Re: [802.3_4PPOE] SPI Public Input

Thanks, Fred.  This is helpful for us to study.  

From my perspective, I believe that the CMP-16 text is too focused on "PoE" as the example powering system.  While it may be the most ubiquitous, the PoE systems that are on the market are extremely safe (including accommodating extra precautions such as  device detection and classification prior to voltage delivery) and the cause for concern with PoE is significantly overstated.  Furthermore, singling out PoE as the one example makes it appear to the reader that this is the powering system to be concerned about when, in fact, there are other powering systems (such as direct injectors) that are much more likely to cause safety problems.

Hopefully, this is something that the 802.3bt Task Force can consider further in Bonita Springs.

All the best - Val

This is the main other SPI public input that expands the scope and coverage of Article 840 to match the new title “Premises-Powered Broadband Communications Systems”. 

The remaining PI's submitted by SPI make similar changes to the attached one. i.e. they expand sections of article 840 to include all types of communications systems rather than just optical ones.

I don't plan to send more of these as I don't believe they add to the discussion.

If anyone wants the other proposed language changes please let me know and I will try to extract them.
