Part 1-10 of EN 50289 details the test methods to determine the crosstalk cables used in analogue and digital communication systems. Crosstalk effects are near end crosstalk (NEXT), far end crosstalk (FEXT), equal level far end crosstalk(ELFEXT), attenuation to crosstalk ratio (ACR) and power sum of crosstalk (PS). It is to be read in conjunction with Part 1-1 of EN 50289, which contains essential provisions for its application.
