OPTIONALEQUIPMENT CONNECTION
270.1 MUSIC ON HOLD
Provision has been made to allow connection of a
locally provided external music source to provide
Music On Hold for held calls.
Music source input is made using the phono jack
MOH
located on the TSW-E( ) ETU. For music source input
level and impedance, refer to Section 220.20 of this
document.
NOTE:
In compliance with FCC Part 15 regulations,
the following procedure must be implemented
any time a Music On Hold source is connected
to this system.
A. Make a slit on the cable insulation approximately
one and one half inches long, at a distance of 12
inches from the plug end, on the cable to be
connected to the TSW-E( )
MOH
jack.
Take special care not to cut into the shield wire and
inner wire insulation.
Make a circular cut in the cable insulation at one
end of the slit.
Pull the cut insulation from the cable to expose
the shield for the length of the slit and cut the
insulation off.
Bend the cable near the middle of the exposed
shield and separate the shield from the inner
insulation in preparation for soldering, refer to
Figure 200-51.
Obtain a 7 inch length of 20 - 24 AWG stranded
wire and connect a ring tongue type connector at
one end.
Strip a + inch length of insulation from the other
end of the 7 inch wire. Solder this end to the
shield previously exposed in step C, place tape
around this connection to prevent the possibility
of any unwanted short circuits.
Connect the plug end into the TSW-E( )
MOH
jack.
Route the cable down and to the right side of the
CCU to avoid interference with the insertion and
the removal of ETUs. Exit the other end of the
cable at the right rear side of the CCU.
