Re: [802.3_SPMD] Closing Remaining Comments - R1-28



Hi George,

Thanks a lot for your fast response  and feedback. We have informative annexes in POE IEEE802.3bt and I thought it would be good to have such annexes in .da standard too. I will work on a text and will try to send you tomorrow.

Best Regards

Arkadiy

Arkadiy – thank you for forwarding this.  However, to include an informative annex, we will need text to include. While the tables are useful, and can be posted in the project area of the website to inform future users of the standard, inclusion in the standard requires a bunch of work to make these into a proper annex.  802.3da is fairly advanced in the process now, so the inclusion of a new informative annex needs to be relatively straightforward and with minimal room for editorial error in order to avoid prolonging the standard’s progress by multiple cycles, taking the work of many people…

 

Do you have text?

Hi All,

I attached  presentation for calculation of voltage and current  of 16 segments in multidrop system. I am proposing to add information on  pages 8 and 10 to Informative annex of IEEE802.3da standard. Information on others pages is for  illustrative purposes and may or may not be added  to the annex based on presentation review and comments.

Please let me know if you have any questions.

Best Regards

Arkadiy

All – I encourage you to use the reflector to close the remaining comments.  I will start a thread on each.  This one is for R1-28.

 

Comment R1-28 requested an annex for examples of how the mixing segment power parameters would be derived, relative to Table 189-1.

During discussion, the editor had recommended rejecting because there was no content provided, and insufficient detail to understand what was intended to convey in the annex.

The commenter offered that he had text to propose.

 

The next action is for the commenter to provide this text so that others can review it.  Preferably, this could be supplied to the reflector or the the chair shortly so that people can review it prior to the meeting. (having to consider it blindly during the meeting is not desirable).  Responding with a PDF to this reflector email would help us all.
