摘要:
A method for processing non-standard facilities frames by T.38 gateways, wherein the T.38 gateways includes at least one transmitting gateway and at least one receiving gateway, the transmitting gateway is connected with a transmitting facsimile machine, and the receiving gateway is connected with a receiving facsimile machine. The method includes: a) the transmitting gateway and the receiving gateway determining the types of all received V.21 frames; b) when the receiving gateway or the transmitting gateway receives a non-standard frame NSF, modifying the non-standard frame NSF, so that the corresponding receiving facsimile machine or transmitting facsimile machine is unable to receive a correct NSF frame; c) the receiving gateway encapsulating the modified NSF frame data, or the transmitting gateway modulating the modified NSF frame data and transmitting the modulated frame data. The method modifies the rate negotiation performed with proprietary frames as a negotiation performed with standard frames.

摘要:
A facsimile machine includes an image data generating unit that reads a original and generates image data, an information transmitting and receiving unit that transmits and receive the digital data, a first data generating unit that generates first digital data used for a real-time communication method without using analog data, and a second data generating unit that generates second digital data used for a deemed voice communication method without using analog data.when using the real-time communication method, the first data generating unit generates the first digital data and the information transmitting and receiving unit transmits the first digital data to the destination.When using the deemed voice communication method, the second data generating unit generates the second digital data and the information transmitting and receiving unit transmits the second digital data to the destination.
摘要:
A system comprising a first network gateway coupled to a circuit-switched network, the first network gateway to initiate a tunnel through the circuit-switched network responsive to packetized fax relay data received from a packet-switched network, and a second network gateway couple to the circuit-switched network, the second network gateway to receive packetized fax relay data through a tunnel over the circuit-switched network from the first network gateway.
摘要:
In facsimile-communicating an original when the Internet selection state in an operation unit is set to “automatic selection”, the original is communicated by selecting the e-mail-based Internet for an A4 original size, and the session-based Internet for a B4 or A3 original size. At the same time, the original information is transmitted in accordance with the transmission mode of its own apparatus, the encoding method determined based on the reception capability of a facsimile apparatus at a reception destination, and the receiving-side output original size and resolution.
摘要:
A facsimile capture device is provided that functions in a plurality of operating modes. In a first automatic operating mode, the facsimile device captures received facsimile or “document” data without user intervention, and subsequently transmits the data to a device represented by a capture address. In one embodiment, the data is transmitted to a file management appliance (“FMA”) which utilizes multiple processes and queues to provide document capture and indexing services to a network. In a second manual operating mode, the facsimile device selectively captures and modifies received document data based upon additionally received external input data. The facsimile device is capable transmitting the document data to a plurality of secondary devices utilizing various transmission and encapsulation protocols. In one embodiment, the facsimile device transmits captured document data to indexing and archiving devices according to standard Internet protocols.
摘要:
A color facsimile device capable of transmitting color image information through multiple communication methods, such as G3, G4, T.37, and T.38, which can convert color image information into that represented in appropriate color space for each communication methods.
摘要:
A data communication apparatus includes a communication section that performs pre-communication protocol to exchange a communication function with a communication destination terminal, and transmits data to the communication destination terminal after the pre-communication protocol. A detector detects whether or not the communication destination terminal can perform a short protocol in which at least a communication protocol for line probing is omitted. When the detector detects that the communication destination terminal can perform the short protocol, a controller obtains communication parameters from the communication destination terminal, stores the obtained communication parameters in a memory in association with the communication destination terminal. The stored communication parameters are utilized to perform the short protocol.
摘要:
A data communication apparatus includes a communication section that performs a pre-communication protocol and transmits data to a destination terminal. A memory stores data and communication parameters corresponding to each destination terminal, the communication parameters being utilized to perform communication with the destination terminal. When data corresponding to a destination terminal data is stored in the memory, a controller performs the pre-communication protocol with the destination terminal, using the stored communication parameters corresponding to the destination terminal. When a communication error occurs in a communication with a particular destination terminal having data stored in the memory, a memory controller deletes communication parameters corresponding to the particular destination terminal from the memory.
摘要:
A virtual voice mode facsimile communication unit, comprised of a TCP/UDP/IP control section which controls an IP protocol and a TCP/UDP protocol, a real-time transfer control section which controls a real-time transfer protocol, a voice encoding/decoding section which encodes/decodes a voice signal, a MODEM which modulates/demodulates assuming that a facsimile signal is a voice signal, a T30 control section which controls a T.30 facsimile protocol and a communication image processing section which conducts image processing of communication image data, is provide for real-time facsimile communications with a conventional facsimile apparatus over an IP network in a state kept connected to a LAN via a network I/F.
