A communication system comprising a called receiver and a communication apparatus

摘要

The communication system comprises a portable radio called receiver (21, Fig. 2) and a communication apparatus (1) for calling the receiver. The receiver comprises a display (27) and a tone generating circuit (25). The communication apparatus (1) comprises a determination circuit (4), a control circuit (5), a voice signal recording device (in 6), a facsimile device (8), a memory (9), and a data processing circuit (10). The determination circuit (4) makes the determination as to whether the signal entered through the telephone line (2) is a facsimile signal or a voice signal. The memory (9) stores the display data indicating the reception of an image signal, the display data indicating the reception of a voice signal, and telephone number data of the portable radio called receiver. The control circuit (5) is responsive to the output of the determination circuit to select one out of the plurality of display data stored in the memory (9). The data processing circuit (10) modulates the calling number of the receiver and the display data from the control circuit (5) and transmits the same on the telephone line (2). With such a structure, the display of the receiver can display whether the received signal of the communication apparatus is an image signal or a voice signal.
