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 CSU (channel service unit), which connects to a
wall field (
Figure 12, DS1 CONV connections to remote PNs, on page 101). 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 section titled
Fiber link fault isolation on page 167). 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 DS1 CONV port connector. The other end of the H600-348
cable has four 15-pin sub-miniature D-type connectors that plug into the CSU (see pinout at the end of
the
Fiber link fault isolation on page 167 section). Table 42, H600-348 cable specifications, on page 100
lists the H600-348 cable specifications.
