<p>PURPOSE:To reduce the abort rate of information due to overflow of a buffer memory by revising the direction of passing priority direction in a switch element in the transmission timing of a cell. CONSTITUTION:The exchange consists of a switch element network 1 comprising switch blocks 31-34 and a buffer memory 2 and the buffer memory 2 is provided for input channels #0-#3. Then a controller 32 revises periodically the passing priority direction of the information in the switch element in the cell transmission timing being the timing of information transmission start stored and processed as cell in the buffer memory 2 to apply switching control. Since the line with priority is changed in the cell transmission timing in this way, the sequential storage of the information to one buffer memory 2 only is avoided. Thus, the increase in the abort rate of the information due to overflow of the buffer memory 2 is avoided.</p> |
