Standards Conformance

Cabling Requirements

The cable, quality, distance, and connectors must comply with
the Electronic Industries Association/Telecommunications
Industries Association (EIA/TIA) 568 Commercial Building
Wiring Standard and the Technical Services Bulletin
TSB38 standards.

Twisted-Pair Cable

Twisted-pair cable consists of copper wires surrounded by
an insulator. Two wires are twisted together (the twisting
prevents interference problems) to form a pair, and the pair
forms a circuit that can transmit data. A cable is a bundle of
one or more twisted pairs surrounded by an insulator.
Unshielded twisted pair (UTP) is the most commonly used
type of twisted-pair cable. Shielded twisted pair (STP)
provides protection against crosstalk. Twisted-pair cable is
now commonly used in Ethernet, Fast Ethernet, and other
network topologies.
