Abstract
A call processing method for distributed switching which substantially increases the percentage of calls that are intra-module calls by distributing the members of trunk groups among a plurality of switching modules and biasing the processing of a call originating on one switching module such that an available trunk group member on that same switching module is assigned to the call if possible. The path hunt function for intra-module calls is separated from the corresponding function for inter-module calls and only the latter function is performed by the system central control. The separation is achieved by dividing the set of switch path resources, e.g., channels or time slots, associated with a switching module into two disjoint subsets--a first subset for intra-module call connections and a second subset for inter-module call connections.
