<P>PROBLEM TO BE SOLVED: To reduce the influence of a crosstalk on transmission signals to be respectively transmitted to two transmission lines. <P>SOLUTION: A master unit control part 1 prohibits the signal transmission (packet transmission) of a second transmission processing part 2 during a period when a first transmission processing part 11 performs signal transmission (time-division multiplex transmission), and permits the signal transmission of the second transmission processing part 2 after the signal transmission by the first transmission processing part 11 is terminated. Consequently, transmission signals are not simultaneously transmitted to a slave unit connection line LB and a dwelling unit line LA. Thus, the interference of the transmission signals does not occur, thereby to reduce the influence of a crosstalk on the transmission signals to be respectively transmitted to two transmission lines (the slave unit connection line LB and the dwelling unit line LA). <P>COPYRIGHT: (C)2012,JPO&INPIT |
