# Logical Connection Creation subflow

# Logical Connection Creation subflow {#ariaid-title1}

The Logical Connection 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 {#logical-connection-creation-subflow__section_kfd_fdk_x5b}

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 {#logical-connection-creation-subflow__section_xbc_vyp_x5b}

The following table lists the input fields in the Logical Connection Creation subflow and their descriptions.
{#logical-connection-creation-subflow__table_w3g_2fm_1vb__entry__3}

| 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 (![Add icon.]()) to add a connection element. | Array.String |
