Re: Closest I've had to that ....
Hopefully for most of you this will be a 'suck eggs' type of comment.
(Unshielded) Twisted Pair cabling works by twisting pairs of cables together so that between the two wires electromagnetic interference cancels out over each half twist. Each twist you take out of a pair of wires gives a place for electromagnetic interference to be induced in your data stream. My experience of UTP CAT 5 was that even taking an inch or two of twist out of a pair was enough to degrade the signal so that the port on the end was 'dead'.
The culprit had exposed and then untwisted about 3 inches either side of the chocblock. That particular cable was deader than corduroy!
