scope:

This EMC standard specifies limits and methods of measurement for emissions originating from within traditional telecommunication networks and the immunity of those networks, including their in-premises extensions by references to harmonised product standards in combination with good engineering practice, when installed and operated as intended. This standard covers the frequency range 9 kHz to 400 GHz. To date, it specifies limits and methods of measurement for conducted and radiated disturbances from telecommunication networks in the frequency range 150 kHz to 6 GHz. The assessment of a network needs to be performed only in the frequency ranges where limits are defined. 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 that could prevent other equipment from operating as intended. Fault conditions of the network are not taken into account.
