4、REWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studyi
5、ng technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups
6、 which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO
7、 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions
8、 (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such w
9、ords does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position c
10、oncerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected b
11、y patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

ITU-T A.2 (11/2012) 1 Recommendation ITU-T A.2 Presentation of contributions to the ITU Telecommunication Standardization Sector (1984; 1988; 1993; 1996; 2000; 2004; 2008; 2012) 1 With regard to the presentation of contributions to the study of Questions assigne
14、d to the ITU Telecommunication Standardization Sector (ITU-T), the following general directives should be applied: a) Contributions should be concisely drafted, avoiding unnecessary details, tables or statistics that make no direct contribution to the study of a Question. They should be clearly writ
15、ten with a view to being universally understood, i.e. they should be as codified as possible, use international terminology and avoid the technical jargon peculiar to the authors country. Contributors should use the units, letter symbols and graphical symbols of the international system of units (SI
16、) as supported by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). In addition, Coordinated Universal Time (UTC) should be used to designate time. b) A contribution should not, as a rule, exceed about 2500 words (requiring no more than
17、 five printed pages to be distributed), nor should it include more than three pages of figures (making eight pages in all). It should be accompanied by an abstract that is no more than 150-200 words, and which summarizes the aim of the contribution and its technical content. Whenever possible, a sec
18、tion with the heading Rationale (or Discussion) should be used for the main text, which sets forth the essential information required for justifying the proposals or conclusions of the contribution. The contribution should end with a Proposal or, if not feasible, a Conclusion (both if required). For
19、 self-explanatory proposals, the rationale section may be omitted. These directives do not apply to draft Recommendations. c) Documents of purely theoretical interest that are not directly related to the Questions under study should not be submitted. d) Articles that have been or are to be published
20、 in the technical press should not be submitted to ITU-T, unless they relate directly to Questions under study. e) Passages of an unduly commercial nature included in a contribution may be deleted by the Director of the Telecommunication Standardization Bureau (TSB) in agreement with the chairman; t
21、he author of the contribution shall be advised of any such deletions. Detailed guidelines recommended for the preparation of contributions are provided in Appendix I. Details on the presentation of ITU-T texts can be found in the “Authors Guide for drafting ITU-T Recommendations“ (referred to as “Gu
22、ide“ in the following). 2 With regard to the submission of contributions and TDs (including liaison statements), all documents to ITU-T should, as far as possible, be sent using electronic means; if no such facilities are available to the contributor, submission of paper only copies is acceptable. E
23、lectronic submission facilities include e-mail and the ITU web-based interface. Detailed information and instructions for these methods are maintained by TSB on the ITU-T website and disseminated periodically via TSB circular. If contributions are submitted as paper documents, they shall be addresse
24、d to TSB and copied to the study group chairmen and vice-chairmen, working party chairmen and concerned rapporteur(s). 3 Contributions should be printable in A4 format, as far as possible. The first page must have the standard layout of ITU-T contributions. Drafts must be in one or more of the offic
25、ial and working languages of the Union. When existing ITU-T texts already translated have been used in some parts of a contribution, a copy of the contribution with a precise reference to the original 2 Rec. ITU-T A.2 (11/2012) sources also should be sent to TSB. If ITU-T figures are used in the con
26、tributions, the ITU-T number must not be deleted, but if the figure has been modified, the abbreviation “mod“ should be added after the number. If not required by further development of the text, use of colours in the text of contributions or other submitted documents should be avoided. 4 If a contr
27、ibution contains electronic material (software, test data, etc., referred to herein as “software“), it should be attached to the text sent to TSB. Contributors are encouraged to submit formal language descriptions as electronic attachments. Rec. ITU-T A.2 (11/2012) 3 Appendix I Detailed guidelines f
28、or the preparation of contributions relative to the study of ITU-T Questions (This appendix does not form an integral part of this Recommendation.) NOTE These guidelines will be updated by TSB as necessary. The updated version will be maintained on the ITU-T website and issued in a TSB circular. The
29、 guidelines in this appendix supplement the general directives set out in Recommendation ITU-T A.2. For ease of reference, they are organized under relevant headings in two categories: one deals with the contents of the contribution and the other with the mechanics of its presentation. I.1 Contents
30、of contribution A contribution should be clear, concise and comprehensive in itself. It should start with the Heading and the Abstract, which are independent sections. The main text of the contribution should contain two sections: Rationale (or Discussion) and Proposal (or Conclusion). Supplementary
31、 sections such as annexes, if necessary, should follow the main text. The guidelines for the structure of the main text do not apply to draft Recommendations or to submission by rapporteurs. I.1.1 Heading The heading of a contribution submitted to TSB should provide: study group Question number(s) t
32、hat the contribution is addressing; place and date of the meeting to which the contribution is directed; study group and working party to which the contribution should be submitted; source of the contribution: originating country and/or organization; title of the contribution; contact information fo
33、r the contribution originator and/or representative: name, organization, country, telephone, fax and e-mail address. A template that defines the recommended heading format is available (under “Guides, Tools, and Templates“) on the ITU-T study group and TSAG websites. I.1.2 Abstract The abstract shou
34、ld outline clearly and concisely the aim (for example, proposal for a new Recommendation) and the content (proposals and/or conclusions of the contribution). In addition, it should enable prospective readers to determine quickly whether the contribution contains information in their area of interest
35、 and, often, which working party(ies) should review the contribution. This is a very important part of the document and would normally be prepared after the other sections are written. An abstract should not exceed 150-200 words. It should be understandable by other study groups and not just the int
36、ended readers of the contribution. I.1.3 Rationale (Discussion) This section should provide discussion, reasons and justification for the proposals or conclusions. It develops the theme, describing the methods used and the observations or findings, and comments on their significance. I.1.4 Proposal
37、(Conclusion) The main text should end with a conclusion that, whenever possible, should be in the form of a concrete proposal indicating the intended disposition of the contribution. It would be useful to make the following distinction between Proposal and Conclusion, so that a standard approach to
38、their application may be adopted. The heading Proposal should be used when the section offers suggestions for acceptance (such as solutions, plans and changes the contributor expects to be implemented) and when decisions or actions are requested. The heading Conclusion should be used when it is mere
39、ly informational, such as summarizing observations and no decision about a course of action is expected. If both appear in a contribution, the proposals should follow the conclusions. 4 Rec. ITU-T A.2 (11/2012) I.1.5 Supplementary Sections Supporting or more detailed information that might interrupt
40、 the flow of ideas in the main text should be placed in the sections containing annexes, appendices, references and attachments. A solid line can be used to separate such sections from the main text. “The Guide“ describes the distinction between the uses of Annex and Appendix. I.2 Mechanics and pres
41、entation I.2.1 Clause numbering The contribution should be structured logically and, whenever clarity and flow demand, hierarchically, with discrete clauses and subclauses for presenting different levels of detail. Different clauses and subclauses in the main text should be designated with decimal n
42、umbers, adhering as much as possible to the hierarchical numbering system recommended for ITU-T texts (see “Guide“); for example, 1.1, 1.2.3. Examples for numbering the supplementary sections are A.1.1 of Annex A and VI.3.4 of Appendix VI. I.2.2 Page numbering The title page should be left unnumbere
43、d. All the following pages should be numbered consecutively from page 2, including tables, annexes, appendices or attachments. Page numbers should normally be centred at the top of the page. Each page should include the document number (if available) immediately below the page number. It is useful t
44、o show the total number of pages with the page number, e.g. 2 of 10. I.2.3 Figures and diagrams Figures and diagrams must be clear and legible when printed in A4 format. I.2.4 Formulae Mathematical formulae should only be presented for explaining texts. Details of how they are derived should be avoi
45、ded. I.2.5 Quotations Simple reference to the document number or paragraph number of an existing text or key phrase should be used instead of lengthy quotes. Material available elsewhere in ITU-T should not be reproduced or quoted at length. Excerpts or brief summaries may be included in the contrib
46、ution when it is known that the members of the ITU-T study group do not have ready access to such material. I.2.6 References Reference to other ITU-T contributions or Recommendations should be made by using the official document number, e.g. COM 14-10. If the referenced contribution belongs to a pre
47、vious study period, this fact should be noted as well. References to standards other than ITU or ISO/IEC publications or standards should conform to the requirements of Recommendation ITU-T A.5. Other publications not covered by Recommendation ITU-T A.5 may be referenced in a Bibliography. (See “Gui
48、de“ for more information on references and bibliographies.) I.2.7 Revision to existing text If a contribution proposes modifications to an existing text, e.g. draft Recommendation, the portions of the text to be modified should be clearly shown with revision marks. Adequate indications shall also be
49、 given to identify any changes proposed with regard to the previous version of the same text. Such change indications could be made, for example, by strikethrough, underlining and by vertical revision bars (|) appearing at the margin of the page.
