# Create a SCCP userpart

This step is used to initialize the userpart parameters of the SCCP layer

### Description of parameters

General explanation of the configuration parameters:

* The **Handle SCCP network** parameter specifies the handle of the SCCP network
* The **Unique identifier SCCP Userpart** parameter specifies the unique ID of the SCCP Userpart for a [SS7](https://tmediadocs.telcobridges.com/telecom-references/ss7-and-signalling/ss7) system

***

* The **Message priority** parameter specifies the priority of messages. Allowable values are as follows:

| SCCP Message Priority | Description     |
| --------------------- | --------------- |
| Highest               |                 |
| 0                     | Same as highest |
| 1                     |                 |
| 2                     |                 |
| 3                     | Same as lowest  |
| Lowest                |                 |

***

* The **Connection mode** parameter specifies the different modes of connection for a SCCP userpart. Allowable values include:

| SCCP connection mode | Description                                                                                                                                                                    |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| TCAP                 | SCCP userpart is used in conjunction with an above local TCAP layer and cannot be controlled by the host application but the host application will receive ALARM notifications |
| Host TCAP            | SCCP userpart is used as a standalone and communicates with remote TCAP layer (host application)                                                                               |

***

* The **Subsystem number** parameter specifies a subsystem number for this userpart. Allowable values are from 1 to 255. See the table for ' SCCP SSN value to identify SCCP user' in Toolpack:Create a SCCP route.
* The **Number backup point code** parameter specifies the number of backup point code entries in the Backup Point Code Entries and the Priority Backup Point Code Entries arrays.
* The **Array of backup point code entries** parameter specifies the list of backup point code for this Userpart. This parameter is reconfigurable.
* The **Array of priority of backup point code entries** parameter specifies the list of priority of each backup point code for this Userpart. Allowable values are from 0 to 255.

**Note:** Zero being the lowest priority.

***

* The number concerned point code parameter specifies the number of concerned point code entries in the 'Concerned Point Code Entries' array
* The array of concerned point code entries parameter (specifies the list of concerned point code for this Userpart

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://tmediadocs.telcobridges.com/other-pages/protocol-stacks-ss7/create-a-sccp-userpart.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.
