29、ttees having a special interest therein are represented, express, as nearly as possible, an international consensus of opinion on the subjects dealt with. They have the form of recommendations for international use and they are accepted by the National Committees in that sense. In order to promote i
30、nternational unification. the IEC expresses the wish that all National Committees should adopt the text of the IEC recommendation for their national rules in so far as national conditions will permit. Any divergence between the IEC recommendation and the corresponding national rules should, as far a
31、s possible, be clearly indicated in the latter. Chapters of the International Electrotechnical Vocabulary (IEV) relating to telecommunications (chapters of the 700 suies) have been prepared by Joint Groups of experts from the technical committees of the international Telecommunication Union (UIT) -
32、international Consultative Radiocommunications Committee (CCIR). International Cqnsultative Telegraph 8nd Tekphone Committee (CCI?T) - and from the Intanational Electrotechnical Commission (EC). amdtiated by the CCIRcCT-EC Joint Co-ordinating Group for vocabulary (JCG). The terms and definitions in
33、these chapters are intended to promote a good understanding of telecommunications texts. They have been approved for publication by the IEC National Committees. They have not received formal approval by the CCIR or CCIT“ Plenary Assemblies and do not replace definitions contained in CCIR or CCITT re
34、commendations (or in the Radio Regulations, the International Telecommunication Regulations. or the International Telecommunication Constitution or Convention) which are to be used in their respective fields of application. This international Standard has been prepared by a group of experts of the J
35、CG under the responsibiiity of IEC technical committee 1: Terminology. It forms Chapter 705 of the International Electrotechnical Vocabulary (IEV). The text of this standard is based on the following documents: Full information on the voting for the approval of this standard can be found in the repo
