The Calling Party Control (CPC) Signal is an on-hook indication
(disconnect signal) sent from the outside (CO) line when the
telephone is hung up at the other end. To maintain efficient
utilization of outside (CO) lines, the system monitors their state and
when a CPC Signal is detected from a line, the system disconnects
the line and alerts the extension with a reorder tone.
• CPC Signal Detection is enabled or disabled for incoming and outgoing
outside calls by system programming.
• Generally, CPC for Signal Detection works for incoming outside calls,
and does not work for outgoing outside calls (except after they are
placed on Call Hold or Exclusive Call Hold). In this case, if an
extension user remains off-hook after an outgoing outside call is
completed, the system will not release all the switches used to establish
the connection. The connected outside (CO) line will continue to be in
use. To prevent this, CPC Signal Detection can be programmed to work
for outgoing outside calls.
• If a CPC Signal is detected during a Conference call, the line will be
disconnected and the remaining two parties can resume their call.
• If a CPC Signal is detected during a call between a DISA caller and an
extension or external party, the line will be disconnected.
