Title: UPSTREAM BANDWIDTH CONDITIONING DEVICE
Abstract:
An upstream bandwidth conditioning device that can be inserted into a signal transmission line of a CATV system on a premise of a user includes a main signal path and a filter array including a plurality of discrete signal filters coupled to the main signal path. Each of the signal filters is configured to reduce a signal level of at least one frequency portion of an upstream bandwidth. The device further includes a controller configured to select between a plurality of states. In at least two of the states at least one of the signal filters is selected such that a signal level of a lower frequency portion of the upstream bandwidth and a signal level of an higher frequency portion of the upstream bandwidth are reduced by a greater amount than a signal level of an intermediate frequency portion, which includes frequencies arranged between the lower frequency portion and the higher frequency portion.
