Connecting paging equipment to the NT8D14 Universal Trunk Card (typical)
If the music source is equipped with contacts that close when music is
online, use these contacts to provide a ground to the MB line; otherwise,
ground the MB line at the MDF.A trunk unit can be connected to a music
source. The audio source should provide an adjustable power output at
600 ohms.
Configure units for music at the MUS or AWR prompts in the Trunk
Administration program LD 14 and assign routes at the MRT prompt in the
Trunk Route Administration program LD 16.
Music operation is similar to that of RAN in the continuous operation mode.
Connect the unit tip and ring leads to the audio source and ground the
CP line at the MDF. See
Figure 195 "Connecting RAN equipment to the
NT8D14 Universal Trunk Card (typical)" (page 582) .
