Signalling method to control the ISDN services
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.
