EI-to-SNI or EI-to-EI intracabinet metallic
cabling
Metallic cable can be substituted for fiber-optic cable for “fiber” connections between EIs or between an
EI and an SNI in the same MCC cabinet, using the same I/O plate connectors.
!
DANGER :
The metallic cables should not be used for intercabinet connections, since doing so
would violate system ground integrity.
Table 40, Metallic cable specifications, on page 99 lists the part numbers and uses for the two (2) metallic
cable lengths.
DS1 CONV cabling
When fiber-optic cabling is not practical, Digital Service 1 (DS1) can be used to connect PNs up to
100 miles (161 km) apart. A TN574 or TN1654 DS1 Converter (DS1 CONV) circuit pack serves as the
interface between the network and an EI or SNI on the switch. DS1 cabling on a carrier consists of a Y-
cable that connects a DS1 CONV to an EI or SNI and to the network.
Table 41, DS1 CONV cable
specifications, on page 99 lists the lengths and uses for DS1 CONV cables, depending upon where the
DS1 CONV and the EI or SNI are located.
