Abstract
A transmission device includes a control card and a plurality of IF cards. The control card receives first set time from a host PC and calculates second set time by adding add time corresponding to one cycle of a clock signal that is commonly used by the control card and the IF cards to the first set time. The control card distributes the second set time to each of the IF cards. After each of the IF cards receives the second set time and sets the second set time in an internal timer, when a clock signal is detected, each of the IF cards starts a time measuring operation of the internal timer from the second set time.
