Calling Party Control (Cpc) Signal Detection - Panasonic KX-TDA100 Features Manual

1.9.10 Calling Party Control (CPC) Signal Detection

Description
The Calling Party Control (CPC) signal is an on-hook indication (disconnect signal) sent from
the analogue trunk when the other party is hung up. To maintain efficient utilisation of trunks,
the PBX monitors their state and when CPC signal is detected from a line, the PBX
disconnects the line and alerts the extension with reorder tone.
Conditions
• CPC signal detection is programmable for incoming trunk calls (
Detection Time—Incoming), and for outgoing trunk calls (
Time—Outgoing).
• If your telephone company sends signals similar to CPC, it is recommended not to enable
CPC signal detection on outgoing trunk calls.
• If CPC signal is detected during a Conference call, the line is disconnected. The
remaining parties stay connected.
• If CPC signal is detected during a call between a caller using the DISA feature and an
extension or an outside party, the line is disconnected.
