NSAP Addressing
OSI/AS Configuration and Management Manual—424119-001
3-16
Example 2: Locally Defined and Binary Syntax DSP
The AFI in this example is 49. Table 3-1 on page 3-10 shows that an AFI value of 49
identifies the IDI format as locally defined and the DSP syntax type as binary.
Table 3-2
on page 3-11 shows that a locally defined format has a null IDI length.
The DSP is the rest of the address. Table 3-3
on page 3-12 shows that the binary DSP
syntax for a locally defined format can have a maximum of 15 octets; this example has
the maximum length.
The meanings of the DSP values in this example are determined by a local addressing
authority, Network Address Committee “Y,” and are as follows:
Figure 3-5. NSAP Address Example 2
This position...
Means (According to
Committee Y)...
And Has This Value in This
Example...
8 binary octets Unknown meaning 0102030405060708
12 hex. digits IEEE MAC address of the
local system
08008E0002E3
2 hex. digits NSAP selector on local end
system
01
Note. This example, showing an embedded MAC address in the NSAP address, does not
imply that the MAC address is used by the existing Network Layer protocols, nor does it imply
that the practice is recommended. However, such embedding is often used.
