Sending a signal to the network

To enable ISDN-type services/ features to be started via
analog lines (e.g. call waiting when a line is busy, three-
way conference calls, etc.), you must send a signal to
the network before dialling the service code and/or
phone number.
This function can also be called directly by entering the
code ( page 88).

External call forwarding with a multi-
ple subscriber number
If your communication system is connected to an ISDN
multiple device line, then you can forward all incoming
calls from the public network through your multiple sub-
scriber number (MSN) to an external destination.
There are three types of forwarding:
• Calls are forwarded immediately (1=immediate call
forwarding).
• Calls are forwarded after a certain time (2=unan-
swered calls).
