Abstract:
A telecommunications system comprising:M terminating nodes which receive switched permanent connections, where M is an interger; N originating nodes which request switched permanent connections, where N is an interger; a network through which the connections between the originating nodes and the terminating nodes are established, wherein each connection at its terminating node and originating node is permanent and the connection between them is dynamically established using signaling procedures and an optimal routing path, said terminating nodes and originating nodes are connected to the network; and a mechanism for manipulating the order in which the connections are released when there is a failure in the network and established connections fail, the manipulating mechanism having a list of the switched permanent connections, each connection has a priority and a service category and the manipulating mechanism releases connections based on the priority and the service category of the connections, the manipulating mechanism releases the connections having service categories of voice or video before connections having service categories of data.
