The ITU-T is res

3、ponsible 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 every four years, establishes the topics for study by

4、 the ITU-T Study Groups which, in their turn, produce 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 (Helsinki, March 1-12, 1993). ITU-T Recommendation X.295 was prepared by ITU-T Study Group

5、 7 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 10th of April 1995.

17、s which are based on the methodology defined for the base protocol specifications. The text was developed jointly with ISO/iEC JTC1. 11 Recommendation X.295 (04/95) m YB6259L ObOb820 936 INTRODUCTION This Recommendation provides OS1 protocol profile testing methodology based on the protocol testing

18、methodology specified in Recommendation X.291. Recommendation X.290 defines terminology and introduces general concepts for both protocol and profile testing. Recommendation X.293 places requirements on test realization and Recommendation X.294 places requirements on the conformance assessment proce

19、ss, both of which are applicable to profile testing. Recommendation X.296 describes how profile requirements are documented in Implementation Conformance Statements (ICSs) and profile Requirements Lists (Us). A profile specification is a document containing one or more profiles. An International Sta

20、ndardized Profile (ISP) is an example of a standardized profile specification. A profile is defined as the selection of one or more base specifications and the identification of the chosen classes, common subsets, options and parameters of those base specifications necessary for accomplishing a part

21、icular function. Profiles are defined to facilitate interworking between systems implementing the same profile. A profile implementation is tested for conformance to the relevant profile specification in order to give confidence that interworking can be achieved, and to verify that the implementatio

22、n conforms to the profile specification. The meaning of conformance to a profile and the method of expressing profile conformance requirements are described in clause 6. Profile testing principles, based on the methodology defined for the base protocol specifications, are described in clause 7. The

23、Profile Test Specification (PTS) is the complete set of documents needed to specify conformance testing for a profile. The PTS is based on the Abstract Test Suite (ATS) specifications of the protocols referenced by the profile. The PTS is described in clause 7. The PTS-Summary provides, in a single

24、document, references to all the elements of the PTS. The PTS-Summary is described in clause 8 and a template for a PTS-Summary is described in Annex A. The Profile Specific Test Specification (PSTS) contains any changes to the ATS specifications relevant to the base specifications and the additional

25、 test cases required for the profile testing. The PSTS is described in clause 9. This Recommendation is also published as ISO/IEC 9646-6: 1994. .

26、) (1995) PROTOCOL RECOMMENDATIONS FOR ITU-T APPLICATIONS - PROTOCOL 1 Scope This Recommendation specifies the requirements and provides guidance for the production of Profile Test Specifications (PTSs) for conformance testing of OS1 protocol profiles. This Recommendation also specifies requirements

27、concerning the expression of conformance requirements in protocol profile specifications. This Recommendation is applicable to testing the conformance of a profile implementation to the static and dynamic conformance requirements of each protocol and any information objects included in the profile,

28、by controlling and observing Protocol Data Unit (PDU) exchanges. Testing requirements that go beyond conformance are outside the scope of this Recommendation. 2 References The following Recommendations and other references contain provisions which, through reference in this text, constitute provisio

In addition, the following definition applies to this Recommendation: 3.1 component (of a profile): A component of a profile is a single protocol or a combination of one or more proto

42、cols with zero or more information objects upon which a profile is based and which are to be tested in combination. 4 Abbreviations For the purposes of this Recommendation, the following abbreviations defined in Recommendation X.290 apply: ATM Abstract Test Method ATS Abstract Test Suite ICs Impleme

47、 refers. For example, when a feature is associated with an allowed parameter value range, the profile shall only adopt the same value range as that allowed by the base specification, or a subset of that range. Therefore, conformance to that set of base specifications does not necessarily imply confo

48、rmance to the profile. However, conformance to a profile implies by definition conformance to the set of base specifications which it references. 6.2 Profile conformance requirements 6.2.1 Introduction The concepts of static conformance and dynamic conformance apply also to profiles. 6.2.2 Static co

49、nformance requirements clause In order to ensure consistency between profiles and base specifications, the static conformance requirements of a profile shall be specified, where possible, by reference to the conformance requirements of the referenced base specifications. There shall be a static conformance requirements clause in a profile, structured as follows: a) an overview of the major subsets or implementation categories which provides an overall rationale for the more detailed selection of classes
