<strong>DSU</strong><strong>II</strong> LCD Speakrphone User’s Guide<br />
The Data Interface Unit, or DIU, is an optional external device that<br />
may be part of your system installation. It provides connections for<br />
both your telephone and an IST device such as a standard single-line<br />
telephone, a FAX machine, a data modem, a cordless telephone, or an<br />
answering machine.<br />
If the installer has arranged your station in this manner, you can<br />
switch between your telephone and the IST device by pressing the<br />
DATA button that the installer has programmed on your telephone.<br />
The light associated with the DATA button provides status indications<br />
for your reference.<br />
