Completion of Call to Busy Subscriber (CCBS)
If the destination subscriber’s line is busy, the connection will be set up automatically
as soon as the external or internal destination subscriber terminates his call. The
CCNR feature must be enabled by the caller. When the destination subscriber hangs
up, the caller receives a call signal. Upon picking up the receiver, the connection to
the destination subscriber is established without any further dialling necessary. The
automatic connection is then complete.
Initiation of a CCBS depends on the kind of terminal used:
If a DTMF dialling terminal is used, the automatic call-back can be enabled
by entering the following key sequence(s):
o
enabling of CCBS:
o
disabling of CCBS:
If an ISDN terminal is used and if the CCBS feature is supported, the automatic
call-back feature can be enabled using a speed dialling key.
For further information, please consult the User's Manual of the ISDN terminal.
If an analogue terminal is used, you hear a positive confirmation tone as soon as the
CCNR request has been registered within the telephone system. In the event of an
error, you will hear an error tone. If the feature is not supported, you hear a negative
confirmation tone.
