# Logical Connection Creation subflow

The Logical Connection Creation subflow enables you to create a logical connection record in the Telecommunications Network Inventory application. The record is 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|
