ELFEXT (Equal Level FEXT)
• Tests from both directions using OMNI Remote and reports all 24 pair
combinations.

ACR (Attenuation to Crosstalk Ratio)
• Computed for 6 pair combinations from both ends at all frequency points
from the respective pair to pair NEXT and Attenuation measurements.
Bandwidth
• Computed for the link or channel under test, bandwidth indicates the
highest frequency for which the worst case pair to pair crosstalk (NEXT)
is at least 3dB less than the attenuation.
