Abstract
PURPOSE:To reduce the number of controllers, by adding a selection means and by providing a controller for network control in the information processing unit (CPU). CONSTITUTION:Controllers NCUA and NCUA' for control unit which occupy one I/O channels IOCHC and IOCHC' for control of information processing units CPU and CPU' are connected to one I/O channels IOCHC and IOCHC' for control of corresponding CPU and CPU'. I/O channels IOCH1, IOCH2, IOCH1', and IOCH2' for communication in CPU and CPU' are connected to network control units NCU1, NCU2, NCU1' and NCU2' through communication control units CCU1' and CCU2' and MODEMs MODEM1, MODEM2, MODEM1', and MODEM2'. One of NCUs is connected to the NCU for information transmission and receiving light by selecting units SW and SW', thus performing connection control without increasing the number of NCUAs.
