# B3 configuration

The S2 radio network must be defined in B3 system. In B3 an S2 Gateway type is used to handle the communication with the S2 Node Server service and its S2 radio network.

If a migration from B2 to B3 is done a migration tool and conversion tool are used to convert database and most of the S2 radio network parameters are moved to B3 system so there are only few settings that shall be updated.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.boomerang3.com/s2-node-supervisor-administrator-manual/b3_configuration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
