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, the legacy terminals communicate with a data frame that conforms to a legacy data frame format and the upgraded terminals communicate with a data frame that conforms to an upgraded data frame format, which is a legacy-compatible extension of the legacy data frame format. The legacy data frame format enables the detection, but not correction, of errors in a data frame and the upgraded data frame format enables the correction of errors in the data frame.
