Click Create New Feature, then Publishable Feature.
Enter a FeatureName. Names cannot be longer than 32 characters and can contain only letters, number, dashes, and underscores.
Enter a unique Feature Code. Consider carefully when creating a feature code. It is used throughout the subscriber provisioning system to identify the network feature and cannot be changed once you create the feature.
Decide whether you want embedded-client device users to have the ability to enable and disable the network feature. If you select the Device users can enable/disable this feature check box, select the Default User State:
On: The network feature is enabled when it is pushed to the embedded-client device.
Off (default): The network feature is disabled when it is pushed to the embedded-client device.
If you allow embedded-client device users to enable/disable the network feature, select a UX Reference Code. (See Network Feature Properties for details about this property.)
Optionally, enter a Description. A good description will explain what the feature is intended to do.
Changes are saved automatically as you make them. However, device behavior is not enforced by network features until you test and publish the network feature.
