Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. 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 node of a plurality of nodes, each node having network devices connected to both ends of a line as elements;
based on occurrence of a communication alarm, set an element corresponding to a network device in which the communication alarm occurred as a communication state according to the communication alarm and determine a state of the line based on the communication state set on the network device vector;
set the elements of the network device vector generated for each vector so that the network devices connected to each other through the line correspond to each other; and
determine whether a fault occurred in the line based on a result of a logical operation of a pair of network device vectors corresponding to the line, and determine the network device where the fault occurred based on the communication state set in the network device vector.
