1.10.9 Calling Party Control (CPC) Signal Detection

Description
The Calling Party Control (CPC) signal is an on-hook indication (disconnect signal) sent from a CO line
when the other party hangs up. To maintain efficient utilization of CO lines, the PBX monitors each line's
status and when 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 CO line calls (→ LCOT CPC Signal Detection
Time—Incoming [414]), and for outgoing CO line calls (→ LCOT CPC Signal Detection Time—
Outgoing [413]).
• If your telephone company sends signals similar to CPC, it is recommended not to enable CPC signal
detection on outgoing CO line calls.
• If CPC signal is detected during a conference call (→ 1.13.1.2 Conference), the line is disconnected.
The remaining parties stay connected.
• If CPC signal is detected during a call between a caller using the Direct Inward System Access (DISA)
feature (→ 1.15.6 Direct Inward System Access (DISA)) and an extension or an outside party, the line
is disconnected.
