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.

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 Figure 101 on page 517. 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.
