My ADSL2+ router gives me the following statistics:

SNR Margin: 16.8

Line Attenuation: 25.0

Data Rate: 8192 kbps

Max Rate: 16972 kbps

I don't quite understand Data Rate and Max Rate? Is Data Rate the current speed I have (with overhead), and Max Rate the max speed my telephone line can handle (based on distance from DSLAM, quality of splitter, etc.)?

Any help would be greatly appreciated
