NT8D02 and NTDK16 Digital Line cards
553-3001-211 Standard 3.00 August 2005
The Digital Line card provides 16 voice and 16 data communication links.
NT8D02 Digital Line card
The 32 port NT8D02 Digital Line card is supported in the MG 1000S and
MG 1000S 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.
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 104 on
page 529
. 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.
