Controlling multi-port hunt groups in a distributed control switching system

摘要

A distributed control switching system where multi-port hunt groups are controlled by hunting for idle group members in a sequential fashion starting with the members on one of the switching modules of the system and continuing through a predetermined sequence of modules until an idle group member is found. The busy/idle hunt data is distributed across the modules so that each module maintains the hunt data for only the group members on that module. Therefore, no inter-module control communication is devoted to updating the hunt data of other modules.
