Re: [STDS-802-3-EPOC] FW: [STDS-802-3-EPOC] any new presentations for Wednesday's PHY Link ad hoc committee call?
Thanks, Marek. Yes, there is a lot left to be defined.
As far as the values in the tables and your goose pimples go, these were the values approved in Motion 26 during the Victoria meetings. The downstream values are the entire set of allowed values. The upstream, at this point, are only agreed upon to be "recommended values". I don't know if this means that this list is a SHOULD requirement or if it means they are still up for debate.

Hi Joe,
Thank you for sharing these on the reflector.
When I see requirements like "The CLT transmitter shall support the cyclic prefix values defined in Table 1 for both 4K and 8K FFTs" and then a list of values in a table, I get goose-pimples. It is a testing nightmare, when someone will have to go through all these combinations and test them. What's even worse, is that the same seems to be required on the CNU side, and then we have to confirm what happens when both sides of the link are operational. I wonder whether we cannot try to narrow this list down to specific values that actually make most sense (2-3 values at best),
The second thing that caught my attention is that there is no explanation (right now) as to when CP is inserted, at what position within a frame (?), in what order etc. I assume such text with respective figures explaining that will be added at some point of time, correct ?
Finally, when I see values like 5.3125 expressed in us, I wonder whether it does not make more sense to express them all in ns and avoid many decimal places.
I understand that it is a beginning of a larger section, because right now "This section describes how cyclic prefixes are inserted into the output of the IDFT." does not really hold true :)
Regards
Regards
Marek

Mark,
Attached are a presentation and a text proposal that I sent to the reflector last week. Can Saif and I have some time in the Wednesday meeting to socialize these with the team?

Dear IEEE P802.3bn Task Force participants,
There are a number of PHY Link presentations underway for the upcoming meeting and we've pretty much discussed the work plan status as much as needed at this time.
If there any new presentations to socialize in the PHY Link ad hoc committee, please post on the reflector by tomorrow Tuesday, by 5PM pacific time.
Thank you on this request.
