By using the Telecommunications Network Inventory function catalog, you can access the functions that help you to automate the network inventory's Design and Assign process.
* **[Allocate Free Number function](https://servicenow-prod.fluidtopics.net/PuuJW2JxrgTywUnIAXcLeg)**   
  The Allocate Free Number function enables you to assign free numbers from the Telecommunications Network Inventory number record. You use this function to allocate a quantity of numbers from a specified range to add against the configuration item (CI) in a number element.
* **[Create CI From Template function](https://servicenow-prod.fluidtopics.net/LL~zoSfWRCAzN6vgmL65sw)**   
  The TNI Create CI From Template function enables you to create the inventory instance in the designated site or equipment holder in the Telecommunications Network Inventory application. This occurs when you instantiate an inventory with the inventory template. You can automatically create the inventory when you instantiate the network inventory design and assign process.
* **[Cascade Update function](https://servicenow-prod.fluidtopics.net/W97Jp~xw_w8ibvUCGhteRw)**   
  The Cascade Update function enables you to update a configuration item (CI) attribute in the Telecommunications Network Inventory application and cascade the change in all related CIs. You can use this function to automatically cascade the field values in related CIs when you use Workflow Studio.
* **[Create and Assign Range/Single Number function](https://servicenow-prod.fluidtopics.net/gjw3tsjWew5ep25EHTlyEA)**   
  The Create and Assign Range/Single Number function enables you to create the inventory number records for a number range when you process the network inventory workflow.
* **[Create Logical Interface function](https://servicenow-prod.fluidtopics.net/2nX46P9be0B6QeJSId3OKA)**   
  The Create Logical Interface function enables you to create logical interfaces in the Telecommunications Network Inventory application.
* **[Create Logical Connection function](https://servicenow-prod.fluidtopics.net/DgjILFpYXEo~QjRh9KK9ZQ)**   
  The Create Logical Connection function enables you to create a logical connection record in the Telecommunications Network Inventory application based on the input (interfaces) that you receive when you instantiate an inventory.
* **[Create Physical Connection function](https://servicenow-prod.fluidtopics.net/7ieQdTkzr9dlznGE7OWaYw)**   
  The Create Physical Connection function enables you to create a physical connection record in the Telecommunications Network Inventory application based on the input that you receive when you instantiate an inventory.
* **[Create IP subnetwork function](https://servicenow-prod.fluidtopics.net/A5Gcil3U92nQAk1e9LyYJQ)**   
* **[CIDR to IP range function](https://servicenow-prod.fluidtopics.net/2zW3eRjGoF3fvMBCMr30Ww)**   
  Classless Inter-Domain Range (CIDR) to IP range flow action enables you to create a set of IP addresses using the Classless Inter-Domain Range (CIDR) using Telecommunications Network Inventory application based on the input that you receive when you instantiate an inventory.
* **[Get Interface Summary function](https://servicenow-prod.fluidtopics.net/eBCtV3e6ngo0JOIWyFGiJw)**   
  The Get Interface Summary function enables you to retrieve all the network interface records that are associated with the input. You can use this function to automatically get the details of the available interface, connected interface, and the physical connection of the equipment in the Telecommunications Network Inventory application when you use Workflow Studio.
* **[Lookup Next Hub function](https://servicenow-prod.fluidtopics.net/ZzBLvcSLnnYarEgYkudhZQ)**   
  The Lookup Next Hub function enables you to take the network interface record as input and return the details of the related physical connection record. You can automatically get the details of the physical connection and interconnected ports of the equipment in the Telecommunications Network Inventory application when you use the Workflow Studio application.
* **[Path Search function](https://servicenow-prod.fluidtopics.net/Y0XR1w7cHadZ_06YQjXcOQ)**   
  The Path Search function enables you to execute the path computation function between the starting and ending sites in the Telecommunications Network Inventory application. You can use this function for the path computation when you process the network inventory design and assign.
