Abstract
An upstream bandwidth conditioning premise device for use as part of a CATV system and for placement on or near a user's premise to reduce noise created on the user's premise that would otherwise be injected into upstream transmission channels and passed into an RF main signal distribution system of the CATV system. The device includes a variable attenuation device, a signal measurement circuit, a memory circuit and an electronic circuit, which is configured to iteratively determine (i) whether an incremental amount of additional attenuation is to be applied and (ii) whether at least a portion of a previously applied incremental amount of attenuation is to be removed. The electronic circuit includes a counting circuit, a threshold comparison circuit configured to compare a peak signal strength to a predetermined threshold, and a peak comparison circuit configured to compare a contemporary peak signal strength to a previous peak signal strength.
