# Creating a TCAP Stack

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

After the SCCP layer of the SS7 system is created, you must create the [TCAP](https://prosbcdocs.telcobridges.com/telecom-references/ss7-and-signalling/tcap) layer.

The TCAP layer uses transport services provided by SCCP to implement transaction capabilities application services. TCAP defines the end-to-end protocol between TCAP users, and these users may be located in a SS7 network or in another network supporting TCAP protocol.

To create a TCAP stack:

1- Click **TCAP** from the navigation panel

![Create TCAP Stack 0](https://docs.telcobridges.com/w/images/f/ff/Create_TCAP_Stack_0.png)

2- Configure the new TCAP stack:

* Enter a **name** for the TCAP stack
* Select a **primary adapter**
* Select a **secondary adapter**
* Click **Create**

![Create TCAP Stack 1](https://docs.telcobridges.com/w/images/f/ff/Create_TCAP_Stack_1.png)

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

![Create TCAP Stack 2](https://docs.telcobridges.com/w/images/a/a7/Create_TCAP_Stack_2.png)

**Path**

```
/configurations/@[configuration_name]/tcap_stacks/@[tcap_stack]
```

**Parameters (text)**

```
/configurations/@[configuration_name]/tcap_stacks/@[tcap_stack]
enabled         = true
name            = "@[tcap_stack]"
primary_unit    = "NONE"
return_on_error = true
secondary_unit  = "NONE"
```

**Parameters (json)**

```
{
  "enabled" : true,
  "name" : "@[tcap_stack]",
  "primary_unit" : "NONE",
  "return_on_error" : true,
  "secondary_unit" : "NONE"
}
```

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://prosbcdocs.telcobridges.com/tmedia-documentation/configuration/web-portal-3-3/protocol-stack/sccp-tcap/creating-a-tcap-stack.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
