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 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 32-channel mode is supported on the TN464C or higher suffix, TN2464 circuit packs, and on DS1 Interface Media Modules.
The DS1-CO MO monitors and maintains a CO trunk port on DS1 Media Modules. Throughout this discussion, the term DS1 applies to all. For more information, see one of the following maintenance objects:

The DS1 circuit pack or media module supports low level CO trunk signaling interfaces for both ground-start and loop-start trunks.
Three trunk service states are specified by DS1 CO trunk maintenance:
out-of-service |
The trunk is in a deactivated state and cannot be used for either incoming or outgoing calls. |
in-service |
The trunk is in an activated state and can be used for both incoming and outgoing calls. |
disconnect ready-for-service |
The trunk is in an activated state but can only be used for an incoming call. |
