ISDN
Where the PBX is equipped with ISDN line(s), ISDN can be used to automatically back up the
on-board ADSL modem in the event of line failure. In the case where no broadband service is
available, ISDN can be used for Internet access. The default setting is that ISDN is disabled.

• Select “Change the ISDN settings here …”
Three options are presented for using ISDN :-
(1) Disabled
With this option, ISDN is never used to establish an Internet connection. This is the default
setting.
(2) Backup
When this option is enabled, ISDN is used to automatically backup the on-board ADSL
modem in the event of line failure. When a line failure is detected, ISDN will wait 60 seconds
before backing up ADSL. When the ADSL line is restored, the ISDN call will be automatically
disconnected and browsing resumed over ADSL.
