Install Music-on-Hold Access

Requirements

An information outlet provides access to the music source. If the music source is Federal Communications Commission (FCC) registered, the switch side of the cross-connect field is connected directly to the switch cabinet.

If the music source is not Federal Communications Commission (FCC) registered to meet United States requirements, the switch side of the cross- connect field is connected to a 909A/B universal coupler. The 909A/B universal coupler is mounted in an auxiliary cabinet, if one is available.

If an auxiliary cabinet is not available, a connectorized wiring block must be locally engineered to replace the auxiliary cabinet ED-1E443-10 intra- connection panel.

The switch side of the cross-connect field is connected by the T and R leads to a TN763B/C/D auxiliary trunk circuit pack located in a port carrier. Other Auxiliary- Trunk circuit packs may be required in some countries.

Figure 9-27shows the connections for the Music-on-Hold feature when the loudspeaker equipment is Federal Communications Commission (FCC) registered. Figure 9-28shows the connections for the Music-on-Hold feature when the loudspeaker equipment is not Federal Communications Commission (FCC) registered.

The connections shown in Figure 9-27and Figure 9-28are used when the music source is not located in the equipment room. If the music source is located in the equipment room, the connections do not have to be routed through the cross- connect field.
