Straight-through Cable
The majority of twisted-pair environments use twisted-pair cables
that are wired straight-through. This means that each pin of the
modular plug connector is wired to the same pin on the opposite
end of the cable (i.e., pin 1 is wired to pin 1). Straight-through cables
connect workstations and servers to repeaters and switches. Cables
for 100BASE-TX use two pairs (pins 1, 2, 3, and 6).
