Description: Each bit of this value set to '1' indicates a specific fault
    in the Media Gateway processor.

    Octets are numbered in the order in which they appear in the PDU.
    Bits are numbered from the most-significant leftmost bit in the
    octet (bit 0) to the least-significant rightmost bit (bit 7).

    Cajun numbering continues across octets, so that octet 1 bit 0 is
    called bit 8 in the Cajun scheme.  That number is also shown below,
    with the octet value for each single bit set.
