# Creating an N+1 Group

> **Applies to:** Tmedia 3.0, 3.2, 3.3

Once the N+1 patch panel is created, you must configure an N+1 group and assign each hardware unit to their correct position on the N+1 pacth panel.

**To create an N+1 Group:**

1- Click **N+1** in the navigation panel

![N Plus One 0 A](https://docs.telcobridges.com/w/images/b/bf/N_Plus_One_0_A.png)

2- Click **Create New N+1 Group**

![N Plus One 1 A](https://docs.telcobridges.com/w/images/b/bf/N_Plus_One_1_A.png)

3- Set the correct serial numbers for units that are assigned as Primary and Secondary N+1 Patch panels, as well as the N+1 Backup unit.

* Configure the following:
  * Primary N+1 Patch Panel: N+1 patch panel for the main fiber
  * Secondary N+1 Patch Panel: N+1 patch panel for the APS
  * N+1 Backup Unit: Standby unit
  * Auto switch-back: Select this option to automatically switch TDM and VoIP media back to the original unit when it becomes available. If this option is not selected, then the backkup unit will remain active until it is manually rebooted.
  * Port 0 to 14: Units must be listed as they are physically connected to the N+1 patch panel.
* Click **Create**

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://prosbcdocs.telcobridges.com/tmedia-documentation/configuration/creating-an-n-1-group.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.
