[RFI] Spectrum RFI Tracking

[Larry Benko]

Not really Paul.  I think they are somewhat in denial and they believe 
the only way VDSL2 radiates is if there are wiring problems.  I think a 
better statement is that if the wiring is perfect the RFI is fairly 
close to the noise level but this is not true for most installations.
