A Point Code (PC) is an address in the SS7 network. It can reference a SSP, STP or SCP. Depending on the SS7 variants, point code may have different Length.
The peer SS7 SSP address is referred as Destination Point Code or DPC.<br\> The local SS7 SSP address is referred as Originating Point code or OPC.<br\> We also sometimes use the term Adjacent Point Code (APC) to identify an entity connected directly to the unit with SS7 links.<br\>
<br\>The Point codes can be represented in different formats, depending on the SS7 variants:
- For ITU variants, the Point Code length is 14 bits, in a format 3.8.3
- For Japanese variants, the Point Code length is 16 bits, in a format 7.4.5
- For ANSI and Chinese variants, the Point Code length is 24 bits, in a format 8.8.8
Some regions use different formats than the dotted notation. It can either be decimal or hexadecimal.
For example:
| Variant | Dotted Notation | Decimal | Hexadecimal |
|---|---|---|---|
| ITU | 2.14.1 | 4209 | 1071 |
| ITU | 7.250.7 | 16343 | 3FD7 |
| ANSI | 251.3.1 | 16450305 | FB0301 |
You can use the tool Point Code Converter (PCC), from LogMeTT, to convert between the different formats.
