Draft Details

The present document specifies the EMC requirements for telecommunication equipment intended to be used within a 
telecommunications network, which provides telecommunications between Network Termination Points (NTPs) 
(i.e. excluding terminal equipment beyond the NTPs). Radio functionality (e.g. Bluetooth®, Wi-Fi®, GPS) incorporated in 
telecommunication network equipment is also within the scope of the present document. Examples (non-exhaustive list) of 
such equipment are: 
1) Switching equipment. Such equipment includes: 
- local telephone exchanges; 
- remote switching concentrators; 
- international switches; 
- telex switches; 
- network packet switches; 
- base station controllers, radio network controllers; 
- network servers and gateways. 
2) Non-radio transmission equipment and ancillary equipment. Such equipment includes: 
- multiplexers; 
- line equipment and repeaters, e.g. equipment for: 
 Synchronous Digital Hierarchy (SDH); 
 Plesiochronous Digital Hierarchy (PDH); 
 Asynchronous Transfer Mode (ATM); 
such as: 
 Digital Cross Connect systems; 
 network terminations; 
 transmission equipment used in the access network like xDSL. 
3) Power supply equipment. Such equipment includes: 
- central power plant; 
- end of suite power supplies; 
- uninterruptible power supplies; 
- stabilized AC power supplies; and 
- other dedicated telecommunication network power supplies 
but excludes equipment which is uniquely associated with or integrated in other equipment. 
4) Supervisory equipment. Such equipment includes: 
- network management equipment; 
- operator access maintenance equipment; 
- traffic measurement systems; 
- line test units; 
ETSI 
10 Draft ETSI EN 300 386 V.3.0.0 (2025-08)
- functional test units. 
NOTE 1: The function of supervision may either be performed by independent equipment or form part of other 
telecommunication network equipment. If the function of supervision forms part of a telecommunication 
network equipment, the performance may be evaluated simultaneously with other functions (such as 
switching and transmission) during EMC testing. 
5) Telecommunication network equipment incorporating radio equipment. 
6) Data centre equipment which is intended to be used within telecommunication network infrastructure: 
- Storage. 
- Processor. 
- Server. 
The requirements applicable to radio interfaces of Telecommunication network equipment within the scope of the 
present document (e.g. Bluetooth®, Wi-Fi®, GPS) are defined in clause 7 and annex D. 
The environmental classification locations used in the present document refer to ETSI TR 101 651 [i.22]. 
The emission requirements of the present document refer to EN 55032 [31] that have been selected to ensure an 
adequate level of protection to radio services. 
The immunity requirements of the present document have been selected to ensure an adequate level of immunity for the 
apparatus covered by the scope of the present document. 
General purpose equipment, which is used as a part of a telecommunication network, may be covered by the scope of 
other standards. Equipment which also fall within the scope of EN 50083-2 [3] may require additional testing on the 
relevant RF ports. See clause 9.2 and annex C. 
Equipment may provide different functions, i.e. switching equipment may also provide transmission functions and 
transmission equipment may provide storage capabilities, etc. All available functions of the EUT are to be tested. 
Technical requirements related to conducted emission EMC requirements below 9 kHz on the AC mains port of 
telecommunication network equipment are not included in the present document. 
NOTE 2: Such technical requirements are normally found in the relevant product family standards for AC mains 
powered equipment (e.g. EN 61000-3-2 [i.48] and EN 61000-3-3 [i.49]). 
NOTE 3: The relationship between the present document and essential requirements of annex I.1 of 
Directive 2014/30/EU [i.31] and/or article 3.1(b) of Directive 2014/53/EU [i.6] is given in annex A.
