Abstract

PURPOSE:To ensure the economization of the device as well as increase the reliability of the circuit network, by securing the shared control for the 1st-kind control station via the 2nd-kind control station and then setting the above sharing via the control of the 3rd-kind control station each for the circuit switching. CONSTITUTION:At the circuit switching time, 1st-kind control station 1 sends the data of the stand-by circuit memorized in its own station to 2nd-kind control station 2 via 1st-kind control line 4. Then control station 2 secures the combined gathering between the stand-by circuit memorized in the self-station and that sent from station 1 to then send it to single 3rd control station 6 along with the circuit switching information which is calculated and memorized previously for the switching in case the fault occurs. Based on the information given, station 6 decides the proper and direct control for station 1 via station 2 in terms of operation of the control system, and then sends the information to decided station 2 via 3rd-kind control line 7. In such constitution, the memory capacity can be reduced for both stations 1 and 2, and the reliability can be increased for the circuit switching since station 6 control the control system only.
