1. A MAJOR alarm on a trunk indicates that alarms on these trunks are not downgraded by set options
and that at least 75 percent of the trunks in this trunk group are alarmed.
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 the Administrator Guide for Avaya Communication
Manager, 03-300509, for information about how to administer trunks. Refer to your Avaya
representative for the correct settings for administrable timers and other parameters on a
country-by-country basis.
Direct Inward Dial (DID) trunks coming from the Central Office (CO) allow outside parties to call
directly to an extension in the system. DID Trunk circuit packs include:
DID trunk circuit packs and the MM711 Media Module support eight incoming-only ports. Each
port provides an interface between the 2-wire analog CO line and the 4-wire TDM bus on the
switch.
Not all tests that run on circuit packs are applicable to media modules. These tests will abort
with error code 1412. This error can be ignored.

The DID port receives three to seven digits from the CO that are used to directly connect an
outside caller to the called station without assistance from an attendant. For each call, the CO
switch signals the system by opening and closing individual DID loops (one of the eight ports),
causing the starting or stopping of loop current.
