  • Patent number: 9231838
    Abstract: In one aspect, the present invention addresses Layer-3 (L3) connection monitoring between two “multi-attached” host nodes that are interconnected via an intervening communication network having a known network topology. The present invention provides the two-fold benefit of rapid connection failure detection and failure location determination. In one or more embodiments, the present invention “pinpoints” the failure location, improving the intelligence of any triggered failure recovery mechanism and/or providing better, more meaningful failure reporting. A BFD session is established between the local and remote host nodes for each L3 communication path between them, e.g., for each unique pairing of local and remote network attachment points. Upon the occurrence of an L3 connection failure, the pattern of up/down states for these BFD sessions is analyzed, along with knowledge of the involved network topology, to determine the apparent location of the L3 connection failure.

  • Patent number: 8116280
    Abstract: A first group of core network (CN) nodes are arranged for transmitting a change request from a source to a target radio network controller (RNC), to a CN node selected from the set of CN nodes to which the target RNC is connected. Relating to a communication in progress with a first RNC (11) and a first CN node (13), for which a change from the first to a second RNC (12) is requested: the change request is transmitted from the first CN node to a second CN node (14) of the first group, and is forwarded from the second to a third CN node (15) selected, according to predetermined criteria, from the set of CN nodes to which the second RNC is connected.

  • Publication number: 20070007825
    Abstract: An uninterruptible power supply (UPS) includes a plurality of UPS modules. Each of the UPS modules has a battery that provides power to a protected load in the event of a utility power failure. A plurality of controllers control how much power each of the batteries deliver to the protected load, and a communication bus allows the controllers to exchange information about the battery voltages. One of the controllers calculates the average battery voltage of the plurality of batteries and adjusts the amount of energy provided by an individual battery such that the battery voltage is about equal to the average battery voltage.

  • Publication number: 20060290205
    Abstract: An uninterruptible power supply (UPS) system includes a first UPS module that has a first power source, a second power source and a controller operable to selectively connect the first or second power source to a load. A second UPS module is connected in parallel with the first UPS module. The second UPS module also includes a first power source, a second power source and a controller operable to selectively connect the first or second power source to a load. The controller of the first UPS module gradually transfers power from the first power source of the first UPS module to the first power source of the second UPS module to detect the presence of the first power source of the second UPS module.

  • Publication number: 20050184592
    Abstract: Devices and methods for improved voltage source transfer switching. First and second voltage sources (primary and alternate) are connectable to a load via corresponding first and second switches, which may comprise SCRs. A controller operates the switches according to various transfer methods. In some transfer methods, the timing of the switching operation is critical. For example, switching times may be optimized to reduce or prevent transformer saturation due to the dc flux built up during the transfer event. The controller force commutates off the primary source switch by turning on the appropriate alternate source switch for a brief period of time. In this case, the alternate source switches are “pulsed” (rather than being turned on continuously), so that the switches will naturally commutate off at the next current zero cross. Subsequently, the volt-second balancing control logic will permanently turn on these switches at the appropriate time.

  • Publication number: 20050184591
    Abstract: This disclosure is concerned with devices and methods for voltage source transfer switching that reduces or eliminates transformer saturation due to DC flux built up during a transfer event. First and second voltage sources (primary and alternate) are connectable to a load via corresponding switches. A transformer is connected downstream of the switches. A controller operates the switches according to various transfer methods wherein a switching time is determined to minimize downstream saturation current.

  • Publication number: 20050034170
    Abstract: A communication circuit carries at least one signal including synchronizing intervals by which output of the signal by first apparatus coupled to the communication circuit is to be synchronized. A communication method includes selecting and modulating at least a portion of the duration of at least some of the synchronizing intervals. A modulator is provided for selecting and modulating at least a portion of the duration of at least some of the synchronizing intervals. Another communication circuit carries at least a first signal including frequencies in at least a first frequency band. A method of determining whether the first signal is escaping from the circuit includes transporting along the circuit apparatus adapted for receiving the first signal, detecting whether a received signal includes frequencies in the first frequency band, and producing an indication that the received signal includes frequencies in the first frequency band.

  • Patent number: 6751748
    Abstract: The present invention is a redundancy system in the interface between a wireless and packet-based telecommunications network. The redundancy system includes back-up support components coupled to hub broadcast routers. Because the back-up support component monitors all communications to the primary support component through the communications from the hub broadcast routers, the back-up support component can assume responsibility for the primary interface support component without excessive overhead in sending back-up file information to a redundant component.
