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 ( CPC Signal Detection—Incoming [420]) and for outgoing outside (CO) line calls ( CPC Signal Detection— Outgoing [421]).

•If a CPC signal is detected during a call between a caller using the DISA feature ( 1.15.6 Direct 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 ( CPC Signal Detection—Incoming [420]) specified through system programming ( Incoming Reverse [153]).
