RE: [10GBASE-T] PAR and 5 critters

The 3-PHY vendor presentation made in Portsmouth (sallaway_1_0503)
calculated 49.36 Gbit/s capacity using unscaled Cat 7/Class F cabling. This
figure was reduced to 37.71 Gbit/s with worst case limits. Overall, I
thought that this was a refreshingly realistic presentation and I
interpreted the summary statement "Capacity calculations with measured data
indicate 10 Gigabit data transmission over 100m Cat 7 may be possible"
(slide 16, bullet 3) as overly cautious engineering judgement.

So, what has changed since the May interim? Not the laws of physics!
