Voice communication terminal for internet communication, voice communication terminal for internet communication and PSTN communication

摘要

The invention Internet communication voice communication terminal, the internet communication and the PSTN relates to a communication combine voice communication terminal, in particular, the present invention is the handset or ear / transmission using the analog voice signal to pulse code modulation (PCM) scheme which is input through the headset converted to a digital bit stream, or the digital signal to the inverse PCM codec is converted into an analog signal for transmission to the handset or ear / headset for and; It is interconnected and PCM codec unit, DSP unit for performing signal processing by a digital operation and; Which it is interconnected with a DSP unit, applying the data to a specified path by integrating the management data supplied from the digital operation processing on the data and the computer main unit and the DSP, and a CPU for controlling each component to perform a given operation; It is interconnected with the CPU and an interface unit for interfacing to adjust the format and the operation timing of the data exchanged between the CPU and the computer main body; And it is connected to the CPU, and include, depending on alarm signals from a CPU to an alarm output from the speaker to the warning sound. Therefore, according to the present invention it has an effect that can be supported by maintaining a secure high-quality sound and uniform quality of the Internet to perform high-quality communication.
