7.14 Data Interface Unit
The Data Interface Unit, or DIU, is an optional external device that
may be part of your system installation. It provides connections for
both your telephone and an IST device such as a standard single-line
telephone, a FAX machine, a data modem, a cordless telephone, or an
answering machine.
If the installer has arranged your station in this manner, you can
switch between your telephone and the IST device by pressing the
DATA button that the installer has programmed on your telephone.
The light associated with the DATA button provides status indications
for your reference.
• To select your telephone if the DATA light is on or is
flashing,

the DATA button. If a call is in progress on the IST
device, it transfers to your telephone if you have your tele-
phone handset lifted or have your telephone in speakerphone
mode. If you do not, the call drops.
• To select the IST device if the DATA light is off,
—PRESS
the DATA button. If a call is in progress on your tele-
phone, it transfers to the IST device if the device is off-hook;
otherwise, the call drops. Your telephone still provides visual
messages and indications even though its voice path is routed
to the IST device.
