Summary

Recommendation ITU‑T Z.166 specifies the control interfaces for TTCN-3 test system implementations. The TTCN-3 control interfaces provide a standardized adaptation for management, test component handling and encoding/decoding of a test system to a particular test platform. This Recommendation defines the interfaces as a set of operations independent of a target language.

The interfaces are defined to be compatible with the TTCN-3 standards (see clause 2). The interface definition uses the CORBA interface definition language (IDL) to specify the TCI completely. Clauses 8 and 9 present language mappings for this abstract specification to the target languages Java and ANSI C. A summary of the IDL‑based interface specification is provided in Anne A.

The first revision of the Recommendation contains amendments (i.e., C++ and C# language mappings), numerous clarifications, corrigenda and editorial corrections.

The first revision of the Recommendation corrects an error in the code specification of Recommendation ITU‑T Z.166 (2011) TCI-CH provided interface in clause 8.5.3.1 in such a way that tciTestComponentRunningReq, tciTestComponentDoneReq, tciTestComponentAliveReq, and tciTestComponentKilledReq all return public Boolean as result.

This second revision of the Recommendation contains amendments, clarifications, corrigenda and editorial corrections.

This Recommendation is technically aligned with ETSI ES 201 873-6 V4.4.1 (2012).
