# Logical Connection Creation subflow

The Logical Connection Creation subflow enables you to create a logical connection record in the Telecommunications Network Inventory application based on the input that you receive when you instantiate an inventory.

You can use the Logical Connection subflow to create a logical connection on your network interface cards.

This subflow also creates the connection elements and associates them to the logical connection.

If you enter a network interface, equipment, physical connection, logical connection, or managed function as a connection element, the Logical Connection Creation subflow creates the corresponding connection element.

## Roles and availability

Users with the admin role can add a subflow to a flow and define the configuration details of the flow. This Workflow Studio subflow is available in the Telecommunications Network Inventory application so that you can perform inventory-related data operations.

## Input fields

The following table lists the input fields in the Logical Connection Creation subflow and their descriptions.

|Field Name|Description|Data Type|
|----------|-----------|---------|
|Interface A|Starting network interface where this logical connection is configured.|Reference.Network Interface|
|Interface Z|Ending network interface where this logical connection is configured.|Reference.Network Interface|
|Bandwidth|Bandwidth of the logical connection.|Reference.Bandwidth|
|Connection Type|Type of connection. This field information updates the product model that is associated with the physical connection.|Reference.Logical Connection Model|
|Connection elements|Connection elements that are added for the logical connections. Select the add icon \(\[Omitted image "add-icon-1.png"\] Alt text: Add icon.\) to add a connection element.|Array.String|

To learn more about the variable data types, see [Flow Designer input and output data variables](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/build-workflows/action-inputs-outputs.md).
