I'm looking up things on cat 6 cabling and I see a mention on Wikipedia about 568B being deprecated as an official wiring standard. I click over to the TIA/EIA 568 page and see the same thing. Both entries have [citation needed] tags so I'm leery of believing it (I'm leery of believing it anyway). Has anyone heard anything about this before?

en.wikipedia.org/wiki/T5 ··· minationIt even mentions this: The United States National Communication Systems Federal Telecommunications Recommendations explicitly forbid T568B, as does all US Federal guidance on new construction for the US Government.
If that's true then what is so bad about 568B? Sure 568A lines up better with lines 1/2 on a standard RJ11 jack for phone service but that's about all I can think of. Plus you STILL need 568B for a crossover cable. I've always preferred 568B personally and I've noticed many of the pre-made patch cables I have are wired as 568B.
