An asynchronous transfer mode protocol

摘要

The protocol involves transferring at least one status byte from an asynchronous transfer mode (ATM) layer device to a physical layer device, followed by transferring a physical identification byte from the asynchronous transfer mode (ATM) layer device to the physical layer device after the step of transferring of the at least one status byte. Subsequently it requires transferring an ATM data cell from the asynchronous transfer mode (ATM) layer device to the physical Layer device after the step of transferring the physical identification byte wherein an assertion of control signal identifies a beginning of the ATM data cell. The protocol further entails asserting a transmit enable signal which is output from the asynchronous transfer node (ATM) layer device to the physical layer device to initiate the transferring of the ATM data cell.
