Create Logical Connection with template subflow
Summarize
Summary of Create Logical Connection with template subflow
The Create Logical Connection with template subflow in the Telecommunications Network Inventory (TNI) application allows you to create a logical connection record based on an inventory template. This subflow automates the creation of logical connections on network interface cards and also generates and associates the relevant connection elements such as network interfaces, equipment, physical connections, logical connections, or managed functions.

This capability is important for ServiceNow customers managing telecommunications network inventories, enabling streamlined and accurate instantiation of logical connections that reflect real network configurations.
Key Features
- Template-driven logical connection creation: Uses inventory templates to instantiate logical connections efficiently.
- Automatic connection element creation: Creates necessary connection elements and associates them to the logical connection based on input elements like interfaces or physical connections.
- Input flexibility: Accepts various inputs including starting and ending network interfaces, bandwidth values, connection type, logical connection templates, connection elements, and position data.
- Output details: Provides glide records of the created logical connection and its relationships with starting and ending network interfaces.
- Access control: Available for users with the admin role to configure and add this subflow within Workflow Studio.
Input Parameters
The subflow requires detailed inputs such as:
- Interface A and Interface Z: References to the starting and ending network interfaces.
- Change Task: Reference to the change task associated with the logical connection instantiation.
- Bandwidth A and Bandwidth Z: Bandwidth specifications at each interface end.
- Connection Type: Defines the logical connection model and updates the associated physical connection product model.
- Logical Connection Template: Inventory template reference for the logical connection.
- Connection Elements: An array of connection elements to add, which can be network interfaces, physical connections, or other relevant components.
- Position, End Interface Names: Additional details to specify the logical connection’s placement and interface names.
Output
The subflow outputs include:
- Logical Connection: A glide record representing the created logical connection.
- CI Relationship with Interface A: The configuration item relationship with the starting network interface.
- CI Relationship with Interface Z: The configuration item relationship with the ending network interface.
Practical Use for ServiceNow Customers
This subflow empowers ServiceNow customers to automate the creation and association of logical connections within their telecommunications network inventory, ensuring consistency and reducing manual configuration errors. It integrates seamlessly with other TNI subflows, supporting comprehensive network design and management workflows. Administrators can include this subflow in their flow designs to efficiently instantiate logical connections during change tasks or inventory updates.
The Create Logical Connection with template subflow enables you to create a logical connection record from an inventory template in the Telecommunications Network Inventory application. The logical connection record is created based on the input that you receive when you instantiate an inventory using an inventory template.
You can use the Create Logical Connection with template subflow to create a logical connection from an inventory template 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.
