Question 3/I - Terminology (continuation of Question 3/II, 1985-1988) Considering (a) that the purpose of terminology work in the CCITT is to define the terms used in CCITT Recommendations to contribute to a better understanding of these Recommendations; (b) that the preparation of Recommendations for new services normally require a consistent vocabulary and agreed definitions to be applied; (c) that certain existing definitions may need to be modified, taking into account changes in technology; (d) that easy reference to definitions should be possible, especially for those general definitions applicable for the work of the whole Study Group; (e) that continuous effort should be made to establish consistency in the terminology of various non-voice Recommendations, the evaluation and on-going study of appropriate terminology in the field of non-voice services should be performed in a coordinated fashion. The aim is to have the appropriate experts develop the definitions of the relevant terms in their F-Series Recommendations and to include them in the Recommendation in which the term is used and/or in a separate Recommendation or Supplement in the F-Series dedicated to terminology. (Refer to Supplementary No. 1 of the F-Series Recommendations.)
