Power Sum ELFEXT (PSELEXT)

Computed for each pair by calculating a power sum total of the
pair-to-pair ELFEXT from the three other pairs.

Power Sum ACR (PSACR)

The ratio of the measured attenuation and the computed power sum
near end crosstalk (PSNEXT) at each frequency point.

Resistance

The dc loop resistance for each pair in the tested cable run.
