Table 3-22 Octet Field Functions
Octet Function
Octet 3 Octet 3 represents the total number of Octet 3.X fields required for the
specific information element, including the Octet 3 field itself.
Octet 3.1 Octet 3.1 is used to hold Numbering Plan Identification (NPI) and Type of
Network (TON) values. The octet contains eight bits numbered from 1 to 8
and from right to left, so that Bit 1 is rightmost and Bit 8 is leftmost.
The bits contain binary values representing the following functions:
Bits 1-4 = NPI
Bits 5-7 = TON
Bit 8 is always set to 1 when Octet 3.1 is used and populated.
Note The Numbering Plan Identification (NPI) and Type of Network
(TON) fields appear in the Add ISDN Information Elements dialog box
The standard NPI values are:
For an NPI setting of Unknown, the standard integer value is 0
and the standard binary value is 0.
For an NPI setting of ISDN/Public, the standard integer value is
1 and the standard binary value is 0001.
For an NPI setting of Private, the standard integer value is 9 and
the standard binary value is 1001.
The standard TON values are:
For a TON setting of unknown, the standard integer value is 0
and the standard binary value is 0.
For a TON setting of International, the standard integer value is
1 and the standard binary value is 0001.
For a TON setting of National, the standard integer value is 2 and
the standard binary value is 0010.
For a TON setting of Network, the standard integer value is 3 and
the standard binary value is 0011.
For a TON setting of Local, the standard integer value is 4 and
the standard binary value is 0100.
