Abstract

PURPOSE:To prevent unrequired conversation at an extension telephone set side from leaking or speech at a central office side from being left at a nonaudio state due to the careless mistake of an extension telephone set server by sending a holding tone to a talker at the central office side without necessitating the operation of the extension telephone set server. CONSTITUTION:A voice level monitoring device 150 is comprised of a comparator 180, and an extension nonaudio detector 160 is comprised of a counter 190. When a voice signal is connected to a point A, output appears at the output of a point B only when it is the voltage exceeding a comparison voltage VREF, and the output appears at a point C by counting the number of a CLD (clock) by the counter 190. However, when voice exists, the output of the counter 190 is cleared by the output of the comparator 180, and no output appears, however, the when no voice exists, the output of the counter 190 is outputted without being cleared, and the nonaudio detector 160 detects nonaudio, and sends information with respect to that to a central control unit 140. Thereby, it is possible to prevent the unrequired conversation at the extension telephone side from leaking or the central office side speech from being left at the nonaudio state.

Next, the operation of this embodiment will be explained. First, the extension side telephone operator 100 connects the line circuit 110 to the switch network 1.
30 - During a call with a caller on the office line side via the office line trunk 120, the call between the extension telephone operator 100 and the caller on the office line is terminated after informing the caller on the office line that he/she wishes to hold the call. There will be no sound. As a result, the output of the audio level monitoring device 150 disappears, and after a predetermined time has elapsed, the extension silence detection device 16 that was monitoring the output of the audio level monitoring device 150
0 transfers the hold information to the central controller 140. The central controller 140 connects the hold music sending device 170 to the central office line party via the switch network 130 and the central office line trunk 120 . To release the hold, the voice level monitoring device 150 detects the level on the extension telephone operator's side while the hold tone is being sent, and when the extension telephone operator 100 starts a call to release the hold, the voice level monitoring device 150
outputs an output, and the extension silence detection device 160 uses the output.
transfers the hold release information to the central control device B 140. The central controller 140 disconnects the hold music sending device 170 and connects the line circuit 110 to the switch network 130.
- Resuming the call by reconnecting the office line trunk 120;

Next, the circuit configuration of the above-mentioned voice level monitoring device and extension silence detection device will be explained with reference to FIG. When an audio signal is connected to the 0 point, the comparison voltage V is output at the 0 point.
The output appears only for voltages above 1lfF. At the 0 point, an output appears by counting the number of CLK (clocks) by the counter 190, but if there is audio, the output of the counter 190 is cleared by the output of the comparator 180 and does not appear, but if there is no sound, the output of the counter 190 appears.
The output of 90 is output without being cleared, and the extension silence detector 160 detects silence and sends the information to the central controller 14.
Send to 0. FIG. 4 shows a time chart of signals at each point in the circuit of FIG.
