Automatic Circuit Assurance
A display-equipped voice terminal (may be nondisplay type if the Voice Message
Retrieval feature is provided) or an attendant console is required. An "ACA
activate/deactivate" button (one per system) is required on the voice terminal or
attendant console.
Automatic Circuit Assurance (ACA) assists users in identifying possible trunk
malfunctions. The system maintains a record of the performance of individual
trunks relative to short and long holding time calls. The system automatically
initiates a referral call to an attendant console or display phone when a possible
failure is detected.
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.
