| 20120099629 | Communications Wiring Noise Level Monitor and Alarm Indicator - In an apparatus and method of testing the capacity of a network to support DSL services, a test device is coupled to a pair of wires (e.g., Tip-Ring) that support DSL services between ATU-C and ATU-R modems. In operation, the test device: samples for a DC line feed or potential on the wires when the ATU-R and ATU-C modems are operatively connected via the wires; samples for AC noise present on the wires when the ATU-R modem is electrically isolated from the ATU-C modem which is operatively coupled to the wires; samples for DSL signals output by the ATU-R modem when the ATU-C modem is electrically isolated from the ATU-R modem; and samples for DSL signals on the wires when the ATU-R modem is operatively coupled to the ATU-C modem via the wires. Based on these samples, the test device determines the capacity of the network to support DSL services. | 04-26-2012 |
| 20120099436 | Integrated Ethernet over Coaxial Cable, STB, and Physical Layer Test and Monitoring - In a method of testing a residential broadband communication network, a residential gateway or set top box (STB) performs one or more single-ended parametric tests of the residential network that runs therebetween. The residential gateway or STB also performs one or more single-ended reflectometry tests of the residential network that runs therebetween. The residential gateway and the STB perform one or more dual-ended tests of the residential network that runs therebetween. The residential gateway dispatches the results of the foregoing tests to either: a device on the residential network, a device of another network that supplies broadband services to the residential network, or an intelligent device coupled to the residential gateway. | 04-26-2012 |
| 20100278050 | SYSTEM AND METHOD FOR MAKING FAR END MEASUREMENTS FOR DSL DIAGNOSTICS - A system is provided for identifying service affecting conditions in an access portion of a network through which a number of subscribers are connected to an exchange. The access network includes subscriber lines connected to DSL subscriber modems. The system includes a receiver for receiving pilot signals from a modem connected to one of the subscriber lines. A measuring unit is operatively associated with the receiver for measuring electrical characteristics of the received pilot signals. A controller is operatively associated with the measuring unit and uses the measured electrical characteristics to identify a service affecting condition. The subscriber modem pilot signals include differential mode signals and the measuring unit measures common mode of each wire of the subscriber line. By using combinations of measurements and deductive logic, the system can detect one or more service affecting conditions. | 11-04-2010 |
| 20100128768 | METHOD AND APPARATUS FOR REMOTELY TESTING A DIGITAL SUBSCRIBER LINE ACCESS MULTIPLEXER - A system and method for testing a modem of a digital subscriber line access multiplexer (DSLAM) includes a pair of modems communicatively coupled to each other by way of a communications path that includes a first DSL communication medium connected to one modem, a second DSL communication medium connected to the other modem, which is part of the DSLAM, and an Ethernet medium connected between the first and second DSL modems. DSL signals can be dispatched from the first (or second) modem via the first (or second) DSL communication medium for receipt by the second (or first) DSL modem via the second (or first) DSL communication medium, whereupon, DSL signals passing from the first DSL communication medium to the second DSL communication medium, or vice versa, are converted into Ethernet packets for transmission over the Ethernet medium and then back into DSL signals. | 05-27-2010 |
| 20100110894 | AUTOMATIC PROVISIONING OF A REMOTE TEST HEAD OF A COMBINED IP/TELEPHONY/CABLE NETWORK - In a telecommunications network that includes: a Digital Subscriber Line Access Multiplexer (DSLAM) ( | 05-06-2010 |
| 20100013457 | Power Line Takeoff Clamp Assembly - In a power line takeoff clamp assembly and method of use thereof an electrical power distribution line is clamped to a body of the clamp assembly. A power takeoff supported by the body clamped to the power line generates direct current from alternating current flowing in the power line. One or more sensors supported by the body clamped to the power line sense one or more values related to an electrical current flowing in a power line. A wireless transceiver supported by the body clamped to the power line communicates data regarding the one or more sensed values. Each sensor and the wireless transceiver utilize direct current generated by the power takeoff for the operation thereof. | 01-21-2010 |
| 20090240449 | Power Distribution Monitoring System And Method - A power distribution monitoring system includes a number of power line mounted monitors. Each monitor can acquire data regarding the delivery of electrical power in the power line, wirelessly transmit and receive messages, and electromagnetically acquire and store operating electrical power from electrical current flowing in the power line. The system also includes an aggregator that can wirelessly transmit and receive messages and wirelessly output beacon messages. In response to beacon signals wirelessly output by the aggregator, each monitor co-acts with the aggregator to dynamically build a wireless communication network for the wireless communication of the data acquired by the monitor regarding the delivery of electrical power in the power line to the aggregator. | 09-24-2009 |
