MSC Connectors as abstractions of the flow of messages between MSC constructs have two fields of application. They show their usefulness in the area of the component-oriented system development where the communication between MSC components, mostly given as MSC references in High Level MSCs or as decomposed instances, is designed as interface protocol of the involved components. But they also provide a means to describe the interaction between MSC constructs such as inline operator expressions or plain instances. This paper elaborates on the semantics definition of the MSC connectors and the specific rules for their application to individual MSC constructs.
