This basically shows how much signal YOU are getting compared to noise. The higher this number is, the better. As this number goes down, it means there is more and more noise in the line.
Usually this is caused by bad shielding, R59 cabling, or bad connectors/wall plates. It's not easy to determine the location of interference.
Downstream interference means that you are getting a lot of noise around the frequency that your cable modem runs at. Troubleshoot this just like you would "fuzzy HIGH channels".
