Abstract
A method of transmitting a cell between the ATM layer and the physical layer is provided for the ATM matching system, which includes the physical layer divided into a specified number of uniform physical device groups multiplexly polled by the ATM layer. The method comprises the steps of multiplexly polling the physical device groups by the ATM layer, transmitting an enable signal to the polled device upon receipt of a state signal from the physical layer, transmitting the cell to the physical layer, checking the multiplexed polling of the ATM layer by the physical layer, writing a physical port number into the cell with transmitting a state signal to the ATM layer upon receipt of the multiplexed polling, and transmitting the cell to the ATM layer upon receipt of an enable signal from the ATM layer.
