Avaya 03-300430 User Manual

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. Refer to Administrator 
Guide for Avaya Communication Manager, 03-300509. The Application Notes 
section of that book shows the correct settings for administrable timers and other 
parameters on a country-by-country basis.

The following circuit packs, including every suffix such as TN760D, support analog tie trunks:

Each tie trunk circuit pack occupies a port circuit pack slot and contains 4 port circuits. Each port 
circuit supports 1 analog tie trunk used to connect the switch to another PBX across 1- or 2-way 
dedicated circuits (see preceding list).

1. 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.
