<p>PROBLEM TO BE SOLVED: To disperse the readout sequence of respective connection outputs in the read scheduling of a cell retained in a buffer on an ATM switch. SOLUTION: A counter circuit 1 counts up one by one by a cell read timing signal and the counter value is transmitted to an exchange circuit 5. The exchange circuit 5 inversely exchanges the arrangement of the bits of a counter value shown by a binary number. An output band judgement circuit 6 compares the output value K of the exchange circuit 5 with a value Z which a period setting holding circuit 2 holds. When K>Z, a skip signal is sent to a counter skip circuit 7. When the skip signal is inputted, the counter skip circuit 7 counts up a counter circuit 1 by one and an operation is repeated. A connection selection circuit retrieves a connection band setting holding circuit 3 with a value passing through the output band judgement circuit 6 as an address and outputs a connection number which is held.</p> |
