Description 
The Multimedia Line Equalizer/Reverse Conditioner 
(LEQ/RC) is a by-product of the extensive reverse path 
studies that Scientific-Atlanta has been conducting.  This 
analysis has conclusively determined that, by strategically 
attenuating the reverse path signals, systems are able to 
better support transmission in the challenging portion of the 
spectrum. 
 
This reverse path attenuation has several key benefits.  First, 
it raises the output levels of communicating devices (e.g., 
home communications terminals, cable modems and cable 
telephone NIUs) to the upper ends of their dynamic ranges, 
thereby increasing overall signal-to-noise performance.  
Second, by lowering their dynamic range variance, 
deployment of new services is simplified.  Third, the additional 
reverse attenuation minimizes concerns about overdriving 
optical return transmitter lasers.
