Category-5E cabling utilises a standard conductor color coding system. Each
pair of conductors consists of a white conductor and a colored conductor. Each
white conductor is usually marked with a colored stripe or band to prevent
incorrect pairing.

605 Plug / 610 Socket Color Sequence
Two different pair sequences are used for terminating pairs in a Category 5 or 5E
cabling system. Each pair consists of 2 conductors known as the Tip and Ring.
The tip (or L+) conductor is always white and the ring (L-) conductor is colored.
Each pair of conductors is assigned a pair of pins in the modular jack according
to one of the following standard sequences. The preferred pair assignment for
use in Australia is identified as T568A, although T568B is also used.
T568A (Preferred Australian System)
