HI Rich
You also need to ask the people who still want Dc-coupling, how many
would agree to a common mode
voltage. Earlier when I proposed a common mode voltage and a method of
AC and DC coupling everyone
wanted their own common mode voltage. Without agreeing t to a common
mode we have no standard and no point to discuss it under 802.3.
