The function list data and settings are displayed at the computing device when a remote setup routine is executed, and a user can identify the functions and function setting options of the connected facsimile, and set function settings by an input device. The computing device sends the desired function settings to the facsimile device, and the facsimile device changes its function settings according to those received.

Abstract: This invention is related to a communication terminal device and communication method for communicating with another terminal device in a full duplex manner or a half duplex manner depending upon a function of the another terminal device. A new recommendation V.8 of the International Telecommunication Union was established as a data transmission method for use in telephone exchange networks. This V.8 is suitable for use with telephone sets and data modems and not only facsimile devices. Devices which are in accordance with this new recommendation V.8 will be put on the market in the near future. Presently, half-duplex facsimile devices also exist thus functions which cope with half-duplex communication are also necessary. This invention, while being a terminal device basically adapted for the recommendation V.8, proposes a terminal device that can communicate with previously used half-duplex terminal devices, and a terminal device using that communication method.

The algorithm is hierarchically arranged having three major routines or portions: tone detection, signal recognition and situation recognition. The tone detection portion of the algorithm measures the power at each of a predetermined number of frequencies of interest.

Specifically, power within a voice filter band is compared with power at other predetermined frequencies and a decision is made based on this information. Furthermore, another improved aspect is that data for an entire Epoch is accumulated and stored in a buffer prior to processing as a group.

Abstract: Tone signal (34a) having a reference frequency (f) which is produced by the tone signal generation device (34) at the transmitter part is transmitted, via transmitter device (32), antenna (31), aerial line, antenna (32), to the reception sector (12). Then, the received tone signal (12a) is compared by the frequency correction circuit (A) with the preset reference signal (f), and according to a result of the comparison, a frequency produced by the reception sector (12) is corrected. That is, an error produced between the transmission frequency by the transmitter (32) and the reception frequency by the receiver (12) is apparently canceled. Thereby facsimile data can be transmitted so correctly to the receiver part so that the facsimile communication with use of radio SSB system can be successfully applied, although there may be an error between the transmitter frequency and the receiver frequency.

The fourth step is transmitting a non-standard facilities set-up signal to the receiving station after the non-standard facilities signal is received. The fifth step is transmitting the stored image information from the transmitting station to the receiving station.

Abstract: A facsimile device transmits image data from a calling station to a facsimile device at a called station over a transmission line. The facsimile device has an image reader for reading image data to be transmitted, and a driver including a motor for actuating the image reader to read the image data. When a TCF signal is transmitted from the calling station to the called station to check the condition of the transmission line, a controller energizes the motor, which results in electrical noise being generated, corrupting the TCF signal. The controller then controls a transmission rate at which the image data is to be transmitted depending on the level of electrical noise in the TCF signal, that is detected at the called station. Since the transmission rate is established depending on the level of electrical noise, communication or decoding errors are reduced during the transmission of the image data.

Abstract: In an image communication system capable of performing communication at a plurality of transmission speeds, a transmission-side apparatus transmits a line condition check signal (a TCF signal of the CCITT facsimile recommendation T30, or the like) for determining a transmission speed prior to communication of image data. A reception-side apparatus determines an optimal transmission speed on the basis of a reception state of the line condition check signal (a square error accumulation value, an error count result, or the like in an equalizer of a reception-side modem), and informs the determined transmission speed or a fall-up or fall-down instruction of a transmission speed to a necessary step to the transmission-side apparatus. The optimal transmission speed according to a line condition can be set within a very short period of time.

The system receives information from a sending facsimile machine, and determines if conversion needs to be made. If conversion needs to be made, the device sends the proper handshaking signals to the sending facsimile machine.
