C 3 Features
3-32 Features *: Available for KX-TD1232 only.
the extension user remains off-hook after the completion of an outgoing
outside call, the system does not release all the switches used to
establish the connection, and a CO line connected will continue to be
seized. To prevent this, it is administrable to make CPC Signal
Detection work on outgoing outside calls. (Note: Some Central Offices
may send CPC-like signals during the dialing sequence and an attempt
to make a call may be terminated. If your CO does not send such
signals, it is recommended to make CPC Signal Detection work on
outgoing outside calls.)
• CPC Signal Detection is effective only with the 4-DID Line Unit (KX-
TD185) (KX-TD816: CO05 through CO08, KX-TD1232: CO09
through CO12 or CO21 through CO24). In this case, “D (4DID)” must
be selected in program [109] “Expansion Card / Unit Type.”
• If your Central Office does not send CPC-like signals, it is also
effective to limit the dialed numbers during a call by the program [991]
“COS Additional Information” on a Class of Service basis to prevent
unauthorized calls.
• If CPC Signal is detected during a Conference call, the line is
disconnected and the remaining two parties maintain the call.
