Multicarrier cabinets
For information on the MCC1 (multicarrier) cabinet and the carriers in them, refer to Hardware Guide for

PNC cabling
The term "fiber" is used to refer to all the hardware needed for the three basic types of connections used
to form multi-PN systems:
• EI-to-EI or EI-to-SNI intercabinet hardware
• EI-to-SNI or EI-to-EI intracabinet hardware
• EI-DS1CONV or SNI-DS1CONV hardware
The term "fiber administration" specifies the
• Endpoints that are connected.
• Optional DS1 CONV locations.
• Parameters for DS1 facility line encoding and equalization.
The connection types discussed in this section are
•

EI-to-EI or EI-to-SNI intercabinet fiber-optic cables

• EI-to-SNI or EI-to-EI intracabinet metallic cabling
• DS1 CONV cabling
EI-to-EI or EI-to-SNI intercabinet fiber-optic
cables
EI-to-EI or EI-to-SNI intercabinet connections are implemented by installing a lightwave transceiver on
the I/O connector plate for each of the administered fiber endpoints. Each lightwave transceiver has a
receive and a transmit connector for either a 62.5-micron or 50-micron fiber connection. Standard fibers
