Recommended levels from output of show dsl interface command

If I run the command "show dsl interface atm0" on my ADSL routers, I get a lot of information.

From the following link, it tells me what each line relates to e.g. "Noise Margin" = "Noise Margin, in decibels" and "Attenuation" = "Attenuation of the signal, in decibels" etc.

But what I really want to know is what typical values are for each of these items. And values in what range would indicate a problem? (and, if possible, what the likely cause of the problem is?)

For example, what are the recommended ranges of values for Capacity used, Noise margin, Output power, Attenuation, etc - and what do these values actually tell me about the health of my ADSL connection?

Does anyone have any information on the above?

Thanks.

The default value for noise margin is 6 dB downstream, 6 dB upstream. To set the upstream and downstream CAP signal-to-noise ratio (SNR) margin values for a selected profile, use the cap margin command. Use the no form of the command to set the margins to the default values.

cap margin downstream cap-margin upstream cap-margin
