--- ATU-R Physical Layer Info
Current SNR Margin - 15.0 This is a measure (in dB) of how good your data signal is relative to the noise on the line. This should be a high number and in any case no lower than around 6 dB. If it's low you could find the modem gets data errors or even sync problems.
Current Attenuation - 30.0 Measures (in dB) how much signal loss there is on the line - this should be a low number and in any case should be no more than around 60-65 dB.
Current Status:
No defects detected
No loss of framing detected
No loss of signal detected
No loss of power detected
No loss of signal quality detected

--- ATU-R Line Status
Line Coding - DMT
Line Type - Fast If this line says "Fast", you are on fastpath. Otherwise your line is interleaved.
Actual ADSL Mode - G.DMT
Requested ADSL Mode - Multi

In the above sample results, the line potential is not revealed to the end user. However, we can examine the SNR Margin and Attenuation numbers. In this case, the SNR margin is 15, which is much greater than the minimum of 6, and the Attenuation is 30, which is much lower than the maximum of 60-65. Therefore, this line would likely qualify for a speed upgrade. How much of an increase is possible cannot be known from this data, but these numbers are good indicators.
