  • Patent number: 10698444
    Abstract: A docking station having adaptor function contains: an AC-DC conversion module, a charging module, a control module, and at least two interface modules. When an AC power source outputs AC power into the AC-DC conversion module, the AC-DC conversion module outputs two DC powers to the charging module and the control module according to the AC power. The control module is enabled to operate according to the first DC power. And, according to the second DC power, the control module controls the power charging module to charge each target end-user devices being connected to a corresponding interface module. When interface modules respectively connect to target end-user devices, the control module controls the signal transmission sequence of interface modules to provide data transmission paths amongst the end-user devices via the interface modules. The docking station also serves as an accessory for supplying electric power to an end-user device for endurance use.

All of the subscriber Customer Premises Equipment connected to the DSLAM each provide a portion of the required power to the remote cabinet via the telephone line connecting the DSLAM and the subscriber CPE. The CPE at the subscriber premises is already connected to power mains in the subscriber premises so, providing power, via the telephone line to the outdoor cabinet is relatively simple. The remote cabinet includes a circuit for receiving the power input from each subscriber and then distributing the power, required by the DSLAM load, equally among the subscribers.

  • Patent number: 9859951
    Abstract: A PoDL system includes a PSE connected via a wire pair to a PD, where differential data and DC power are transmitted over the same wire pair. Typically, low voltage/current detection and classification routines are required upon every powering up of the system to allow the PD to convey its PoDL requirements to the PSE. Various techniques are described that simplify or obviate such start-up routines or enable increased flexibility for the PoDL system. Such techniques include: ways to specify a particular PD operating voltage; ways to disable the PD's UVLO circuit during such routines; using opposite polarity voltages for the two routines; using voltage limiters or surge protectors to convey the PoDL information; detecting loop resistance; using a PSE memory to store previous results of the routines; and powering the PD communication circuit using the wire pair while the PD load is powered by an alternate power source.

  • Patent number: 8897431
    Abstract: Power is supplied to telecom equipment in DSLAM outdoor/remote cabinets with relatively short distances between the subscriber and the cabinet. All of the subscriber Customer Premises Equipment connected to the DSLAM each provide a portion of the required power to the remote cabinet via the telephone line connecting the DSLAM and the subscriber CPE. The CPE at the subscriber premises is already connected to power mains in the subscriber premises so, providing power, via the telephone line to the outdoor cabinet is relatively simple. The remote cabinet includes a circuit for receiving the power input from each subscriber and then distributing the power, required by the DSLAM load, equally among the subscribers.

  • Patent number: 8866337
    Abstract: Techniques are provided for providing power onto multiple power distribution paths. Power controller devices receive power from a power source device and are coupled to first and second multiplexer units. The multiplexer units receive power from the power source devices via the power controller devices for first and second power distribution paths. A multiplexer control unit controls the multiplexer units to output power from the first power distribution path, the second power distribution path or both of the paths. Power subsystems are provided comprising first and second power transistor units. The first transistor unit receives power from the first multiplexer unit over the first path and the second transistor unit receives power from the second multiplexer unit over the second path. Ports are provided and are coupled to a powered device. The multiplexer control unit controls the multiplexer units to supply power to the respective ports according to the type of powered device detected at a port.

  • Patent number: 8867736
    Abstract: A control device includes a circuit operable to sense an analog input voltage dependent on a line current flowing via a communication line of a terminal generate an analog difference voltage in a constant line current operation based on a difference between the sensed analog input voltage and an analog feedback voltage which depends on an adjustable nominal direct-current value and filter a sequence of control error values from a sequence of digital difference voltage values converted from the generated analog difference voltage. The circuit is further operable to convert a control value generated from the sequence of control error values in the constant line current operation to an analog direct voltage for supplying the terminal and convert the nominal direct-current value into the analog feedback voltage in the constant line current operation.

  • Patent number: 8553848
    Abstract: Systems and methods can provide for preventing a false alarm generated during a planned network outage during a maintenance window. Security systems can generate and report alarms to a security center through a communications network. Intruders are known to disable the communication network thereby preventing reporting of an alarm to the security center. Security systems can generate local alarms upon detecting loss of the communications network. It is advantageous for a communications network operator to prevent false alarm generation during periods of planned network outages.
