返されない。The external console 1 performs unified management control of a time division multiplexing device group forming a network. When actually controlling the time-division multiplexing device group or the like, a control signal from the external console 1 is input to the communication control unit 21 and the insert unit 31 is controlled.
The control signal is inserted into the control channel allocated to the transmission line, and the transmission line interface conversion is performed by the interface unit 41 and output. In the time-division multiplexing device on the receiving side, the interface 42 converts the transmission path interface, the drop unit 34 extracts a control signal, and inputs the control signal to the communication control unit 22. If the control content is a return command,
The signal is output to the loopback unit 5 and a loopback test of the transmission path data is executed. The timing generator 6 generates a timing corresponding to the position of the control channel allocated in the loopback data. The control signal insertion unit 7 inserts the control signal from the communication control unit 22 at the position of the control channel allocated on the transmission line in accordance with this timing. Since the control signal from the communication control unit 22 is inserted into the position of the control channel allocated on the transmission path after such a folding unit 5, even if the data is folded, the control signal is not folded.
