Duane,
I respect your opinion, but care to differ. Input is valuable, but not when
we are asked to straw poll proposals we first see on the call

Marek,
Because I wasn?t on the call last Wed. I?ve refrained from commenting on the
technical aspects of this thread.
However, as an Ad Hoc Chair, I?d like to point out that very few
presentations have been distributed with any significant time for advanced
review. I personally would prefer that this was not that case but, given the
number of calls we have, I really don?t see creating a requirement for
advanced submission would help move the standard forward any more rapidly
than we?re moving already. Decisions are never made in any of the ad hoc
meetings, we can only make recommendations for the task force to consider.
It does provide a good opportunity to gather input from interested parties
and thus, move toward consensus.
So in summary I think our current ad hoc policy is serving us well.
Best Regards,
Duane

Ed, et al.,
Since it is not recorded in the minutes, but it was brought up on the call,
I feel it is important enough to bring it up again. I would really
appreciate if there were no more surprise presentations brought forward for
discussion. It is hard enough to have to examine proposals on the fly on a
small screen, written in minuscule font, but it is also wasteful in terms of
time to have to formulate opinions on complex topics like PLC, its framing
etc., on the fly. I think we would be better served being able to preview
the presentations before the meeting.
With that said, I plan to develop an alternative framing proposal for the
next call and distribute the draft presentation by next Monday. I would
encourage everybody to follow similar approach and give other participants
at least one working day to go through the materials ahead of the call.
Regards

All,
I have attached the slides from today?s call. Here is the a summary of the
call.
1) Editor for PLC
a. Most of PLC will be in the PCS and handled by Marek (digital and
framing)
b. Saif/Joe will handle the rest of it in the PMA.
2) Huawei and Broadcom presented a Downstream Command Format proposal
(at the end of the slides)
a. Efficient method to set blocks of configuration registers in the
PHY.
b. Marek has concerns about errors in the PLC and impact to
incrementing address.
c. Do we need to have FEC and CRC in PLC? Do we need to worry about
undetected errors multiplying?
d. Qualcomm wants to consider no address and a fixed register set for
PLC.
3) Baseline Proposal Review (slides 34-35)
a. One or more PLCs in the downstream is not clear.
b. 1MHz granularity for setting PLC location
c. General support for 6MHz min size of EPoC spectrum around PLC.
Question on whether it could be 24MHz?
d. PLC hunting is a vendor specific algorithm but MDIO controls needs
to be define. Bill K will make presentation.
e. 8 or 16 carriers for PLC are adjacent.
Thanks,
Ed?
