572 NT8D14 Universal Trunk card
The faceplate of the card is equipped with a red Light Emitting Diode (LED).
See
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.
The universal trunk card mounts in any IPE slot. 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 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.

announcement machines, paging equipment, and Central Office facilities,
connect to the card at the back of the Media Gateway using a 25-pin
connector. See the Communication Server 1000M and Meridian 1 Large
