Physical Description - Avaya Nortel Communication Server 1000 Reference

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 Communication Server 1000M and Meridian 1 Large System Installation and
Configuration (NN43021-310) for termination and cross-connect information.
The faceplate of the card is equipped with a red Light Emitting Diode (LED). When an NT8D14
Universal Trunk card is installed, the LED remains lit for two to five seconds while the self-test
runs. If the self-test is successful, the LED flashes three times and remains lit. When the card
is configured and enabled in software, then the LED goes out. If the LED flashes continuously
or remains weakly lit, replace the card.
