Re: [802.3_4PPOE] Channel P2P RUNB - Ad-hoc list of attendees - UPDATE

Hi Fred,

Thanks for your inputs.

So you prefer?

a)      Single worst case number at room temperature?

b)      Single worst case number at TBD  low temperature were this low temperature represents wide market applications? (and no further text/inputs/requirements/guidelines for lower than that minimum temperature point?)

c)       Else?


I understand from your response that you prefer option (b)?

Hello Pair-to-Pair Ad Hoc,


I think adding temperature details to the IEEE .3BT specification will result in problems.  Stating values at temperature is not standard for IEEE specifications.


Not all vendors will operate in the same temperature range.  Requirements should be provided for interoperable operation.  Some of this may be arrived at by considering temperature for the broader market.  Vendors with wider operational needs will need to use cable made for the application and tested with .3BT requirements. Guidance for cable parameters should reference cable standards. The .3BT standard should provide guidance on how to use cable standard values for the .3BT standard.


ð  I do not want parameters for specific temperatures in the requirements of the .3BT specification.


I do not think this is a choice in the P2P ad hoc survey but it should be.  That is, I do not want this information in the appendix either as this will require .3BT to wait for cable standards to provide the values.  Values in the appendix are not tested.


Thanks for your consideration,


Fred Schindler
