Channel
An ISDN line, like an analogue telephone line, has two cables running into
your house but a distinction is made in ISDN between the two logical user
channels, known as the B-channels (which have nothing to do with the
physical cables) and the control channel, known as the D-channel.
Charge display
See AOC-D and AOC-E.
CLIP (Calling Line Identification Presentation)
Subscriber A calls subscriber B. The call number of A appears on B's
telephone display.
CLIR (Calling Line Identification Restriction)
The number of the calling line is not displayed.
COLP (Connected line identification presentation)
Subscriber A calls subscriber B. The call number of B is displayed on A's
telephone. If B has programmed call forwarding or deflection to C, then the
number dialed and the number transferred will not be the same; the call
number of C will be displayed, provided C has not suppressed his number.
COLR (Connected line identification restriction)
The call number of C is not displayed on A's telephone if C has set up COLR.
Conference call
See Three-party conference.
Consultation call
You are engaged in a call. You can use the "Consultation" function to interrupt
the call briefly to set up a second external call or internal call to another
subscriber. If you speak to the other person and then end the call, this was
a consultation call. If you switch back and forth between the first and second
parties, this is called toggling.
CW (Call Waiting)
See Call waiting
