2、TIONS IMPLEMENTATION CONFORMANCE STATEMENTS FOR ITU-T APPLICATIONS - ITU-T Recommendation X.296 (Previously “CCITT Recommendation”) ITU-T RECMN*X*29b 95 4862591 0618061 984 FOREWORD The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union

3、 (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommen- dations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets eveq four years, establishes

4、the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the U-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12.1993). lTU-T Recommendation X.296 was prepared

5、by -T Study Group 7 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 21st of November 1995. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. O 1996

An IC

25、s contains necessary information required for conformance testing specified in OS1 specifications and related profiles. INTRODUCTION Recommendation X.290 defines terminology and introduces general concepts for both protocol and profile testing. Recommendation X.291 specifies the requirements on the

26、production of OS1 conformance testing standards and standardized abstract test suites. Recommendation X.292 defines a standardized test notation, the Tree and Tabular Combined Notation (TTCN) for the specification of a standardized Abstract Test Suite. Recommendation X.293 places requirements on tes

27、t realization, and Recommendation X.294 places requirements on the conformance assessment process. Recommendation X.295 specifies requirements for the production of OS1 protocol Profile Test Specifications. This Recommendation specifies requirements for the development of Implementation Conformance

28、Statements (ICSs) for protocols, profiles and information objects (such as managed objects). An ICs contains the necessary information required for conformance testing to the relevant requirements specified in OS1 specifications and their related profiles. The ICs proforma is in the form of a questi

29、onnaire or check-list that is intended to cover all requirements, all optional and conditional functions, elements of procedure, parameters, PDUs, timers, etc. and other capabilities identified in the specification. The ICs proforma is to be completed by the supplier or the implementor. An overview

30、of the System Conformance Statements (SCSs), ICSs and their proforma is discussed in clause 6. Clause 7 describes the structure of the SCS proformas. Clause 8 discusses requirements and layout of ICs proforma specifications and profile Requirements Lists (RLs). Clause 9 provides a complete specifica

31、tion for ICs proformas, as well as profile RLs, and describes requirements on the notation. Appendix I provides guidance on the meaning of ICs status values and support answers. Appendix II provides examples of profile RLS and profile specific ICSs. Appendix IIi provides examples of PICS proforma ta

32、bles and profile RL tables. Appendix N provides guidance for interpreting additional status information. Appendix V provides guidance on WT proformas. Appendix VI provides information on information objects. Appendix W provides guidance on multi-specification dependencies. Appendix WI provides guida

33、nce on status values for parameters on received Protocol Data Units. Appendix IX provides guidelines on ICs templates.

34、TS FOR PROTOCOL RECOMMENDATIONS FOR ITU-T APPLICATIONS - (Geneva, 1995) 1 Scope This Recommendation gives guidance on the concepts of Implementation Conformance Statements (ICSs) and System Conformance Statements (SCSs) related to OS1 specifications and specifies requirements and gives guidance on t

35、he production of ICs, ICs proformas, ICs templates and profile Requirements Lists (RLs). This Recommendation specifies for these documents, the structure, the questions to be asked, the syntax and notation to be used and the semantics of the questions and expected answers. No generic ICs template is

36、 provided because of the wide variety of OS1 specifications for which conformance requirements are stated. Nevertheless, this Recommendation provides general requirements that are applicable to any OS1 specification. Other than guidance on the relation between ICs and Implementation extra Informatio

37、n for Testing (KIT), requirements and guidance on D(rr are outside the scope of this Recommendation. 2 References The following Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
