Well my first reaction was WHAT??????  Then I googled it and found this.

And it seems that Lewis is indeed correct.  Well I never knew
that.................... well if I did I would have then said something like
he did.  Guess I just never gave the 568A & B enough thought before.  You
learn something every day.  And so it goes.

Thanks Lewis!!!

And now I have re-read the OP and I think I understand what he was
questioning.  If the BOTH ends of a Patch Cord is configured as a A or a B
it does not matter it will work the same.

If a Jack is configured as A on one end it needs to be configured as A on
the other end for a Ethernet connection to work, same goes for B.  So if you
have a Patch Cord at A - A and a Jack that is B - B all works fine.  It will
not work if you interject a A - B (crossover) into the mix.

If the Patch Cord is configured each end one at A and the other at B it will
only work between two PC's.

I hope that makes sense.  Sorry I went down a misinformed path earlier.
