[10GBT] phy parameter list

I hope all of you have recovered from the visit to Disney World, from
the ethernet guitar music and from the wild nights at Pleasure Island.
While we made good progress in arriving at an agreement on the channel
models and on the link specification front, I am obliged to point out
that we will need to reach agreement on a number other critical
parameters to have a reasonably complete draft 1.0
I looked through the draft that George Eisler generated by modifying the
1000BASE-T spec and the large number of TBDs and listed some of the
important ones in an excel spreadsheet. The spreadsheet is attached and
I am sure Brad can help us put it on the website so it becomes a living
document. If there are other critical parameters that should be listed
in it, please send me email.
I think participants should start thinking of presentations for the next
802.3an meeting to make a case for specific values for the parameters
listed in the spreadsheet.
I am collecting information on how the selection was made for 1000BASE-T
and will come up with suggestions on how we can start the process of
comparing different phy proposals in case there isn't unanimity on all
the parameter values right from the start!
