DSX-1 Interconnections
General
Whenever the RT bay is configured for DDM-2000 FiberReach applications it
serves as a Host Digital Terminal (HDT). The DSX-1 panel provides the interface
between the electrical signals on the MDS backplane and the electrical signals of
the DDM-2000 shelf, or MSDT or FSM applications that use a T-Carrier facility. It is
possible to have a combination of metallic (MDS connections to MDF/FDI) and
fiber (MDS to HDOS) distribution applications. Refer to the local engineering job
specification for these assignments.
The connections between the DSX-1 and the MDS are factory provided cable
assemblies (ED7C723-35 Group 17) which must be connected between the
ABAM cables and the MDS Assembly dangler cables.
Figures 3-22 is the overview of the required interconnecting cables for the MDS/
DSX-1 application.
Connecting Procedures for Transmission
Cable Assembly ED7C723-35 Group 17
This procedure consists of installing the DSX-1 to MDS Interconnect cables and
mating their connectors to their respective shelf dangler cables.
Connections
Step 1: Install the interconnecting cable assemblies in the appropriate duct and
mate their connectors in accordance with the assigned MDS positions.
NOTE
:
The factory assembled cable connectors are universally
stamped P191/P192 IN, P191/P192 OUT, J101/J201, J102/
J202, J103/J203, J104/J204. For ease of installation erase or
cover that part of the label that is not relevant before mating to
its associated connector. For example some relevant labeling
would be:
a. P191 IN, P191 OUT, J101, J102, J103, J104
b. P192 IN, P192 OUT, J201, J202, J203, J204
Step 2:
Tie the cables in the duct space wherever appropriate.
