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.

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).
