This EMC standard specifies requirements for emissions originating from within wire-line telecommunication networks using telephone wires and the immunity of those networks, including their in-premises extensions by references to harmonised EMC product standards and other standards with EMC requirements in combination with good engineering practice, when installed and operated as intended.This standard covers the frequency range 9 kHz to 400 GHz. The assessment of a network needs to be performed only in the frequency ranges where limits are defined in the relevant product standards.The emission limits set in this standard do not apply to the wanted emissions from embedded radio links within the network.The requirements have been selected so as to ensure that electromagnetic disturbances generated by a network, or parts thereof, operating normally do not exceed a level above which radio and telecommunications equipment or other equipment cannot operate as intended. Fault conditions of the network are not taken into account.
