Holding time is the elapsed time from when a trunk is accessed to the time a
trunk is released. When ACA is enabled through administration, the system
measures the holding time of each call.
A short holding time limit and a long holding time limit are preset by the System
Manager for each trunk group. The short holding time limit can be from 0 to 160
seconds. The long holding time limit can be from 0 to 10 hours. The measured
holding time for each call is compared to the preset limits for the trunk group
being used.
Measurements are not made on personal CO lines, out-of-service trunks, or
trunks undergoing maintenance testing.
Busy Verification of Terminals and Trunks
A multi-appearance voice terminal or attendant console equipped with a “verify”
button is required.
Busy Verification of Terminals and Trunks allows a user at a voice terminal or
attendant console to make test calls to trunks, voice terminals, and hunt groups
(DDC/UCD). These test calls check the status of an apparently busy resource.
This provides an easy method to distinguish between a voice terminal or
resource that is truly busy and one that only appears busy because of a trouble
condition.
Trunk Group Busy/Warning Indicators to
Attendant
An attendant console is required.
Trunk Group Busy/Warning Indicators to Attendant provides the console user
with a visual indication of the trunk group status for each trunk group associated
with the 12 Trunk Group Select buttons located on the console. Trunk groups with
busy indications during nonbusy periods should be checked to ensure that the
trunks are busy and not out-of-service. Use the Busy Verification of Terminals and
Trunks feature to test the suspected faulty trunks.
Trunk Identification by Attendant
A display-equipped voice terminal or an attendant console equipped with a
“trunk id” button is required.
Trunk Identification by Attendant allows a voice terminal or attendant console
user to identify a specific trunk being used on a call. This is useful when a user
experiences noise or poor transmission on a trunk call. The trunk identification
(access code and group number) is displayed when the “trunk id” button is
