Circuit Card Description and Installation
Table 184 lists the signaling and trunk types supported by the NT8D14
Universal Trunk card.
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.
