# Create Line Interfaces

Note: To add a line interface, the Tmedia unit must have a TDM module installed.

### To add a line interface

**1. Select "Line Interfaces" from the navigation panel.**

**3. To create a new line interface**:

* Enter a name for the line interface, and set the Line Type (this setting will depend on the installed TDM module)
* Select a local index number for each line. The local indexes for trunks are zero-based values. This means that local index 0 is trunk 1 and local index 1 is trunk 2. Enter a local index number, assigning a different value to each line interface.
* Set all necessary parameters for the line type chosen, such as Line Length, Encoding, and Signal Level.
* Click "Create"

## 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/legacy-releases-toolpack-v2.x/create-line-interfaces.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.
