1.11.10 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 hangs up. To maintain efficient utilisation of trunks, the PBX monitors their state
and when CPC signal is detected from a line, disconnects the line and alerts the extension with a reorder tone.
Conditions
•
CPC signal detection is programmable for incoming trunk calls, and for outgoing trunk calls.
•
If your telephone company sends other signals similar to CPC, it is recommended not to enable CPC signal
detection on outgoing trunk calls.
•
If a CPC signal is detected during a Conference call (
®
1.14.1.2 Conference), that line is disconnected,
but the remaining parties stay connected.
•
If a CPC signal is detected during a call between a caller using the DISA feature (
®
System Access (DISA)) and an extension or an outside party, the line is disconnected.
