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 Route Data Block 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. 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.
