Hi Folks,
I'm making some progress in setting up a home ethernet via UTP lines. I've come to realize that there are two wiring specifications 568A and 568B that I could use in choosing hardware, wiring jacks, etc.
My understanding is that 568B (AT&T) is the original specification but
"it is recommended" that new installations use 568A.
I'm leaning towards 568B just because it's been around longer and seems
to be in common use.
Can anyone provide me with a solid reason for which specification I should choose in setting up my home/office ethernetwork?
(If this is an FAQ somewhere, please point me in the appropriate direction).
Thanks for your time.

As long as you use the same scheme at both end of a wire, it doesn't
matter which scheme you use. As I've read many time, the electrons don't
know the color of the insulation.
568B is more common in older installations in the USA. 568A is more
common in Europe and is preferred by the official EIA/TIA 568-A wiring
spec.
I'd go with 568A because the spec recommends it. It will probably come to dominate and they may one day REQUIRE 568A. Then you're ahead of the
game.

Thank you for this! Until I read your reply - the issue didn't come to mind - that the other end must be the same - you can't have B on one end and A on the other. Thank you!
