INTERNATIONAL TELECOMMUNICATION UNION A.13 TELECOMMUNICATION STANDARDIZATION SECTOR OF ITU (10/2000) SERIES A: ORGANIZATION OF THE WORK OF ITU-T Supplements to ITU-T Recommendations ITU-T Recommendation A.13 (Formerly CCITT Recommendation) ITU-T Recommendation A.13 Supplements to ITU-T Recommendations Summary This Recommendation describes Supplements to ITU-T Recommendations. Source ITU-T Recommendation A.13 was prepared by TSAG (1997-2000) and approved by WTSA (27 September – 6 October 2000). ITU-T A.13 (10/2000) i FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization 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 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-T's purview, 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. ã ITU 2001 All rights reserved.

Normally, any information that is considered as merely illustrative or supplementary to a Recommendation should be included as a (non-integral) Appendix to that Recommendation, where it is useful to the wider audience. However, there are exceptional instances where separate publication of such information is warranted, in the form of Supplements to the Recommendations. 2 Supplements The following general principles shall be applied by study groups for the development, approval, identification and revision of Supplements: 2.1 Before proposing any new or revised text as a Supplement, a study group or TSAG should ensure, in consultation with the Director, that: i) the subject matter is within its mandate; ii) there is a sufficient need for the information on a long-term basis; iii) the text cannot be reasonably adapted for inclusion in an existing or new Recommendation (e.g. as an appendix); iv) the text is sufficiently mature and that the text follows, as far as possible, the format of the "Author's Guide for drafting ITU-T Recommendations"; v) the text contains material which is supplementary to and associated with the subject matter of one or more Recommendations but is not essential to their completeness or understanding and implementation. 2.2 Supplements do not require approval according to Resolution 1 or Recommendation A.8 procedures; agreement by the study group or by TSAG (in case of a Supplement developed by TSAG) is sufficient. 2.3 Supplements should be limited in number and volume. 2.4 Supplements are only informative and are therefore not considered to be an integral part of any Recommendation(s). They do not imply any agreement on the part of ITU-T. 2.5 Each Supplement should be unambiguously identified by the series letter to which it is associated followed by a sequential number unique within that series. 2.6 Since Supplements are essentially reference material, no onus is implied on the issuing study group to update or to reissue Supplements. However, should reference to a Supplement be made in a Recommendation, the study group should review the applicability both of that reference and the Supplement at least once every four years, and take any necessary action.
