SUMMARY
=======
In conventional Intel bit ordering, the most significant bit (MSB) is numbered 7
and the least significant bit (LSB) is numbered 0:
MSB LSB
7 6 5 4 3 2 1 0
In Systems Network Architecture (SNA), IBM defined the LSB and MSB to be the
opposite of the Intel convention. The MSB is numbered 0 and the LSB is numbered
7:
MSB LSB
0 1 2 3 4 5 6 7
You need to consider the difference in the Intel and IBM conventions when
interpreting SNA Server traces using the IBM SNA Formats Guide (part number:
GA27-3136-10).
