# Creating an SCCP GTT Association

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

After you create an [SCCP](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/protocols/sccp/README.md) [SSN](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/sub-system-number/README.md), you must create a new SCCP **Global Title Translation Association**.

**SCCP GTT Association** A GTT association defines a particular [Global Title](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/concepts/global-title/README.md) format and associated fields. It is assumed that all [global titles](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/concepts/global-title/README.md) included in this association have specific translation needs and therefore can be served by a single translation function set.

You can create multiple [**GTT**](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/protocols/gtt/README.md) **associations**. This allows, for example, you to have a separate "Translation Table" for different [Numbering Plan](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/numbering-plan/README.md), E.164 vs E.212.

The **GTT Association** is the association between:

* Inbound [SCCP Network(s)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/sccp-network/README.md)
* A set of filtering rules on [GTI](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/format-type/README.md),[TT](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/translation-type/README.md),[NAI](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/nature-of-address-indicator/README.md),[NP](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/numbering-plan/README.md),[ES](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/encoding-scheme/README.md) values
* A [Global Title Translation](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/protocols/gtt/README.md) table

**Filtering Rules** Inbound [SCCP](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/protocols/sccp/README.md) messages that matches all filter following criteria will hit the associated "Translation Table"

* [GT Indicator](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/format-type/README.md)
* [Translation Type (TT)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/translation-type/README.md)
* [Nature of Address Indicator (NAI)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/nature-of-address-indicator/README.md)
* [Numbering Plan (NP)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/numbering-plan/README.md)
* [Encoding Scheme (ES)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/encoding-scheme/README.md)

**Creating an SCCP GTT Association**

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

![Create SCCP Stack 0](https://docs.telcobridges.com/w/images/f/fa/Create_SCCP_Stack_0.png)

2- Click **Create New Sccp GTT Association** from the SCCP stack configuration window

![Create SCCP GTT 0](https://docs.telcobridges.com/w/images/e/ed/Create_SCCP_GTT_0.png)

3- Configure the new SCCP GTT association:

* Enter a [Name](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/name/README.md) for the new GTT association
* Select a [Protocol Variant](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/protocol-type/README.md)
* Select an [SCCP Network](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/sccp-network/README.md) to bind to this GTT Association
* Select a [Format Type (GTI)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/format-type/README.md)

![Create SCCP GTT 1](https://docs.telcobridges.com/w/images/b/b6/Create_SCCP_GTT_1.png)

4- Depending on [Format Type](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/format-type/README.md), select if you want to filter on GT following parameters. Below example shows the applicable fields for Format Type = "Type\_4":

* [Translation Type (TT)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/translation-type/README.md)
* [Nature of Address Indicator (NAI)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/nature-of-address-indicator/README.md)
* [Numbering Plan (NP)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/numbering-plan/README.md)
* [Encoding Scheme (ES)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/encoding-scheme/README.md)

5- Click **Create**

6- Verify that the **"SccpGTTAsso 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-an-sccp-gtt-association.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.
