Abstract

PURPOSE:To ensure the relay by the substitute of the slave station even in case the central station is broken down, by providing the backup function and the program of the central station to the specified slave station. CONSTITUTION:For one sheet of switch on which change-over switches 18-1-a and 21-1-a are put in correspondence to each other, the constant-open contacts of them are connected mutually via connection lines 22-1-a-22-N-a. Accordingly, the data delivered from slave station 13-1 reaches backup station 13-N via junction line 15-1-a, connection lines 16-1-a, 22-1-a and 20-1-a plus repeater station 15-M- 1-a in that order when the switching is given to the contacts of all switches 18-1- a-21-N-a. Station 13-M possesses the control memory at the backup time in addition to the memory of the ordinary time, and thus connects the CPU to the control memory through the bus line in case subject 14 at the exchange part of the central station is broken down in order to substitute the central exchange station in the form of the control at the faulty time.
