  • Idle suppression and signal threshold determination therefor
    Patent number: 5878119
    Abstract: A compression technique is used to suppress the idle or silent portion of both stations in a facsimile transmission. Facsimile transmission is a half-duplex protocol resulting in considerable idle time for either the called terminal or the calling terminal. The invention provides a signal level threshold for each station whereby signals above the threshold are allowed to pass through while signal levels below threshold are not, resulting in more efficient network bandwidth utilization.
