# Creating an MTP3 Configuration

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

Once you have set up the MTP2 layer of your SS7 system, you must create an MTP3 configuration. [MTP3](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/protocols/mtp3/README.md) provides message routing between signaling points in an SS7 network.

To create an MTP3 configuration:

1- Select **MTP3** from the navigation panel

![Mtp3 0 A](https://docs.telcobridges.com/w/images/9/9b/Mtp3_0_A.png)

2- Configure the new MTP3 service:

* Enter a **name** for the MTP3 configuration
* Make sure the **Enabled** and **SSf Validation** boxes are checked
* Select **SP** as the **signaling point type**
* Click **Create**

![Mtp3 1 A](https://docs.telcobridges.com/w/images/5/5c/Mtp3_1_A.png)

3- Verify that the **"Mtp3Cfg was successfully created"** message appears

![Mtp3 2 A](https://docs.telcobridges.com/w/images/e/ec/Mtp3_2_A.png)

**Path**

```
/configurations/@[configuration_name]/mtp3_stacks/@[mtp3_name]
```

**Parameters (text)**

```
/configurations/@[configuration_name]/mtp3_stacks/@[mtp3_name]
enabled              = true
name                 = "@[mtp3_name]"
signaling_point_type = "SP"

/configurations/@[configuration_name]/mtp3_stacks/@[mtp3_name]/advanced_parameters
ssf_validation             = true
transfer_restrict_required = false

/configurations/@[configuration_name]/mtp3_stacks/@[mtp3_name]/timers
t15_timer = "2 seconds"
t16_timer = "1400 milliseconds"
t18_timer = "11 seconds"
t19_timer = "67 seconds"
t21_timer = "63 seconds"
t26_timer = "12 seconds"
```

**Parameters (json)**

```
{
  "advanced_parameters" : {
    "ssf_validation" : true,
    "transfer_restrict_required" : false
  },
  "enabled" : true,
  "name" : "@[mtp3_name]",
  "signaling_point_type" : "SP",
  "timers" : {
    "t15_timer" : "2 seconds",

# 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-mtp3-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.
