US 10,476,608 B2 · Network interface devices with upstream noise suppressors

Abstract

A network interface device includes an input-output port; an entry port; an upstream signal path configured to carry an upstream signal from the input-output port to the entry port; a noise suppressor, in the upstream signal path, that includes noise suppression paths between the input-output and entry ports; and a controller configured to: determine a first power level of the upstream signal in a first frequency band; determine a second power level of the upstream signal in a second frequency band; generate a control signal based on a first comparison of the first and second power levels, on a second comparison of the second power level with a threshold limit, or on the first comparison of the first and second power levels and on the second comparison of the second power level with the threshold limit; and select one of the noise suppression paths based on the control signal.

Dependent claims

A network interface device, comprising:

an input-output port;
an entry port;
an upstream signal path configured to carry an upstream signal from the input-output port to the entry port;
a noise suppressor, in the upstream signal path, that comprises first and second noise suppression paths between the input-output port and the entry port;
and
a controller configured to:
determine a scaled first power level of the upstream signal in a lower frequency band;
determine a second power level of the upstream signal in a higher frequency band;
and
select the first noise suppression path in response to the scaled first power level being greater than the second power level, or in response to the second power level being greater than a threshold limit.
