I assumed crossover cables were to go between A and B standards, but that doesn't look accurate. What are they for then?
It's not for going between 568A and B, it's just terminated that way. What is flipped is the transmit and receive pins. It's used in equipment that can't auto-mdix, if you need to connect two ports or two interfaces. Like interface on a NIC with a router, or ports on two switches/hubs.
