5.3.7ACR/BANDWIDTH

Attenuation to Crosstalk Ratio (ACR) is an indication of how much larger the received signal is compared to the Near End Crosstalk (NEXT) on the same pair. ACR is calculated from the measured NEXT and Attenuation. The ACR value is computed at each measured Attenuation frequency. The worst-case ACR is reported for each pair combination.
