Summary

This ITU-T Recommendation describes the TMN interface specification methodology UTRAD (Unified TMN Requirements, Analysis and Design). It describes the process to derive interface specifications based on user requirements, analysis and design (RAD). Guidelines are given to describe RAD using Unified Modelling Language (UML) notation; however, other interface specification techniques are not precluded. The guidelines for using UML are described at a high level in this ITU-T Recommendation.
