8.1 Music on Hold
The system can provide Music on Hold from either an internally synthesized
source on the GCD-CP10 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.
In addition to a connector on the GCD-CP10, the
PGDAD
s also provide
connections for external MOH sources. When using external music sources for
external MOH, programming determines the MOH source for each trunk.
The GCD-CP10 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 external 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 0.5A
(the relays are normally open and close when a call is put on hold).
8.2 Installing External Music on Hold
To connect to the GCD-CP10
1. Connect an RCA line from the AUX1 or AUX2 connector on the GCD-CP10
to the appropriate location 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.
