According to wikipedia: http://en.wikipedia.org/wiki/Gigabit_Ethernet Cat6 wiring is only a requirement of 1000BASE-TX equipment which only uses two pairs. 1000BASE-T, which is more common, does use all four pairs but can use Cat5 or higher wiring. -Dave -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
