Network interface device and method having passive operation mode and noise management
First Claim
Patent Images
1. A network interface device comprising:
- an active branch circuit configured to transmit an active branch signal to an active subscriber device;
a noise controller configured to detect whether the upstream signal includes a noise indicative power level, and control transmission of the upstream signal through the active branch circuit based on the detection of whether the upstream signal includes a noise indicative power level and based on whether the noise controller is in a powered state and an unpowered state; and
a bypass circuit configured to transmit the active branch signal through a bypass signal path when the noise controller detects that the upstream signal includes a noise indicative power level so as to prevent the upstream signal from being transmitted through the active branch circuit when the upstream signal includes the noise indicative power level and when the noise controller is in the unpowered state, andwherein the bypass circuit is configured to transmit the upstream signal through the active branch circuit only when the noise controller detects that the upstream signal does not include the noise indicative power level so as to allow the upstream signal to be transmitted through the active branch circuit only when the upstream signal does not include the noise indicative power level and when the noise controller is in a powered state.
