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.
