ABSTRACT:
A common control for a community office (C.O.) switching system includes two interactive processors. A call control processor comprises the uppermost element in the control hierarchy and is a stored program processor that controls call progression, marks paths through a matrix switch network, and performs other functions. A port event processor constructed of "combinatorial logic" is sequentially coupled to every port equipment position connected thereto over a four millisecond scan cycle. Interaction between the call control processor and the port event processor is effected through a port data store, which provides an individual port data file per port equipment position. The port event processor also includes timers that respond to call timing information that can be stored in a port data field for controlling the processing of certain signals from the corresponding port equipment position.
