Noise margin (dB) : 29.9
If your NM is reducing from 30 dB upon connection, the Target NM set by the DLM on your line, to 6 dB as time goes by then your line is very noisy and the DLM has set a very high Target to overcome the noise and guard against discons. Tho' I've never heard of such a high Target.
I guess you get switched to ADSl2 sometimes cuz your line is so unstable and cuz ADSL2 is less susceptible to noise you get a higher sync speed.
