# Creating M2UA Links

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

After you create an [M2UA](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/protocols/sigtran-m2ua/README.md) cluster, you must create M2UA links for your system.

An M2UA link is always bound to an [MTP2](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/protocols/mtp2/README.md) link, and can be seen a way of extending MTP2 functionality.

To create an M2UA link:

1- Click **M2UA** in the navigation panel

![Create M2ua 0](https://docs.telcobridges.com/w/images/8/88/Create_M2ua_0.png)

2- Select an M2UA SAP

![Select M2uaSap 0](https://docs.telcobridges.com/w/images/8/8e/Select_M2uaSap_0.png)

3- Select an M2UA Cluster

![Select M2uaCluster 0](https://docs.telcobridges.com/w/images/7/7b/Select_M2uaCluster_0.png)

4- Click **Create New M2ua Link** in the M2UA cluster configuration window:

![Create M2UA Link 0](https://docs.telcobridges.com/w/images/5/5d/Create_M2UA_Link_0.png)

5- Configure the new M2UA link:

* Enter a **name** for the link
* **IMPORTANT!**
  * **For a system on a signaling gateway**: Select an **MTP2 link**
  * **For a system on a media gateway controller**: Select **NONE**
* Select a **protocol type** (same as MTP2)
* Select an **interface ID type**
* Enter an appropriate **interface ID** (must be unique to each link)
* Click **Create**

![Create M2UA Link 1](https://docs.telcobridges.com/w/images/6/6f/Create_M2UA_Link_1.png)

6- Verify that the **"M2ua Link was successfully created"** message appears

# 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-m2ua-links.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.
