<p>PROBLEM TO BE SOLVED: To flexibly set/change connection order by changing the logical port number of a cell signal into the physical port number of a cell switch in the input port of the cell switch through the use of a converting table. SOLUTION: The header adding part of an IF part 100 adds the logical port number to an inputted ATM cell signal 10 and outputs the ATM cell signal 11. A routing table part 204 inputs VP number/VC number signals transmitted from the header detection changing parts 201 of respective ports and successively selects and outputs them. The cell switch 203 detects the logical port number of the inputted ATM cell signal and outputs the ATM cell signal to the position of the applying physical port number at an output side. The header removing part 202 of IF 102 at the output side in an SW part 101 removes the part of the physical port number being an in-device header and transmits it to an output part 16 as the first ATM cell signal.</p> |
