2. INSTALLATION
2.1. Overview
The 2742 is part of the 7 Series Multi-line phone system. Up to 16 instruments may be connected in
this system. All these devices use conventional telephone wiring. Total wiring runs between stations
may not exceed 600 feet.
2.2. Before Installation
In order to install your telephones correctly, you must determine the incoming wiring configuration. In
most cases, incoming lines will be terminated in either RJ-11 Single Line Jacks or RJ-14 Double Line
Jacks. If you are not sure of your incoming line configuration, contact your telephone line installer.
All connection between the wall jacks and the telephones should be done with the provided twisted pair
modular line cords. Please be sure that your modular cords have at least 4 wires in them. If you have
RJ-11 jacks, you will need two line adapters (not included) to connect to the 2742. These couplers
should be available where you purchased your 2742.
2.3 Initial Configuration
2.3.1 Standard Configuration
The 2742 is initially configured so that each line is common at all stations. In other words, Line 1 at
each telephone is connected to the same incoming line; Line 2 at each station is connected to the same
incoming line, etc. This is commonly known as a “square system.” If this is suitable for your
installation, you only need to connect the telephones to the telephone lines.
2.3.2 Private Lines
A private line is a telephone number that is connected to only one telephone in the system. No other
phones in the system have access to this telephone line.
2.3.3 Unconnected Lines
It is also permissible to leave one or more lines unconnected.
2.3.4 Line 1
Line 1 MUST be connected to the same incoming line on all phones for the system to function
correctly. Line 1 cannot be a DSL or VoIP line.
2.4. Desk Mount
a. Connect the power transformer to the jack on the back of the 2742. Plug the transformer into a
wall outlet which is not controlled by a wall switch. Use only a 9V DC 500mA, Class 2
transformer.
b. Connect the line cords. If you have RJ-14 line jacks, you need only connect 4wire line cords
between the wall jacks and the jacks in the base of the 2742. If you have RJ-11 line jacks,
you will need 2 line couplers as discussed in Section 3.3.2. Note that the jacks on the 2742
are numbered L1/L2 and L3/L4. Connect your incoming lines accordingly. Use the first two
jacks as Line In.

6
2.5. Wall Mount
a. Mount 2742 to the wall.
b. Connect the line cords as described above.
c. Connect the power transformer to the jack on the back of the 2742. Plug the transformer into a
wall outlet which is not controlled by a wall switch. Use only a 9V DC 500mA, Class 2
transformer.
2.6. Verify Proper Installation
This procedure should be used at each telephone after initial installation. It may also be used if you are
having problems with your system. First, verify the three items below at each telephone in the system.
a.. Verify that the AC power transformer is connected to the 2742 and to the mains power.
b. Verify that Line 1 is connected to the 2742.
c. Verify that a station number has been assigned. Go off hook on your cordless phone and dial
another station in your system (01 – 16). The phone should ring and display the incoming
station number. Note that this assumes that the system contains one or more 2740s or 2750s.
Now, verify that Line 1 has been connected correctly to all telephones.
d. Go off hook on your cordless phone and dial 81. Verify that the Line 1 LED is red at each other
station.
To verify the connection of lines 2-4, perform the following steps at each telephone. Note that this
assumes that all lines are connected to all telephones. Remember that Lines 2, 3, and 4 may not be
common.
e. For Line 2, go off hook on your cordless phone and dial 82. Verify that the Line 2 LED is red at
each other station.
f. For Line 3, go off hook on your cordless phone and dial 83. Verify that the Line 3 LED is red at
each other station.
g. For Line 4, go off hook on your cordless phone and dial 84. Verify that the Line 4 LED is red at
each other station.
Note: The cordless adapter will show lines that are seized by other 4 line units. This is shown by a red
led on the front of the unit.
