US 4,837,812 A · Dual connection mode equipped communication control apparatus

Abstract

A facsimile machine including a data processing system for processing data to be transmitted and received data according to a predetermined manner, which system typically comprises a MODEM, a buffer and a CODEC. The facsimile machine includes two or more interface units dedicated for performing a wire communication function for communicating image data in a wire communication mode using a telephone network and a radio communication function for communicating image data in a radio or wireless communication mode using radio waves. The radio/wire switchable facsimile machine includes a switch which switchingly establishes the wire mode or the radio mode. In one embodiment, the switch is manually operated. In a second embodiment the switch automatically establishes either one of the wire and radio modes in accordance with the current status of a predetermined signal, typically an off-hook signal, which indicates whether the handset of a telephone unit is hooked or unhooked or whether the microphone of a radio set is hooked or unhooked.
