Abstract:
1. A method for controlling a communication system based on at least one monitored item of the communication system in which a first communication device communicates with a second communication device through a transmission line, the method comprising: setting at least two fault-detection thresholds for the monitored item, wherein the fault-detection thresholds are used for detecting different types of faults; transmitting first data from the first communication device to the second communication device through the transmission line according to an operation timing synchronized between the first and second communication devices, thereby the second communication device receives second data from the first communication device through the transmission line; generating a measured value for each monitored item based on the first data and the second data; comparing the measured value with at least one of the fault-detection thresholds set for the monitored item to determine whether a fault occurs; and when it is determined that a fault occurs, performing recovery of the communication system depending on the fault based on the first data and the second data.
