Re: [802.3_4PPOE] Analysis of E2EP2PRUNB with Dual Signature PDs

Hi Yair,

Referring to the picture on page 7, if the ground of the loads is the same, there is current sharing between the return lines (in blue)

So even if the  loads are different, the current on the return path is balanced, and may be higher then expected on the pairset with lower class.

So, if there is a common point between the pairs in the PD the two classes must be the same.

Do you agree with that?



Best regards
