Abstract

PURPOSE:To obtain an economical switchboard system, by providing a processing part to each function block which forms a switchboard system and securing an interface between the blocks by the loop connection. CONSTITUTION:A switchboard shown in the figure includes the subscriber sybsystems 20 and 30 which give the time division line concentration to the subscribers 200-301, a network subsystem 40 using a time division switch, a register subsystem 50, trunk subsystems 60 and 70, a central control subsystem 10, an operation subsystem 90 and a maintenance subsystem 80. Each of these subsystems contains processing parts 21, 31, 41, 51, 61, 71, 81 and 91 plus a central control processor 11 that control the job proper to each function. these subsystems are connected to each other by loop communication lines 00 and 01 and via loop communication control circuits 22, 32, 42, 52, 62, 72, 82, 92, 12 and 13 respectively to transmit and receive the necessary control information. The subsystem 10 gives the centralizing control to the operations of other subsystems.
