NT8D14 Universal Trunk card

See

Table 264 "Pad switching algorithm" (page 708)

for the pad switching

control for the various through connections and the actual port-to-port loss
introduced for connections between the NT8D14 Universal Trunk Card and
any other port designated as Port B.

Note 1: Transmit and receive designations are from and to the CS 1000. Transmit is from the CS
1000 to the external facility (digital-to-analog direction in the Universal trunk card). Receive is to the
CS 1000 from the external facility (analog-to-digital direction in the Universal trunk card.

Note 2: When Port B is the call originating port and if the Universal trunk card is the originating port,
the UTC pads are out and the Port B (PE CO/FX/WATS) pads are in.

Applications

The optional applications, features, and signaling arrangements for each
trunk are assigned through unique route and trunk data blocks.

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 220 "Connecting paging equipment to the NT8D14 Universal
Trunk card (typical)" (page 711)

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
