TRUNK CABLE—The coaxial cable used to distribute signals over long
distances throughout a cable system.
UNMANAGED MODULE— A repeater that behaves as a “dumb” repeater in a
department concentrator chassis (i.e., without a Master). It performs simple
repeating tasks like packet retiming and regeneration, but is not managed.
UNSHIELDED TWISTED PAIR (UTP)—A cable used in 10BASE-T wiring
that consists of at least two twisted pairs of 22 to 26 AWG wire. The pairs should
have at least 3 twists per foot and have an impedance of 100 Ω. Level 3, Level 4 and
Level 5 UTP cables fit these criteria.
