712 NT8D14 Universal Trunk card
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 222 "Connecting
paging equipment to the NT8D14 Universal Trunk Card (typical)" (page
714)
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.
