# Example of infrastructure

A BBO is a 1-Wire to Ethernet bridge.

An example infrastructure using BBO units may look as shown below:

![](/files/TyeFBAdVRwtxtq0xmmu6)

The measurements are read using the 1-Wire connections with the sensors and/or interfaces.

Then they are sent in XML format via a POST at port 80. The server needs to acknowledge the received POST by sending a POSTBack reply confirming the reception. The server can also send commands to the gateway, such as to change the transmission intervals for sensors.

Note that the server can only do this immediately after the gateway has sent its POST to the server, so changing a parameter may take some time before it is implemented on the gateway side.

ICU Scandinavia offers the BBO family elements described in detail in [BBO gateways](/bbo-gateway-installation-manual/bbo-gateways.md).

## 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/bbo-gateway-installation-manual/introduction/example-of-infrastructure.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.
