10BASE-T and 100BASE-TX only require 2 pairs. There was a version of 100Mbit that required 4 pairs(100BASE-T4), but I believe it is obsolete. Anyone still using 100BASE-T4 would almost certainly be aware of that fact. http://en.wikipedia.org/wiki/Ethernet_over_twisted_pair http://en.wikipedia.org/wiki/Fast_Ethernet#100BASE-T4 Gigabit ethernet(1000BASE-T) requires 4 pairs. -- Galen Seitz gal...@seitzassoc.com _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
