Thanks for the site reference. There's also a good primer over on the
Allied Telesyn site (http://www.allied-telesyn.com), don't recall the
exact URL at the moment.
And one thing I'd like to say to all of the folks who said "the order
doesn't matter as long as you use the same order on both ends" -- it very
definitely *DOES* matter, especially on long runs. The pair that carries a
signal should be a twisted pair (e.g. green/white-green). This is a pain
in the rear with all that donated BellSouth cable which doesn't mark the
white part of the pair, but I've had a long run of that cable fail to work
when just hooking up the solids in the same order on both ends. Apparently
cross-talk can be a killer without that twist canceling it out :-(. I
usually end up taking a permenant-ink magic marker and coding the white
parts of pairs when I strip the ends (e.g. I untwisted this white wire
from around the green, so I put a green permenant-ink stripe on it).
