The DS1 CONV to EI/SNI cable is a shielded metallic Y-cable held in place at the
EI/SNI port connector by a 4B retainer and at the DS1 CONV port connector by a
4C retainer. The cable end with one 25-pair amphenol connector attaches to the
I/O Plate connector for the EI or SNI. The end with two 25-pair amphenol
connectors attaches to the DS1 CONV I/O Plate connector.
The 13-inch cable 846448652 or 847245776 connects the DS1 CONV to a
fiber-optic cable, enabling the DS1 CONV to connect to an EI or SNI at a greater
distance. The cable end with one 25-pair amphenol connector attaches to a
lightwave transceiver using the 846885259 bracket. The end with two 25-pair
amphenol connectors attaches to the DS1 CONV I/O Plate connector. The other
end of the fiber-optic cable connects to a lightwave transceiver attached to the
I/O plate connector of the EI or SNI.
An H600-348 cable connects the DS1 CONV cable to a Channel Service Unit
(CSU), which connects to a wall field. (Alternatively, connection is sometimes
made directly from the Y-cable to the wall field. See the pinout for the 50-pin
connector at the end of the Fiber Fault Isolation Procedure in
Chapter 5, ‘‘Alarms,
Errors, and Troubleshooting’’.) This cable provides from one to four DS1
connections. One end of the H600-348 cable is plugged into the 50-pin
amphenol piggy-back connector on the 8464486xx cable connected to the
DS1CONV port connector. The other end of the H600-348 cable has four 15-pin
sub-miniature D-type connectors that plug into the CSU. A pinout of this cable
appears the end of the Fiber Fault Isolation Procedure in Chapter 5. H600-348
cables come in the following lengths:
Group No. Length Group No. Length
G1 25 feet (7.62 m) G5 125 feet (38.1 m)
G2 50 feet (15.24 m) G6 200 feet (60.96 m)
G3 75 feet (22.86 m) G7 400 feet (121.9 m)
G4 100 feet (30. 48 m) G8 650 feet (198 m)
