发明名称 PCM-based data transmission system and voice/data communication switching method
摘要 A transmitting terminal creates a data PCM stream in which data is recognized as a PCM stream by placing a prefixed idle code string before data to transmit and a postfixed idle code string after the data to transmit. By switching between a voice PCM stream and a data PCM stream, PCM steam is transmitted to a receiving terminal. The receiving terminal, when detecting the prefixed idle code string from a received PCM stream, receive the data from the transmitting terminal until detecting the postfixed idle code string.
