35、s second edition European Telecommunication Standard (ETS) has been produced by the EMC and Radio Spectrum Matters (ERM) Technical Committee of the European Telecommunications Standards Institute (ETSI). This ETS has been produced by ETSI in response to a mandate from the European Commission issued
36、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. This ETS, together with ETS 300 682, is intended to become a Harmonized Standard, the reference of which will be published in the Official Jou
37、rnal 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). Annex A provides requirements concerning test sites and general arrangements for measureme
38、nts involving the use of radiated fields. Annex B provides requirements concerning measuring support for pocket equipment. Annex C contains specifications for the adjacent channel power measuring receiver. Annex D is a graphical representation of subclause 10.4.1.3 referring to the limits for spurio
39、us radiation from loop receivers. Annex E contains technical specifications relevant to the EMC Directive. Annex F contains the ERC Decision which references the technical specifications in this ETS for inclusion in national type approval regulations. Annex G provides information concerning the on-s
40、ite paging service. Annex H contains a bibliography. This ETS also contains text concerning type approval of the equipment to which it relates. This text should be considered only as guidance and does not make this ETS mandatory in its status as a standard. However, this ETS can be referenced, wholl
41、y or in patt, for mandatory application by decisions of regulatory bodies. This ETS is based mainly on CEPT Recommendation T/R 20-05 and ESPA publications 4.2.6 and 4.2.6.a. The conditions for licensing as well as conditions for interfacing to Public Switc hed Telephone Network (PSTN) are determined
42、 by the appropriate authorities. Transposition dates Date of adoption of this ETS: 20 February 1998 I Date of latest announcement of this ETS (doa): 30 June 1998 Date of latest publication of new National Standard or endorsement of this ETC (dop/e): 31 December 1998 I Date of withdrawal of any confl

44、for on-site paging transmitters and receivers. Although this ETS covers the general operational aspects of on-site paging systems, it is restricted to the wireless (radio and loop) communications of the service. It is assumed that the radio type of system will operate in the frequency range of 25 MH
45、z to 470 MHz, and loop systems below 146 kHz. This ETS does not cover radiation below 25 MHz, except for the output of loop equipment. This ETS does not include performance characteristics that may be required by the user or requirements for interfacing equipment. Additional standards or specificati
46、ons may be required for equipment intended to interface to the Public Switched Telephone Network (PSTN). This ETS also contains instructions for the presentation of equipment for type testing purposes. The types of equipment covered by this ETC are as follows: - base station transmitters (radio and
47、loop) and transcoders, with or without an external 50 IR antenna connector; - base station receivers, with a permanent 50 SL connector; - pocket unit (receiver, transceiver or transmitter), with or without an external 50 111 antenna connector. 2 Normative references This ETS incorporates by dated or
48、 undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this ETS only when incorporated
49、in it by amendment or revision. For undated references the latest edition of the publication referred to applies. 1 Pl ETR 027: “Radio Equipment and Systems (RES); Methods of measurement for private mobile radio equipment“.
