<p>PROBLEM TO BE SOLVED: To provide a band changing system of a PVC channel in an ATM communication network capable of changing communicating information in the middle of communication in a system prohibited from delaying. SOLUTION: In the case of changing the band changing system of a PVC channel, the using situation of the channel of a second table, which is managed by a processor 27 and exists in a host memory 28, is set to be released to execute pseudo release of the channel. Next, a first table holding channel information, which is managed by an ATM communication LSI 22 and exists in a shared memory 24, is retrieved to confirm the using state of the channel and in the case of being not in communication, the information is rewritten to new information. In addition, the using situation of the channel of the second table is set to be in connection, the pseudo reconnection of the channel is executed.</p> |
