Publication number: 20250048005Abstract: A device for detection of a clipped ringing signal includes a ringing generator, a ringing signal adjusting-and-driving section, and a voltage-detection and clipping-judgment section. The ringing signal adjusting-and-driving section receives a ringing signal from the ringing generator. The ringing signal adjusting-and-driving section also receives a gain adjusting signal. The ringing signal adjusting-and-driving section outputs the ringing signal to a subscriber loop after adjusting the gain thereof according to the gain adjusting signal. The voltage-detection and clipping-judgment section is coupled to the subscriber loop to detect the loop voltage waveform of the subscriber loop, and to determine that the ringing signal is clipped when the loop voltage waveform is discontinuous. When the ringing signal is clipped, the voltage-detection and clipping-judgment section sends the gain adjusting signal to drive the ringing signal adjusting-and-driving section to attenuate the gain of the ringing signal.Type: ApplicationFiled: July 1, 2024Publication date: February 6, 2025Inventor: Tsung-Hsien HSIEH
