Title:
COMMUNICATION RELAY DEVICE, COMMUNICATION RELAY SYSTEM, METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2018011137
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve a synthesized noise value in a master unit and construct an excellent communication environment even when a plurality of slave units are connected to one master unit and an optical repeater system is constructed.SOLUTION: A communication relay device of one embodiment can be connected with a plurality of slave stations. When relay of communication is performed among the plurality of slave stations and a master station, a threshold value level setting section sets a threshold value level for determining whether or not uplink signals are received from the slave stations according to the connection number of slave stations in an updatable manner, a determination section determines whether or not the uplink signals are received from the slave stations based on the set threshold value level, and a transmission prohibition section prohibits transmission of the uplink signals to a master station side when the uplink signals are determined not to be received by the determination section.SELECTED DRAWING: Figure 3
