Digital Telephone System
Making The Cable Connections
Four cable connections are required to the DIU—station line cord, digital telephone line cord,
IST/FAX/MODEM line cord, and power cable.
1. Disconnect the line cord on the digital telephone from the digital station port connector and
plug it into the connector labeled PHONE on the DIU.
2. Plug the line cord from the IST device you are installing with the DIU (such as a FAX
machine, or modem) into the DIU connector labeled FAX/MODEM.
3. Plug the transformer attached to one end of the power cable into a 115 VAC electrical wall
outlet. Connect the other end of the power cable into the DIU connector labeled POWER.
The green LED on the DIU will be on to indicate power is being supplied to the DIU.
4. Plug one end of a standard line cord into the connector labeled LINE on the DIU. Plug the
other end of the line cord into the digital station port connector.
NOTE: DIU power loss will create the same symptoms as the disconnection of the DIU from
the digital telephone system. If this occurs, plug the multiline digital telephone
directly into a digital station port connector.
Preparing The DSU For DIU Operation
Once you have verified that the system contains the correct software, you must program the
system for DIU operation. See Chapter 4, "System Programming" for programming details.
