Abstract

A device may be used for conditioning an upstream bandwidth. The device includes a return path extending at least a portion of a distance between a supplier side connector and a user side connector, and a coupler connected within the return path, the coupler providing a secondary path. A detection circuit is connected electrically downstream the coupler, and a level detector is connected electrically downstream the detection circuit. A microprocessor is connected electrically downstream the level detector. The microprocessor includes a first buffer and a second buffer. A variable signal level adjustment device is connected within the return path electrically upstream from the coupler. The variable signal level adjustment device is controlled by the microprocessor.
