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 of [ETSI ES 201 873-6 V4.5.1]). The interface definition uses the CORBA Interface Definition Language (IDL) to specify the TCI completely. Clauses 8, 9, and 9.7 of [ETSI ES 201 873-6 V4.5.1] present language mappings for this abstract specification to the target languages Java and ANSI C.
This revision of the Recommendation contains amendments, clarifications, corrigenda and editorial corrections.
