An ITU-T specification, published in 1999, for binary file transfer (BFT) that permits compliant facsimile devices to send any image file type (e.g., .eps, .pcx, and .bmp) in the form of an editable file that retains its specific file attributes. T.434 offers facsimile the additional advantages of increased throughput and reduced document storage requirements through data compression.T.434 works with computer-based facsimile systems and Group IV fax machines, and supports the linking of fax systems to photocopiers, scanners, e-mail gateways, and PCs. See also facsimile, Group IV, and throughput.
