Title:
FACSIMILE COMMUNICATION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPS62152265
Kind Code:
A
Abstract:
PURPOSE:To improve the reliability of the noise resistance and the transmission control protocol by holding the communication control information of a calling station at the training pattern signal to train the modulating demodulating device of a called station and sending it to the called station. CONSTITUTION:Facsimile data received by a radio equipment 50 are demodulated by a modulating demodulating device 18 and accommodated at one sub-scanning line unit through an encoding decoder 22 to a line buffer 24. The transmitted facsimile data are successively read from an original by the raster scanning operation at the photoelectric transducer of a reading part 30, converted to a binarization signal and accommodated at one sub-scanning line unit to a line buffer 24. This is successively read from the line buffer 24 to the encoding decoder 22, and transmitted from the radio equipment 50 through the encoding decoder 22, the modulating demodulating device 18 and an interface part 10. The function and action of respective parts in these equipment are incorporated and controlled by a system control part 28.
