BT Revelation
ISDN Access Unit
The connection of the BT Revelation ISDN
Access Unit to a BT Revelation System with
a minimum configuration of 2+6 provides
ISDN2 voice services to all devices
connected to your BT Revelation system.
The fact that some or all of the lines
connected to your BT Revelation are ISDN2
lines does not affect how you use the features
and facilities which appear in this BT
Revelation
Owner's Handbook.
The connection of the ISDN Access Unit will
not affect the other ISDN services supported
on your ISDN2 lines.
You may keep all your existing analogue
equipment (such as fax machines, answering
machines, cordless phones etc). These will
then be used over the ISDN circuits via your
BT Revelation.
Using your BT Revelation with
ISDN
The ISDN Access Unit is designed so that it
can
be
connected in parallel with any other ISDN
device (for example, a
data
application,
PC
or
group
4
fax).
Your BT Revelation system
will
only react to voice calls, as it assumes that
all
other calls (ie
data
calls)
are
destined for
another device on the ISDN2 line.
If other equipment is connected in parallel,
you will notice that when a device is using an
ISDN2 line, the light on the Systemphones
beside the key corresponding to the line,
glows red.
If
an incoming call is answered by
another device on the So bus, the
Systemphone light may not indicate that the
line is busy.
