Physical description

The trunk and common multiplexing circuitry is mounted on a 31.75 cm by 25.40 cm (12.5 in. by 10 in.) printed circuit board.

The NT8D14 Universal Trunk card connects to the backplane through a

160-pin connector shroud. The backplane is cabled to the I/O panel, which is cabled to the Main Distribution Frame (MDF) by 25-pair cables. External equipment, such as recorded announcement machines, paging equipment, and Central Office facilities, connect to the card at the MDF.

See the Communication Server 1000S: Installation and Configuration (553-3031-210) for termination and cross-connect information.
