Physical description

The NT8D09 can be installed in Slot 1, 2, and 3 of the Media Gateway, and
in Slot 7, 8, 9 and 10 of the Media Gateway Expansion.
A maximum of three analog line cards per Media Gateway and four analog
line cards per Media Gateway Expansion are supported.
The line card circuits connects to the backplane through a 160-pin connector.
The backplane is cabled to a connector in the bottom of the cabinet which is
cabled to the cross-connect terminal (main distribution frame) through 25-
pair cables. Station apparatus then connects to the card at the cross-connect
terminal.
The faceplate of the NT8D09 Analog Message Waiting Line Card is equipped
with a red LED which lights when the card is disabled. At power-up, the LED
flashes as the analog line card runs a self-test. If the test completes
successfully, the card is automatically enabled (if it is configured in software)
and the LED goes out.
