21、ofile FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardizat

22、ion in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. I

23、nternational, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2)

24、 The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of rec

25、ommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC Intern

26、ational Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its appr

27、oval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this technical specification may be the subject of patent rights. The IEC shall not be held responsible for identify

28、ing any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an Inte

29、rnational Standard, despite repeated efforts, or The subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. IEC 61334-5-4, which is a technical specification, has been prepared by IEC

30、 technical committee 57: Power system control and associated communications. The text of this technical specification is based on the following documents: Enquiry draft Report on voting 57/479/CDV 57/517/RVC Full information on the voting for the approval of this technical specification can be found

31、 in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. A bilingual version of this publication may be issued at a later date. 1002:4543316STCEIDD 2002lirpA52ISB 4 DDIECTS6133454:2001 BSI25April2002 4The committee ha

32、s decided that the contents of this publication will remain unchanged until 2004. At this date, the publication will be transformed into an International Standard; reconfirmed; withdrawn; replaced by a revised edition, or amended. 1002:4543316STCEIDD 2002lirpA52ISB 5 DDIECTS6133454:2001 BSI25April20

33、02 5DISTRIBUTION AUTOMATION USING DISTRIBUTION LINE CARRIER SYSTEMS Part 5-4: Lower layer profiles Multi-carrier modulation (MCM) profile 1 Scope and object This technical specification describes the requirements of the multicarrier modulation (MCM) approach which incorporates the services provided

34、by the physical layer entity and the MAC sublayer with the purpose of building up a set of standards for effective communication on MV and LV network for distribution line carrier (DLC) systems, in the context of IEC 61334-1-1. Different technical approaches in developing communication systems for D

35、LC communication are in progress. As a consequence, at present, different lower layer profiles are feasible with acceptable results in terms of performance and cost-effectiveness. In many cases, the differences amongst solutions are minor and it is possible to find a common root. 2 Normative referen

36、ces The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 61334. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part

37、of IEC 61334 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of IEC and ISO maintain registers of currently valid Internati

The master station may delegate its initiatorship for a limited time to one of the slave stations registered in its domain NOTE Being an initiator is a dynamic property

44、ly using routing repeaters for multi-hop transmission NOTE Non-initiator PDUs are only sent in reaction to initiator PDUs. 3.1.10 routing repetition re-sending a PDU with a modified address field because the destination station cannot communicate directly with the source station. The routing repetit

45、ion procedure does not involve a network layer but is located in the MAC sublayer instead. A synonymous for routing repetitions is forwarding in the mobile communications context 3.1.11 slave station station that works as a communication slave within a domain. It normally operates as non- initiator,

46、 but may be switched to operate as initiator NOTE Being a slave station is a static property of a station. 3.2 Abbreviations DLC Distribution line carrier DMT Discret multitone HV High voltage LLC Logical link control 1002:4543316STCEIDD 2002lirpA52ISB 7 DDIECTS6133454:2001 BSI25April2002 7LMI Layer
