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 PC 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.
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 Type | PC Display Format (hexadecimal) |
|---|---|
| DEFAULT | 00 and 80 |
| ANSI/CHINA | 01 and 81 |
| ITU | 02, 04, 06-0b, 82, 84, 86-8b, and 7F |
| JAPAN | 03, 05, 83, and 85 |
| UNDEFINED | ff |
Note
The 8th bit of the PC display format is used for the dash delimiter with the exception of UNDEFINED (0xff).
The following are examples for the various network types to 32-bit values.
