RE: [EFM] What was the intent of Jackie Chan's motion made during the closing 802.3ah Plenary?
Actually, Roy, the presentation not seen made the point that the two PHYs were both needed as each did not seem to meet the market's needs and seemed, to me, to imply that both alone did not meet the 5 criteria. My email must have given the wrong impression as I meant the presentation implied this, but I do not support this idea. The belief I had/have is that the PHYs needed to stand on their own merits individually. If, individually, they could not meet the criteria, they should be voted down. The voting on Monday was to consider each PHY on its own merits and if it met the 5 criteria.
I, and a >75% majority on last Monday, agreed regarding SHDSL and voted it in as the LR PHY. As to ADSL, it had >40% count voting against it meeting the 5 criteria (as I understand the mood and reasoning behind the votes). I believe a majority, if not all, service providers at the meeting voted Yes for SHDSL and No for ADSL. Seems they gave a strong indication, just as the slide regarding Operator support was presented for SHDSL and the ADSL support slide showed no Operators...
I believe there comes a point where the Task Force has to make decisions and move on. The January meeting was one of these times. I am fully behind getting to the same point with VDSL. There should be no "topic left open for further discussions" as this only impedes progress and makes it appear we are ineffective and unable to make a decision.
I do not believe Behrooz's presentation as "finding a compromise" as you put it, but an attempt to make SHDSL appear weaker and to make ADSL appear stronger and to link both together in an attempt to get ADSL considered, as SHDSL was the favored PHY from as long ago as last May (boy, it does seem that we must take a long time against the same opposition to make progress here). As each was proposed as the PHY meeting the Long Reach Objective, then each should be considered individually, contrary to the gambit Behrooz decided on. There was no linkage before the meeting, only this attempt. If Behrooz had wanted his slides to be effective, I believe he should have included them in the batch of ADSL slides. Otherwise, his effort was a stand alone approach that did not coincide with the intent of the meeting, as established ahead of time.

John,
The reflector has sent this to me delayed by several days. But in reading
it I had to make a comment. As an observer of the process, I think that
you are correct in your observation that neither of the proposed SHDSL or
ADSL phys will by themselves meet the objectives, including the five
criteria. I think that what is happening is that the objective of a single
PHY, one or the other, is being replaced in discussion with a dual PHY,
SHDSL and ADSL. As an observer, I find that both are variants of xDSL and
have have individual specific advantages in specific implementations that
neither will have by themselves.
Since I was not at Vancouver, I can not say what the mood of the group was
toward the last of the meeting. It may be that having the notation, in the
form of a motion, in the minutes that Behrooz's presentation was not made
leaves the topic open of further discussion. Again, as an observer, I do
not think that this necessarily a "black eye" for anyone. It simply means
the topic has not been fully flushed out by all of the people involved.
This is not new material. The attempt to adopt both variants is using all
of the material that has been presented prior to the "cut off date", and
not throwing away one or the other.
Being an ex-service provider, I recognize the validity and need for both
variants, where only one or the other variant will fail in one or more
potential implementation markets. I think that it is a good thing that
Behrooz is making the attempt to find a compromise by not dismission one or
the other, but proposing that the 802.3ah TF adopt both as part of the
Draft. I think it would be easier to sell including both at Sponsor Ballot
than take the chance that it fail Sponsor Ballot because adopting only one
would fail to meet the objectives and five criteria.
Thank you,
Roy Bynum
