摘要： The invention concerns an ATM exchange, and is directed in particular to the provision of a cell bandwidth control apparatus for performing bandwidth control for ATM cells sent from the ATM exchange onto the line side. The cell bandwidth control apparatus includes forced empty cell inserting means for forcibly inserting empty cells in a highway connected to an ATM switch. The forced empty cell inserting means inserts forced empty cells in an outgoing highway leading from the ATM switch to a line adapter and thereby limits the line bandwidth of the outgoing highway to within the bandwidth of the line accommodated in the line adapter.

摘要： A method and system including ATM switching equipment provided for switching between a working channel and a protection channel in an ATM network. The method and system include the following processes: In each cell for transmission providing an indication of whether the cell belongs connection currently in a working state via a working channel; cells are duplicated on each connection basis; the duplicated cells are transmitted simultaneously on both a working channel and a protection channel; and valid cells are selected from received cells according to the indication in each cell indicating whether the relevant connection is currently in a working state.
