Colleagues,
After Study Group discussion, please find below the resolution of comments received on P802.3ca PAR/Objectives/CSD. If you have additional questions or comments, please let me know.

From Paul Nikolich:
Regarding the 802.3ca draft PAR 5.4 Purpose:
The 1st sentence uses the qualitative term 'significantly increase performance..'. It should be replaced with 'increase by 2.5 to 10 times the performance..." to be in line with the Scope.
Response: Since having a Purpose clause in the P802.3ca PAR is an error and will be deleted, this comment is overtaken by events
From James Gilb:
General question: With wireless standards, we often specify a target operating range. Is there a reason why a target distance is not specified for NG EPON? It seems that the stakeholders would have some expectation of the length of fiber over which this standard can reliably deliver the advertised data rate. This distance should be stated in the scope.
Response: 802.3 typically does not specify reach requirements in PAR Scope statements, but instead places these in the project objectives. Please see the objectives for information related to target distances and split ratios.
From David Law:
The issue with the Purpose clause is, as indicated by the question related to item 5.4 'Will the completed document (base + amendment) contain a purpose clause?:', that if the answer is yes, the text in the box will be the purpose clause for the entire (base + amendment) IEEE 802.3 standard. I suspect that there will be significant push back from the IEEE 802.3 Working Group to have a purpose statement in IEEE Std 802.3 for the first time, and to have it only be related to EPON, regardless of how successful a part of IEEE 802.3 that EPON undoubtedly is
Response: The Purpose clause will be deleted

David
My comments on the PARs are as follows:
802.3ca
-General question: With wireless standards, we often specify a target
operating range. Is there a reason why a target distance is not
specified for NG EPON? It seems that the stakeholders would have
some expectation of the length of fiber over which this standard can
reliably deliver the advertised data rate. This distance should be stated in the scope
802.3b
-General question: With wireless standards, we often specify a target
operating range. Is there a reason why a target distance is not
specified for this standard? It seems that the stakeholders would
have some expectation of the backplane distance or copper twinax
length over which this standard can reliably deliver the advertised
data rate. This distance should be stated in the scope.
CSD
Compatibility: This 5C states that "shall be compatible with 2.5 Gb/s and 5 Gb/s MAC operation being defined in IEEE P802.3bz". If so, then the PAR (5.3) should reflect that this standard depends on the completion of IEEE P802.3bz.
