  • Long subscriber loops using automatic gain control mid-span extender unit
    Patent number: 7142619
    Abstract: Systems and methods are described for long subscriber loops using automatic gain control. A method includes extending a digital subscriber loop including: producing an output signal in a first direction from a variable gain amplifier at a mid-span extender unit responsive to an input signal in the first direction from the digital subscriber loop; monitoring a signal strength of said output signal in the first direction at the mid-span extender unit; generating a gain control signal responsive to the signal strength at the mid-span extender unit; controlling a gain of the variable gain amplifier at the mid-span extender unit responsive to the gain control signal; and controlling a second gain of a second variable gain amplifier at said mid-span extender unit responsive to said gain control signal to produce an output signal in a second direction from said second variable gain amplifier at said mid-span extender unit responsive to a second input signal in said second direction from said digital subscriber loop.

  • Fault detection for subscriber loop repeaters
    Patent number: 6842426
    Abstract: Systems and methods are described for fault detection for subscriber loop repeaters. A method includes monitoring an upstream signal on a digital subscriber loop for a fault detection signal that is added to said upstream signal at a repeater; and determining if a fault has occurred. An apparatus includes a digital subscriber loop fault detection system including: a receiver circuit that monitors an upstream signal on said digital subscriber loop for a fault detection signal that is added to said upstream signal at a repeater; and a logic circuit that determines whether a fault has occurred.

  • Long subscriber loops using automatic gain control
    Publication number: 20020105964
    Abstract: Systems and methods are described for long subscriber loops using automatic gain control. A method includes extending a digital subscriber loop including: producing an output signal from said first variable gain amplifier responsive to an input signal from said digital subscriber loop; monitoring a signal strength of said output signal; generating a gain control signal responsive to said signal strength; and controlling a gain of said variable gain amplifier responsive to said gain control signal. An apparatus includes a digital subscriber loop extender circuit including: a variable gain amplifier having a gain and providing an output signal in response to an input signal from a signal generator over a transmission medium, said output signal having a signal strength as a function of said gain; and a controller coupled to said variable gain amplifier, said controller generating a gain control signal that is feed back to said variable gain amplifier to automatically control said gain.
