Upstream bandwidth conditioning device

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.
