2. Protocol Field Assignments
The MAPOS Version 1 Data Link Layer [1] contains a 16 bit Protocol
field to identify the the encapsulated protocol. The Protocol field
is consistent with the ISO 3309 (HDLC) extension mechanism for
address fields. All protocol numbers MUST be assigned such that the
least significant bit of the most significant octet equals "0", and
the least significant bit of the least significant octet equals "1".
