Telecommunication network equipment; Harmonised Standard for ElectroMagnetic Compatibility (EMC) requirements

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 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;*- 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. The levels do not, however, cover extreme cases which may*occur at any location but with a low probability of occurrence. In special cases, situations may arise where the levels of*disturbance may exceed the immunity test levels specified in the present document. In these instances, special*mitigation measures may have to be employed.*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.*NOTE 2: 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.
