In the Paging mode, the Universal Trunk is connected to a
customer-provided paging amplifier system. When the trunk is accessed
by dial-up or attendant key operation, it provides a loop closure across
control leads A and B. In a typical application, it transfers the input of the
paging amplifier system to the transmission path of the trunk.

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 206 "Connecting

paging equipment to the NT8D14 Universal Trunk Card (typical)" (page

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 a
Media Gateway and slots 7, 8, 9, and 10 in a Media Gateway Expansion.
See Communication Server 1000M and Meridian 1 Large System
Installation and Configuration (NN43021-310) 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.
