3.4.12 ACR, Remote ACR
ACR is computed from NEXT and Attenuation results.
ACR (f) = NEXT (f) - Attenuation (f)
The accuracy is calculated from the NEXT and Attenuation accuracies.
3.4.13 PSACR, Remote PSACR
PSACR is computed from PSNEXT and Attenuation results.
PSACR (f) = PSNEXT (f) - Attenuation (f)
The accuracy is calculated from the NEXT and Attenuation accuracies.
