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.

Regards,
Tony
