3.11 DS3 REPEATER (J401 ON ONE SHELF TO J401 ON SECOND SHELF)
The DS3 repeater cable carries clocks, data, and overhead for two direc-
tions. It does not carry DS3 or wayside DS1 traffic. DS3 and wayside DS1
cables must be run separately. If the 401 cable is not used, the embedded
data in the overhead must be cabled individually. In this case, individual
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 3 - 10 for shelf connector location and
pinout. Refer to CD for mating cable wiring and color code.
Use repeater cables for cabling repeater shelf 1 to repeater shelf 2 (east-
bound/westbound data/clock).
