EI-to-SNI or EI-to-EI Intracabinet Metallic
Cabling
Metallic cable may b e substituted for optic al cable for “fib er” connections
between EIs or between an EI and an SNI in the same MCC cab inet. The same
I/O plate connectors are used . The metallic cables should not be used for
intercabinet connec tions, since doing so violates s ystem ground integrity. The
metallic cable c omes in two lengths.
DS1 CONV Cabling
Digital services (DS1) can b e used to connect PNs that are up to 100 miles (161
km) apart when fiber op tic cabling is not p ractical. Multi-mode ( fiber-connected
PNs must be less than 25,000 feet (7620 m) and less than 22 m iles (35.4 km) for
single- mode fiber from the PPN.) A TN574 or TN1654 DS1 Converter (DS1
CONV) circuit pack serves as the inte rface between the network and an EI or SNI
on the switch. DS1 cabling on a car rier consists of a Y-cable that connects a DS1
CONV to an EI or SNI and to the network. The following cables may be used,
depending u pon where the DS1 CONV and the EI or SNI are located:
Part No. Length Intended use
H600-278,G1 13 inches (33
cm) From an EI in slot 1 of a switch node carrier to an SNI in the same half of the carrier (usually the
adjacent slot)
H600-278,G2 66 inches
(168 cm) From an EI to an SNI in the same cabinet, but in a different carrier or different half of a carrier
