ISDN SERVICES CALL SERVER : TELEPHONE FEATURES
Ed. 044/4 Réf. 3EH 21000 BSAA
KEYPAD DIALING FEATURES
In certain countries, the public ISDN operator provides services that can be activated using the ETSI
ETS 300 122 protocol (in addition to these generic services, each public operator defines how these
services are handled in their national specifications).
To access these services, the system establishes transparent communications between the public ex-
change and the internal users, who can then key in codes and receive a response from the public ex-
change.
This service is available with all station types on an Alcatel OmniPCX system directly connected to the
public exchange (not through a private network).
To activate the service:
- with the station in idle, dial the ISDN trunk group seizure code
- press * or #
- dial the service code (22 digits maximum) or press a key programmed with this code. The response
from the public exchange is displayed for 5 seconds.
