Abstract

PURPOSE:To diagnose operations of all channel units easily at an optional point in time by adding a detecting function of item-by-item monitoring to every section and by using their detection signals direct or in combination. CONSTITUTION:When a voice signal is inputted to PCM coder 10, voice derecting circuit 20 detects that and outputs voice detecting signal B. Next, transmitted IF output detecting circuit 21 generates a transmitted carrier on signal. This signal and signal B are sent to logic circuit 30. When a received signal enters demodulator 16, on the other hand, acquisition detecting circuit 23 generates the rise (SOM) detecting gate of information. Next, the SOM detection signal is extracted via SOM detecting circuit 25 and this signal is passed through AND circuit 24 by the SOM detecting gate to extract the SOM signal. This signal and SOM detecting gate are sent to circuit 30. Each detection signal sent to circuit 30 is counted by counter 31 in every prescribed time and recorded 32.
