If a device has not communicated within 30 days, an alert will be sent notifying the user that the device has not been used. After 90 days with no communication, the license usage is released, however, the device itself will continue to run in an “Authorization Expired” state until the ID certificate is revoked, which is one year after the last communication. At this point, the product returns to evaluation mode under the terms of the particular product’s evaluation policy.
