What is proposed is a method of checksum modification for signaling a specific error of a plurality of specific errors of an apparatus, the method comprising a step of receiving a data frame comprising a data packet and a checksum for the data packet, a step of modifying the checksum according to one of a plurality of error signaling patterns each describing a different specific error, a step of replacing the checksum by the modified checksum (320') and a step of outputting the data frame (300') comprising the data packet (310) and the modified checksum (320').
