Power Sum ELFEXT accounts for which of the following?

Power Sum ELFEXT focuses on the total far-end crosstalk that a single pair experiences when several other pairs in the same cable are transmitting at once. ELFEXT measures crosstalk relative to the sending pair, and in a multi-pair system the individual crosstalk contributions from each aggressor add up. The power-sum approach combines those contributions to give one overall value for the victim pair, reflecting the worst-case crosstalk in a real multi-pair environment. This is different from single-pair crosstalk, shielding effectiveness, or insertion loss, which look at different phenomena.
