ABSTRACT:
A facsimile machine having a semiconductor DAA provided in a line I/F part performing facsimile data communication with a network includes a tone signal reception part in the form of a semiconductor device. The tone signal reception part is provided in the semiconductor DAA and receives a tone signal with high impedance through a path different from a path for receiving the facsimile data. The tone signal is supplied from the network or a downstream device.
