RE: [10GBASE-T] Proposed modification to PAR scope
In reading the
requested change it states that the PHY is to operate "on horizontal structured
copper cabling". This says that it is
to operate on all the horizontal cabling within a building or campus as per the definition of
structured (generic) cabling in ISO or TIA. I thought somewhere we had
targeted this to the data center ?
I support the
change. The current scope is too wide open with respect to the type of PHY
being defined. Almost anything, e.g. a 100 MHz PHY for coaxial cable,
would fit within "to add a copper Physical Layer (PHY) specification."
Tweaking the text to make the intended direction more clear is very
appropriate. If there is a specific point in Howard's suggestion that you feel
is too limiting, then suggest an alternative.
I do not
support this change. I think the PAR and objectives already make it
perfectly clear that we are only defining a PHY.

Howard Frazier has proposed the following
modification to the scope of the 10GBASE-T PAR to help narrow the focus
and prevent the interpretation that the Study Group is planning to make
modifications to the MAC, and to make sure the Study Group is focused on
the horizontal structured copper cabling environment:
Specify a Physical Layer
(PHY) for operation at 10 Gb/s
on horizontal structured
copper cabling, using the existing
Media Access Controller,
and with extensions to the appropriate
physical layer management
parameters, of IEEE Std 802.3.
Is there any
feedback on this proposed modification?
