# ONU configuration features ## Presets for ONU The first main feature to start after adding OLT is the [Presets for ONU](/configuration-features/presets.md). This workspace will help you add a list of saved ONU configurations (Presets), allowing you to apply them on unregistered ONUs for [registration](/onu-workspace/onu-registration.md) process or [change](/onu-workspace/onu.md#quick-actions-panel) the configuration of an existing ONU on the specific ONU page to work the way you want. Usually, these settings are done through the terminal manually for each ONU, but in the EasyPON web application, it can be done simply with UI right from the web in seconds. ## Actions for ONU In the EasyPON web application, an [Action](#actions-for-onu)[ for ONU](#actions-for-onu) (Optical Network Unit) could be a specific operation or function that you want to perform on an ONU device in your daily ISP tasks and operations. This could include tasks like provisioning, configuring, or troubleshooting the ONU. Actions can be applied from a specific ONU page. --- # Agent Instructions: 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.
