Re: [802.3_4PPOE] Update - 4P-PoE End to End System Imbalance (Channel Pair To Pair Resistance Imbalance) Ad-Hoc Chair. - With the attachment now

Hi all,

The worst case numbers on page 7 list for the transformer winding resistance a range of 120mOhm to 130mOhm.
Considering Fast Ethernet devices or switches that do not implement transformers on the spare pairs the range should be 0 Ohm to 130mOhm.

Kind regards,
