摘要:
Whether a facsimile transmission tone is within a call is detected before routing the call from a switch of a telephone network to a first telephone line. When the facsimile transmission tone is detected, whether an incoming facsimile transmission transmitted by the call is permitted to be routed to the first telephone line is determined based at least partially on restriction information. Routing of the call from the switch to the first telephone line is denied when the incoming facsimile transmission is not permitted to be routed to the first telephone line.

An image input/output system is used to input information for specifying the transmission source of data and a period of time during which the data should be received as search conditions for specifying the data that should be received. On the basis of the input conditions, the reception history of the data received via a network or a public network is read. The reception history is searched to determine whether the data that should be received has already been received. On the basis of the determination result, when the data that should be received has not been received, the fact that the data has not been received is reported.

Disclosed is a communication apparatus connected to an analog public line, which can be actualized at low costs and can save its space. This communication apparatus includes a first communication means connected to a telephone line, for performing communications, and a connecting means for connecting a second communication means connected to the telephone line via the first communication means and thus performing communications. In this communication apparatus, the first communication means has a first switch means for connecting the telephone line to the first communication means or the second communication means, a first route means for connecting the second communication means to the telephone line via the first switch means, a second route means for connecting the second communication means directly to the telephone line, a second switch means for connecting the second communication means to the first route means or the second route means, a first hook detecting means connected to the first route means, and a second hook detecting means connected between the telephone line on the second route means and the second switch means.

An image communication apparatus comprises a connection unit for connecting an external terminal, an image communication unit for conducting image communication, a switching unit for selectively connecting a line to said connection unit and said image communication unit, a first detection unit for detecting a calling signal from said line, a second detection unit for detecting a signal relating to the image communication, a third detection unit for detecting a signal relating to data communication, and a control unit for controlling said switching unit in response to the detection by said first, second and third detection units.
摘要:
A device and a method for directing incoming calls from a single input telephone line to either a facsimile machine, a data modem, or a telephone is provided. The device and method provide for "isolating" both a facsimile machine and a data modem until after a predetermined delay period, thus preventing them to answer the call. If a person or answering machine has not answered the call within the delay period, an off-hook condition is simulated to the input telephone line, thus "answering" the call. The signal on the input telephone line is then detected. If the signal includes a DTMF digit, various functions are performed including resetting internal variables. If a facsimile handshake signal is detected, the facsimile machine is rung with a ring simulator. The facsimile machine can then read the incoming handshake signal and proceed in a conventional fashion. If, however, neither of these two signals are detected, and a telephone answering device has not answered the call, the data modem port is rung with the ring simulator. The data modem will then begin receiving the transmitted signal in a conventional fashion. If the call is answered during the delay period provided by the invention, and the transmission is a facsimile handshake signal, the call is automatically transferred to the waiting facsimile machine.
摘要:
A visual telephone apparatus of the present invention is capable of deciding whether the apparatus of the other party of communication is a normal telephone apparatus or facsimile equipment by the operator who hears the data received from a connected communication medium or automatically by analysis of the procedure of controlling the communication with the apparatus of the other party, and transmitting the data obtained by photographing a subject in accordance with the communication specification corresponding to the apparatus decided, as well as receiving the data from the apparatus of the other party in accordance with the communication specification corresponding to the apparatus decided and displaying the data on a display unit. The apparatus is also capable of visual telephone communication with a visual telephone set and facsimile communication with facsimile terminal equipment.
摘要:
A communication system is disclosed having a portable radio called receiver and a communication apparatus for calling this receiver. The portable radio called receiver includes a display and a tone generating circuit. The communication apparatus includes a determination circuit, a control circuit, a voice signal recording device, a facsimile device, a memory, and a data processing circuit. The determination circuit determines whether a signal entered through a telephone line is a facsimile signal or a voice signal. The memory stores display data indicating the reception of an image signal, display data indicating the reception of a voice signal, and telephone number data of the portable radio called receiver. The control circuit is responsive to the output of the determination circuit to select one of the plurality of display data stored in the memory. The data processing circuit modulates the calling number of the portable radio called receiver and the selected display data and transmits the same on the telephone line. With such a structure, the display of the portable radio called receiver can display whether the received signal of the communication apparatus is an image signal or a voice signal.

A communication system comprises a plurality of speech communication terminals each having apparatus for inputting data representing a station. A call is issued in accordance with the data from the communication terminal, and the system receives call data representing a station which responds to the call. The data received by the system is compared with the data input from the speech communication terminal and display units of the speech communication units are controlled in accordance with the comparison result.
摘要:
A communication apparatus includes a facsimile system for performing data communication, a plurality of telephone sets for performing speech communication; and a control unit for controlling the facsimile system. Each telephone set includes a display unit for displaying a state of data communication. The control unit selectively sends information associated with the state of the facsimile system to the telephone sets to cause the display units to display the state of the facsimile system.
