That is exactly correct. You wire one end to the 568B standard and the other end to the 568A standard.....easy way to remember how a Crossover is wired. You ONLY do this to connect 2 computers together (2 Ethernet devices) without a hub, or to wired 2 hubs together if the hubs don't have a crossover port or switch, or aren't smart hubs. If you're wiring a computer to a hub or router, you use the standard 568B cable wiring.
