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).
*Proctor & Associates Company, Redmond WA
CAUTION
When you connect an adapter to an off-premise extension (OPX), you must install primary
protectors in series with the tip/ring pair of the telephone line that is routed to the OPX. This
action is necessary to protect both the user and the equipment from transient voltage spikes
that can travel through the cable. The telephone company offers basic protection against this
condition; however, that protection is usually designed to safeguard the central office circuits
and you cannot rely upon it to protect common equipment. To help insure that external
over-voltage surges do not damage the system, installation specialists recommend that you
install and properly ground gas discharge tubes or similar primary protection devices on the
telephone line that routes between the adapter and the OPX.
To install the OPX long loop adapter:
·Follow manufacturer’s instructions for unpacking, inspecting, mounting and wiring the
adapter unit.
·Plug a modular cable into the system jack on the adapter and connect the opposite end of
the cable to the IST jack on the ATI-D.
·Plug a modular cord into the telephone jack on the adapter and connect the opposite end of
the cord to the OPX line.
·Plug the adapter power cord into a standard 117 VAC, 3-wire electrical outlet.

							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 Standard Telephone
(IST), FAX, or modem-whichever one you will be connecting to the DIU.
2. Once you have selected the location for mounting the DIU, mark two locations for the
mounting screws as follows:
a. make the first mark,
b. measure 3 13/16 inches horizontally from the first mark and make the second mark.

							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 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 II 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 Programmingfor programming details.

							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.
·Connect the CID08-supplied cable between the CID08 and the COM2 serial data
connection on the common equipment.
·With the Caller ID Interface installed, you can also add two leads to provide the TD and SG
signals to a data printer or personal computer (PC). These leads are useful for adding caller
ID enhancement to the SMDA/SMDR printout or for providing messages in the ASCII
format suitable for use with PC-based applications programs.

							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
operation. Switches S2-1 through S2-5 set the baud rate, data bits, and parity, while switches
S2-6, S2-7, and S2-8 set the unit address for each device. Set the switches of the S2 per the
details shown in the following tables.
SWITCH S2-1 SWITCH S2-2 BAUD RATE
