This Recommendation deals with the emission requirements from telecommunications networks equipment at frequencies below 150 kHz; the immunity requirements for telecommunication networks equipment, in particular with analogue voice interface, to signals at frequencies below 150 kHz are also defined.

As a result of Last Call comment resolution, the title was changed from "EMC requirements for telecommunication network equipment - performance at low frequencies (below 150 kHz)" to "EMC requirements for telecommunication network equipment (9 kHz - 150 kHz)"
