It only takes an RF oscillator at 40MHz producing +70dBmV to shut the return path lasers down

How many people here have any idea what this is supposed to mean?
More to the point find me a cableco whose return paths are set up to handle that powerful a signal. As you very well know this is why power budgets are calculated across the coaxial segments and amplifiers set as they are so that when signals hit the fibre nodes they aren't at an excessive power to overdrive lasers to clipping or shutdown point.
Amazingly enough people opening up cabinets and inserting oscillations onto return path is not exactly common, and the naturally occuring impediments I've seen don't come close to doing this.
You also might like to know we're using a different supplier to the one you probably worked with now.
Nice try again though.
EDIT: Apologies to those wondering what the hell, he was trying to make out ntl's network is substandard because firing a signal a hell of a lot stronger than it's specified to handle will break it... duh.
