Abstract

PURPOSE:To control a switchboard with large circuit capacity by a microprocessor by composing a control circuit of several microprocessors and by providing an information transfer line for information transmission among processors and a memory method which executes a switching process and stores data. CONSTITUTION:Trunks 611 to 61n are connected to switching networks 51 to 5m to which extension telephone sets 111 to 11n via line circuits 211 to 21n and attendant boards 311 to 31n via attendant-board control circuits 411 to 41n are connected, and signal control processors 711 to 7m1 controlling signals and connection control processors 911 to 9p1 controlling connections are provided corresponding to those networks 51 to m. Moreover, memory 101 which attains the half-fixed storing of system data is provided and connections among processors 711 to 7m1 and 911 to 9p1, and memory 101 are made via two-way buses 82 and 83 for transferring information; memory 101 is used from either processors 711 to 7m1 or 911 to 9p1 and networks 51 to 5m are divided and controlled.
