Some Examples

For the purposes of the AAL5 checksum, individual bytes are presumed to be transmitted with the most significant bit first.

For a forty eight byte ATM cell which forms a single AAL5 block. If the forty data bytes are all zeros then the CRC value in the last four bytes is 0x86, 0x4D, 0x7F, 0x99.

If the forty bytes of data are all 0xffs then the CRC value in the last four bytes is 0xC5, 0x5E, 0x45, 0x7A.

If the forty bytes of data are sequential numbers beginning 0x01 and ending 0x28 then the CRC value in the last four bytes is 0xBF, 0x67, 0x1E, 0xD0.
