<p>A methodology for enabling terminals that perform forward error correction to interoperate with terminals that perform automatic-repeat-request is disclosed. This is advantageous because it does not require that all of the terminals be upgraded at once, which is an all-to-common fact of many migration paths. In accordance with the illustrative embodiment of the present invention, legacy terminals communicate with data frames that conforms to a legacy data frame format (300) and upgraded terminals communicate with data frames that conforms to an upgraded data frame format (302), which is a legacy-compatible extension of the legacy data frame format (300). The legacy data frame format (300) enables the detection, but not correction, of errors in a data frame (302) and the upgraded data frame format (302) enables the correction of errors in the data frame.</p> |
