TELEFACSIMILE MODULE CONNECTABLE TO TELEFACSIMILE MACHINES FOR TRANSMITTING DATA IN STANDARD OR HIGH SPEED MODES

摘要

A telefacsimile module (600) is connected between a conventional telefacsimile machine (host telefacsimile unit) (500) and a phone line interface (18). The module receives conventional fax output from its host unit and retransmits them to a destination telefacsimile machine in one of standard and high speed modes depending on the compatibility of the destination telefacsimile. The standard mode communication employs a conventional fax format for both text and graphics. The high speed mode distinguishes text from graphics and performs optical character recognition on suspected character information.
