Control apparatus, control system, control method, and non-transitory computer readable medium

A control system comprising:

• a monitoring apparatus;
• and
• a control apparatus, wherein
• the control apparatus comprises:
• at least one memory storing instructions;
• and
• at least one processor configured to execute the instructions to:
• instruct the monitoring apparatus to perform processing for monitoring a submarine cable;
• and
• control a submarine device connected to the submarine cable,
• the monitoring apparatus, in response to the instruction given by the control apparatus, sends a monitoring signal into the submarine cable and performs the monitoring processing, and
• the at least one processor is configured to execute the instructions to detect a timing at which the monitoring processing is not being executed, and then send a control signal into the submarine cable and control the submarine device.

A control method comprising:

• instructing a monitoring apparatus to perform processing for monitoring a
• submarine cable;
• and
• controlling a submarine device connected to the submarine cable, wherein
• the monitoring apparatus, in response to the instruction given to the monitoring apparatus, sends a monitoring signal into the submarine cable and performs the monitoring processing, and
• in the controlling of the submarine device, a timing at which the monitoring processing is not being executed is detected, and then a control signal is sent into the submarine cable and the submarine device is controlled.
