Abstract

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.
• 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.23]. 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 shall be tested.

SIST EN 300 386 V1.5.1:2010 is the Slovenian adoption of ETSI EN 300 386, a harmonized European EMC standard for non-radio telecommunication network equipment used in public telecommunications networks. It specifies immunity and emission requirements for equipment between Network Termination Points (NTPs), and it is meant for manufacturers, test laboratories, network operators, quality teams and buyers who need to check EMC performance.

What does SIST EN 300 386 V1.5.1:2010 specify?

SIST EN 300 386 V1.5.1:2010 covers electromagnetic compatibility (EMC) requirements for telecommunication network equipment that is not radio equipment and is intended for use in a public telecommunications network between NTPs. The scope includes switching, non-radio transmission and ancillary equipment, power supply equipment and supervisory equipment.

The scope excludes terminal equipment beyond the NTPs, cabled distribution systems intended only for television and sound signals, and optical amplifiers. Clause 1 also notes that if another standard fully covers the same equipment, no further assessment is needed. Clause 4 organizes the document by installation environment, and clauses 5 to 14 set the test methods, limits and product-specific conditions.

AnnexWhat it covers
Annex ASurge test method for signal line ports remaining within the building
Annex BEvaluation of test results and test report content
Annex CGuidance for RF ports of multimedia network equipment
Annex DEN title in the official languages
Annex EBibliography

What are the key requirements of SIST EN 300 386 V1.5.1:2010?

Common EMC approach

Clause 4 splits the installation environment into telecommunication centres and locations other than telecommunication centres. If the product documentation does not restrict the installation environment, the equipment has to meet the requirements for all environments, using the more severe test level. In practice, this means a manufacturer should decide early where the equipment will be installed, because that choice affects the EMC test plan.

Clauses 5 to 7 define the basic immunity and emission framework. Immunity testing uses standard methods for electrostatic discharge, electrical fast transients, surge, conducted RF disturbances, radiated fields and power supply disturbances. Emission testing covers conducted and radiated emissions, harmonics and voltage fluctuations, so the same product can be assessed for both disturbance immunity and disturbance generation.

Test configuration and reporting

Clauses 8 to 10 require the equipment under test (EUT) to be configured as close as possible to normal use, with correct terminations, typical cabling and documented grounding. The report has to record the configuration, the selected ports and any justified omission of a test. In practice, this makes the test repeatable and shows why a result is representative.

Clause 10 sets the performance criteria. Criterion A expects the equipment to keep operating as intended during exposure, criterion B allows temporary degradation during the test but not afterwards, and criterion C allows temporary loss of function if the function self-recovers or can be restored. These criteria are the basis for judging whether a product passes an immunity test.

Equipment-specific clauses

Clauses 11 to 14 add product-specific rules for switching equipment, transmission equipment, Digital Subscriber Line (DSL) access systems, power supply equipment and supervisory equipment. For switching equipment, the standard distinguishes digital and analogue ports and sets different checks for connection control, frame alignment, synchronization and noise on analogue interfaces. For transmission equipment, the document uses representative traffic or bit sequences and checks bit errors, synchronization and interface function after exposure.

For DSL access systems, the equipment is tested at nominal transmission rate and in the operating modes it supports, with the line attenuation set to a minimum acceptable noise margin. For power supply equipment, the standard focuses on secondary AC and DC interfaces, alarm behaviour and voltage quality during and after disturbance. For supervisory equipment, the tests check that supervision links remain usable and that false alarms or incorrect indications do not appear.

What terms does SIST EN 300 386 V1.5.1:2010 define?

  • Equipment Under Test (EUT) - the equipment being subjected to EMC testing.
  • Network Termination Points (NTPs) - the boundary points of the public telecommunications network covered by this standard.
  • enclosure port - the physical boundary of the EUT where electromagnetic fields may enter or leave.
  • telecommunication network ports - ports used for voice, data and signalling connections to telecommunications or network systems.
  • performance criterion - the acceptable behavior of the equipment during and after exposure to an electromagnetic phenomenon.
  • AC secondary interface - the output port of an AC power supply.
  • DC secondary interface - the output port of a DC power supply.
  • Radio Frequencies (RF) - the frequency range above 150 kHz.

Who uses SIST EN 300 386 V1.5.1:2010?

SIST EN 300 386 V1.5.1:2010 is used by manufacturers of switching, transmission, power supply, supervisory and DSL equipment, because they need to design products that pass EMC tests for telecom-network use. Test laboratories use it to set up immunity and emission tests and to write reports. Network operators, integrators and buyers use it to check whether equipment is suitable for telecommunication centres or other installed locations and whether all available functions have been tested.

What changed in SIST EN 300 386 V1.5.1:2010 from the previous edition?

SIST EN 300 386 V1.5.1:2010 is the October 2010 publication of the EN 300 386 series. The history lists earlier editions and publications, including ETS 300 386-1, EN 300 386-2, and later EN 300 386 versions V1.3.1, V1.3.2, V1.3.3 and V1.4.1.

Which standards are used with SIST EN 300 386 V1.5.1:2010?

Clause 2 names the standards that support the test methods and product-specific assessments:

  • EN 61000-4-2, -4-3, -4-4, -4-5, -4-6, -4-11 - the basic EMC immunity test methods used throughout the document.
  • EN 55022 - the emission methods and limits for conducted and radiated emissions.
  • EN 55016-1-2 - the artificial network and measurement arrangements for conducted disturbance testing.
  • EN 61000-3-2, EN 61000-3-3, EN 61000-3-11, EN 61000-3-12 - harmonics and voltage fluctuation limits for AC supplies.
  • ETS 300 132-1 and EN 300 132-2 - power supply interface conditions for AC and DC equipment.
  • TR 101 651 - the environmental classification used to choose installation locations.
  • EN 300 127 - radiated emission testing for physically large telecommunication systems.
  • EN 50083-2 - extra EMC guidance for RF ports in multimedia network equipment.
  • ITU-T G.996.1, G.992.1, G.992.3, G.992.5 and TS 101 135, TS 101 524-1, TS 101 270-1 - DSL test procedures and functional requirements.

What does the SIST EN 300 386 V1.5.1:2010 document contain?

The document contains a full EMC test framework, including general installation and operating conditions, immunity and emission methods, test levels and limits, and product-specific performance criteria. It also includes figures for switching equipment, transmission equipment, DSL access systems and power supply equipment, so laboratories can build a representative test setup.

Foreword
This Harmonized European Standard (Telecommunications series) 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 Council Directive 98/34/EC [i.24] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulations.
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") (89/336/EEC [i.22] as amended and
2004/108/EC [i.25]).

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 V1.5.1 (2010-10)
• 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.23].
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 shall be tested.

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 Final draft ETSI EN 300 386 V1.5.1 (2010-05)
• 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.23].
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 shall be tested.

Foreword This Harmonized European Standard (Telecommunications series) 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 Council Directive 98/34/EC [i.24] (as amended) laying down a procedure for the provision of information in the field of technical standards and regulations. 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") (89/336/EEC [i.22] as amended and 2004/108/EC [i.25]).

ETSI ETSI EN 300 386 V1.5.1 (2010-10) 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 V1.5.1:2010

ETSI ETSI EN 300 386 V1.5.1 (2010-10) 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.23]. 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 shall 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.
