ITU-T Z.165 (10/2017) i Recommendation ITU-T Z.165 Testing and Test Control Notation version 3: TTCN-3 runtime interface (TRI) Summary Recommendation ITU-T Z.165 provides the specification of the runtime interface for TTCN-3 (Testing and Test Control Notation 3) test system implementations. Th

7、e TTCN-3 Runtime Interface (TRI) provides the recommended adaptation for timing and communication of a test system to a particular processing platform and the system under test, respectively. This Recommendation defines the interface as a set of operations independent of target language. The interfa

8、ce is defined to be compatible with Recommendation ITU-T Z.161. This Recommendation uses the Common Object Request Broker Architecture (CORBA) Interface Definition Language (IDL) to specify the TRI completely. Clauses 6, 7 and 8 of ETSI ES 201 873-5 V4.8.1 specify language mappings of the abstract s

9、pecification to the target languages Java and ANSI-C. A summary of the IDL-based interface specification is provided in Appendix A of ETSI ES 201 873-5 V4.8.1.

ITU-T Z.165 (10/2017) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field o

13、f telecommunications, 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

14、telecommunications 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

15、the procedure 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 bot

16、h a telecommunication 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

17、all of these mandatory 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

18、RIGHTSITU draws 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

19、ITU members or 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 thi

20、s may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2017 All rights reserved.
