Classification: CPC H | IPC H

Claim 11:
12. The communication system according to claim 11, wherein the inspection circuit comprises:
a verification circuit coupled to the physical layer circuit to receive the current data unit, and coupled to the coding layer circuit to receive the received data identification value, wherein the verification circuit uses the current data unit and the received data identification value to calculate current received data verification information; and
a comparison circuit coupled to the physical layer circuit to receive the transmitted data verification information, and coupled to the verification circuit to receive the current received data verification information, wherein the comparison circuit compares the transmitted data verification information with the current received data verification information, and when the current received data verification information does not match the transmitted data verification information, the comparison circuit generates the error flag to the physical layer circuit.
