Abstract: A method of establishing communication between an optical line terminal and an optical network unit within an optical access network includes receiving a signal indication from an optical transceiver of an optical line terminal. The signal indication includes: (i) a loss-of-signal indication indicating non-receipt of an upstream optical signal from the optical network unit; or (ii) a signal-received indication indicating receipt of the upstream optical signal from the optical network unit. The method includes determining whether the signal indication includes the loss-of-signal indication. When the signal indication includes the loss-of-signal indication, the method includes instructing the optical transceiver to cease signal transmission from the optical transceiver to the optical network unit.

Abstract: A method includes receiving user data packets from customer premises equipment (CPE) in communication with a network terminal over a communication link and enabling a network terminal-side loopback mode to establish a closed traffic test loop across the communication link between the network terminal and the CPE. The received user data packets indicate that a CPE-side loopback mode is enabled. The method also includes injecting a number of data bits into the closed traffic test loop until a saturation threshold of the communication link is satisfied, and when the number of data bits injected into the closed traffic test loop satisfies the saturation threshold, determining a packet error-rate of the number of data bits circulating in the closed traffic test loop. After determining the packet error-rate, the method also includes removing the closed traffic test loop across the communication link between the network terminal and the CPE.

Abstract: A system and method for optimizing various vehicle safety systems, such as airbags and seat belt load tensioning limiters, for a particular occupant of a vehicle seat, such as the vehicle driver or passenger, based on the weight of the occupant and the fore-aft position of the seat. The method senses the mass of the occupant and the position of the seat and classifies the combination of the mass and position. The method then determines the optimized setting of the safety systems for that combination classification, and automatically sets the safety systems to that setting. The method can also determine the optimized setting of the safety systems based on whether the occupant is wearing a seat belt.

Abstract: A signal distribution system includes global positioning system receivers in communication with optical line terminals and a system manager. Each global positioning system receiver receives a signal from a corresponding global positioning system satellite. Each optical line terminal includes a management card and a line card. The management card receives a signal from a corresponding global positioning system receiver. Each line card receives a signal from each management card and determines a signal drift and a phase precision for each signal. The system manager receives a failure communication for a global positioning system signal from a line card when the signal drift of the global positioning system signal is above a threshold signal drift or the phase precision of the signal is below a threshold phase precision. The system manager identifies a failure location of the signal within the system based on one or more received failure communications.
