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

SPI Public Input
All,
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.
Fred
