Abstract: A facsimile interface apparatus (12) is connected between facsimile terminals (10, 24) communicating via a satellite (16). The interface apparatus converts a conventional facsimile signal (66, 68) to a signal (70, 72, 74) suitable for transmission to the satellite (16). However, the interface apparatus and the satellite may incur a long delay such that the calling facsimile terminal (10) repeats a transmitted signal while the response to that signal is being received over the satellite (16). To overcome this problem, the facsimile interface apparatus (12) connected to the calling terminal (10) sends, after a period t1, a holding signal (90) to the calling terminal (10), to prevent the calling terminal from repeating the transmitted signal (66, 68). After a further period t2, the interface apparatus (12) sends a command repeat signal (93) to the calling terminal (10), so that the transmitted signal (66, 68) is repeated if the called terminal (24) has not transmitted a response.

Abstract: A method and apparatus for facsimile communication uses subaddress messages sent from a sending facsimile terminal to control how a facsimile image transmission is to be handled, e.g., routed and/or translated, by a receiving facsimile terminal. The invention may be employed through the use of an adapter which is designed to work with existing facsimile terminals which are incapable of generating subaddress messages. The invention, when employed with 10-key facsimile machines which cannot generate by the keys thereof proper subaddress delimiting symbols, automatically transforms non-permitted transmission symbols generated by the key to permitted transmission symbols.

Abstract: A facsimile machine stores log information pertaining to facsimile transmission and reception in a facsimile RAM. To output a facsimile management report, log information items are read one by one from the RAM. It is then determined whether the read out log information meets a specific condition. Only log information which does not meet the specific condition is stored in a printer RAM and then printed by a printer. Thus, by taking a condition of log information not needed by the operator and inputting it as the specific condition, for example, log information not desired to be printed can be left out of the printing process.

Abstract: In transmitting enciphered data, to enable an ECM communication, whether a cipher communication is performed or not can be decided according to an available memory capacity. To perform the cipher communication, whether the available capacity of a RAM 4 is sufficient for one frame or not is determined.

When the available capacity X.sub.0 of the RAM 4 is smaller than the memory capacity X necessary for the cipher communication according to the ECM communications method, it is determined that the cipher communication is impossible, and the communications mode is changed to the normal transmission according to the G3 communication.

Abstract: As image data is received by the facsimile machine, it is stored in the form of plural lines. A line which contains black pixels more than a predetermined number is taken as a drawing line (image-carrying line or effective line). All the image data lines are scanned from the top to the bottom to find a top image-carrying line or top effective line and a bottom image-carrying line or bottom effective line and the number of the lines from the top effective line to the bottom effective line is calculated as the number of the effective lines of sending sheet. If the number of the effective lines of the sending sheet exceeds the number of recording lines of a recording sheet, the image data is reduced with a reduction ratio which is determined by the number of the recording lines and the number of the effective lines.

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.
