Assemblies ED7C723-35 Groups 1, 2 or 3
NOTE
:
This procedure consists of installing the E&M Customer Interface Cable
Assemblies (ED7C723-35 Group 1, 2, or 3) and mating their connectors to
the MDS Shelf Dangler Cable Assemblies (ED7C723-32 Groups 12 to 15,
Figures 3-40 and 3-41) which have been furnished as part of the MDS
assembly.
NOTE
:
Some pins on this 50 pin connector are not assigned. The rest are brought
out to the MDF for cross connections to subscriber derived pairs.
NOTE
:
This cable is available in varying lengths (Group 1, 2 and 3), however any
excess may be cut off to relieve cable rack congestion.
NOTE
:
VF channel numbering is from 1 to 96 for each MDS shelf. There are two
shelves per MDS Assembly (J1C265AB-1) with a total of eight shelves (4
assemblies) per 7 foot RT Bay (maximum of 768 quad channels). Each
shelf supports 96 channels with channel unit slots numbered CU1 to
CU24.
NOTE
:
System ID labels (furnished with the MDS Assembly) shall be filled out by
the customer in accordance with the route/system numbering scheme. The
MDF circuit labeling should follow this numbering pattern. Refer to the
APPLICATIONS chapter for typical cross-connect block numbering.
