ABSTRACT:
A CRC calculating unit calculates a DCS code for a DA field to a DATA field and an FCS code for the DA field to a DCS field. A DCS checking unit outputs a DCS check result with a calculated DCS code and a DCS code in the DCS field to a terminal operating unit. An FCS checking unit outputs an FCS check result with a calculated FCS code and an FCS code in the FCS field to an FCS converting unit. The FCS checking unit determines whether to forward through the frame or to forward the frame by storing the calculated FCS code in the FCS field based on the FCS check result. The terminal operating unit determines a processing mode based on the DCS check result.
