5、, http:/handle.itu.int/11.1002/1000/ 11830-en. ii Rec. ITU-T A.5 (02/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardizatio
6、n Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying 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
7、 every four years, establishes the topics for study by the ITU-T study groups 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 pu
8、rview, the necessary standards are prepared on a collaborative basis with ISO 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 vo
9、luntary. However, the Recommendation may contain certain mandatory provisions (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
10、 the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may invol
11、ve the use of a claimed Intellectual Property Right. ITU takes no position concerning 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 Recom
12、mendation, ITU had not received notice of intellectual property, protected by 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

16、cedures for normatively referencing the documents of other organizations in ITU-T Recommendations. Annex B provides the criteria to qualify a referenced organization. Clauses 6 and 7 describe the procedures in detail. Annex A provides the format for documenting a study group or working party decisio
17、n with respect to making the reference. Specific information regarding qualified organizations can be found on the ITU-T website. NOTE These generic procedures do not apply to references to standards produced by ISO and IEC. The long-standing ability to make such references continues unchanged. The
18、case of ITU-T accepting texts, in part or in whole, from another organization is addressed in b-ITU-T A.25. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of pub
19、lication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below. A list of
20、the currently valid ITU-T Recommendations is regularly published. The reference to a document within this Recommendation does not give it, as a stand-alone document, the status of a Recommendation. None. 3 Definitions 3.1 Terms defined elsewhere This Recommendation uses the following terms defined e
21、lsewhere: 3.1.1 normative reference b-ITU-T A.1: Another document that contains provisions which, through reference to it, constitute provisions to the referring document. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 approved document: An official o
22、utput (such as a standard, a specification, an implementation agreement, etc.) which has been formally approved by an organization. 3.2.2 non-normative reference: The whole or parts of a document where the referenced document has been used as supplementary information in the preparation of the Recom
23、mendation or to assist the understanding or use of the Recommendation, and to which conformance is not necessary. 3.2.3 referenced organization: An organization for which an ITU-T study group identifies the need to make a specific reference (either normative or non-normative) to one of its document.
24、 2 Rec. ITU-T A.5 (02/2016) 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: None. 5 Conventions None. 6 Generic procedures for including references to documents of other organizations in ITU-T Recommendations 6.1 An ITU-T study group or a member of a s
25、tudy group may identify the need to make a specific reference (either normative or non-normative) to a document from another organization within a specific draft Recommendation. It is preferred that, rather than making reference to an entire document from an outside organization, reference be made t
26、o only the specific section(s) concerned. The requirements of clauses 6.2 and 6.3 do not apply for non-normative references, since such referenced documents are not considered to be an integral part of an ITU-T Recommendation. They are documents that add to the readers understanding but are not esse
27、ntial to the implementation of, or compliance with, the Recommendation. 6.2 For normative references, a member submits a contribution, or the Rapporteur or Editor submits a TD, to the study group or working party providing information, as outlined in clauses 6.2.1 to 6.2.10. The study group or worki
28、ng party evaluates this information and decides whether to make the reference. The format for documenting the study group or working party decision is given in Annex A. Specific criteria for the qualification of the considered organization are provided in Annex B. The list of those qualified organiz
29、ations is on the Databases page of the ITU-T website1. 6.2.1 A clear description of the document considered for reference (type of document, title, number, version, date, etc.). 6.2.2 Status of approval. Referencing a document that has not yet been approved by the referenced organization can lead to
30、 confusion; thus, normative referencing is usually limited to approved documents. If absolutely necessary, such a reference can be made where cooperative work requiring cross-references is being approved by ITU-T and another organization in approximately the same time-frame. 6.2.3 Justification for
31、the specific reference. 6.2.4 Current information, if any, about intellectual property rights (IPR) issues (patents, copyrights, trademarks). 6.2.5 Other information that might be useful in describing the “quality“ of the document (e.g., whether products have been implemented using it, whether confo
32、rmance requirements are clear, whether the specification is readily and widely available). 6.2.6 The degree of stability or maturity of the document (e.g., length of time it has existed). 6.2.7 Relationship with other existing or emerging documents. 1 The current website is: http:/www.itu.int/en/ITU
33、-T/extcoop/Pages/sdo.aspx Rec. ITU-T A.5 (02/2016) 3 6.2.8 When a document is to be referenced in an ITU-T Recommendation, all explicit references within the referenced document should also be listed. 6.2.9 Qualification of referenced organization (per clause 7). This need only be done the first tim
34、e a document from the referenced organization is being considered for referencing and only if such qualification information has not been documented already. 6.2.10 A full copy of the existing document. No reformatting is necessary. The objective is to have referenced documents available via the web
35、 at no cost, so that the study group or working party may proceed with its evaluation. Accordingly, if a document to be referenced is available in this manner, it is sufficient for the contributing member to provide its exact location on the web. On the other hand, if the document is not available i
36、n this manner, a full copy must be provided (in electronic format if permissible by the referenced organization, otherwise in paper format). 6.3 For normative references only, the study group or working party evaluates the above information and comes to its conclusions based on the usual consensus p
37、rocess. The decision of the study group or working party shall be documented using the format in Annex A. This requirement must be completed, at the latest, at the time the Recommendation is determined under the traditional approval process (TAP) or consented under the alternative approval process (
38、AAP). The study group or working party report may simply note that the procedures of Recommendation ITU-T A.5 have been satisfied and provide a pointer to the document where the full details reside. 6.4 If the study group or working party decides to make the normative reference, it should be introdu
39、ced with the standard text provided in clause 2 of the “Authors guide for drafting ITU-T Recommendations“. NOTE In the case of texts produced jointly by ITU-T and ISO/IEC JTC 1, it is recognized that clause 6.6 of the Rules for presentation of ITU-T | ISO/IEC common texts2 apply. 7 Qualification of
40、referenced organizations 7.1 To ensure the continued quality of the ITU-T Recommendations, not only is it necessary to evaluate the document being proposed for normative reference, but it is also necessary for the study group or working party to consider the referenced organization according to the
41、criteria set out in clauses 7.1.1, 7.1.2 and 7.1.3. 7.1.1 Qualification of the referenced organization according to Annex B should be conducted before considering a normative reference from that organization. If the referenced organization has already been qualified according to the criteria in Anne
42、x B (or previously to Recommendation ITU-T A.4 or Recommendation ITU-T A.6), the evaluation may not need to be repeated, and only a note of the result is required. 7.1.2 In addition, the referenced organization should have a process by which its output documents are published and regularly maintaine
43、d (i.e. reaffirmed, revised, withdrawn, etc.). 7.1.3 The referenced organization should also have a document change control process, including a clear, unambiguous document numbering scheme. In particular, a feature to look for is that updated versions of a given document be distinguishable from the
44、 earlier versions. 2 The current website is: http:/itu.int/en/ITU-T/about/groups/Documents/Rules-for-presentation-ITU-T-ISO-IEC.pdf 4 Rec. ITU-T A.5 (02/2016) 7.2 Qualification of an organization according to the criteria in Annex B is reviewed on a regular basis by study groups that need to make no
45、rmative references to documents of that organization. In particular, if the patent policy of that organization has changed, it is important to check that the new patent policy is consistent with the Common Patent Policy for ITU-T/ITU-R/ISO/IEC and the Guidelines for the Implementation of the Common
46、Patent Policy for ITU-T/ITU-R/ISO/IEC3. 3 See http:/www.itu.int/en/ITU-T/ipr Rec. ITU-T A.5 (02/2016) 5 Annex A Format for documenting a study group or working party decision (This annex forms an integral part of this Recommendation.) The decision of the study group or working party with respect to
47、making the normative reference must be documented in the meeting record using the following format: 1 Clear description of the document. (type of document, title, number, version, date, etc.). 2 Status of approval: (only approved documents should be considered) 3 Justification for the specific refer
48、ence. 4 Current information, if any, about IPR issues: (including patents, copyrights, trademarks). 5 Other useful information describing the “quality“ of the document: (e.g. length of time it has existed, whether products have been implemented using it, whether conformance requirements are clear, w
49、hether the specification is readily and widely available). 6 The degree of stability or maturity of the document. 7 Relationship with other existing or emerging documents. 8 When a document is referenced in an ITU-T Recommendation, all normative references within that referenced document should also be listed. NOTE A separate review is not required for all of these normative references. However, the referenced organization, if different from ISO or IEC, needs to be qualified under Annex B (and previously under Recommendation ITU-T A.4 or Recommendation ITU-T A.
