How To Wire A Cat 6 Wall Jack.
If you are new to the Data Cabling or Structured Cabling Trade, or wanting to learn how to wire up your Home or apartment on your own, Knowing how to wire a jack properly is an important skill. Each Brand of connector will be slightly different from the next.. You will have to look really close at the part you purchase for its pattern chart and follow the T-568B pattern. In this picture you can see the color pattern this brand uses. For example, Blue solid go above the #4 and stripe goes to the right.
Now that you know the order of the cables, it is important to mention that you will need a special tool to make these connections. Most jacks will require a 110 Style "punch down" tool. Typically, these will cost you about $50 for a cheaper one and could be much more depending on the brand and features. Some of the retail store parts include a plastic tool that pushes the wires in but does not cut them. I would suggest you get a tool that cuts the wires as well.
In the Cabling industry, we almost always use T568B rather then T568A
The next question is: "can i use a T-568A cable in wiring that was done for T-568B" The answer is yes you can. As long as each cable has either A or B on both sides. It wont matter if you terminate a cable with A on both sides and plug into a building wiring which was done on B pattern. However, If you terminate a cable with A on one side and B on the other side, this is what is known as a Cross Over Cable.
Back in the day we did use these for LAN Parties. (ask your grandfather what those are) With a Cross over cable, you can connect to computers directly together, without the need for a switch, or router. The Transmit wires cross over to the Receive location on the other end of the cable, allowing for the signal
