Which term refers to crosstalk measured at the near end of the channel between pairs?

Near-End Crosstalk is the crosstalk measured on the victim pair at the same end of the channel where the measurement is made. It captures how much interference appears on a nearby pair right where the transmitter and receiver are located, before the signal travels to the far end. This is different from measurements taken at the far end, which is what Far-End Crosstalk captures. ELFEXT is a variant of far-end crosstalk that normalizes for transmitter level, to focus on coupling itself. Return Loss, on the other hand, measures reflections due to impedance mismatches, not coupling between pairs. Since the question specifies crosstalk measured at the near end between pairs, the correct term is Near-End Crosstalk.
