Abstract :
In order to establish rapid diagnosis in a signaling service, this study has developed a system which can analyze the status of the signal sent from/received by signaling equipment, providing for a fully electronic switching system such as TDX. The system has a function of acquiring the PCM signal of the preferred channel from the subhighway (SHW), and then it classifies the type of signal such as R2MFC/DTMF/CCT/VOICE, and finally discriminates the digit
