Note: You must consult local records for the location and designation of the
equipment rack where the G250/G350 is mounted.
A MAJOR alarm on a trunk indicates that alarms on these trunks are not
**
downgraded by the set options command 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 form. Settings must be compatible with the local environment and with parameter
settings on the far-end. Refer to Administrator's Guide for Avaya Communication Manager,
555-233-506, for information on how to administer trunks. For the correct settings for
administrable timers and other parameters on a country-by-country basis, see your local Avaya
representative.
Direct Inward Dial trunks connect the switch to the CO, and allow outside parties to call directly
to an extension in the system. MM711 supports eight incoming-only ports.

DID Trunk Operation

The DID port receives three to five 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.
