Deactivating a control relay

Press the Talk key.

Call the system menu.

Select and confirm the menu item.

Select and confirm the menu item.

Follow the user guidance system from this point on- wards. Enter the required switch code (1... 4).

Press the On-hook key to end the process.

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 (Æ page 88).

You have an external connection.

Call the system menu.

Select and confirm the menu item.

Select and confirm the menu item.

Enter the service code and/or the 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).
