Abstract
Systems and methods are described for digital subscriber loop repeaters. A method of transforming a digital subscriber loop signals includes increasing a gain with a digital subscriber loop repeater including: isolating an upstream signal band by passing an upstream signal through an upstream pass filter; amplifying the isolated upstream signal with an upstream amplifier; isolating a downstream signal band by passing a downstream signal through a downstream pass filter; and amplifying the isolated downstream signal with a downstream amplifier. The systems and methods provide advantages because DSL can be provided over long loops and/or over coil loaded loops.
Claims8
A method of transforming a digital subscriber loop signal, comprising:
- providing the digital subscriber loop signal;
- increasing a gain of the digital subscriber loop signal with a digital subscriber loop repeater;
- and
- querying the digital subscriber loop repeater for a purpose selected from the group consisting of controlling the operation of the digital subscriber loop repeater and determining the status of the digital subscriber loop repeater,
- wherein controlling the operation of the digital subscriber loop repeater includes provisioning the digital subscriber loop repeater with an operational mode selected from the group consisting of normal, no-ADSL-repeater with coils in circuit, and no-ADSL-repeater with coils out of circuit.
