Comdial Dsu II Digital Telephone System Instructions Manual

Installing An OPX Long Loop Adapter To
The Analog Terminal Interface For Off-Premise Service
As stated previously, the analog terminal interface is an on-premise device. You must use an
OPX long loop adapter if you wish to adapt the ATI-D to support an off-premise application. An
OPX long loop adapter connects to a single telephone line and can greatly extend the line’s loop
length (the Proctor Model 46222 adapter*, for example, can extend line length to 30,000 feet).

2.18.3 Installing The Data Interface Unit
Unpack the Data Interface Unit (DIU) and check for the following parts:
·Telephone line cord
·Power cable with attached transformer.
Installing The Mechanical Components
You can install the DIU in either a free-standing manner or you can mount it on a wall.
When mounting the DIU on a wall:
1. Select a location that is close to a standard 115 VAC electrical wall outlet. The location you
select should also be convenient to the digital telephone and the Industry...

3. Install two #8 X 3/4-inch screws in the wall at the locations you marked in step 2. Tighten
the screws until the screw heads are 1/4-inch from the surface of the wall.
4. Place the DIU on the wall with the screw heads inserted into the slots provided on the bottom
surface of the DIU. Slide the DIU onto the screw heads until it is firmly attached to the
screws.

Making The Data Interface Unit 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...

2.18.4 Supporting Caller Identification Service
You can provide Caller ID information through the serial data port COM2 using the Caller ID
Interface (product code CID08) and a special equipment-supplied cable. Caller ID information
for incoming calls shows on the displays of the system’s LCD speakerphones.
Make the connections that are detailed in the following statements.
·Connect the CO lines providing Caller ID data to both the common equipment and the
CID08 line jacks in the same numerical order....

Setting The Caller ID Parameter Switches
The Caller ID device has two banks of parameter switches located on its front panel.
Set the switches of the S1 switch bank per the following rule:
·If you are combining units (more than 8 lines are used), turn all switches in Dip Switch S1
OFFexcept for switch 7. Turn S1 switch 7ONwhen combining units. If you are not
combining units, turn all S1 switchesOFF.
You must set the switches of the S2 switch bank in a certain manner to enable Caller ID
