PNC Cabling — Fiber Hardware
EI-to-SNI or EI-to-EI Intracabinet Metallic
Cabling
Metallic cable may be substituted for optical cable for "fiber" connections between
EIs or between an EI and an SNI in the same MCC cabinet. The same I/O plate
connectors are used. The metallic cables should not be used for intercabinet
connections, since doing so would violate system ground integrity. The metallic
cable comes in two lengths.

DS1 CONV Cabling
When fiber-optic cabling is not practical, digital Service 1 (DS1) can be used to
connect EPNs up to 100 miles (161 km) apart. Whereas, fiber-connected EPNs
must be closer than either of these types of fiber from the switch node carrier:
25,000 feet (7.62 km) for multimode
22 miles (35.4 km) for single-mode
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. The following cables may be used, depending upon where the DS1
CONV and the EI or SNI are located:
Connection Location
On same half carrier
On different half
carriers in same
cabinet
Between two adjacent
cabinets

Length Intended use
13 inches From an EI in slot 1 of a switch node carrier to an
(33 cm) SNI in the same half of the carrier (usually the
adjacent slot)
66 inches From an EI to an SNI in the same cabinet, but in a
(168 cm) different carrier or different half of a carrier
