A friend of mine decided to make his own patch cable, thoght he did a
good job but found he had far more 'collisions' then expected. The
cause was that while he'd wired it up correctly he';d swapped teh
colours over resulting in the pairs being re-twisted I think. Whenn
tested he got around 3o-50% collisons which appeard to reduce the
overall speed of the cable.



You mean he made a twisted pair cable into a none twisted pair cable.
It goes to show how resilient ethernet is when it still works over the
wrong cables.

Its why you need to test it properly as the actual software will still
work but it may not get the best out of the network.
