This may be a little out there, but does anyone know what causes the
link light to show on an ethernet jack when the cable is plugged in?
Is it as simple as just attaching an led to one of the signal wires, or
is there some logic in there. Just curious.
Logic.
I have a picture of this loopback thing I made on my keyring which
will take ~1 lifetimes to upload from my cell phone. Using it you can
plug it into something and it should give it link. Works on anything
except some Sun stuff (configuration dependent) IME.

Yeah, but which circuit? The transmit, receive or maybe the unused pairs?
That got me wondering also.
Anyone know what pair triggers the light???
The transmit pair must be connected to the receive pair. This will make

It is all the used pairs. The unused are not part of the circuit. The
easy way to test this is make some patch cables. Leave out a wire. We
have probably all seen patch cables where the unused wires are not
even in the connector.
