Sending a signal to the network

To enable ISDN-type services/ features to be started via
analog lines (for example, 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 by entering the code

External call forwarding with a
multiple 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).
• Calls are only forwarded when the line is busy
(3=when busy).
