His initial statements did not specify any category, and the discussion previous had been about CAT 5. When challenged he specified CAT5e and later cables. The point is *still* the same: the interface hardware cannot determine what the twist rate is, does not test which pairs are used for which data, and will work perfectly well regardless of which cable pair is assigned to which data. And that is by design, not accident. >CATegory 6 cabling is for higher network speeds - like 1 GB/s - >(so called 1000BASE-T).

Regardless, the target speeds for each category level has not been under contention, and anyone can use Google to get more information if desired. -- Floyd L.
