2. MUSIC ON HOLD
2.1 Overview
This section will describe the installation of the 2743 to provide Music on Hold. This assumes
that you have a working 4-Line system. For information about the basic installation of the
Cortelco 4-Line system, see the 2740 or 2750 manual.
2.2 Phone Lines
Connect the 2743 jack labeled L1/L2 TO WALL to telephone Lines 1 and 2. This may be done
with one 4 wire line cord if the lines are wired to a two line RJ14 jack. If the lines are wired to
two single line RJ11 jacks a two-line coupler will be needed. Connect the 2743 jack labeled
L3/L4 TO WALL to telephone Lines 3 and 4.
2.3 DIP Switch
Set Switches 7 and 8 UP to activate Music on Hold.
2.4 Power
Connect the AC power adapter to the 12 VDC jack on the back of the 2743. This is shown as
Item 9 in the picture on Page 7. Plug the AC power adapter into a wall outlet. Please be sure this
outlet is not controlled by a switch.
2.5 Status Indicator
Verify that the status indicator (Item 8 Page 7) is blinking on and off rapidly. This shows that
power has been connected to the unit.
2.6 Music Source
2.6.1 Connection
Connect the music source to the Music Input Jack (Item 7 Page 7) using the audio cable supplied.
Note that the music source must have a 1/8 inch (3.5 mm) output jack. Plug one end of the cable
into the Music Input Jack on the 2743 and the other end into the output of the music source.
2.6.2 Device
Any music playback device (mp3 player, radio, tape player) with a 1/8 inch output jack may be
used as a music source. Also, cassette player with a continuous-loop tape may be used to
provide a personalized message instead of music.
