<p>PROBLEM TO BE SOLVED: To set a trigger state in a fluctuation absorbing device. SOLUTION: The value of the sequence number + 1 of a reception packet is applied from a UUI code holding part 3 to a reception counter 1. When a call is turned into a set state by call setting 115, a counter trigger generating part 11 generates counter trigger. In receiving the counter trigger, the reception counter 1 starts counting from the sequence number received from the UUI code holding part 3. Thus, the reception counter 1 can synchronize with the sequence number of a reception packet to be received the next and following time.</p> |
