Abstract: A digital transmitter device to execute a network browser application to access an e-mail account of an e-mail server and retrieve data stored in thereat. The digital transmitter device can scan and send an image to a network address along with the retrieved data.

Abstract: A document is scanned in a scanning device to obtain electronic data. The electronic data represents information on the document. The electronic data is stored to a storage device. An error then occurs either before or after beginning transmission of the data to an e-mail server. The error causes a failure in the communication of the data to the e-mail server. The method of failure detection depends on the type of failure. For a loss of power, the data storage device is examined for the electronic data. If electronic data is found, communication is established with the e-mail server and the electronic data is transmitted to the e-mail server. The data storage device must be a non-volatile data storage device to recover from a loss of power error. For a loss of communication with the server or failure to establish communication with the server, communication is established with the e-mail server and the electronic data is transmitted to the e-mail server.

Abstract: When data communication is performed by using a call control protocol, a data communication apparatus receives a call connection request message from an external apparatus and transmits a response message in reply to the call connection request message. At that time, when the call connection request message is received, it is determined whether a call connection process for communication with another external apparatus differing from the external apparatus is under execution. Transmission of the response message is controlled based on a result of the determination.

Abstract: Facsimile communication is correctly performed even when an echo is generated in a communication line having a delay, by handling an echo signal in such a manner that when an echo of a CFR signal (according to the ITU-T recommendation V.21) transmitted from a receiving communication apparatus is received by the receiving communication apparatus, the echo signal is not recognized as a carrier of a picture signal and training data is not adjusted on the basis of the received echo signal, thereby making it possible to receive a correct short training/picture signal which arrives thereafter. A facsimile communication procedure includes storing training information when long training information is received, detecting success in receiving short training information, detecting high-speed data, setting the stored training information into the modem, and changing the receiving operation in response to detection of short training information and high speed data.

Abstract: A method and apparatus for establishing communication between a sending facsimile machine and a receiving facsimile machine first receives an answer tone message for a specified time. It then is determined if a given joint menu message has been received from the receiving facsimile machine at any time during the specified time.

The alias joint menu message is different from the given joint menu signal and thus, not a true joint menu message that can be used by the sending facsimile machine.

The transmission signal is transformed and provided to an output, where it is subtracted from a composite signal representing a combination of the actual transformed transmission signal and a receive signal. The subtraction yields an isolated receive signal, which is later processed to recover the full receive signal.

Abstract: A half-duplex facsimile modem system according to the present invention may exhibit a shorter startup time relative to conventional systems. The modem system exchanges capabilities information concurrently with the transmission of a conventional answer signal, thus obviating the need for performing a separate capabilities exchange procedure. In addition, the modem system is capable of determining a preferred training sequence duration based upon one or more characteristics of the current channel. The preferred training sequence duration is communicated from the answer modem to the calling modem such that the calling modem can format the training sequence in an appropriate manner. The resultant training sequence has a time duration that is variable in response to, e.g., the signal-to-noise ratio of the instant channel. These techniques can result in a significant reduction in the startup latency typically associated with conventional half-duplex facsimile modem systems.

Abstract: Various kinds of modem control information is stored for each destination, the modem is operated based on stored various kinds of control information to shorten a communication pre-protocol and transmit data when execution is carried out. Also, when a short previous-procedure does not normally proceed, communication is shifted to a second communication procedure whose speed is low so as to continue communication after a lapse of a predetermined period of time. When abnormality occurs after executing the short previous-procedure, various kinds of control information stored in memory means are erased and up-dated. Therefore, time for communication preprotocol is shortened, and a mounted short previous-procedure function appropriately operates even when a communication error rate is high or a line characteristic is changed.

Abstract: A facsimile machine comprises a fax/modem section for communicating signals with a communication line in order to sending and receiving a fax and a computer unit for outputting AT commands such as a DCS reception command for requesting reception of a DCS (Digital Command Signal) and a TCF reception command for requesting reception of a TCF (Training Check Field) to the fax/modem section. The fax/modem section immediately changes into a TCF reception state for receiving a TCF if the fax/modem section received a DCS. In the TCF reception state, the fax/modem section receives the TCF sent via the communication line and temporarily stores the TCF in a TCF buffer, regardless of whether or not the fax/modem section has already received the TCF reception command from the computer unit. The fax/modem section sends the TCF in the TCF buffer to the computer unit when the fax/modem section received the TCF reception command from the computer unit.

Abstract: A relay device associated with each end point modem in a data communication network provides a system for transporting data over a communication channel employing voice compression. Each relay device exchanges relevant parameter information with its associated modem and with each other in order to negotiate compatible data transfer conditions.

Supported data rates, modulation type and encoding information is also exchanged. The invention provides a system for full duplex transmission of data over modems while saving on bandwidth because of voice compression techniques.

To support the tandem configuration, full duplex communication may be established between the two base stations. Full duplex communication may be realized by incorporating an echo canceler in the base station, or by utilizing both BFSK channels of the V.21 fax system for communication. The tandem configuration may also be supported by advanced flag synchronization, wherein a second base station will immediately start sending preamble flags to a first base station after a message is transmitted from the first base station to the second base station. The first base station may then synchronize its receiver for immediate receipt of the return message from the second base station.
