  • Patent number: 7889744
    Abstract: A method and apparatus for automatic synchronization of monitoring points for a network management system (“NMS”) along a permanent virtual circuit (“PVC”) is disclosed. A NMS in an asynchronous transfer mode (“ATM”) network coupled to a plurality of ATM switches is operative to monitor each of the plurality of ATM switches storied in a monitoring service object corresponding to a PVC. The NMS receives at least one notification from at least one ATM switch of the plurality of ATM switches indicating an ATM switch has been added or removed from the PVC. In response to the at least notification, the NMS adds at least one ATM switch to the monitoring service object or removes at least one ATM switch from the monitoring service object.

  • Publication number: 20110012609
    Abstract: The innovation relates to systems and/or methodologies for error detection during sub-assembly in high voltage analog circuits. A signal driver communicates test signals to one or more high voltage analog circuits, and a state machine compares the electrical and/or thermal responses of the high voltage analog circuits to a set of predetermined expected results (e.g., signatures). The signal driver and state machine can be incorporated into the high voltage analog circuits. The expected results can be stored in the target circuits in the form of look-up tables, matrices, and so forth. Errors, such as, dry solders and bridge solders can be determined based on the comparison of the obtained responses to the expected signatures.

  • Patent number: 7773503
    Abstract: VoIP traffic bandwidth through a router port is controlled so that it does not exceed a predetermined bandwidth to ensure a desired quality of service for all VoIP calls routed through the port. Information of a packet received by the port is extracted from a packet header. The information includes source and destination addresses and port numbers as well as the bandwidth used by the packet. If the packet is from an existing call, the packet is routed and the time the packet was received is updated. If the packet is from a new call, it is determined whether the port has sufficient bandwidth to route the new call. If the port has sufficient bandwidth, the packet is routed, bandwidth is allotted for subsequent packets from the new call, and the port information is updated to accept the subsequent packets. If the port does not have sufficient bandwidth, the packet is dropped.

  • Patent number: 7551624
    Abstract: A communications system is described for enforcing a service level agreement for a specified customer on a network. The communications system includes a router to receive at least one packet containing data. A management system is in communication with the router, where the management system provides access control commands to the router for the specified customer based upon an agreed upon codec and an agreed upon packet length. A detection system is in communication with the router. The detection system extracts a codec information and a packet length information from the packet. If the codec matches the agreed upon codec and the packet length matches the agreed upon packet length, then the packet is allowed to proceed. Otherwise the packet is dropped from the network.
