Straight-through—The colored wires are in the same sequence at both ends of the cable.
•
Cross-over—The first (far left) colored wire at one end of the cable is the third colored wire at the
other end of the cable.
•
Roll-over—The colored wires are in the opposite sequence at either end of the cable.
