ABSTRACT:
A telephone communication system for transmitting and receiving both voice signals and digital data signals, with no significant distortion to the voice signals and with substantially higher digital data rates than previously could be obtained in comparable systems. The voice signals are digitized, data compressed, and time-division multiplexed with the digital data signals, to produce a composite digital signal that can be transmitted over conventional telephone lines. The system can be selectively configured in a conventional telephone operating mode, in which the system transmits and receives merely the analog voice signals and all of its various digital circuitry elements are bypassed. The system is automatically configured in this conventional telephone operating mode whenever a significant failure in any of its individual units is detected.
