Abstract

PURPOSE:To automatically perform the operation of test for specified positions and the self-diagnosis, by storing the diagnosis program for failure detection and the test program for test operation to the memory unit, in toll type public telephone sets. CONSTITUTION:To the control circuit MCC performing various control with the signal from each circuit realizing the function of telephone set, the processor CPU1, auxiliary memory RAM1, input and output circuit I/O1, and fixed memory ROM1 storing the diagnosis program performing the detection of failure for predetermined inspected positions and the test program performing the test operation, are provided. Ahead the use of a telephone set, when off-hook is made, a signal is given from the hook switch H, the auxiliary memory RAM1 is cleared, and each output signal is reset. Next, the processor CPU1 reads out the diagnosis program from the memory ROM1 to sequentially execute the detection of failure.
