10、ndation 4.784.2 was prepared by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 5th of June 1997. STD-ITU-T RECMN Q-78Li-2-ENGL 1997 9 4b2591 Ob39382 045 W FOREWORD IT (International Telecommunication Union) is the United Nations Specialized Agency

11、in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the IT. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldw

12、ide 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, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by

13、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 with IS0 and IEC. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate

14、 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 this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position conce

15、rning 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 the date of approval of this Recommendation, the ITU haahad not received notice of intellectual property, protecte

16、d 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 urged to consult the TSB patent database. O ITU 1997 All rights reserved.

27、CT TEST SUITE FOR ISUP92 BASIC CALL CONTROL PROCEDURES (Geneva, 1997) 1 Scope This Recommendation contains the validation (conformance) test specification for ISUP92 basic call control and signalling procedures defined in Recommendation 4.764 4. In contrast to Recommendation 4.784.1 131, where the a

28、pproach is informal, this Recommendation presents an Abstract Test Suite (ATS) for ISUP92 basic call, written in TTCN (Tree and Tabular Combined Notation), see 9 and io. While the tests in Recommendation 4.784.1 also cover the ISUP as defined in Recommendation 4.767 5, this Recommendation applies on

29、ly to exchanges having implemented the ISUP92 protocol specification. It is applicable for validation testing of all types of exchanges as defined in the ISUP92 protocol specification. Note that the compatibility tests are covered by Recommendation 4.784.1 131. The main text part of this Recommendat

30、ion presents the requirements regarding the chosen test method, conventions used within the ATS, the Test Suite Structure and the Test Purposes (TSS and TPs) for ISUP92 basic call control procedures. Annexes A, B, C and D present the Protocol Implementation Conformance Statements (PICS), the Protoco

31、l Implementation Extra Information for Testing (PIXIT), Protocol Conformance Test Report (PCTR) and the ATS for ISUP92 basic call control procedures, Annex D being available on electronic media. Annex A provides the Protocol Implementation Conformance Statement (PICS) proforma for the ISUP92 defined

32、 in compliance with the relevant requirements and in accordance with the relevant guidance given in ISOAEC 9646 7 to 12. This statement, of which capabilities and options of a telecommunication specification have been implemented, is necessary for evaluating the conformance of a particular implement

33、ation. Annex B provides the Protocol Implementation Extra Information for Testing (PIXIT) proforma, needed as a preparation for testing. Annex C provides the Protocol Conformance Test Report (PCTR) proforma, used for evaluating the results of the testing campaign. Annex D explains how to get hold of

34、 the actual ATS, which is delivered in electronic form only. 2 References The following ITU-T Recommendations, and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
