Reverse Circuit

Description
A circuit in the PBX can detect the reverse signal from the telephone company when an extension user tries
to make a trunk call. This detects the start (a called party goes off-hook) and end (the called party goes on-
hook) of an outgoing trunk call. When a trunk call is received, the circuit can also detect the reverse signal
after an outside caller goes on-hook.
The duration of a call can be verified on SMDR using this feature (→ 1.25.1 Station Message Detail
Recording (SMDR)).
It is possible to select whether the PBX detects the reverse signal for outgoing trunk calls only, or for both
outgoing and incoming trunk calls, or for no trunk calls (detection disabled) through system programming
(→ LCOT Reverse Circuit [415]).
