Abstract:
A method for controlling communications between multiple independent distributed nodes, wherein each other includes a switch, a subscriber circuit, a trunk circuit and a call processor, said method comprising:creating a network of plural nodes, each of said nodes connected to a network for processing communications between said nodes; storing, in each node, a specific data base of call processing information for a specific node in the network of nodes; storing, in each of said nodes, a common data base of call processing information common to all nodes, for the network of nodes, such that each node in the network has call status data for all ether nodes in the network; executing distributed call processing by a plurality of said nodes; converting between physical positions indicating the physical accommodating position of the trunk circuit and subscriber circuit and logical positions independent from the physical positions to thereby control a call control section of the call processor with each node.
