11、2.571 063b828 921 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and

12、 tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, pr

13、oduce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis w

14、ith IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of

15、this Recommendation may involve the use of a claimed Intellectual Property Right. The 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 t

16、he date of approval of this Recommendation, the ITU had/had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly ur

20、/ITU TelecommunicationsLicensed by Information Handling ServicesRecommendation 1.1 13 VOCABULARY OF TERMS FOR BROADBAND ASPECTS OF ISDN (revised in 1997) 1 Introduction This Recommendation consists primarily of those terms and definitions that are considered essential to the understanding and applic

21、ation of the principles of broadband aspects of the integrated services digital network (B-ISDN). They are not exclusive to B-ISDN and are recommended also for application, in so far as they are relevant, to other types of telecommunication networks. Included are terms that may already be defined in

22、 other ITU-TATU-R Recommendations. However, the definitions given here embrace only the essential concepts and on that basis it is considered that they are not inconsistent with the more specialized definitions that appear in those Recommendations. According to the conventions applied in this Recomm

23、endation, any term in common usage, but whose use is deprecated, is shown in brackets as in the following example: “broadband wideband“. Where a truncated term is widely used in an understood context the complete term is quoted following the colloquial form, for example, “contribution, contribution

24、application“. Some definitions include terms in italics face to indicate that these terms are defined elsewhere in this Recommendation. Annex A contains an alphabetical list of all the terms contained in this Recommendation. Annex B contains a list of abbreviations which are used in B-ISDN Recommend

25、ations. 2 Vocabulary of terms This clause is divided into subclauses. Within each subclause the terms are listed and defined. 2.1 Services 101 broadband wideband F: large bande S: banda ancha Qualifying a service or system requiring transmission channels capable of supporting rates greater than the

26、primary rate. 102 service bit rate F: dbit de service S: velocidad binaria de servicio The bit rate which is available to a user for the transfer of user information.
