The Inspiration can be equipped with an internal ISDN2
circuit, which can be used to optimise the use of your
ISDN2 lines. (When the Inspiration is equipped with 12
or more extensions, two internal ISDN2 circuits can be
provided).
Each of the ISDN 2 circuits can be equipped with eight
ISDN2 devices. Four of these can be powered from the
Inspiration. The remaining four, if equipped, must be
separately powered.
Eight extension numbers are allocated to each ISDN2
internal circuit. The first circuit is allocated extensions
120-127, the second either 130-137 or 140-147
depending on the build of the system.
Incoming calls are presented to the internal ISDN
circuits when one of the ISDN extension numbers is
programmed in the ringing group. If an appropriate
device is connected to the internal circuit, the call will
be presented to it.
It is recommended that MSN / DDI numbers are
programmed to ring the ISDN internal numbers so that
incoming calls will be routed directly to any device
which is programmed to respond to the extension
number.
