REASON: The CLIR interrogation result informs the user only if the service is provided to her. With the introduction of the second temporary mode, this information is no longer sufficient. The user can no longer derive from the provisioning of the service whether her number is shown to the called user or not. CONSEQUENCE OF NON-ACCEPTANCE: The user gets only information about the provisioning of the service, but no information whether the number will be shown to the called user or not.
