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 Administering Avaya Aura Communication
Manager (03-300509) for information on 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.
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 chels on a 1.544-Mbps link
● 31 DS0 chels + 1 framing chel on a 2.048-Mbps link

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. For more information about set
options, see Maintenance Commands for Avaya Aura Communication Manager, Media Gateways
and Servers (03-300431).
Note:
media gateways, consult local records for the location and designation of
the equipment rack where the media gateway is mounted.
32-chel mode is supported on the TN464C or higher suffix, TN2207, and TN2464 circuit
packs, and on DS1 Interface Media Modules.
The DS1-CO MO monitors and maintains a CO trunk port on a TN767 DS1 Interface circuit
