Standard cable:
  1 ----- 1
  2 ----- 2
  3 ----- 3
  6 ----- 6
  (1,2) -> (1,2) should be a twisted pair, as should (3,6) -> (3,6).

Crossover cable:
  1 ----- 3
  2 ----- 6
  3 ----- 1
  6 ----- 2
  (1,2) -> (3,6) should be a twisted pair, as should (3,6) -> (1,2).


If you are using 4-pair cable (and you probably are), you can hook up
  4 ----- 4
  5 ----- 5
  7 ----- 7
  8 ----- 8
for both setups.
