FecContainer.fec - decoded

\

• Byte 1 = number of FECs in containers
    ○ SingleFEC and MultiFEC each count as one
• Byte 2 - 9 1st SingleFEC /MultiFEC identifier
    ○ SingleFEC: 000000AB0000001102 
        § Byte: 10 - 13: FEC
    ○ MultiFEC: 000000XX0000001107 
        § Byte: 10-13 : ffffffff -> for MultiFec
• Byte 5: length of that SingleFEC (always AB)/MultiFEC
• Byte 14 + 28: VIN, VCNR and TIME
• More complicated now:
    ○ SingleFEC: 000000000000000000
        § followed by SIGNATURE
    ○ MultiFEC: 
        § Byte 43 number of FECs in MultiFEC
        § FEC List in big endian -> byte length depending on number of fecs
        § Followed by SIGNATURE
        § Followed by number of Fecs
        § Followed by Fecs in little endian
• Add to finish SingleFEC/MultiFEC
    ○ 0100000003000000FF000000

Normally you only have SingleFEC (ODIS) or MultiFEC (Factory), but this can be mixed…
