Abstract
PURPOSE:To shorten the recovery time by automatically executing the maintenance such as a fault diagnosis, etc. by the remote control, and informing the diagnostic result to the other station, in the communication equipment such as a facsimile, etc. CONSTITUTION:The 6 loops are formed by the transmission system and the receiving system of the facsimile communication equipment, the loop test is executed in the direction from the receiving system to the transmission system, the loop test of each block is executed in accordance with the loop test instruction from the other station by the control circuit 30, whether its operation is normal or not is decided, and it is output. Its loop test result is transmitted to the other station. The result of the loop test is decided freely by the other station. In case when a fault has occurred in the equipment, the circuit block in which a fault has occurred can be detected.
