[10GBT] Functional block diagram
Looking through the
1000BASE-T standards (802.3 clause 40), I see a figure that is quite central to
the descriptions and the subclauses. This is Figure 40-3. The blocks identified
in this figure may not reflect any actual implementation but form the basis of
organizing a lot of the pieces of the standard. The figure also identifies the
interfaces and some of the service primitives
As we start drafting
802.3an, it will be helpful to come up with the equivalent figure for 10GBASE-T.
Those of you who have active proposals on the table should look at how you can
modify this figure to reflect your proposal. Minimal modifications will make it
more likely that we can reach a consensus on the final figure. Others who went
through standardizing and building 1000BASE-T parts - feel free to suggest
changes based on your learnings.
At the minimum, the
GMII interface gets replaced with and XGMII interface. For those who do not have
access to the 1000BASE-T standard, I am attaching the figure in .rtf format that
should be readable by Microsoft Word
Translating from
Frame to Word may have messed up some text so refer to the original in 802.3
clause 40 if you have any doubts.
I also took the
first step and changed GMII to XGMII in the text labeling the interface on the
left.
