d. Crosstalk test

As shown the figure below: it shows 3, 6 and 4, 5 with crosstalk. The line

pair with crosstalk will flash to indicate failure. In the line pair with crosstalk,

end-to-end connection is correct. However the connected lines are from

different line pairs. Line pair crosstalk will cause an over large crosstalk,

otherwise network speed will be slow.
