Abstract

PURPOSE:To simplify the redundancy constitution of a system by making a channel unit and controller into multiple constitution. CONSTITUTION:A supervision over subscribers admitted by remote line-concentration unit 20 is exercised automatically by in-use line concentration controller 23a and its data sent to in-use main controller 28a. In this case, line concentrator 22a and transmission line 25a and used sharing a load with line concentrator 22b and transmission line 25b and at a normal time, rates of utilization of transmission lines are equal. Analog-circuit-corresponding part 40 is also doubled by highway switches 27a and 27b and in-use controller 43a controls multiplexers 41a and 41b to equalize the rates of utilization of switches 27a and 27b. Digital-circuit-corresponding part 50 is the same. It is therefore required only to constituting switch capacities 27a and 27b on the basis of the normal-time operation, and the doubling in-use-standby constitution is unneeded.
