ISDN SERVICES
DESCRIPTION
The default dialing mode on ISDN lines is digit by digit. At the press of a key, users can employ block
dialing to access a range of services:
- addition of a sub-address to the number dialed
- activation of calling line identification restriction, i.e. the caller's identity is not transmitted to the
called party
- for a station with soft keys only, transmission of user-to-user signaling (UUS), i.e. a text message
on a station with a display.
The "Calling Line Identification Restriction" function can also be activated in digit-by-digit dialing
mode for all stations (see "Making/Answering a call").
When a call is received, the "malicious call identification" service is available service can be used.
This service, available by subscription to the network, involves the network operator recording certain
call details during the communication, (numbers of both parties; date and time of call; sub-address of
caller if applicable).
The keypad dialing features offer access (in transparent fashion) to the services provided by the pu-
blic network operator (the functional services of the particular operator).
