# Design your GPON Broadband Service

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 Inventory** > **Inventory Models**, create your inventory models, and define their relationships.

    To learn more, see [Manually creating and reviewing your network asset instances](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-network-inventory/telecommunications-network-inventory/creating-telecommunications-network-inventory.md).

2.  Navigate to **Telecom Network Inventory** > **Network 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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-network-inventory/telecommunications-network-inventory/preparing-inv-templates-network-asset-generation.md).


Install the Telecommunications Network Inventory Advanced and Core demo data.

Role required: sn\_ni\_core.inventory\_admin, sn\_ni\_core.inventory\_agent

## Procedure

1.  Navigate to **Workspaces** > **Network Inventory Workspace**.

2.  Select the list icon \(\[Omitted image "ni-workspace-list-icon.png"\] Alt text: List icon.\), and then go to **Changes** > **All**.

3.  Select the **New** button.

4.  Select **GPON Broadband Service** > **Next**.

5.  On the record producer form, you can update the fields.

    The fields of the record producer form are auto-populated. This demonstration displays how to create configuration items \(CIs\) to show the design and assign of a GPON broadband service. To learn more about the fields, see [Change request and change task forms](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-network-inventory/telecommunications-network-inventory/change_request_forms.md).

6.  Select **Save**.

    The Change \(Design & Assign\) flow is triggered and a change request is created. Depending on the given inputs, change tasks are automatically created and other related tabs appear. To learn more, see [Change request related tabs](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-network-inventory/telecommunications-network-inventory/tni-change-request-related-tabs.md).

7.  Open and review each change task record.

    On the Task Attributes form, fill in the fields. For a description of the field values, see [Change request and change task forms](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-network-inventory/telecommunications-network-inventory/change_request_forms.md).

8.  Select **Submit**.

    The **Details** tab is updated.

9.  On the **Affected CIs** related tab, see all the configuration items that are impacted due to this change task.

10. Select **Save**.
