(Main)Additional ElectroMagnetic Compatibility (EMC) requirements and resistibility requirements for telecommunications equipment for enhanced availability of service in specific applications
Additional ElectroMagnetic Compatibility (EMC) requirements and resistibility requirements for telecommunications equipment for enhanced availability of service in specific applications
The present document covers the emission, immunity and resistibility requirements for telecommunications equipment
where higher performance is required by operators to guarantee enhanced availability of service in specific applications.
The environments considered in the present document are defined in ETSI TR 101 651 [i.5] and are:
• telecommunication centres (classes 1 and 2 of ETSI TR 101 651 [i.5]);
• locations other than telecommunication centres (classes 3 and 4 of ETSI TR 101 651 [i.5]).
Data centres and similar facilities are also considered telecommunication centres, where they are within a dedicated
room with servers, storage devices and associated telecommunication equipment.
Considering that all kinds of equipment are not equally important, two equipment categories and associated EMC
requirements are introduced and are designated as:
• level 1 (see tables in clauses 9.1.1.1 to 9.1.1.5 and 9.2.1.1 to 9.2.1.5);
• level 2 (see tables in clauses 9.1.2.1 to 9.1.2.5 and 9.2.2.1 to 9.2.2.5);
the latter containing the more demanding requirements.
The appropriate level should be chosen by the operator considering the consequences of failure of the equipment which
may lead to impaired function, loss of service, failure to meet contractual obligations or bad publicity and loss of
reputation.
The present document is applicable to all equipment types, examples of which are listed below:
• switching equipment which includes trunk and local telephone exchanges, remote switching concentrators,
international switches, telex switches and network packet switches, base station controllers, radio network
controllers, network servers and gateways;
• non-radio transmission equipment which includes multiplexers, line equipment and repeaters, Synchronous
Digital Hierarchy (SDH), Digital Cross Connect (DXC), Asynchronous Transfer Mode (ATM) and network
terminations, transmission equipment used in the access network like xDSL;
• power supply equipment which includes central power plant, end of suite power supplies, power management
systems and other dedicated telecommunications network power supplies;
• supervisory equipment and dedicated Operation And Maintenance (OAM) equipment;
• tariff and billing equipment;
• data centre equipment which includes: Storage, Processor, Server intended to be used within
telecommunication network infrastructure.
Dodatne zahteve za elektromagnetno združljivost (EMC) in odpornost telekomunikacijske opreme za povečano razpoložljivost storitve v posebnih oblikah uporabe
Ta dokument obravnava zahteve glede sevanja in odpornosti za telekomunikacijsko opremo, kadar se zahteva večja učinkovitost, da lahko operaterji zagotovijo povečano razpoložljivost storitve v posebnih oblikah uporabe. Okolja, zajeta v tem dokumentu, so opredeljena v standardu ETSI TR 101 651 [i.5] in vključujejo: • telekomunikacijske centre (razredi 1 in 2 standarda ETSI TR 101 651 [i.5]); • lokacije, ki niso telekomunikacijski centri (razredi 3 in 4 standarda ETSI TR 101 651 [i.5]). Podatkovni centri in podobni objekti se prav tako smatrajo kot telekomunikacijski centri, pri čemer se nahajajo v namenskem prostoru skupaj s strežniki, napravami za shranjevanje in povezano telekomunikacijsko opremo. Upoštevajoč dejstvo, da vse vrste opreme niso enako pomembne, so dve kategoriji opreme in povezane zahteve za elektromagnetno združljivost predstavljene z oznako: • raven 1 (glej preglednice v točkah 9.1.1.1 do 9.1.1.5 in 9.2.1.1 do 9.2.1.5); • raven 2 (glej preglednice v točkah 9.1.2.1 do 9.1.2.5 in 9.2.2.1 do 9.2.2.5); pri čemer slednja vsebuje kompleksnejše zahteve. Ustrezno raven naj izbere operater ob upoštevanju posledic odpovedi opreme, ki lahko povzročijo zmanjšano delovanje, izgubo storitve, neizpolnjevanje pogodbenih obveznosti ali slabo reklamo in izgubo ugleda. Ta dokument se uporablja za vse vrste opreme, navedene v nadaljevanju: • stikalna oprema, ki vključuje medkrajevne in krajevne telefonske centrale, daljinske stikalne koncentratorje, mednarodna stikala, teleks stikala in omrežna paketna stikala, krmilnike baznih postaj, krmilnike radijskih omrežij, omrežne strežnike in prehode; • oprema za prenos, ki vključuje multiplekserje, linijsko opremo in ponavljalnike, sinhrono digitalno hierarhijo (SDH), digitalno prevezovanje (DXC), asinhroni prenosni način (ATM) in omrežne zaključke, opremo za prenos, ki se uporablja v dostopovnem omrežju, kot je xDSL; • napajalna oprema, ki vključuje centralno elektrarno, električno napajanje na koncu niza, sisteme za upravljanje porabe in druge namenske telekomunikacijske omrežne napajalnike; • nadzorna oprema ter namenska oprema za delovanje in vzdrževanje (OAM); • oprema za določanje tarif in zaračunavanje; • oprema za podatkovne centre, ki vključuje: prostor za shranjevanje, procesor in strežnik za uporabo znotraj infrastrukture telekomunikacijskega omrežja.

1 Scope
The present document covers the emission, immunity and resistibility requirements for telecommunications equipment
where higher performance is required by operators to guarantee enhanced availability of service in specific applications.
The environments considered in the present document are defined in ETSI TR 101 651 [i.5] and are:
• telecommunication centres (classes 1 and 2 of ETSI TR 101 651 [i.5]);
• locations other than telecommunication centres (classes 3 and 4 of ETSI TR 101 651 [i.5]).
Data centres and similar facilities are also considered telecommunication centres, where they are within a dedicated
room with servers, storage devices and associated telecommunication equipment.
Considering that all kinds of equipment are not equally important, two equipment categories and associated EMC
requirements are introduced and are designated as:
• level 1 (see tables in clauses 9.1.1.1 to 9.1.1.5 and 9.2.1.1 to 9.2.1.5);
• level 2 (see tables in clauses 9.1.2.1 to 9.1.2.5 and 9.2.2.1 to 9.2.2.5);
the latter containing the more demanding requirements.
The appropriate level should be chosen by the operator considering the consequences of failure of the equipment which
may lead to impaired function, loss of service, failure to meet contractual obligations or bad publicity and loss of
reputation.
The present document is applicable to all equipment types, examples of which are listed below:
• switching equipment which includes trunk and local telephone exchanges, remote switching concentrators,
international switches, telex switches and network packet switches, base station controllers, radio network
controllers, network servers and gateways;
• non-radio transmission equipment which includes multiplexers, line equipment and repeaters, Synchronous
Digital Hierarchy (SDH), Digital Cross Connect (DXC), Asynchronous Transfer Mode (ATM) and network
terminations, transmission equipment used in the access network like xDSL;
• power supply equipment which includes central power plant, end of suite power supplies, power management
systems and other dedicated telecommunications network power supplies;
• supervisory equipment and dedicated Operation And Maintenance (OAM) equipment;
• tariff and billing equipment;
• data centre equipment which includes: Storage, Processor, Server intended to be used within
telecommunication network infrastructure.

1 Scope
The present document covers the emission, immunity and resistibility requirements for telecommunications equipment
where higher performance is required by operators to guarantee enhanced availability of service in specific applications.
The environments considered in the present document are defined in ETSI TR 101 651 [i.5] and are:
• telecommunication centres (classes 1 and 2 of ETSI TR 101 651 [i.5]);
• locations other than telecommunication centres (classes 3 and 4 of ETSI TR 101 651 [i.5]).
Data centres and similar facilities are also considered telecommunication centres, where they are within a dedicated
room with servers, storage devices and associated telecommunication equipment.
Considering that all kinds of equipment are not equally important, two equipment categories and associated EMC
requirements are introduced and are designated as:
• level 1 (see tables in clauses 9.1.1.1 to 9.1.1.5 and 9.2.1.1 to 9.2.1.5);
• level 2 (see tables in clauses 9.1.2.1 to 9.1.2.5 and 9.2.2.1 to 9.2.2.5);
the latter containing the more demanding requirements.
The appropriate level should be chosen by the operator considering the consequences of failure of the equipment which
may lead to impaired function, loss of service, failure to meet contractual obligations or bad publicity and loss of
reputation.
The present document is applicable to all equipment types, examples of which are listed below:
• switching equipment which includes trunk and local telephone exchanges, remote switching concentrators,
international switches, telex switches and network packet switches, base station controllers, radio network
controllers, network servers and gateways;
• non-radio transmission equipment which includes multiplexers, line equipment and repeaters, Synchronous
Digital Hierarchy (SDH), Digital Cross Connect (DXC), Asynchronous Transfer Mode (ATM) and network
terminations, transmission equipment used in the access network like xDSL;
• power supply equipment which includes central power plant, end of suite power supplies, power management
systems and other dedicated telecommunications network power supplies;
• supervisory equipment and dedicated Operation And Maintenance (OAM) equipment;
• tariff and billing equipment;
• data centre equipment which includes: Storage, Processor, Server intended to be used within
telecommunication network infrastructure.
