Circuit Card Description and Installation
3 If the NT5D97 card is being completely removed, not replaced, remove
data from memory.
4 Remove cross connections at MDF to wall-mounted cross-connect
terminal.
5 Tag and disconnect cables from card.
6 Rearrange Clock Controller cables if required.
7 Remove the DDP2 card only if both loops are disabled. If the other circuit
of a DDP2 card is in use, DO NOT remove the card. The faceplate switch
ENB/DIS must be in the OFF (DIS) position before the card is removed,
otherwise the system will initialize.
8 Pack and store the NT5D97 card and circuit card.
End of Procedure
Configuring the NT5D97
After the NT5D97 DDP2 is installed, configure the system using the same
procedures as the standard NT8D72BA PRI2.
Consider the following when configuring the NT5D97 DDP2 card:
• The CS 1000 Release 4.5 software allows four ports to be defined for the
NT6D80 MSDL. The DDCH (NTBK51AA) card has only two ports, 0
and 1; therefore, ports 2 and 3 must not be defined when using the
NTBK51AA.
CAUTION
Clock Controller cables connecting the Clock Controller and DDP2 card
must NOT be routed through the center of the cabinet past the power
harness. Instead, they should be routed around the outside of the
equipment shelves.
