Flow of ATM Cells

The flow of ATM cells is as follows:

1.Cells sent over lines are received by the line cards.

2.The line cards generate switching information from the VPI, VCI, and PT in the cell header.

3.The switch/CPU card outputs cells to the line cards corresponding to the destination lines.

4.A line card that receives a cell converts the VPI, VCI, and PT in the cell header.

5.Cells are sent to the destination lines.

As an ATM switch, the switch/CPU card time-division multiplexes ATM cells from the four line cards, uses AFs (address filters) to sort the input ATM cells according to the destinations in their headers, then sends the ATM cells to the line cards. In addition, the switch/CPU card is equipped with a CPU and has an interface with MAT or NMS to perform hardware control, path connection control, and protocol control.
