ABSTRACT:
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.
