ABSTRACT:
In a distributed processing telecommunication switching system comprising a plurality of switching modules, the individual modules control substantially all telephone call control processing actions, including the selection of an available port of a multiport hunt group, without requiring the assistance of a central processor. Each module includes a processor, a plurality of ports connected to customer lines and interoffice trunks, a plurality of outlets for setting up intermodule connections, and a switching network for interconnecting ports and outlets within a module. The module processors communicate with each other by a high speed common data communication facility connected to all processors. This data communication facility is used for communicating intermodule call control messages and port availability data to allow port hunts to be accomplished without using a central processor.
