ABSTRACT:
A computer Input/Output (I/O) subsystem providing communication and control between a computer and external audio and telephone devices. The external signals include stereo audio input signals, stereo audio output signals for headphones, monaural audio microphone input signal, monaural audio output signal for a speaker, analog telephone lines and ISDN. Data to and from the multiple computer I/O ports and data to and from the multiple external devices is all merged for communication over a single time-domain-multiplexed full-duplex serial bus. The telephone circuit is designed as an option and is either analog or ISDN. When the telephone circuit is installed, the serial bus is automatically reconfigured to accommodate the additional data and control information. The telephone circuit transparently merges serial telephone data and serial audio data. For example, MODEM data I/O can occur simultaneously with audio sample data.
