1.10.10 Calling Party Control (CPC) Signal Detection

Description
A CPC (Calling Party Control) signal is an on-hook indication (disconnect signal) sent from an outside (CO)
line when the other party hangs up. To maintain efficient utilisation of outside (CO) lines, the PBX monitors
each line's status and when a CPC signal is detected on a line, the PBX disconnects the line and alerts the
extension with a reorder tone.
Conditions
• CPC Signal Detection is programmable for incoming outside (CO) line calls (
Detection—Incoming [420]) and for outgoing outside (CO) line calls (
Outgoing [421]).
• If a CPC signal is detected during a call between a caller using the DISA feature (
Inward System Access (DISA)) and an extension or an outside party, the call will be disconnected.
• It is possible to select whether the PBX detects the reverse signal from incoming outside (CO) line calls
for the duration (
Incoming Reverse [153]).
