MUSIC SOURCES

Music on Hold (Figure 4-19, Figure 4-20)

The system can provide Music on Hold from either an internally synthesized source on the CPU or from an
external source. The external MOH can be a tuner, tape deck, CD player, etc. The settings in Program 10-04-
01 and 14-08-01 determine whether the source for MOH is internal or external (refer to the Software Manual
for further details).
In addition to a connector on the CPU, the 2PGDAD modules also provide connections for external MOH
sources. When using external music sources for external MOH, programming determines the MOH source
for each trunk. Refer to Music on Hold in the Software Manual for more details.
The CPU provides a dry relay that activates when a call is placed on Hold. When an external MOH source is
connected to the MOH relay and a call is placed on Hold, the MOH relay is activated. This allows an exter-
nal relay sensor/power supply to turn on the MOH source.
This arrangement allows the MOH source (e.g., a tape deck) to run only when a call is placed on Hold. The
maximum applied voltage for the relay is 24vDC at .5A (the relays are normally open and close when a call
is put on hold).

Installing External Music on Hold

1. Connecting to the CPU:
Connect an RJ61 modular line cord from the CN23 connector on the CPU to the appropriate loca-
tion on the extension cross-connect block.
2. Connect the two-conductor station cable from the cross-connect block to the external music source.
3. Install bridging clips as required.
OR
1. Connecting to the 2PGDAD Module:
Make sure the jumper in the 2PGDAD module for the channel is set correctly. (Refer to Figure 4-4
JUMPER SETTINGS on page 4-3).
2. If a line cord was not previously connected to the 2PGDAD, complete Steps 3-6. Otherwise, skip to
Step 7.
3. Install a modular jack for each 2PGDAD module. For each module, run one-pair 24 AWG station
cable from the cross-connect block to a modular jack. Ground the unused pair.
