    摘要： An secured fax adapter apparatus uses a relay circuit to selectively couple a G3 fax to a secured line via a secured telephone unit (STU). The G3 fax can alternatively be coupled to a public switched telephone network (PSTN) via a PSTN port. The secured fax adapter has an enhanced DAA having a controller, a fax communication circuit, a current limited off hook detection circuit, a relay circuit for selectively coupling the external device ports, and a ring generation circuit for producing a square wave for ring generation. In one embodiment, the current-limited off-hook detection circuit uses a symmetrical network of transistors coupled to diodes to limit the current drawn by a load. In another embodiment, the relay circuit has four relays for selectively coupling the G3 fax to the fax communication circuit, the STU to the PSTN, the G3 fax to the PSTN, or the STU to the fax communication circuit. The relay circuit has an additional relay for coupling the off-hook detection circuit to the fax communication circuit.

    摘要： A telephone set incorporated in a facsimile system using two or more telephone numbers called by respective call signals having different patterns, which are stored in a pattern data memory when the call signals are received and detected in a registering mode and with which the pattern of a call signal received when the telephone set is not in the registering mode is compared to determine the telephone number being called. The registering mode is established by an operator-controlled mode setting device. The patterns of the call signals are detected by a pattern detector in the registering mode, and the detected patterns are registered in the pattern data memory, so that the telephone number called by each call signal is determined by a pattern determining device as a result of comparison of the pattern of each call signal with the registered patterns in the pattern data memory. A selective call signal processing device is operated upon reception of a facsimile call signal in a distinctive ringing ON mode also established by the data input device, so that facsimile communication is initiated without distinctive ringing based on the facsimile call signal.

    摘要： Apparatus for use in receiving input signals through order wires; at least one of the input signals is a specific signal including an input control signal indicative of supply of the specific signal to either a telephone set (6) or a facsimile set (15). A processing circuit processes (2) the input signals into an input single signal; an input detecting circuit (3) detects the input control signal in the input single signal; a judging circuit (14) judges whether the input control signal indicates supply of the input single signal to the telephone set, or to the facsimile set and produces an input connection signal; and a connection unit (20) connects the processing circuit to the telephone set and to the facsimile set when the input connection signal indicates the telephone set and the facsimile set, respectively. It is also possible to use the apparatus to transmit output signals produced by the telephone set and the facsimile set through the order wires.

    摘要： A communication apparatus which can carry out a facsimile communication with a calling station and a speech communication with the calling station. The communication apparatus includes, a monitoring block for monitoring received signals, a first determining block for determining, based on a result obtained by the monitoring block, whether or not a first signal transmitted from the calling station is received, a transmission block for transmitting a second signal to the calling station, a first control block for activating the transmission block in a case where the first determining block determines that the first signal is not received within a first time after the communication apparatus becomes capable of communicating to the calling station, a ringing unit for outputting a ringing tone, a second control block for activating the ringing unit when a second time elapses from a time at which the transmission block starts to transmit the second signal, and a third control block for performing the facsimile communication when the first determining block determines that the first signal is received.
