Summary

This Recommendation deals with planning telecommunication installations.

It gives information about:

�           the appearance of noise voltage or reduced signal-to-noise ratio (SNR) in line transmission systems;

�           parameters influencing the magnitude of the induced radio frequency voltage;

�           a method to estimate the induced longitudinal radio frequency voltage;

�           the relation between the longitudinal and transverse voltage;

�           an estimation of the accuracy of the calculation method;

�           suitable protection methods to reduce the radio frequency interference.
