This Recommendation 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 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 Rec. X.780.2, compose a framework for CORBA-based service-oriented TMN interfaces with a wide range of applications.
