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 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 channels on a 1.544-Mbps link
● 31 DS0 channels + 1 framing channel on a 2.048-Mbps link

The DS1-CO MO monitors and maintains a CO trunk port on a TN767 DS1 Interface circuit
pack, a TN464 UDS1 Interface circuit pack, or on DS1 Media Modules. Throughout this
discussion, the term DS1 applies to all. For more information, see one of the following
maintenance objects:
Circuit Pack/Media Module Maintenance Object

TN464 UDS1 Interface Circuit Pack UDS1-BD
DS1 Interface Media Modules MG-DS1
The DS1 circuit pack or media module supports low level CO trunk signaling interfaces for both
ground-start and loop-start trunks.
