ABSTRACT:
A toll programming system includes a plurality of processors having individual memories and sharing a common memory for controlling a toll telecommunication switching system by executing a plurality of programs divided in a first and second series. Each program of the first series is executed by one processor only (function distribution), whereas each program of the second series is executed by two or more processors (load sharing). In the latter case, conflicts are resolved by the use of treated-by-me tables. The processors employ mask words in their memories to enable them to distinguish which programs they may execute.
