I could swear I remember running over a single pair, but it's been a few decades so I might be wrong about this! If 10bT really does always use 4 pins then I wonder what would happen if tx+/rx+ and tx-/rx- were shorted? I wouldn't be surprised if there's no page illustrating it because why would you ever want to?

If you've got a burried run of two pair wire that you're running ethernet on, but something happens and one pair goes bad, it might be nice to use the working pair, because trenching is a pain. Or maybe you have two pair, but you really want a phone line and ethernet (and ethernet+voip won't work). Etc lots of cases where rewiring is hard, but you don't have enough wires.
