Foreword
This Harmonized European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic
compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Directive 98/34/EC [i.23] as amended by Directive 98/48/EC [i.30].
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Council Directive on the approximation of the laws of
the Member States relating to electromagnetic compatibility ("the EMC Directive") (2004/108/EC [i.24]).

1 Scope
The present document covers the EMC requirements for non-radio equipment intended to be used within a public
telecommunications network, which provides telecommunications between Network Termination Points (NTPs)
(i.e. excluding terminal equipment beyond the NTPs). Examples of such equipment are:
• 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.
• 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.
• 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.
ETSI
8 ETSI EN 300 386 V1.6.1 (2012-09)
• Supervisory equipment. Such equipment includes:
- network management equipment;
- operator access maintenance equipment;
- traffic measurement systems;
- line test units;
- functional test units.
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.
The environmental classification locations used in the present document refers to TR 101 651 [i.22].
The 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. For such equipment, if those other standards fully cover the requirements of the present document, no
further assessment is necessary. Equipment for cabled distribution systems intended only for television and sound
signals as defined in EN 50083-2 [3] and optical amplifiers as defined in ITU-T Recommendations G.661 [i.6] and
G.662 [i.7] are outside the scope of the present document.
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.

Foreword This Harmonized European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document has been produced by ETSI in response to a mandate from the European Commission issued under Directive 98/34/EC [i.23] as amended by Directive 98/48/EC [i.30]. The present document is intended to become a Harmonized Standard, the reference of which will be published in the Official Journal of the European Communities referencing the Council Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility ("the EMC Directive") (2004/108/EC [i.24]).

ETSI ETSI EN 300 386 V1.6.1 (2012-09) 7 1 Scope The present document covers the EMC requirements for non-radio equipment intended to be used within a public telecommunications network, which provides telecommunications between Network Termination Points (NTPs) (i.e. excluding terminal equipment beyond the NTPs). Examples of such equipment are: • 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. • 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. • 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. SIST EN 300 386 V1.6.1:2012

ETSI ETSI EN 300 386 V1.6.1 (2012-09) 8 • Supervisory equipment. Such equipment includes: - network management equipment; - operator access maintenance equipment; - traffic measurement systems; - line test units; - functional test units. 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. The environmental classification locations used in the present document refers to TR 101 651 [i.22]. The 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. For such equipment, if those other standards fully cover the requirements of the present document, no further assessment is necessary. Equipment for cabled distribution systems intended only for television and sound signals as defined in EN 50083-2 [3] and optical amplifiers as defined in ITU-T Recommendations G.661 [i.6] and G.662 [i.7] are outside the scope of the present document. 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. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies.
