Re: [802SEC] IEEE 802.3 comments on P802.1AS
Roger -
Not sure what happened with the PAR file - it was OK when I posted it -
however, the correct text is now available at that link.
In the 5C "full duplex Ethernet or similar links" is mentioned in the
"Broad Market Potential"; this should now be understandable in the context
of what the Scope says. There was a second reference under Economic
Feasibility" that we deleted because it was redundant.

Tony
