Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document is part 2 of a multi-part document covering Telecommunication network equipment
ElectroMagnetic Compatibility (EMC) requirements, as identified below:
Part 1: "Product family overview, compliance criteria and test levels";
Part 2: "Product family standard".
The present EN has been produced by ETSI in response to a mandate from the European Commission issued under
Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of information in the field of
technical standards and regulations.
The present EN 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") (89/336/EEC as amended).
Technical specifications relevant to the EMC Directive are given in annex A.
National transposition dates
Date of adoption of this EN: 5 December 1997
Date of latest announcement of this EN (doa): 31 March 1998
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 30 September 1998
Date of withdrawal of any conflicting National Standard (dow): 30 September 2002

1 Scope
The present document defines the product-specific performance criteria and operating conditions for equipment intended to
be used within a telecommunications network (as defined in clause 3):
- Switching equipment. Such equipment includes:
- local telephone exchanges;
- remote switching concentrators;
- international switches;
- telex switches;
- network packet switches.
General purpose equipment which is used as a part of a switching system may be covered by the scope of other
standards. For such equipment, if those other standards fully cover all the requirements of the present document,
no further requirements are necessary. Switching equipment can also contain transmission functions, and this has
to be recognized during testing.
- 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;
such as:
- Digital Cross Connect systems;
- network terminations.
- 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.
- Supervisory equipment. Such equipment includes:
- network management equipment;
- operator access maintenance equipment;
- traffic measurement systems;
- line test units;
- functional test units.
7 EN 300 386-2 V1.1.3 (1997-12)
The function of supervision may either be performed by independent equipment or form part of other
telecommunication equipment. If the function of supervision forms part of a telecommunication equipment, the
performance may be evaluated simultaneously with other functions (such as switching and transmission) during
EMC testing.
Supervisory equipment may also be used in conjunction with radio equipment.
The environmental classification used in the present document refers to ETS 300 386-1 [1], in particular to annex B
(Classification of environmental conditions).
The requirements of the present document have been selected to ensure an adequate level of immunity for the apparatus
covered by the scope of this 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.
Equipment for cabled distribution systems for television and sound signals as defined in EN 50083-2 [24], equipment for
submarine cable systems as defined in ITU-T Recommendation G.971 [34] and optical amplifiers as defined in ITU-T
Recommendations G.661 [27] and G.662 [28] are outside the scope of the present document.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the definitions of ETS 300 386-1 [1] subclause 3.1 and the following
definitions apply:
ac secondary interface: The output port of a ac power supply.
10 EN 300 386-2 V1.1.3 (1997-12)
ac secondary voltage: The output of the ac power supply at the ac secondary interface.
NOTE 1: The ac secondary voltage may be either:
- a stabilized ac supply derived from a dc primary supply (e.g. where the power supply is an inverter); or
- derived from the ac primary supply (e.g. a stabilized power supply used where the quality of the
primary supply is not sufficient to feed telecommunication equipment.
connection: A temporary association of transmission channels or telecommunication circuits, switching or other
functional units set up to provide for the transfer of information between two or more points in a telecommunication

nominal voltage: The nominal value of voltage that designates the type of supply.
normal service: The service mode where telecommunications equipment operates within its specification.
performance criterion: The limits of acceptable behaviour of the equipment during and after the application of the
electromagnetic phenomenon.
NOTE 2: Performance criteria A apply for continuous phenomena; performance criteria B and C apply for transient
phenomena; and performance criteria R apply for resistibility phenomena.
port: A particular interface of the EUT with the external electromagnetic environment.
power supply: A power source (within the scope of the present document) to which telecommunications equipment is
intended to be connected.
primary supply: The public mains or a locally generated ac or dc supply.
resistibility: The ability of telecommunication equipment or a network to withstand the effects of certain electrical,

primary supply.
system block: A functional group of equipment depending for its operation and performance upon the secondary power
supply.

4 Installation environment
The installation environment for the Equipment Under Test (EUT) will normally be "telecommunication centre".
Locations "other than telecommunication centre" apply where the EUT is to be operated specifically not within a
telecommunication centre, e.g. within offices, customers' premises, streets, etc.
If no restrictions are specified in the product documentation for the installation environment, the product shall comply
with the requirements of both environments, implying that the more severe test level shall be used when the test is
performed. Equipment which meets the (more severe) requirements for "other than telecommunications centres" may be
operated in either location.
5 Test methods and limits
The emission, immunity and resistibility requirements in the following tables are derived from the requirements for
normal priority of service as defined in ETS 300 386-1 [1] using, for immunity, the lowest test levels. Emission,
immunity and resistibility shall all be tested.
For additional information on general requirements for test methods and limits, see clauses 6 and 7 of
ETS 300 386-1 [1]. The test levels are compiled in the following tables.
For power supply equipment, the following conducted immunity tests do not apply to the output power port (secondary
interface) of the EUT:
- voltage dips;
- short interruptions and voltage variations.

Switch S operated unscreened pair
cables longer than

Outdoor lines carrying dc power with superimposed signals shall be treated as outdoor signal lines.
For switching equipment which is intended to be installed in locations other than telecommunication centres, the requirements for immunity to surges on outdoor signal lines and to
continuous conducted disturbances on signal lines are according to the requirements for telecommunication centres. This reduction is based - amongst other things - upon the
screening effect of multi-pair cables and specific earthing/bonding techniques in use for switching equipment.

5.1.3 Telecommunication centres, ports for indoor signal lines
Only ports connected to inter-system cables are to be tested. Testing of ports for intra-system cabling (provided in all cases both ends are controlled by the same manufacturer) is
left to the discretion of the manufacturer which is responsible for the correct installation of the cables.
