Summary

ITU-T Recommendation Z.163 defines the graphical presentation format for the TTCN-3 core language as defined in ITU-T Recommendation Z.161. This presentation format uses a subset of Message Sequence Charts as defined in ITU-T Recommendation Z.120 with test specific extensions.

This Recommendation is based on the core TTCN-3 language defined in ITU-T Recommendation Z.161. It is particularly suited to display tests as GFTs. It is not limited to any particular kind of test specification.

The specification of other formats is outside the scope of this Recommendation.
