ABSTRACT:
The invention relates to a distributed control-type electronic switching system which includes a first group of processors paired for act/standby redundancy, and a second group of master processors which are provided as single units. The first group of processors is connected to the speech-path switches and line and trunk circuits of a telephone switching system while the second processor group controls the various connections for the speech-path switches and the line and trunk circuits. Data communications between the first group of processors and the second group of processors is achieved on a distributed basis such that each processor of the first group designates a subset of the second group of processors as potential receivers, and conducts communications with the first non-busy processor of the subset.
