3.22 The Data Interface Unit

The Data Interface Unit (DIU) is a device connected to a digital station port of a DSU. The DIU provides

connection for a digital multiline telephone and another device such as an Industry standard telephone

(IST), FAX, or modem. The DIU switches the voice path from the DSU to either the digital telephone or

the IST telephone by pressing a button on the digital telephone.

When the DIU is in the digital mode, the digital telephone will function fully and the IST telephone will

not function at all. When the DIU is in the IST mode, the IST functions fully and the digital telephone

will not have a voice path; however, the digital telephone will continue to receive LED and LCD

messages and send certain button messages.

The first step in any programming sequence is to enter the base level. Once in this mode, you can dial the

feature code for any desired configuration. Enter the base level with the following procedure: press

INTERCOM then dial ✳#746✳. When you want to end the programming, press the SPEAKER button

to end the programming procedure and return the system to normal operation.
