Overview

Some configurable variables require that you convert point codes into a 32-bit integer.

As shown in the following figure, the Most Significant Bit (MSB) represents the Point Code (PC) display format, while the remaining 24 bits contain the actual PC values. The point code display format is based on the network SS7 Variant.

Point Code 32-bit Definition

 

For ITU Point Code values, the third byte is always 00, because only the first 14 bits are used. For Japan Point Code values, the third byte is always 00, because only the first 16 bits are used.

Point Code Display Formats

The following table shows the supported network types and their respective PC Display Formats.

For more information about PC Display Formats, see the appropriate chapter in the latest version of the User Application Protocol Reference.

Network Type Supported PC Display Formats

Network TypePC Display Format (hexadecimal)
DEFAULT00 and 80
ANSI/CHINA01 and 81
ITU02, 04, 06-0b, 82, 84, 86-8b, and 7F
JAPAN03, 05, 83, and 85
UNDEFINEDff
Note

The 8th bit of the PC display format is used for the dash delimiter with the exception of UNDEFINED (0xff).

Examples

The following are examples for the various network types to 32-bit values.

Use the Point Code Converter

The DSC Web UI provides point code conversion tool to assist you with any other point code conversion.

The point code listed in the Point Code Converter are as follows:

  • 8.8.8 : ANSI or CHINA
  • ff-ff and 5.4.7 : JAPAN options (TTC and NTT)
  • all other formats listed are 14-bit and decimal ITU-based point codes

Start

  1. From the DSC Web UI, click IP Networking.   
  2. Click IP Utilities.
  3. Click Point Code Converter.
  4. Select the required input and output format, and click Convert.
