Service protection center VF cabling
The CDS has four 25-pair connectors for line card T/R pair connection to the
VF protector blocks in the termination compartment. The connectors for VF
pairs 1 to 50 are located on the left-hand side of the CDS and the connectors
for VF pairs 51 to 96 are located on the right-hand side of the CDS. The
connectorized CDS cabling routes to the equipment side of the connectorized
VF blocks.
The CDS has the capacity to provide up to 96 lines of VF service. VF cable
pairs 97-100 are spare cable pairs in the second connector of the right-hand
side CDS.
Your cabinet may be equipped with either the NT4K12AA CDS or the
NT4K12AB CDS.
Figure 13-39 on page 13-63 shows the NT4K12AA CDS shelf connectors on
both the left and right sides for VF connection to the SPC. Figure 13-40 shows
the NT4K12AB CDS shelf connectors on both the left and right sides for VF
connection to the SPC. The figures show the VF line numbers for CDS 1. CDS
2-7 are numbered sequentially up to VF line count 672.
Each CDS is cabled to a VF protector block in the termination compartment.
The NT4K12AA CDS is cabled to the VF protector blocks with VF cables
NT4K87BD (CDSs 1-5), NT4K87BE (CDS 6) and NT4K87BF (CDS 7).
The NT4K12AB CDS is cabled to the VF protector blocks with VF cables
NT4K87BG (CDSs 1-5), NT4K87BH (CDS 6) and NT4K87BJ (CDS 7).
Figure 13-41 on page 13-65 shows the cabling connections from the CDS
shelves to the SPC VF protector blocks and to the cross-connect blocks (BIX
option shown).
Figure 13-42 on page 13-66 shows the cable routing from the CDS shelves to
