[802.3_4PPOE] PAR change



All, you might recall that I had the action to spurn conversation on the reflector around the PAR change – and I’ve been lax in getting that kick started. Here is the text we were looking at in the room:

Old PAR:

5.2.b. Scope of the project: The scope of this project is to augment the capabilities of the IEEE Std 802.3 standard with 4-pair power and associated power management information. The project will augment the methodology for the provision of power via balanced cabling to connected Data Terminal Equipment with 802.3 interfaces. Optional augmented power limit will be made available for certain structured cabling systems. Compatibility with existing equipment will be maintained.


New PAR:

5.2.b. Scope of the project: The scope of this project is to augment the capabilities of the IEEE Std 802.3 standard including 4-pair power and associated power management information. The project will augment the methodology for the provision of power via balanced cabling to connected Data Terminal Equipment with 802.3 interfaces. Optional augmented power limit will be made available for certain structured cabling systems. Enhancements, excluding the augmented power limits, introduced for 4-pair systems may be defined for 2-pair systems. Compatibility with existing equipment will be maintained.



The major haggling was over the sentence: Enhancements, excluding the augmented power limits, introduced for 4-pair systems may be defined for 2-pair systems. 

Let me suggest the first alternative:  Enhancements introduced for 4-pair systems, excluding the augmented power limits, may be defined for 2-pair systems. 

I’d like to hear alternatives – or a vote of confidence for my sentence.

Thanks,
