  • Patent number: 11825529
    Abstract: Disclosed herein are systems and methods for facilitating wireless communication of a wearable device. In one aspect, a wireless device receives a paging message from a cellular network, via a wireless link between the wireless device and a companion device. The paging message can be received while a cellular modem of the wireless device is operating in reduced power mode and not registered with the cellular network, and the companion device is registered with the cellular network. The wireless device can transition the cellular modem from the reduced power mode to an active mode in response to receiving the paging message via the wireless link with the companion device. The wireless device can register with the cellular network after the modem has transitioned to active mode, to establish a cellular link directly with the cellular network.

  • Patent number: 11229947
    Abstract: A method of manufacturing a valve body having one or more corrosion-resistant internal surfaces. The method involves performing a casting process, which includes pouring a first material into a mold box, to produce a valve body casting made of the first material. During the casting process, a layer of a second material is formed on one or more internal surfaces of the valve body casting, the second material having a higher corrosion resistance than the first material, by: (1) applying, with an additive manufacturing technique, the second material to one or more external surfaces of a core, and (2) inserting the core into the mold box. A portion of the first material binds to the second material on the one or more external surfaces of the core while the first material is poured into the mold box.

    Abstract: A method, system, and medium are provided for generating a profile for public safety answering platforms (PSAP). The profile identifies media formats supported by the PSAPs at various cell sector locations maintained by a network provider. A network server selects a cell sector and generates a first test emergency services call and subsequent test emergency services calls. The test emergency services call is transmitted to a PSAP. During the session with the PSAP, the subsequent test emergency services calls are processed to determine mid-call support for additional multimedia formats or codecs. The PSAP generates responses that indicate whether the PSAP supports a multimedia format or codec identified in the test emergency services call or the subsequent test emergency services call. The PSAP transmits the responses to the network server for storage in the profile.

  • Patent number: 8139720
    Abstract: A first clock signal is generated by a first circuit and a second clock signal is generated by an auxiliary clock circuit. A switch controls whether the first clock signal or the second clock signal is provided to a subscriber line integrated circuit (SLIC). The SLIC is operable to generate a line voltage within predetermined tolerances on a loop line at a customer premises if the SLIC is receiving the first clock signal or the second clock signal. A resync signal is sent to the SLIC to cause it to resync with the first clock signal without going through a reset operation.

    Abstract: In a computer, a test script is received that includes a first set of commands to be provided to an Internet protocol (IP) telephone. The test script is parsed to obtain the first set of commands. Parameters that identify the telephone are obtained. The parameters and at least one of the first set of commands are used to obtain at least one corresponding second command from a conversion table. A command script is generated to be executed by the telephone, the command script including the at least one corresponding second command.

  • Publication number: 20120039448
    Abstract: A device may automatically place a call to a call routing device based on one of a list of numbers or addresses. The call may be forwarded by the call routing device to a call agent device. The device may also establish a session with the call agent device to which the call is forwarded by the call routing device and automatically receive, from the call agent device, a message that includes an identifier for a virtual call agent. The device may extract the identifier from the received message, compare the extracted identifier to an identifier that is associated with the call, and determine whether the call routing device correctly forwarded the call based on the comparison.

  • Patent number: 8107615
    Abstract: The invention relates to a method and to a device for testing the function for inverting the polarity on a subscriber connection line (TAL) comprising several wires (a, b), in order to connect at least one subscriber to a subscriber connection line (SLM), which comprises at least one inverting device (RG) and a current measuring device (MG) which is associated with the inverting device (RG). In a first step, the subscriber connection component (SLM) is separated from the inverting device (RG) and forces physical inversion on the wires (a, b) of the subscriber connection line (TAL). In a second step, the inverting function of the inverting device (RG) is activated. In a subsequent third step, the subscriber connection component (SLM) is separated from the device (DC) which forces the physical inversion and is connected to the inverting device (RG). The correct function of inversion is tested during all three steps by measuring the direction of the current flow.

  • Patent number: 8064899
    Abstract: A system and method for network monitoring are disclosed. In one embodiment, a network monitoring method includes determining that a caller can receive audible information via a first access device and graphical information via a second access device. The method also includes converting a request communicated by the caller via the first access device to a directive for a network management engine to retrieve network management information related to at least one monitored network device. The method also includes translating a first portion of the network management information to a first format for communication to the first access device and translating a second portion of the network management information to a second format for communication to the second access device.

    Abstract: A method for automatically configuring an interface unit (112, 212, 912, 1012, 1112) for connecting a headset (110, 210, 910, 1110) and a telephone (100) by electrical connections (992, 993, 1092, 1093). The electrical connections (992, 993, 1092, 1093) between the interface unit (112, 212, 912, 1012, 1112) and the telephone (100) comprise two pairs of electrical paths having a number of distinct permutation settings. Each of the number of distinct permutation settings have a complementary setting together forming a number of distinct complementary setting pairs. The method comprises the steps of: a) receiving a test signal, b) for each distinct permutation setting generating an output signal in response to the test signal, c) determining a least preferred distinct permutation setting based on the output signals, d) selecting the complementary setting to the least preferred distinct permutation setting as a preferred setting.

  • Publication number: 20110249808
    Abstract: Systems and methods for calls per second network testing are disclosed. The methods may be performed by a network testing system or other computing device. The method may include receiving user selection to create a network test. A user specification of a bulk network calls test type and the call transmission criteria for the network test are received. The call transmission criteria may include a number of calls per second and one of either a talk time or a number of channels. When the talk time is specified, the number of channels is calculated. Similarly, when the number of channels is specified, the talk time is calculated. User selection to begin the network test is received, and packets are transmitted for the network test according to the call transmission criteria. During transmission, the call transmission criteria are recalculated at a system defined interval to avoid bursts.
