What makes you think it would occur in the twisted >segment? Crosstalk is not limited to "the terminations", nor for that matter is that even where most of it should normally occur. It is quite true that most often out of specification crosstalk will be due to faults at the connectors, but that is simply because no other part of the cable is usually worked on. With an in specs cable there is more crosstalk, generally, in about the first 10-20% of the length of the cable, at each end. That obviously includes the connectors, but it is far from restricted to it. The reason is simply that the RX pair has the lowest signal and the TX pair has the highest signal that they exhibit at any point along the cable. > Learn to read instead of simpleton perusal.

I virtually always reflects more on the person making such statements than on the one it is directed at. In your case that is universally true so far in this discussion. -- Floyd L.
