Example 2: Locally Defined and Binary Syntax DSP
The AFI in this example, as in those previous, is 39. Once again, Table 2-1 (wrong)
shows that an AFI value of 39 identifies the IDI format as ISO DCC and the DSP syntax
type as binary.
Table 3-2
on page 3-11 shows that the ISO DCC format, as defined by ISO 3166,
identifies the domain (the IDI) as the data country code (in this case, 999), and specifies
a three-digit IDI length. In this example, lets assume that 999 is the code for country
“X”.
The DSP is the rest of the address. Table 3-3
on page 3-12 shows that the binary DSP
syntax for the ISO DCC format can have a maximum of 14 octets; this example has the
maximum length. The meaning of each DSP value in this example is determined by the
addressing authority for country X, and are as follows:
The same address, represented in the nonstandard format used by the
addressing authority for country X, might be as follows:
39.999.0100000000.FF00.08008E0002E3.01
