Either standard works fine for ethernet or token ring, so long as the
connectors are paired the same on each end. IIRC, the token ring specs
call for 586A, which is probably why I saw it used, but I've also seen
token ring over 586B UTP too. If I get around to setting up token ring
here at home, I will probably just stick to 586B for everything, just to
keep things simple.
