A.2.4.2 DS1 Repeater Cable Connections
The DS1 repeater cable carries clocks, DS1 data, and overhead for
two directions. If the 314 cable is not used, the embedded data in
the overhead must also be cabled individually. In this case, indi-
vidual cables must be run for MCS–11, audio, RS-232, and ELMC.
Recommended connectorized cable assembly – PN 695-7836-001/005 (25 pair shielded
cable with 50 pin Amp connectors) (SCSI). See Figure A-7 for shelf connector location
and pinout.
Use repeater cables for cabling repeater shelf 1 to repeater shelf 2
(eastbound/westbound data/clock)
