straight cable notes

We will be mainly focussing on the wiring of CAT5 cables here because they are the most popluar cables around ! You will find info on wiring the classic CAT1 phone cables as well. It is very important you know how exactly to wire UTP cables because it's the base of a solid network and will help you avoid hours of frustration and troubleshooting if you do it right the first time :) On the other hand, if you are dealing with a poorly cabled network, then you will be able to find the problem and fix it more efficiently.
Wiring the UTP cables !
We are now going to look at how UTP cables are wired. There are 2 popular wiring schemes that most people use today: the T-568A and T-568B, that differ only in which color coded pairs are connected - pair 2 and 3 are reversed. Both work equally well, as long as you don't mix them! If you always use only one version, you're OK, but if you mix A and B in a cable run, you will get crossed pairs!
