Classification: CPC H | IPC H

Claim 11:
12. A network control system, comprising:
a line fault detection device comprising:
a communication device;
a memory storing instructions; and
a processor communicatively coupled to the communication device and the memory, wherein the processor is configured to execute the instructions to:
generate a network device vector, for each line, including communication states of network devices interconnected through the line as elements; and
generate line state information by determining a state of the line based on the communication states; and

a line management device configured to:
receive, from the line fault detection device, the line state information;
measure the state of the line identified from the line state information;
determine the state of the line based on a result of measuring the state of the line; and
provide the determined state of the line to the line fault detection device.
