Abstract
In traditional networks, a user provides an authorization to establish a connection for services with an Optical Network Terminal (ONT) and an Optical Line Terminal (OLT). The ONT becomes vulnerable to unauthorized users because the ONT restricts access at an Internet Protocol level. An embodiment of the present invention includes a system that restricts user access to services by causing a ranging fault to disable an ONT from communicating upstream with the OLT in an event the user fails to provide a valid ONT level user authorization. In an event the ONT is in a ranged state and the user fails to provide a valid service level authorization, the system causes a service level fault to restrict the ONT from granting user access to the user to services. Thus, unauthorized users are prevented access to the ONT and increased security is achieved.
