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.

13. A method of conditioning an upstream bandwidth, the method comprising:
-
converting a frequency dependent voltage stream into a time dependent voltage stream including periods of increased voltage; amplifying and maintaining the periods of increased voltages using a low pass amplifier and a peak detector; recording a peak value from a plurality of voltage series from within the output voltage stream, each series beginning with a measured voltage level exceeding a high voltage threshold and ending with a measured voltage level passing below a low voltage threshold; placing the peak values in a first buffer; periodically calculating a first buffer average; placing the each of the first buffer averages into a second buffer; determining whether the first buffer average is one of above and below a value range, the value range being one of the first buffer averages placed in the second buffer plus (+) an upper variance amount and minus (−
) a lower variance;adding an increment of attenuation to the upstream bandwidth when the first buffer is greater than the value range; reducing an increment of attenuation to the upstream bandwidth when the first buffer is less than the value range. - View Dependent Claims (14, 15, 16, 17)
