Configure the NT5D12 DDP 153
CAUTION
Clock Controller cables connecting the Clock Controller
and NT5D12 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.
7 Determine if the other circuit of a NT5D12 card is in use.DO NOT
remove the card if in use.
8 Remove the NT5D12 card only if both loops are disabled. Switch
S1 (faceplate switch) must be in the OFF (DIS) position before the
card is removed.
9 Pack and store the NT5D12 card and circuit card.

Configure the NT5D12 DDP
After the NT5D12 DDP has been installed, it can be configured using the
same procedures as for the standard QPC720 PRI card.
Consider the following when configuring the NT5D12 DDP card:
• The system 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.
• Port 0 of the NTBK51AA can only be defined to work with Loop 0 of the
NT5D12 DDP card, and Port 1 of the NTBK51AA can only be defined
to work with Loop 1 of the NT5D12. This relationship must be reflected
when configuring a new DCH in LD 17 (in response to the DCHL prompt,
enter either 0 or 1 when specifying the loop number used by the DCH).
• You cannot define one of the NT5D12 loops for the NTBK51AA DDCH,
and the other loop for the QPC757 DCHI or the NT6D80 MSDL.
