ABSTRACT:
A method and apparatus for logging or identifying each page of a facsimile transmission or reception by a facsimile machine with a facsimile access controller is disclosed. The method involves several steps which include monitoring the transmission or reception of data by the facsimile machine for a resolution signal and end-of-line signals in the data, determining the number of lines which will be on a page based upon the resolution signal, counting the number of the end-of-line signals transmitted, detecting an end-of-page signal, and logging a transmission or reception of a page when the total count of the end-of-line signals indicates that a page has been transmitted or the end-of-page signal is detected. The apparatus includes a monitor coupled to the signal line from a facsimile machine for monitoring data on the signal line during facsimile transmissions or receptions. A converter is coupled to the monitor for converting the data from the signal line. A microprocessor is coupled to the converter for detecting a resolution signal and end-of-line signals in the data, determining the number of lines which will be on a page based upon the resolution signal, counting the number of the end-of-line signals transmitted in the data, and detecting the end-of-page signal. A memory is coupled to the microprocessor for storing operations to be executed by the microprocessor. A control device is coupled to the microprocessor for logging each page of a facsimile transmission or reception when the count of end-of-line signals indicates a page has been transmitted or the end-of-page signal is detected.
