Abstract: A program-controlled telephone switching system which includes a main processor which serves to control the system''s switching network and to process data obtained by the main processor and data obtained by an auxiliary processor. The auxiliary processor comprises a control unit and a memory which is directly shared by the main processor and the auxiliary processor. The auxiliary processor operates in accordance with programs and data placed in the shared memory by the main processor and by means of such programs and data examines the lines and trunks of the system to detect significant changes which are indicative of a request for attention by a line or trunk. Upon detection of a significant condition, the auxiliary processor places a record in the shared memory which identifies the line or trunk which has experienced a significant change.
