Attendant Control of Trunk Group Access
Attendant Control of Trunk Group Access allows the attendant to control trunk
groups, and prevents telephone users from directly accessing a controlled trunk
group. The attendant gains direct access to an outgoing trunk group by pressing
the button assigned to that trunk group.
Each attendant console has 12 designated Trunk Hundreds Select buttons that can
be administered for Attendant Control of Trunk Group Access. You can also
administer each console with up to 12 feature buttons for Trunk Hundreds Select
buttons, which gives you up to a total of 24 buttons.
Each Trunk Hundreds Select button has busy lamps that light when all the
members of the associated trunk group are busy. If you administer one of the
2-lamp feature buttons on a basic console as a Trunk Hundreds Select button, use
the bottom lamp as the busy lamp. These buttons have 2 additional lamps for
Attendant Control of Trunk Group Access. The 2 lamps are:
■ Warn (warning) lamp
Lights when the administered number of trunks are busy in the associated
trunk group. You administer the Busy Threshold field on the associated
Trunk Group screen to determine when to light this warning lamp.
■ Cont (control) lamp
Lights when the attendant activates Attendant Control of Trunk Group
Access for the associated trunk group. Assign act-tr-grp and deact-tr-g
buttons on the Attendant Console screen to allow the attendant to activate
and deactivate control of the trunk group access.
Interactions
■ Authorization Codes
Authorization codes do not collect when a trunk group has an incoming
destination set to the attendant.
■ Automatic Route Selection and Automatic Alternate Routing (ARS/AAR)
Activating Attendant Control of Trunk Group Access removes the
controlled trunk groups from the ARS and AAR patterns. Deactivating the
feature reinserts the groups into the patterns. ARS calls do not route to the
attendant.
■ QSIG
QSIG trunks do not support Attendant Control of Trunk Group Access.
■ Uniform Dial Plan
Activating Attendant Control of Trunk Group Access removes the
controlled trunk groups from preferences. Deactivating the feature enables
the UDP to access the trunk groups.
