In most of the countries local network operators use the socalled “functional protocol” to control the following ISDN services:

1 Call Forwarding Unconditional (CFU)

2 Advice of Charge (AOC)

3 Hold, Consultation/Toggling (HOLD)

4 Three-party conference (3PTY)

The default settings of your Profiset 30isdn is preset to the functional protocol. If the above-mentioned ISDN services work correctly (page 12, 22, 23, 34), you should keep on controlling these services via functional protocol.

In some countries, however, keypad signalling is used to control the above ISDN services instead of the functional protocol. You will recognize that when it is possible to control the ISDN services by entering keypad sequences (e.g. *21#, *#21# a.s.o.).

To find out which ISDN services are controlled by keypad signalling in your country, contact your local network op- erator.

Handset is on-hook.

Start the programming procedure.

Enter the password if necessary.

Enter the code (1 ... 4) for the ISDN service.

Enter the code (0 or 1) for the signalling method.

Save the settings.

Note:

if you change the national variant (page 32), the signalling method for all ISDN services is set to functional protocol.
