Design and assign your Gigabyte Passive Optical Network (GPON) broadband service in the Telecommunications Network Inventory application. The GPON Broadband Service change model enables you to create multiple change tasks so that you can fulfill an order request for a GPON broadband service.

## Before you begin

Before you can establish a GPON Broadband Service change request and complete the related change tasks, your inventory catalog and template managers must complete the following setup:

1. Navigate to Telecom Network InventoryInventory Models, create your inventory models, and define their relationships.

   To learn more, see [Manually creating and reviewing your network asset instances](https://www.servicenow.com/docs/u2zonx3biqyodig3Sq2RPw "A key function in the network inventory workspace is to manually create your network assets and a digital model of your network in the Telecommunications Network Inventory application. With this information, you can provision new services, modify existing services, maintain the network, and plan the forecast for your network growth.").
2. Navigate to Telecom Network InventoryNetwork Inventory Templates, create the inventory templates for your equipment, and establish the template relationships.

   To learn more, see [Create inventory template for network asset instantiation](https://www.servicenow.com/docs/KtDpAhf3tS6yaGKsz9_woQ "As an inventory template manager, you create templates using functions you access from the Lists view in the Network Inventory Workspace. These templates contain the detailed business guidance rules so that you can properly configure your equipment. During this process, you also specify the relationships between each inventory template.").
