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, for information about how 
to administer trunks. The Application Notes section of that book shows 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

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.

 Although the DID-TRK MO is provided for a G700/G350 Media Gateway, this MO 

only partially supports the MM711 Analog Media Module.
