Abstract

PURPOSE:To improve the efficiency of the maintenance operation function, by storing a voice output, which concerns maintenance operation infomation corresponding to supervisory alarm information, with a digital code pattern and by converting this pattern to an analogue signal in accordance with supervisory alarm information and outputting the analogue signal. CONSTITUTION:The voice output concerning maintenance operation infomation corresponding to supervisory alarm information is stored in a storage device MEM with a digital code pattern and is converted to an analogue voice signal in accordance with supervisory alarm information by a D/A converter DAC. That is, supervisory alarm information from a telephone exchange system EX is gathered by a supervisory alarm circuit SUP, and a voice signal for maintenance operation information is generated in the storage circuit MEM and the D/A converter DAC in accordance with supervisory alarm information by the control by a supervisory alarm control circuit CTL and is amplified by an amplifier AMP and is outputted from a speaker SP.
