There are two specifications for RJ-45 pinout: T-568A and T-568B. This is true for normal cables and crossover cables. However, the wiring of crossover cables will be different than the wiring for normal cables (also known as straight through cables) regardless of which specification you use.

If you 're doing a single crossover cable for your personal use, the specification isn 't going to matter. As long as you put the wires in the right places in each connector, which color goes where is a non issue. However, for the purposes of this article I will need to follow one of the specifications.

Do I have a keyboard?" Another call came from a woman in Kansas; she was having trouble with her computer not wanting to turn on. I kept hearing this 'wild ' screaming in the background like cats being tortured. I asked her, "What is that noise?" She said, "It 's cat races! It 's driving me crazy! They strap these cats into these remote controlled motor cars and race around the mall with them. I 'm going to bring a bee bee gun in and start shooting the friggin ' things!" I thought, "Okay!
