  • Publication number: 20090328190
    Abstract: Flaws in information security infest modern software, and pervasive computing has made network systems vulnerable. Information security is constantly endangered by errors in protocol implementations. Testing a protocol implementation for errors directly from a network where a device implementing the protocol resides limits the coverage of protocols tested. In contrast, testing protocols from an access network that internetworks a customer premises with one or more service networks greatly expands the coverage of protocols tested. Accordingly, a method and corresponding apparatus are provided to test from the access network, testing both service network devices and customer premises devices, and the protocols implemented on those devices.

  • Publication number: 20090313476
    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.

  • Publication number: 20090310615
    Abstract: Example embodiments of the present invention help extend service provider visibility to all premises equipment (CPE) devices that are ranged with an Optical Line Terminal (OLT) by associating an Optical Network Terminal (ONT) within each device (CPE-ONT), such as a personal computer (PC), set-top box (STB), broadband home router (BHR), or analog telephone adapter (ATA). Therefore, each CPE device is managed independently via the CPE-ONT integrated with it. This allows each CPE device to terminate only optical signals supporting communications supported by the CPE device. Further, each CPE device has access to the entire GPON bandwidth, thereby increasing performance and eliminating bottlenecks caused by electrical communications over 10/100/1000 BaseT interfaces.

  • Publication number: 20090285106
    Abstract: A problem of collecting data unnecessarily in an Internet Protocol Television (IPTV) network is, in part, caused by a centralized approach to data collection, whereby data is collected for logical channels, even if not currently streaming to an end node. A method or corresponding apparatus of fault detection according to an example embodiment of the present invention provides for detecting and reporting faults specific to a logical IPTV channel in an IPTV network for logical channels actively streaming to an end user device, such as in response to a “join” request. One or more nodes supporting a logical IPTV channel provide fault indicators, which may be reported to another node or end user. Node(s) in the IPTV network may aggregate and process multiple fault indicators from across a network, thereby enabling diagnosis of specific errors in the IPTV network. Through the use of the method or apparatus, network resources are conserved.

  • Publication number: 20090263139
    Abstract: An Optical Network Terminal (ONT) has a fixed number of voice ports. A system employing an example embodiment of the invention increases the number of voice ports without changing hardware in the ONT by employing an Analog Terminal Adaptor (ATA) expander and configuring the ATA expander through use of a Session Initiation Protocol (SIP) and other network resources already available in a network with which the ONT is associated. The ATA expander is configured to be compatible with the ONT and, thus the ONT can increase voice services without hardware changes to support growing demands by customers for access to voice services via increasing number of Customer Premises Equipment (CPE).

  • Publication number: 20090074423
    Abstract: Separating Passive Optical Network (PON) functions in different mechanical devices, such as optical to electrical conversion of the PON protocol, allows installation of an optical termination device at an exterior of an installation premises and installation of a user interface device performing PON functions inside the installation premises. Various embodiments allow service providers first to install an optical device outside the premises and, later, to install an electrical device, optionally by a customer. This eliminates a service provider from entering the installation premises and enables the customer to complete installation in the interior of the installation premises. Further, more robust, hardened components may be used in the more-permanently installed exterior device, while less-expensive, lower-quality components may be used in the easily-replaceable indoor device, thus reducing cost.

  • Publication number: 20090042536
    Abstract: Common techniques for processing cellular service uses a signal cellular tower, but these techniques are limited to the capacity of the single cellular tower. In contrast, a system employing an example embodiment of the invention increases ability to process cellular service by using an access point access network using resident wireless devices, referred to as a femtocell. A system supports communications of a resident and roaming device while employing the access point access network, based on database information, to support soft handoff between adjacent femtocells or from femtocell to cell tower and vice-versa. As a result, the system enables the resident and roaming devices to have seamless transitions between the cellular access network and the access point access network. Thus, the access point access network supplements cellular access networks and can provide cellular service regardless of the capacity of the cellular tower.

  • Publication number: 20090024725
    Abstract: Common techniques for processing software updates have Optical Network Terminal (ONT) and Broadband Home Router (BHR) managers to manage the ONTs and BHRs respectively from separate remote locations in a network. In contrast, a system employing ‘an example’ embodiment of the invention may receive network traffic for an ONT and BHR (“components”) via a single management channel. The system parses signals (e.g., software updates) and processes the management signals with a processor in a first component (e.g., ONT). The system converts a remaining software update to a format compatible with a management channel between the components to forward to the second component (e.g., BHR) for processing. In this way, the system may update multiple components using a single management channel. Thus, software updates or other management procedures can be performed using a single management channel with improved efficiency.

  • Publication number: 20090015204
    Abstract: A method and apparatus provide for managing operations associated with a backup power source at a network terminal. A network terminal includes a battery port that, when enabled, is configured to monitor status of a battery coupled to the battery port and provide a status indicator for the battery. The network terminal also includes an interface with selectable states. A control circuit detects the state of the interface and presence of a battery at the battery port. In response to the interface being in a given state in an absence of a battery coupled to the battery port, the control circuit causes the battery port to enter or remain in a disabled state. The battery port substantially maintains the disabled state over reset, loss of power and reconfiguration of the network terminal. If the battery port detects the presence of a battery, it responds by entering an enabled state to monitor the status of the battery and provide battery status indicators.
