Abstract

PURPOSE:To omit the synchronous processor and to enable swithcing of the devices by carrying out the regeneration and restoration process of the state at the switching time of the channel system devices when the fault process is carried out. CONSTITUTION:The process system is formed by installing the channel device state regeneration means comprising trunk memory 102, call process control information 103 and regeneration pattern converter 104 to the trunk, several units of channel terminal device 1, stand-by channel system device 2 and central processor CPU3 of the program control electronic exchange system containing the switching function to device 2 when the fault occurs at device 1. CPU3 discontinues the call process action when receiving the fault information from device 1 and gives the initial setting to device 2 to secure the correspondence to the circuit stored in device 1, and then regenerates the call process information via the channel system device regeneration means and based on only the call information to be controlled at CPU3. In such way, the regenerated state is restored to channel device 21, trunk 22 and terminal processor 23 by the channel system order via signal reception distributor 25 and transmission/reception buffer 24. As a result, the process system can be simplified, at the same time shortening the switching time.
