Abstract
A premise signal conditioning device is provided that can be inserted into a signal transmission line of a CATV system on a premise of a user. The device includes at least a first diplexer set, each diplexer set including a supplier side diplexer and a premise side diplexer creating a return path for an upstream bandwidth and a forward path for a downstream bandwidth there between. The device further includes a detector configured to measure a level of signals present in a first segment of frequencies between the upstream bandwidth and the downstream bandwidth. The device further includes a switch controller configured to alter a width of the return path from a first width to a second width in response to a level of the signals exceeding a predetermined threshold level.
