Abstract
PURPOSE:To reduce ineffective reservations caused by ineffective calls by making early cutting of residual calls possible in a data switching network of a virtual circuit system, by implementing and sending a residual call cut signal based on residual call information. CONSTITUTION:When a cutting request signal is issued from terminal equipment A, a bucket switching device PS1 transfers the cutting request signal to a bucket switching device PS2, but, when a cutting response signal is not received, the bucket switching device PS1 plants call discriminating information stored in areas A2-A4 in a main memory MM in a residual call area A5. In the bucket switching device PS1, the residual call area A5 is scanned at a fixed cycle, and, when it is detected that the residual call information is planted, a residual call cut signal is implemented and sent to the bucket switching device PS2. In such a way, the bucket switching device PS1 sends the residual call cut signal at a fixed cycle until the residual call is cut, and introduces the residual call to be cut whenever the transmitting path is repaired.
