Group Number. A number that identifies the trunk group associated with the displayed data.

Group Type. The type of trunk associated with the accumulated data. The system monitors the following trunk types. For more information about these trunk types, see Administering Avaya Aura® Communication Manager.

• Access (access)

• Advanced Private Line Termination (aplt)

• Central Office (co) or Public Network Service

• Customer Provided Equipment (cpe)

• Digital Multiplexed Interface Bit Oriented Signaling (dmi-bos)

• Direct Inward Dialing (did)

• Foreign Exchange (fx)

• Integrated Services Digital Network (isdn-pri)

• Release Link Trunk (rlt)

Group Direction. Identifies whether the trunk group is incoming (inc), outgoing (out), or two-way (two).

Group Size. The number of administered trunks in a specified trunk group. For more information, see Avaya Aura® Communication Manager Hardware Description and Reference.

Group Member Number. The number that identifies a specific trunk member (in the group number).

The number of calls carried on the trunk member over the report interval (yesterday, today, or last hour). Wideband calls increment this counter once for every trunk or 64-kbps channel that they use.

Suggested actions:

• If the identified trunk member has zero or a very small number of calls (seizures) in comparison to other listed trunk members, use the Facility Test Calls feature to determine whether a specific trunk member is functioning.

• If a trunk is just suspected of causing problems, use the ACA feature to monitor the particular trunk group.

If any trunks in the trunk group are used in a wideband (n X DS0) connection, the system displays a W next to the trunk entry. In addition, the system also displays the W = Wideband Support tag in the report heading.
