Abstract:
The present disclosure provides methods and systems for a network interface device including an entry port connected to a cable television (CATV) network. A noise suppressor is provided that improves the detection and differentiation between ingress noise and valid upstream signals. The noise suppressor can gate the upstream path logically and dynamically to pass valid upstream signals, while blocking ingress noise form the CATV network.

Claim (Index 1):
A network interface device for dynamically controlling ingress noise, the network interface device comprising:\n an entry port configured to connect to a cable television (CATV) network; an input/output port configured to connect to subscriber equipment; an upstream path configured to communicate an upstream signal from the input/output port to the entry port; a noise suppressor in the upstream path and comprising a plurality of noise suppression paths, the noise suppressor comprising a switch configured to route the upstream signal through a selected one of the plurality of noise suppression paths, wherein at most one of the plurality of noise suppression paths is active to transmit the upstream signal from the input-output port toward the entry port at any time, and wherein a different level of noise suppression is applied to the upstream signal in the respective noise suppressions paths; and a controller configured to:\n compare a continuous power level of the upstream signal in the upstream path and the instantaneous power level of the upstream signal in the upstream path; \n determine a dynamic ingress noise threshold based on the comparison of the continuous power level and the instantaneous power level; \n determine a signal-to-noise ratio of the upstream signal; \n compare the signal-to-noise ratio with the dynamic ingress noise threshold; and \n output a control signal to the noise suppressor selecting one of the plurality of noise suppression paths based on the comparing of the signal-to-noise ratio with the dynamic ingress noise threshold, wherein the noise suppressor is configured to route the upstream signal to the selected one of the plurality of noise suppression paths in response to the control signal.
