OT: Ethernet/Telephone cabling

[dave at microway.com (David Backeberg)]

You can google for the pinout of a typical ethernet cable. There are only four 
wires used, but if you tried using six of those conductors you might get some 
crosstalk. I imagine the four wires that aren't used are done intentionally 
to preserve signal quality.
