The digital line card supports voice only or simultaneous voice and data
service over a single twisted pair of standard telephone wiring. When
a digital telephone is equipped with the data option, an asynchronous
ASCII terminal, or a PC acting as an asynchronous ASCII terminal, can be
connected to the system through the digital telephone.
The NT8D02 Digital Line Card provides 16 voice and 16 data
communication links.
The NT8D02 Digital Line Card supports voice only, or simultaneous

asynchronous ASCII terminal, or a PC acting as an asynchronous ASCII
terminal, can be connected to the system through the digital telephone.
The 32 port NT8D02 Digital Line Card is supported in the Media Gateway
and Media Gateway Expansion. It can be installed in slots 1, 2, 3, and 4
of the Media Gateway and slots 7, 8, 9, and 10 of the Media Gateway
Expansion.
The 48 port digital line card is not supported in any configuration.
Physical description
The Digital Line card circuitry is mounted on a 31.75 cm by 25.40 cm
(12.5 in. by 10 in.) printed circuit board. The NT8D02 is a double-sided
PCB, whereas the NTDK16 is 4 layers, but standard thickness. Both cards
connect to the backplane through a 120-pin or 160-pin edge connector.
The faceplate of the NT8D02 Digital Line card is equipped with a red LED
that lights when the card is disabled. See
. When the card is installed, the LED remains
lit for two to five seconds as a self-test runs. If the self-test completes
successfully, the LED flashes three times and remains lit until the card is
configured and enabled in software, then the LED goes out. If the LED
continually flashes or remains weakly lit, replace the card.
Note:
The NTDK16AA has one LED. This LED shows the status of
Card 4. The NTDK16BA has three LEDs. These LEDs show the status
of Cards 4, 5, and 6 configured on the NTDK16.
The digital line card circuitry is contained on a 320 mm (12.5 in.) by 254
mm (10 in.) printed circuit board (PCB). The NT8D02 is a double-sided
PCB, whereas the NTDK16 is 4 layers, but standard thickness. Both cards
connect to the backplane through a 120-pin or 160-pin edge connector.
