RE: [10GBASE-T] Proposed modification to PAR scope

[pat_thaler@agilent.com]

Bruce,

 

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.

 

Regards,

Pat

I do not support this change. I think the PAR and objectives already make it perfectly clear that we are only defining a PHY.

Greetings,

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?

Thanks,
