Re: [802.3_4PPOE] 57V

Dan -

I’d prefer:

"Type 1 and Type 2 PDs shall withstand any voltage from 0V to 57V at the PI indefinitely without permanent damage.

Type 3 and Type 4 PDs shall withstand any voltage or combination of voltages from 0V to 57V across any combination of Mode A and Mode B conductor pairs (defined in Table 33-13) indefinitely without permanent damage.

These tests shall be run with the two conductors of each tested pair tied together.”

This preserves the ambiguous text from AT for Types 1 and 2 while making Types 3 and 4 clear and stopping the across-a-pair problem.
