    ( You can said that it means nothing but... (; )

    I second that.  I always crimp (or check) for it.

    Also watch for Cat 6 cabling ... 23 gauge is hell to crimp.  24 is 
livable but takes twice as much time to do than Cat 5e.
    (You have to cut that little plastic guide and the pairs are a bit 
more twisted)

    I just did a 72 pairs (BIXed + crimped) in Cat 6...  And I'm still 
wondering if its that advantagious.

Also:
    Anybody fix a cabling issue by using Cat 6 over Cat 5e?

    Let us know.

is! )
