Glen,
I’d have to look at how IEEE Defines a
procedure. Do/can procedures complete instantaneously as in SDs? If yes then the MAC rate is purely determined by the RS (when it “passes control” back to the MAC.
In any case I think this is easily rectified – just state in the std that the RS synchronizes transfer’s over the MII. I’m confident we can smith a reasonable
statement and implementers can make it happen if it’s needed. It may end up being a tradeoff between buffers in the ONU vs buffers in the OLT.

Duane,
This is the text from Annex 4A that I mentioned on the call:
In clause 80:
So, I understand that if the PHY does not transfer the control back to MAC immediately after sending a bit, this will slow down or halt the transmission (as .3br does). But do you think it can pass the control
back to the MAC faster than a bit time for a given MAC data rate (10ps at 100Gb/s)?
