Telecommunications Standard (ETS) has been prepared by the Equipment Engineering (EE) T
15、echnical Committee of the European Telecommunications Standard Institute (ETSI), and is now submitted for the Public Enquiry phase of the ETSI standards approval procedure. The present ETS constitutes a subpart of a multi-part ETS as shown below: ETS 300 386 Equipment Engineering (EE); Public teleco

17、supply equipment Subpart 4: Supervisory equipment This ETS has been prepared in response to European Commission mandate BC-T-353 and, upon citation in the Official Journal of the European Communities, is intended to become a Harmonized Standard within the terms of the New Approach. Conformity to thi
18、s Harmonized Standard will confer presumption of compliance with the essential requirements of the EMC Directive 27. Proposed transposition dates Date of latest announcement of this ETS (doa): 3 months after ETSI publication Date of latest publication of new National Standard or endorsement of this
19、ETS (dople): 6 months after doa Date of withdrawal of any conflicting National Standard (dow): 4 years after doa Secretariat note: Certain technical comments were received too late to be taken into consideration by the Technical Committee when deciding to approve the present draft for Public Enquiry
20、. In order not to delay the progress of this ETS, these comments are given in footnotes in appropriate places in the text. These comments will be addressed during the TC review following the Public Enquiry. ETSI PRETS*300 386-2-2 Yb W 3400855 0134580 789 = Page 6 Draft prETS 300 386-2-2: September 1

22、t intended to be used within a public telecommunication network. Such equipment includes: - multiplexers; - line equipment and repeaters, e.g. equipment for: - Synchronous Digital Hierarchy (SDH); - - Asynchronous Transfer Mode (ATM); Digital Cross Connect Systems (DCC); network terminations. This E
23、TS specifies the operating conditions and the minimum compliance criteria for such equipment. The applicable EMC tests, the method of measurements and the limits are specified in ETS 300 386-1 I, from which the EMC requirements are selected taking into account the priority of service provided by the
24、 equipment under consideration. The environmental classification used in this ETS refers to ETS 300 386-1 l. The requirements of this ETS do not cover those cases where a potential source of interference which produces individually repeated transient phenomena or continuous phenomena is permanently
25、present, e.g., a radar or broadcast site in the near vicinity. In such cases it may be necessary to use special protection applied to either the source of interference or the equipment interfered with, or both. Equipment for cabled distribution systems for television and sound signals as defined in
26、EN50083-2 26 is outside the scope of this ETS. 2 Normative References This ETS incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references,
27、subsequent amendments to or revisions of any of these publications apply to this ETS only when incorporated in it by amendment or revision.
