Abstract: An improved system for effecting broadband/multimedia calls and connections within an intelligent switched telecommunication network. This system, which employs object-oriented commands, is capable of establishing complex call and connection configurations between multiple network subscribers participating in a broadband/multimedia call. These object-oriented commands, which are stored in and initiated from network adjuncts or service control points, eliminate the need for long series of individual low-level commands to be transmitted to the network switching system. Furthermore, the system provides for a finite set of object-oriented commands which are capable of implementing the many complex and diverse interconnections which may be required in effecting multi-party broadband/multimedia calls. This is accomplished by selectively combining various object-oriented commands to produce the connectivity which will support the desired broadband/multimedia call.
