Data Assignment
Use Memory Block 1-8-08 (Class of Service (Station) Feature
Selection 2), Page 6: LK 4, to assign Supplementary Services access
to stations via Feature Class of Service.
Use Memory Block 1-1-85 (ISDN Stimulus Method Selection) to
specify whether the system is being used in Australia or New Zealand.
Use Memory Block 3-72 (ISDN BRT Connection Configuration) to
assign the BRT interface as Point-to-Point or Point-to-Multipoint
(default: Point-to-Multipoint).
General
This feature provides access to various Supplementary Services
provided by the ISDN network only. BRI or PRI ISDN trunks must
therefore be installed in the system.
Depending on the ISDN network to which you are connected, there
may be no service tones returned from the network upon setting a
feature. The Xen IPK system does not provide tones or any other
indications to indicate feature status.
Performing the procedure on a station for which the setting of
Supplementary Services is not allowed by the Class of Service, does
not allow the user to activate supplementary services.
Pressing the Supplementary Services Key or performing the
procedure to disconnect the line during the setting of Supplementary
Services enables the user to exit from this mode.
Supplementary Services can be assigned to a Line Key assigned as a
one-touch or a DSS key. However, it must not be registered twice on
the same handset.
The Supplementary Services key can be registered only on a station
allowed by the Class of Service. The Supplementary Services key
already registered is retained however if it is then restricted by Class of
Service.
When the Supplementary Services key is pressed other than while
seizing an ISDN trunk, it will respond depending on the type of key to
which it has been allocated; One-touch key = ERROR displayed; DSS
key = None displayed.
