ITU-T Q.3903 (10/2008) i Recommendation ITU-T Q.3903 Formalized presentation of testing results Summary Recommendation ITU-T Q.3903 describes the main requirements for a knowledge base as per testing results formalization on model networks. This Recommendation describe

8、s the principles of knowledge base filling as per testing results formalization, requirements to store various types of testing data and format of data presentation. Source Recommendation ITU-T Q.3903 was approved on 14 October 2008 by ITU-T Study Group 11 (2005-2008) under Recommendation ITU-T A.8

9、procedures. Keywords Knowledge base (KB), model networks, next generation networks (NGNs), public switched telephone networks (PSTNs), testing. ii Rec. ITU-T Q.3903 (10/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommuni

10、cations, information and communication technologies (ICTs). 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 telecommunica

11、tions 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

12、 laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts 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 telecommu

13、nication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. 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 ma

14、ndatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and 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 RIGHTS ITU draw

15、s attention to the possibility that the practice or implementation of this Recommendation may involve 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

16、 others outside of the Recommendation development process. As of the date of approval of this Recommendation, 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 repr
