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.
