The third and fourth pairs would not be "so on". They'd be the pairs
on
either side of the center, since Orange+White/Orange
and
Brown+White/Brown
are not split.
Er, no, in a USOC-wired RJ45 pair 1 is pins 4+5, pair 2 is pins 3+6,
pair 3 is pins 2+7, pair 4 is pins 1+8. You're thinking of TIA 568,
where pair 1 is 4+5 (blue), pair 2 is 3+6 (green), pair 3 is 1+2
(orange) abnd pair 4 is 7+8 (brown), as I wrote above the bit you
quoted.
