Abstract

PURPOSE: To eliminate the trouble of measurement item switching and long-time supervising and nonefficiency and to perform maintenance operation efficiency by measuring various characteristic values of a subscriber line periodically within a constant time and recording the generation time and item of a fault automatically.
CONSTITUTION: Necessary items such as a timing time for determining the period of measurement for a certain time where the subscriber line is monitored by an operation part 158 are set and a start button is pressed. An MPU 152 sends a selector control signal to a signal distribution part 14 by a measurement and recording program 156 and a digitized measured value is recorded in a recording area 154. Then the measured value is read out of the measured value recording area 154 and when the measured value is not smaller than a reference voltage, it is judged that trouble occurs and the current time and trouble item are recorded in a trouble recording area 155. When a person in charge of maintenance supplies a display instruction to the MPU 152 from the operation part 158, the trouble item and generation time recorded in the trouble recording area 155 are printed out from a display part 159.
