ABSTRACT:
A communication apparatus is provided which is capable of facsimile communication, voice communication and concurrent voice/facsimile communication. In one version, the apparatus has first and second connecting units for connection to a voice communication terminal (such as a conventional telephone) and a data communication terminal (a facsimile apparatus or the like), respectively. A selector selects between those two connecting units. An analog signal from either the voice communication terminal or the data communication terminal is binarized, the two streams of data (if the apparatus is in concurrent transmission mode) are mixed, and the resulting data stream is converted to an analog signal for transmission. Similarly, an incoming analog signal, if received in the concurrent communication mode, is separated into binary voice and binary non-voice data, which are then separately processed and output as appropriate. Also, it is possible to switch among voice, data, and concurrent voice/data modes.
