An arrangement for pooling service circuits so that they become available to a plurality of switching systems in a telecommunications network. A regional control node receives a request for a service circuit to be connected to a call. The regional control node maintains the availability status of the service circuits in a pool for the region. In response to a request for a service circuit, the regional control node selects an appropriate circuit and transmits order to the switches and the circuit to establish the proper connections among these units in order to associate the service circuit with the requesting call. Advantageously, such an arrangement permits a large pool of individually expensive service circuits to serve a large number of switching systems, thus, increasing the efficiency of utilization of these service circuits. The arrangement is also used for controlling the allocation of transmission resources to any call, thus optimizing the use of the regional transmission resources.

Service circuit allocation in large networks

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.
