ABSTRACT:
Whether or not the provisioning of a given BRI is properly administered is determined by providing a collection of processes which exercise the known network provided supplementary services in a predetermined fashion. Specifically, a predetermined, i.e., algorithmic, process is employed to examine an administration database to determine which DSLs are to support supplementary services and, then, the process invokes a plurality of processes which attempt to activate the expected supplementary service. The basic mode of operation is to generate a connectivity context in which the supplementary service can be invoked and, then, cause the service to be invoked. ISDN messages are transmitted to the network over the D channel of the given BRI both to establish the service context and, then, to invoke the supplemental service. By analyzing the processes and ISDN messages the system can determine if the desired supplementary services are available, and the results of the analysis are recorded and made available to an operator.
