To all ADI participants,

SSC-2 specifies in section 4.2.17 when describing the MAM contents that
"Each TapeAlert flag occupies one bit (Flag 1 = MSB, Byte 1; Flag 64 = LSB,
Byte 8)".  We should use this same bit ordering when defining our TapeAlert
frame so as to be consistent with what is already done.
