In my opinion there are 2 critical points in your proposal solution:
a)The voltage VPD is measured
between any positive conductor of a pairset and any negative
conductor of the corresponding pairset, then it is not possible to measure current between negative pairs using VPD definition.
b)If PD dual signature ties
positives together (problem #2, point d) and VPD is applied only to pairset
at the negative pair of mode B the current is very higher than 30uA (for example if VPD is included in classification range).
Therefore your solution doesn’t include the possibility to join positive together in the dual signature PD.
