Foreword
This final draft ETSI Standard (ES) has been produced by ETSI Technical Committee Electromagnetic compatibility
and Radio spectrum Matters (ERM), and is now submitted for the ETSI standards Membership Approval Procedure.
The present document defines the EMC requirements of telecommunication network equipment for an increased
reliability and the resistibility requirements.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The present document defines EMC requirements for telecommunications equipment to guarantee enhanced availability
of service in specific applications. Resistibility requirements are also defined with reference to ITU-T K series
recommendations.

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;
- transmission equipment which includes multiplexers, line equipment and repeaters, Synchronous Digital
Hierarchy (SDH), Digital Cross Connect (DXC), Asynchronous Transfer Mode (ATM) and network
terminations;
- 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;
- transmission equipment which includes multiplexers, line equipment and repeaters, Synchronous Digital
Hierarchy (SDH), Digital Cross Connect (DXC), Asynchronous Transfer Mode (ATM) and network
terminations;
- 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.
