M/313 - Telecom Networks
EMC for telecom networks
Mandate M/313 requires European Standardisation Organizations to develop standards addressing electromagnetic compatibility (EMC) for telecommunications networks. This mandate aims to ensure that telecom networks operate without causing or experiencing electromagnetic interference, thereby maintaining network reliability and performance. The standards developed under this mandate support the interoperability and safety of telecom infrastructure across the European Union. It provides a framework for harmonized technical specifications that mitigate EMC issues in telecom network equipment and installations, facilitating regulatory compliance and fostering a stable and efficient communications environment.
Purpose
This mandate focuses on establishing electromagnetic compatibility (EMC) standards specifically for telecommunications networks. The goal is to ensure that telecom equipment and networks operate effectively without causing or suffering from electromagnetic interference, thereby supporting reliable communication services across the European Union.
Standardisation request
The European Commission requests the development of harmonised standards that address EMC requirements for telecom network equipment and infrastructure. These standards should define testing methods, emission limits, and immunity criteria tailored to the unique characteristics of telecommunications systems.
Expected deliverables
- Harmonised EMC standards covering telecom network devices and related infrastructure.
- Guidelines for compliance assessment procedures.
- Technical specifications for both emission control and immunity to electromagnetic disturbances in telecom networks.
Context
Telecommunications networks form the backbone of modern communication across the EU, supporting a wide range of services from voice calls to internet connectivity. Ensuring electromagnetic compatibility within these networks is critical to maintaining service quality and interoperability of equipment from different manufacturers. This mandate supports the EU’s broader regulatory framework aimed at harmonising technical requirements to facilitate a single market for telecom products and services.
The standardisation work covers electromagnetic compatibility (EMC) requirements for telecommunications networks, focusing on ensuring that telecom equipment and networks operate without electromagnetic interference that could affect performance and safety. This includes network infrastructure and related devices within the telecommunications sector.
General Information
This part of EN 50561 specifies limits and methods of measurement of radio disturbance characteristics for in-home communication apparatus that use the low voltage power installation as the transmission medium. This part of EN 50561 applies to equipment that uses frequencies including those above 30 MHz in order to communicate. Procedures are given for the measurement of signals generated by the equipment and limits are specified within the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limits are specified. The radiated emission requirements in this standard are not intended to be applicable to the intentional transmissions from a radio-transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions. NOTE The requirements defined in this standard effectively restrict the intended transmission frequencies to below 87,5 MHz.

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.

This part of EN 50561 specifies limits and methods of measurement of radio disturbance characteristics for PLC access network communication apparatus that use the low voltage power installation as the transmission medium. This European Standard applies to equipment that communicate over this medium in the frequency range 1,606 5 MHz to 30 MHz. Procedures are given for the measurement of signals generated by the equipment and limits are specified for the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limit is specified. PLC apparatus in the scope of this standard is intended to operate under the responsibility of the PLC access network operator. This part does not apply to PLC apparatus solely communicating to each other in the same home; such apparatus is in the scope of EN 50561-1.

Frequently Asked Questions
A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.
M/313 is a European Standardization Mandate titled "EMC for telecom networks". EMC for telecom networks There are 10 standards developed under this mandate.
Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.
