2-4   Issue 2   July 1997 In addition to the back panel connections, a three-color light-
emitting diode (LED) is visible through the top of each unit and
provides information about the status of the equipment.
Installation Procedure
Installing the Remote Module involves connecting the line cords,
the telephone cord, the power cord, and, at your option, the
RS-232 cable. The line cord and power cord are supplied with your
Remote Module, and the telephone cord and any power cords
required for the operation of the telephone are supplied with the
display telephone.
Follow these steps to install the Remote Module:
! CAUTION:
Do not plug the A/C adapters into the electrical outlets until
instructed to do so in the following procedure.
1. Ensure that the module has the proper DIP switch configuration
(see Table 2-1). 
						

							Installation
Issue 2   July 1997   2-5
Table 2-1.  DIP Switch Configuration
Switch # OFF ON
1 Normal operation Reserved
2 Normal operation Dedicated lines
3 Normal operation Reserved
4 Normal operation Test mode
NOTE:
If you are using a standard central office line, you do not have to
change the factory-set DIP switches. Check with your system
administrator before making any changes. Your system
administrator may have changed DIP switch 3 to the ON
position for normal operation. 
Do not change this setting without
contacting your system administrator.
2. Connect one end of the line cord provided with the Remote
Module to the telephone company phone jack and the other end
to the LINE jack of the Remote Module.
3. Connect the DEFINITY telephone to the PORT jack of the
Remote Module by using the cord provided with the telephone.
! CAUTION:
Do not plug the line cord  provided with the Remote Module
into the PORT jack of the Remote Module. Damage to
circuits may result.

2-6   Issue 2   July 1997 4. Connect the AC adapter provided with your system to the
Remote Module. Plug the adapter into a standard 120-vac
electrical outlet.
! CAUTION:
Do not plug the A/C adapters into a 240-vac outlet because
you will damage the adapter and the module. You must first
obtain an adapter to convert 240 vac to 120 vac.
5. The display on the telephone will initialize and read “Go
Online?”
Connections for Data Transmission
By using the COM 1 port on the Remote Module, you can establish
simultaneous data transmission between the off-premise location
and the on-premise location. Typically this involves a personal
computer (a “remote data terminal”) at the off-premise location
communicating with an RS-232 server link on-premise (at the
DEFINITY ECS location).
You will need two straight-through, 9-pin RS-232 cables to
establish data transmission.
Connect the data terminal at the remote location to the COM 1 port
of the Remote Module by using the straight-through cable (see
Figure 2-2). 
						

							Installation

Figure 2-2.  RS-232 Cable Pin Connections
NOTE:
The DEFINITY Extender modules use the CTS line for flow control.
When the internal buffer is 32 characters from full, the CTS line is
turned off. While CTS is off, up to an additional 32 characters can
be transmitted without any loss of data. If hardware flow control is
not enabled or if a cable without the CTS line connected is used,
characters will be lost when this buffer overflows.
The DEFINITY Extender modules use the DCD line to indicate
whether or not the modules have made a connection. When this
line is on, the modules have made connection.

How to program the operating parameters for the DEFINITY®
Extender Remote Module
Before you can use the Remote Module, you must program the
operating parameters, such as the phone number, the type of dialing,
and the baud rate of communication.

Using the Telephone for
Programming
Use the DEFINITY telephone to program the operating parameters
at the remote location. Prompts will appear on the telephone
display. To respond to the prompts, press the dial pad keys on the
telephone. Table 3-1 shows the keys used to move to or select
programming options.
Table 3-1.  Telephone Keys Used in Programming
Telephone Key Function
1 Allows user to move backward through
programming menu.
2 Allows user to select a parameter for
programming.
3 Allows user to move forward through
programming menu.
After you connect your Remote Module and DEFINITY telephone,
the following will appear on the telephone display: 
						

							Programming
Issue 2   July 1997   3-3
To begin programming, press 3 until the first parameter (“Set
Phone Number?” ) is shown on the display. If your system
administrator preprogrammed your Remote Module, press 
2 to
begin system operation (see Chapter 4, Operating the DEFINITY
Extender.)
Setting the Telephone Number
If your Remote Module is connected to a standard telephone line, a
telephone number to dial must be programmed for proper
operation. If your system administrator has not preprogrammed this
telephone number for your Remote Module, follow the steps and
screens below to set the telephone number on the module. The
following screen appears only if the module is configured for 
dial
line
 operation (DIP switch 2 is OFF). This parameter programs the
telephone number used to call the Switch Module. Ask your system
administrator for the telephone number to program.
1. Press 2 to select this parameter, or press 3 to advance to the
next programming option. If you select 
2, either a screen
appears showing the current stored number or a blank screen
appears if no number has been programmed.
2. To change an existing number or to enter a new number, dial
the required digits by using the telephone keys (0 to 9).
3. Press the Drop button on the display telephone to accept the
number and return to the main menu.

Setting the Mode of Dialing
The options for the mode of dialing (tone or pulse) appear only if
the Remote Module is configured for 
dial line operation (DIP switch
2 is OFF).
Setting Pulse Dialing
Follow these steps to set the mode of dialing to pulse:
1. At the “Go Online?” screen, press 
3 until the following screen
appears:
2. “Set Pulse Dialing” indicates that TONE dialing is presently
activated (factory default). If you want to switch to PULSE
dialing, press 
2. The following screen appears:
3. Press 2 to accept the change or 1 to cancel the request.

Setting the Connect Rate
Setting the Connect Rate establishes the baud rate in kilobits per
second (kbps) for the communications between the Switch and
Remote Modules. Follow the steps and screens below to set the
Connect Rate.
1. At the “Go Online?” screen, press 
3 until the following screen
appears:
2.Press 2 to change the connect rate. The following screen
appears:
3. Press 3 until the Connect Rate you want appears. There are
six choices:
nAuto—(Factory default). When the auto setting is selected,
the module tries to connect at the speed that will provide
the best performance with the fewest errors. The speed will
vary depending on line performance. If the module is
unable to connect at any of the available speeds, an error
message appears.
nF-- —The Remote Module will connect at 19.2 kbps only,
the fastest rate.
