There isn't an NDA. I'm just not sure what I'd be allowed to say. I don't know what's in the public domain and what isn't, best to only say what people will figure out of their own accord.
But back to the SNR, it can be 3dB, 4dB or 5dB. It doesn't have to jump right down to 3. It'll depend on the line. Obviously if your line is already on 10dB or higher it seems unlikely you'd ever see any benefit from this trial, DLM won't suddenly reduce the SNR to under 6 just because you happen to be in a trial area.
Was there ever an official declaration about the BT Wholesale ADSLx one getting 3dB?
I don't believe there was, no.
