RE: Ethernet Line Tuning

Yep, that is what I was wondering too, i.e. what is considered "wired
correctly" ?

Thanks,

Chuck

Really.  I learn something new every day.   Do you have a link available
to
read what pairs are actually needed for 100 Full?  Or post the specs
here.

Tks

Slight correction: 10 and 100Mb will operate happily *HALF or *FULL on
only
two pairs. Clearly bad cable can preclude the use of 100Mb speeds but if
the
cable works at *HALF it will work for *FULL duplex. If you intend to go
to
1000Mb (1Gb) then you will need ALL FOUR pairs correctly wired and you
WILL
need cat5 or better wire.

Chris is right that basic cable testers don't test for duplex because
they
don't actually communicate with the switch or hub, they just test the
wire.
