<p>PURPOSE:To easily cope with the increase of subscribers with use of the cascaded multiplexing circuits by connecting a multiplexing circuit to the output terminal of each input highway, and performing the multiplexed control. CONSTITUTION:A multiplexing circuit 2 is provided at an output terminal of each input highway 1 and performs individually the conflict control at multiplication. In this case, a cell is sent to a multiplexed highway 3 set at the output side via the circuit 2 in the case the cell exists only at the highway 3 which has an input to the circuit 2 or the highway 1 only. In the case both highways 1 and 3 include the cells, the order of cells sent to the highway 3 is controlled based on the control signal received via a control signal line 4. Thus it is possible to easily cope with the increase of subscribers.</p> |
