ITU-T Recommendation Q.816.2 defines a set of TMN CORBA services required to support service-oriented interfaces. It specifies how the ORB and common object services should be used in a lightweight fashion for supporting service-oriented interfaces, and defines extensions to the TMN-specific support services defined in ITU-T Recommendations Q.816 and Q.816.1. A CORBA IDL module defining the interfaces to the new TMN-specific support services is provided. The new services and the lightweight use of other CORBA services, along with ITU-T Recommendation X.780.2, compose a framework for CORBA-based service-oriented TMN interfaces with a wide range of applications.
