Chapter 2 - Features and Operation
CO Line - Loop Supervision
Description
The Triad-S can be programmed to monitor CO lines while on-hold or connected to RAN
devices or Voice Mail systems, or in Trunk-to-Trunk connections for disconnect signal
provided by the Telco. After a disconnect signal is detected, the
Triad-S releases the CO lines
and automatically place them back in service.
Loop Supervision Programming
Description
Loop Supervision is used primarily with DISA, Voice Mail/Auto Attendant and with
unsupervised conference applications. It lets the system detect when loop current is broken
and an outside line is no longer being used. To determine timer value for loop supervision,
consult your local central office for type and duration of loop supervision signal.
