Applications
The optional applications, features, and signaling arrangements for each
trunk are assigned through unique route and trunk data blocks.
Paging trunk operation
A universal trunk card unit can be configured as a paging trunk. Configure
units as paging trunks in the Trunk Data Block program LD 14 and assign
routes in the Route Data Block program LD 16.
Figure 141 on page 625 shows a typical connection from customer-provided
equipment to unit 0 on a universal trunk card that can be installed in slots 1,
2, and 3 in an MG 1000S, and slots 7, 8, 9, and 10 in an MG 1000S. See
Communication Server 1000S: Installation and Configuration
(553-3031-210) for trunk wiring information.
Music operation
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.
