I gotta confess I did not look within the quote block.It was sort of buried in the quote from Ethernet:
ETHERNET QUOTE: The already isolated transformer output is not used for any other purpose than obtaining 230V 50Hz pulses, it has no grounded side.
(My Reply in blue in the quote): In that case you ground one side of the output and use the suggested comparator, one-shot circuit.
So guess my reply wasn't that obvious.
