Abstract:
A communication apparatus that enables to appropriately perform IP filtering even when communication via a network is performed by a user inputting a destination phone number. An IP filter permits or rejects communication on the basis of a set IP address. An input unit inputs a phone number. An acquisition unit acquires an IP address corresponding to the phone number inputted by the input unit from a server connected to the network. A setting unit sets the IP filter so that communication using the IP address acquired by the acquisition unit is permitted.
Abstract:
A method for ensuring reliable transmission of a DCN signal by a gateway is disclosed. When acting as a sending gateway, the gateway packs a DCN signal detected into an IFP packet and sends the IFP packet to the IP side, then, reports a fax end event to a Soft Switch after a designated delay period; and the Soft Switch issues a State Switching Command for switching the two gateways back to voice state after receiving the fax end event. When acting as a receiving gateway, the gateway modulates a DCN signal detected and sends the modulated DCN signal to a receiving facsimile machine; if a switching command issued by a Soft Switch is received during sending the DCN signal, the gateway delays the switching; if the gateway has not received a switching command after the DCN data is sent, the gateway initiatively reports a fax end event.
Abstract:
A communication apparatus including: a requiring section which transmits a requirement for establishing a state in which and the communication apparatus and a first communication apparatus are communicable with each other via an internet line, to the first communication apparatus via the internet line; a communication establishing section which establishes the state; a calling section which transmits a dial signal to an exchanger via the telephone line and calls a to-be-called apparatus, when the communication establishing section has established the state; a notifying section which transmits a notification about calling of the communication apparatus, to the first communication apparatus via the internet line after the calling section has called; a receiving section which receives an acknowledgment signal transmitted via the internet line from the first communication apparatus having received the notification; and a communication controlling section which controls the communication with the to-be-called apparatus via the telephone line.
Abstract:
An image communication apparatus having an Internet facsimile communication device and a G3 facsimile communication device includes a detector for detecting a facsimile function of a communication partner's apparatus during communication by the G3 facsimile communication device, and a controller for performing control of causing the G3 facsimile communication device to disconnect communication in a G3 facsimile mode and shifting to communication by the Internet facsimile communication device, based on the detection of the facsimile function of the communication partner's apparatus by the detector.
Abstract:
Disclosed is an Internet FAX apparatus which, after receiving an Internet address from a certain destination, can communicate with the same destination in later transmission or during communication by connecting to a LAN and switching to an Internet FAX mode requiring no communication charge. An Internet facsimile apparatus on the receiving side transmits its Internet facsimile function and Internet address on an NSF signal in a standard protocol of G3 facsimile transmission and/or transmits its telephone number, Internet facsimile function, and Internet address on TSI and NSS signals in the standard protocol of G3 facsimile communication. The Internet facsimile apparatus registers an Internet facsimile function and Internet address of a partner apparatus as destination data. The Internet facsimile apparatus communicates with the partner apparatus by using the Internet address in the destination data in later transmission or by disconnecting ordinary facsimile mode communication and switching to the Internet FAX mode.
Abstract:
Disclosed herein are systems and methods for allowing a transmitting facsimile device and a receiving facsimile device to select a preferable communications network or other preferred transmission parameters.
Abstract:
An image forming apparatus, a control method, a memory medium, and a program, in which further larger power saving can be accomplished are provided. An N/W interface circuit and a video interface circuit which are constructed so that a communication possible state and a communication impossible state can be independently controlled are provided. Transmission/reception situations of data to/from an external apparatus are monitored and a power supply and a non-power supply of those interfaces are controlled by a control unit, respectively.
Abstract:
IFAX is installed in securities firm A. PC is installed in a customer B and the other IFAX is installed in a branch C. IFAX transmits and receives image data between PC and IFAX via LAN and the Internet by use of e-mail. While, IFAX is connected to PSTN. IFAX transmits and receives facsimile data between G3FAX and IFAX via PSTN. IFAX transmits and receives image data among PC and the other IFAX and G3FAX and transmits the same image data to a host computer installed in a center in reduction in communication costs with respect to the center.
Abstract:
A method and apparatus for interfacing a personal digital assistant (PDA) with a communications appliance is provided. The method comprising a communication station receiving semi-structured data from a personal digital assistant (PDA) in a format native to the PDA, and parsing the semi-structured data to identify a type of the semi-structured data. If the semi-structured data is destination data, sending a job to a destination indicated by the semi-structured data.
Abstract:
An electronic-mail apparatus, comprises an electronic-mail receiver that receives an electronic-mail via a network, a converter that converts the electronic-mail into printable image data, and a facsimile receiver that negotiates with a facsimile sender. The facsimile receiver receives facsimile image data from the facsimile sender via a telephone network. A printer is configured to print the converted image data and the received facsimile image data. The electronic-mail receiver, the converter, the facsimile receiver and the printer are integrated in the electronic-mail apparatus.
