Installation Procedure for Cable
Assemblies ED7C723-37 Groups 4 to 9
NOTE:
This procedure consists of installing the VF Customer Interface Cable
Assemblies (ED7C723-37 Groups 4 to 9) and mating their connectors to
the MDS Shelf.
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 4, 5, and 6 or 7, 8, and 9),
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 (J1C265AE-1) with a total of eight shelves (4
assemblies) per 7 foot RT Bay (maximum of 768 quad channels). Each
shelf supports 96 channels. Channel Unit circuit pack slot positions are
designated as 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.
NOTE:
Follow the MDS backplane routing diagram for each connector and use the
appropriate cables Group 4, 5, or 6 (for right duct entry) and Group 7, 8, or
9 (for left duct entry).
