Which test parameter quantifies near-end crosstalk between pairs at the near end?

Explanation:
Near-end crosstalk, NEXT, measures how much energy from one pair leaks into another at the near end of the link. In testing, you drive an aggressor pair and observe the induced signal on a victim pair at the near end, expressing the leakage as a decibel ratio. Higher NEXT values (more dB) indicate less coupling and better isolation between pairs, while lower values mean more crosstalk. This parameter specifically targets interference at the near end, whereas other measures like PSNEXT sum the NEXT contributions from all other pairs to a victim pair to show total near-end interference.
