- 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.
- The following example represents a normal line test for comparison purposes.
