Abstract
Processing a signal originating from a node port experiencing ingress. A node that provides service to a plurality of cable modems will generally have a plurality of node ports. The node may be a Remote PHY Node or a Remote MACPHY node (RMN) for example. A detection is made that a particular node port of the node is experiencing ingress. In response, an upstream signal originating from the particular node port is analyzed to dynamically determine an amount to attenuate the upstream signal. The upstream signal is attenuated the dynamically determined amount prior to the signal being processed at an active device upstream from the particular node port experiencing the ingress. Distortion and/or saturation of the signal at the active device is advantageously prevented.
