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-p air amphenol connector attac hes 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 c onnects the DS1 CONV to a
fiber-optic c able, enabling the DS1 CONV to connec t to an EI or SNI at a greater
distance. The cable end with one 25-pair amphenol c onnector attaches to a
lightwave transceiver using the 846885259 bracket. The end with two 25-p air
amphenol connectors attac hes to the DS1 CONV I/O Plate connector. The other
end of the fiber-optic cable connec ts to a lightwave transceiver att ached to the
I/O plate connector of the EI or SNI.
An H600-348 cable connec ts 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-cab le to the wall field. See the pinout for the 50-p in
connector at the end of the Fib er Fault Isolation Procedure in Chapter 5, ‘‘Alarms,
Errors, and Troubleshooting’’.) This cable provid es from one to four DS1
connections. One end of the H600-348 cable is plug ged into the 50-pin
amphenol pigg y-back connec tor on the 8464486xx cable c onnected to the
DS1CONV port connector. The other end of the H600-348 c able has four 15-pin
sub-miniature D-type connec tors that plug into the CSU. A pino ut of this cable
appears the end of the Fiber Fault Isolatio n Procedure in Chapter 5. H600-348
cables come in the followi ng lengths:
Group No. Length Group No. Length
