IDLE SUPPRESSION AND SIGNAL THRESHOLD DETERMINATION THEREFOR

摘要

A compression technique is used to suppress the idle or silent portion of bo th stations in a facsimile transmission. Facsimile transmission is a half-duple x protocol resulting in considerable idle time for either the called terminal or the calling terminal. The invention provides a signal level threshold for ea ch station whereby signals above the threshold are allowed to pass through whil e signal levels below threshold are not, resulting in more efficient network bandwidth utilization.
