<P>PROBLEM TO BE SOLVED: To decide whether the receiving level of a transmitted signal from a base station is an appropriate level corresponding to the distance from the base station. <P>SOLUTION: In a control part 47 of an ODU (outdoor unit) 40, a receiving level calculating part 471 calculates a receiving level corresponding to a distance between its own equipment and a base station 10 on the basis of parameter data inputted from a maintenance terminal 30 through a terminal 40 for a control signal. A receiving level detecting part 462 detects the receiving level of the transmission signal from the base station 10. A comparing/decision part 463 compares the difference between the calculated receiving level and the detected receiving level with a specified value and decides whether a receiving state is abnormal on the basis of the comparison result. A decision result notifying part 464 notifies the maintenance terminal 30 of the comparison/decision results. The maintenance terminal 30 displays on a displaying part notification that an abnormal state occurs in the receiving state base on the notification from the ODU 40. <P>COPYRIGHT: (C)2003,JPO |
