They always used the center-pair for the first one.

Makes sense. For some reason, ethernet cables avoid using
the center pair.

Yeah? Well the center pins on an ethernet card (in a computer) are
shorted, for whatever THAT's worth.

Back in the dial-up days, I lost count of the times I would clear a hard
short trouble report by removing the RJ11 plug from the ethernet port in
the back of the computer and reconnect it into the nearby, internal
modem IN port.
Hmmm,
You mean there are some dumbs who can see the difference between RJ11
and RJ45?
