These results correspond when running a line test on Netway.
Relative Capacity
Percentage of line being used to keep in synch. Alone Relative Capacity is useless to diagnosis a problem, but when checked against Noise Margin and Bit Rates. You can tell if there is a loop problem, bridge tap, and other conditions that would be affecting quality of service. Ideally a lower number here is what you want to see.
Noise Margin
Represents the relative noise on the line as compared with signal strength measured in SNR (Signal to Noise Ratio). Max Value:31 Min Value:0
 
NOTE: If these values drop below 6 could indicate a possible problem. DSL modems can synch at 6 or lower but in this situation you should check Relative Capacity and Bit Rates to make sure things are ok. Ideal values: 16-20.
Transmit Signal Power
Measurement of output power Ideal Values Downstream:16-22, Upstream: 10-12.
Attenuation
Measurement of signal loss over circuit path. Attenuation is affected by loop distance, gauge of wire, gauge changes, bridge taps, and temperature changes. Values Max:60 Min:0 anything lower then 10 occurs at the Central Office. Ideal Values would be 20-30.
Bit Rates
Represents the rate in which the line last synch Minimum accepted value is 400.
