ABSTRACT:
A data transmission apparatus includes a facsimile section for performing data transmission, at least one multifunction telephone set terminal for performing speech communication, a switching circuit for switching the facsimile section and the multifunction telephone set terminal, and a microcomputer for detecting whether transmission data is set in the facsimile section. The switching circuit switches a transmission line from the multifunction telephone set terminal to the facsimile section when the microcomputer detects that the transmission data is stored in the facsimile section while the multifunction telephone set terminal is engaged with the transmission line.
