  • Patent number: 10929311
    Abstract: Methods and systems for backing up data to a target device are described. According to some embodiments, the method receives a first set of data packets for backup, where the first set of data packets includes a multiplicity of data chunks. The method further captures footprints of the first set of data packets in a cache disk array. In response to receiving an acknowledgement from the cache disk array indicating the footprints have been captured, the method further initiates a write operation to write each data chunk of the first set of data packets to the target device. In response to receiving an acknowledgement indicating the data chunk is successfully written, the method further flushes the respective footprint of the data chunk from the cache disk array.

  • Patent number: 8457181
    Abstract: Methods and apparatus for maintaining the maximum achievable data rate on a DSL line, up to and including a rate to which a user subscribes is described. Performance monitoring is conducted on the DSL line on an ongoing basis to determine noise margins in each direction. Each noise margin is compared against pre-determined decreasing/increasing thresholds to determine whether the line characteristics dictate a data rate change without loss of synchronization. The invention supports dynamic provisioning changes including application driven service level change requests, e.g., new bandwidth-on demand services. In some embodiments, a combination of existing and new embedded operations channel (EOC) messages are used to implement the modem data rate changes. New EOC messages may be implemented using some of the reserved and/or vendor proprietary Opcodes currently permitted. Modem assigned data rate changes are implemented without a disruption of service, e.g.

    Abstract: A VOX interface is provided that interfaces with at least two communication paths to two separate devices. One communication path may be to a first electronic device, such as a central monitoring station remote from the VOX interface, and another communication path may be to one or more remote devices, such as to one or more patient devices remote from the VOX interface. The VOX interface may determine which of the communication paths is sending a signal (such as an audio signal), and configure the VOX interface (via one or more switches) to pass the signal through. Specifically, the VOX interface may sense signals indicating the presence of audio from a central station audio bus and the patient station bus, may do some background noise filtering on the signals, and may pass these filtered values through a differentiator circuit to determine which bus presented the audio.

    Abstract: A PNPN structure thyristor and a third P-type impurity region are formed on a semiconductor substrate, and a fixed current circuit using an NPN transistor 20 and a resistor 30 is connected to a cathode terminal K and a gate terminal G of a composite element 10 that has a P-channel MOS transistor Q3 with the third P-type impurity region as a drain connected to a PNP transistor Q1 of the thyristor. If a voltage applied to the anode terminal A of the composite element 10 rises from 0V, initially the thyristor is on and current flows, but once the threshold voltage of transistor Q3 is reached transistor Q3 turns on. A short circuit then exists between the base and emitter of transistor Q3 of the thyristor and current of the composite element 10 itself is cut off. Because of the bipolar structure it is simple to configure a small integrated circuit with a high withstand voltage.

  • Patent number: 6807261
    Abstract: A clock generating circuit generates a clock of a rate corresponding to a Dch rate in response to a specification from the exterior. A counting circuit detects completion of reception of one frame by counting the clock number up to “11” at timing at which a start bit detecting circuit detects a start bit in a serial signal. An S/P converting circuit fetches a serial Dch signal bit by bit in synchronism with the clock, outputs the latest fetched 10 bits in a parallel form and latches eight bits of a real data portion among the output data into a latch circuit at the time when reception of one frame is completed. In parallel with the above operation, a parity calculating circuit and flag/interruption generating circuit set various flags and generate a reception completion interruption.

  • Patent number: 6807262
    Abstract: A switch based feature that allows subscribers to adjust their incoming or outgoing audio signal strength. The value of the transmit or receive pad values on the subscriber line card are adjusted to control the strength of the audio signal transmitted to, or received from, the network. The subscriber controls the feature by sending a hook flash to the switch, entering the DTMF keypad feature code and transmit or receive volume parameters, and then returning to the call.

  • Patent number: 6661883
    Abstract: The invention provides a key system unit comprising a first interface suitable for connection to a plurality of local terminals and a control unit coupled to the first interface. The control unit is operative for receiving a user data signal from the first interface and routing the user data signal toward a selected destination. The control unit has a registry for storing status information, the status information including a local segment and at least one remote segment, the local segment providing a representation of the functional status of the key system unit, the remote segment providing a representation of the functional status of a remote key system unit. The information in the registry can be displayed on a display screen on a local terminal to provide the user with system status information on the local key system unit and the remote key system unit.
