NT8D02 and NTDK16 Digital Line cards

NT8D02 Digital Line card

The 32 port NT8D02 Digital Line card is supported in the Media Gateway and Media Gateway
Expansion.
You can install this card in any IPE slot.

NTDK16 Digital Line card

The NTDK16 is a 48 port card supported only in the Chassis system. It is based on the NT8D02
Digital Line card and is functionally equivalent to three NT8D02s, and configured as cards 4,
5, and 6 in the main chassis. It uses A94 Digital Line Interface chips (DLIC) to provide the
interface between the Digital sets and the system.
The NTDK16 Digital Line card can only be installed in slot 4 of the main chassis which is slotted
to prevent accidental insertion of other cards.The Digital Line Card is a voice and data
communication link between the system and Meridian Digital Telephones. It 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 or synchronous
terminal or personal computer can be connected to the system through the digital telephone.

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
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.
