Re: [EFM] What was the intent of Jackie Chow's motion made during the closi ng 802.3ah Plenary?


I have been trying very hard not to get into this debate. However with a
short note at least I would like to state my opinion. This e-mail is not
intended to be pointing to any particular person or group

Even I said earlier to a number of people that I think making a decision for
Copper PHY is a positive step, I hope the working group pays attention to
what was said and what was not said, and hopefully remedy this to an even
better solution:

I must say the selection process in this past meeting was poor and  these
are my reasons :

1. There were a number of claims and counter claims in both presentations.
Nobody spent time to clearly to examine each side's claim. There were
sufficient discrepancies that one could not escape the fact that they are
either talking about two separate things or one side is stretching the truth
2. The meeting was dragged late near 8:00 PM and everybody impatiently was
trying to leave. If there is a belief that copper is critical, then why not
give it enough time and put a systematic process into play.
3. The presentation that I was proposing, should have been considered at the
same time as the other 2 papers and not separately. It was written with the
context of both papers in mind.
4. What concerned me was that there was absolutely no question or discussion
about verifiable size of each market. I attempted to at least bring some FCC
data to the presentation on both symmetrical and asymmetrical cases, but
unfortunately there was not enough time to discuss it or present it.
5. I don't think the SHDSL business model was fully analyzed in case when
SHDSL-PHY becomes widely successful (I highly doubt SHDSL becomes a big
play, and that is why I think tRBOCS have analyzed this) then in fact they
have could have a major mess on their hand because that potentially could
harm their ADSL market. (I wonder for example how CEO of an ILEC would react
when he finds out their ADSL rate/reach and therefore market is reduced if
some IXCs or CLECS decides to mass deploy SHDSL or worst yet SHDSL+ in the
same bundle as their ADSL market to service the residential market)

Now the working group is faced to decide whether they should agree with the
decision of task force or not.

I guess if people are satisfied that in fact all the key questions in their
mind were adequately answered then they will vote one way or another
according to their point of view. For those who are not sure about how to
move with this, I think you need to ask for clarifications and get your

Best Regards
