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.
