Re: New Model: Westell 2200 DSL Modem
Hey, maybe Westell would like to test this product on a marginal phone line with a year's worth of sync, noise margin and even tone-selection data! 
But I'm getting totally confused trying to decode this - perhaps marketeers are too involved. Power Spectral Density isn't new and shaping PSD is what occurs to some extent when negotiating an ADSL connection (selection of the discrete tones from the available array). The rules of PSD are defined by regulatory specifications to insure phone lines don't radiate/crosstalk. Of course, some innovative way of doing this can certainly be a breakthrough technology.
But if things work better it's a moot point. Any other speculations what's going on? |

My guess: new analog front end + better signal extraction algorithms in the DSP.

| I agree, Dan. Buried in the DMH blurb is the 4-Hybrid circuits, dynamically selected. I think this is a key to the technology. With DSPs it's hard to separate analog from digital anymore. |
