RE: Clock Tolerance and WAN PHY
To quote the objectives:
"Define two families of PHYs
- A LAN PHY, operating at a data rate of 10.000 Gb/s
- A WAN PHY, operating at a data rate compatible with the payload rate of
OC-192c/SDH VC-4-64c"
That's all the objective says. By that objective, we could create a "WAN
PHY" that that is just the 10GBASE-R PHY pushing data onto the fiber at
9.58464 Gb/s, without any SONET overhead. The objective was meant to be
vague so that the task force had some flexibility.
Cheers,
Brad

Rich,
You have a very good a presenting that would seem reasonable to those who
don't have any experience in attempting to implement what you are
proposing. The objectives of P802ae include a WAN PHY. What constitutes a
WAN PHY has been explained to the group by those of us that have worked in
a WAN optical environment. You keep miss representing the requirements of
a WAN PHY by presenting a LAN implementation as a WAN. It works very well
at confusing those that are attempting to gain an understanding of what the
issues are.
Those of us that have worked in the WAN optical environment are not
confused by your comments. Those of us that have worked in the WAN optical
environment would like to have the opportunity to educate those that would
actually like to gain a understanding of what the real world requirements
are.
Thank you,
Roy Bynum
