of the trunks in this trunk group are alarmed.
