NTDK16BA - 48 Port Digital Line Card
The NTDK16 is a 48 port digital line card, which is supported only in the Chassis (NTDK91) system: 11C mini or CS1000e - it is not compatible with the MG 1010E chassis. Functionally equivalent to three 16 port NT8D02's, and configured as cards 4, 5, and 6 in the main chassis. There are 3 status LED's, one for each equivalent NT8D02 (L4, L5, L6).
The NTDK16 Digital Line Card (DLC) can only be installed in slot 4 of the main chassis which is keyed to prevent accidental insertion of other cards (the chassis does not have physical slots 5 and 6). Circuits are presented on 2 Amphenol connectors, each with 24 ports.

Note: The NTDK16AA 48 port card is similar, but has just one faceplate LED. This LED shows the status of Card 4 only.
Programming:
Add a Multi-line Telephone Line Card (CARDMLT) on three card slots: 4, 5 and 6 in LD 11:
REQ: new
TYPE: cardmlt 0 0 4 this is a 48 port digital card...
so, repeat for TN 0 0 5, and TN 0 0 6
CTYP <enter>
It behaves just like three separate NT8D02 digital line cards, therefore LD 11: NEW, CHG, OUT, STAT, ENLC, DISC, etc.
Amphenol pinout:
There is half a card 6 (8 TN's) on each 'Card 4/6' and 'Card 5/6' amphenol. The punch-down BIX label is as follows:
