Note: For Avaya G350 systems you must consult local records for the location and designation of
the equipment rack where the 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.
The MM710 supports T1/E1, and delivers the same functionality as the DEFINITY TN464 circuit pack.
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 "Chapter 12, Managing Trunks" in the Administrator's Guide for Avaya Communication
Manager, 555-233-506 for information on 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.
A DS1 CO (central office) trunk provides a link for digitized voice or data communications between the
system and a central office switch. There are two types of DS1 interfaces:
•
24 DS0 channels on a 1.544 Mbps link
•
31 DS0 channels + 1 framing channel on a 2.048 Mbps link
32-channel mode is supported on TN464 Media Modules and on MM710 Media Modules.
The CO-DS1 maintenance object monitors and maintains a CO trunk port on a MM710 Interface Media
Module. See MG-DS1 in this chapter for more information about this Media Module. The DS1 Media
Module supports low level CO trunk signaling interfaces for both ground-start and loop-start trunks. This
maintenance strategy covers the in-line errors log, initialization tests, periodic tests, scheduled tests,
demand tests, and alarm resolution.
Three trunk service states are specified by DS1 CO trunk maintenance:
