Abstract
PURPOSE:To enable to use th same control system independently of the line capacity and number of functions, by constituting the central control circuit of the exchanger with a plurality of small sized processors. CONSTITUTION:The signal control processors 711 to 7ml have the functional blocks as the line control block, attendant board control block, and trunk control block, and they are provided corresponding to the line circuit, main line attendant board and trunks. The connection control processors 911 to 9P1 are the processors performing connection control such as call connection, subscriber connection, main line incoming and outgoing connection, automatic transfer connection, and abbreviated dial connection, and it is constituted so that the control information transfer with all the signal control procesors can be made, and the processor having the function depending on the starting types is started and processing is made. The information required for the system is memorized in the data memory 101.
