Abstract
Abstract A user interface simplifies operation of a intelligent facsimile machine (IFAX). A display screen displays a plurality of menus and allows the user to select from the menus. The IFAX can store a plurality of digital cover pages to minimize transmission time for a facsimile cover page. The user may select from a list of stored digital cover pages. The user may also attach a binary data file to a facsimile message and transfer the data to another facsimile machine. The IFAX uses a storage location for storing outgoing facsimile messages. The IFAX periodically check the storage location to determine if more than one facsimile message is to be transmitted to the same location and transmits the facsimile messages in one facsimile telephone call. If the IFAX is coupled to a second IFAX on a network, the two IFAX machines can balance the work load by sending a load transfer request if the number of outgoing facsimile messages exceeds a predetermined threshold level. The IFAX can also route incoming facsimile messages to a variety of destinations such as a floppy disk or other storage device, or an external computer. The IFAX can also relay incoming facsimile messages to another facsimile machine, using a set or relay instructions. The relay instructions may be stored in the IFAX or may be a portion of the incoming facsimile message. The relay instructions may be nested, and the IFAX sends the facsimile message to a second IFAX with instructions for the second IFAX to relay the facsimile message to a third facsimile machine. The IFAX contains security measures to prevent unauthorized relaying.
