The mode switch 111 is composed of a level trigger and an external key switch, the level trigger is respectively connected with the information decoding circuit 3, the data conversion circuit 4 and the data processing circuit 5, and each circuit determines the telephone mode accessed by the mode switch 111 by judging the state of the connected level trigger. The mode switch 111 is operated to match the mode switched by the mode switch 111 with the type of telephone accessed from the telephone line access port. The machine body 1 is provided with:
and a signal conditioning circuit 2, wherein the signal conditioning circuit 2 performs signal conditioning on telephone information input from the telephone line inlet 11. Signal conditioning is to amplify telephone information input at telephone line inlet 11 to buffer or scale the analog signal to be suitable for input to information decoding circuit 3 or data conversion circuit 4. When the mode switch 111 is switched to the program-controlled telephone mode, the telephone information after signal conditioning is sent to the information decoding circuit 3, and when the mode switch 111 is switched to the magneto telephone mode, the telephone information after signal conditioning is sent to the data conversion circuit 4.
And when the mode switch 111 is switched to the program-controlled telephone mode, the information decoding circuit 3 receives the telephone information conditioned by the signal conditioning circuit 2, performs ringing detection, on-line detection and on-hook detection on the telephone information, acquires telephone detection information and sends the telephone detection information to the data conversion circuit 4. Specifically, when the information decoding circuit 3 detects the telephone information after signal conditioning sent by the signal conditioning circuit 2, and when it is detected that the waveform of the telephone information signal after conditioning is a sine wave, the frequency is 25Hz ± 3Hz, the output voltage is 75V ± 15V, and a signal with a distortion degree of less than 1% is a ringing signal, the ringing signal is recorded and sent to the data conversion circuit 4. The information decoding circuit 3 also monitors the on-hook and off-hook states of the telephone through periodic scanning of the telephone information conditioned by the signals, and records the on-line information and the on-hook and off-hook information formed by corresponding events and sends the on-hook and off-hook information to the data conversion circuit 4 when the on-hook and on-hook states of the telephone are found to change.
