<p>PURPOSE:To make the configuration of a unit switch for each stage identical by providing a header addition means adding a switching header in a prescribed order before a unit switch of a 1st stage and providing a header rearrangement means before a unit switch after 2nd and succeeding stages. CONSTITUTION:An end batch header conversion circuit 20 is arranged to an input terminal of a unit switch 10 of a 1st stage and a header rearrangement circuit 30 is arranged to an input terminal of 2nd and 3rd stages. The inputted information is subjected to end batch addition of switching headers for all stages by the header addition means 20 and the resulting information is sent to the unit switch 10 of the 1st stage and switched based on the switching header and inputted to the header rearrangement means 30 provided before the unit switch 10 of the 2nd stage and a switching header representing an output terminal of the unit switch 10 of the 2nd stage is added to the head of the information and outputted. Similarly, the replacement is applied to the information at the 3rd and succeeding stages. Thus, the configuration of the unit switch 10 is made identical to each stage.</p> |
