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 Trunkcard connects to the backplanethrough 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.Each unit on the
card connects to the backplane through an 80-pin connector,the backplane
is cabled to the Input/Output (I/O) panel, and the I/O panel is cabled to
the cross-connect terminal. At the cross-connect ter minal, each unit
connects to external apparatus, such as Central Office facilities or recorded
announcement equipment. Each unit connects to external apparatus by tip
and ring leads which carry voice, ringing, tone signaling, and battery.
See the Communication Server 1000M and Meridian 1 Large System
Installation and Configuration (NN43021-310) for termination and
cross-connect information.
