    摘要: A ringing voltage power management circuit is configured to extract an isolated high-value intermediate voltage from a central office powered digital subscriber line through a current limiting circuit, and to charge a storage capacitor that serves as an energy reservoir for the ring generator of a subscriber line circuit. The storage capacitor and the current limiting circuit isolate the peak power drawn by the ringing load from the telephone line and translate the ringing signal's (20 Hz) ripple to the sub-Hz oscillations of the ringing cadence.

    摘要: A power management circuit for a remote access platform extracts power from a wireline for powering a ring generator that generates a ringing voltage signal that is distributed to a plurality of subscriber circuits. A power-limited voltage converter steps up the wireline voltage to a higher ‘isolating’ voltage, charging a capacitor coupled to the ring generator. A monitor circuit reduces the power that the power-limited voltage converter can draw, if the wireline voltage drops too low. This prevents the wireline voltage from collapsing should the remote terminal be deployed at a distance from wireline voltage source (the central office) greater than its specified capability.

    摘要: A redundant ringing signal generator subdivides a ringing signal bus into multiple ringing bus segments. A plurality of redundant ringing voltage generators sourcing internally and/or externally ringing voltages are individually and selectively connectable to the multiple ringing bus segments. In the event of a prescribed anomaly in the ringing signal sourced by a ringing generator, the faulty ringing signal is automatically disconnected from its associated ringing bus segment, and that ringing bus segment is connected to a redundant ringing signal source, provided by either the same or another ringing generator.

    摘要: Whether or not protection circuitry for a span-powered remote digital subscriber loop unit is properly connected to earth ground is determined by the deliberate assertion and detection of a ground fault from a central office line card location. The span-powered remote unit is augmented to place a controllable conduction path in circuit with the span-powered loop and an earth ground pin. If the earth ground pin has been properly connected to earth ground, applying the conductive path will place a ground fault on the span, which is detected by a ground fault detector within the central office line card. If the ground fault detector does not detect a ground fault in response to the application of the conductive path, the line card forwards a negative ground fault event message to a test center, so that a service technician may be dispatched to the remote unit to correct the problem.

    摘要: A power management system is interfaced with both a local utility power source and a remotely powered span, and monitors the power availability for and requirements of DDS terminal equipment. Upon detecting that local utility power is insufficient to operate the terminal equipment, a power limited converter derives power from the phone line. The span power drawn is limited to a fixed value that prevents the line from collapsing. An auxiliary capacitor stores energy from either local utility power or the span, to provide for periods of extended power operation (including ringing the phone).

    摘要: A power supply includes a rectifier circuit having a rectifier mode and a voltage doubler mode. An AC switch is coupled to the rectifier circuit and switches the rectifier circuit into the rectifier mode when a higher AC line voltage is supplied and a voltage doubler mode when a lower AC line voltage is supplied. A control circuit is connected to the AC switch and detects the higher or lower AC line voltages and is operable for latching the rectifier circuit in the rectifier mode when the higher AC line voltage is detected and in the voltage doubler mode when the lower AC line voltage is detected. The latch circuit maintains a latched configuration in either the rectifier or voltage doubler mode during voltage transients and in the rectifier mode during start-up transients.

    摘要: An adaptive power supply span powers devices used in telecommunications. It includes a power circuit and control circuit that receives power and sense signals therefrom and provides a control signal thereto and distinguishes between a first network interface load having a constant voltage input power requirement and a second network interface unit load having a constant current input power requirement. A voltage control circuit and current control circuit are interconnected together and connected to the power circuit. A control signal from the voltage control circuit and current control circuit extends to the power circuit. The control circuit maintains a fixed output voltage for constant voltage regulation for the first network interface unit load, if the output current remains below a threshold current. The circuit limits the output current to a regulated value for constant current regulation below the initial maximum value for powering a second network interface unit if the initial output current is greater than the threshold current for a time greater than a threshold time.

    摘要: A electrical power control mechanism ensures start-up of all telecommunication devices (repeaters and a remote terminal) along a span-powered wireline. Input voltage start-up thresholds of power control circuits at the devices are higher than the steady-state voltage across the repeater closest to the span supply, when the span voltage is at a minimum DC wireline voltage that sustains operation of all devices. The maximum input voltage start-up threshold of a device is less than the maximum voltage that could be applied during start-up, and the remote terminal has an input voltage start-up threshold value higher than that of any repeater. The maximum standby current of each device is specified, and input power is limited to its steady state maximum during start-up.
