ABSTRACT:
A cell dropout preventing system includes a memory for temporarily storing cells which are obtained by dividing transmitting data into cells having a fixed length, an address generating part for generating a read address signal of the memory, a controlling part for controlling the address generating part based on a timing signal received from a line side and for transmitting to the line side the cell read from the memory by the read address signal generated from the address generating part, and a read completion detecting part for outputting a detection signal when it is detected that one cell is read completely from the memory. The controlling part controls the address generating part so that a cell which is the same as a previous cell is read from the memory and transmitted to the line side when no detection signal is received from the read completion detecting part.
