ITU-T K.24 PDF

This Recommendation considers measurement methods for radio-frequency induced noise at any telecommunication pair. Locations for measurement are both the cable entry into a building and the interface point of a terminal equipment.

The frequency range to be considered is 10 kHz to 30MHz.

Note – Above 30 MHz, the technical problems of making measurements have not been solved and are therefore still under study.

Purpose of this Recommendation

This Recommendation is intended to standardize the method for measuring radio-frequency induced noise that may cause degradation of equipment performance and transmission quality. Standardization of the method for measuring induced noise makes possible the international standardization of the quality of the telecommunication system.
