The FireBrick 6000 routers we use provide us with Continuous Quality Monitoring of every broadband circuit. This allows us to track the quality of each and every connection in great detail. The router itself produces the graphs in real time, and can also provide csv files with accurate data for each graph. |

|'''Regular drops repeating every day''' e.g. Central Heating causing drops. [[:File:Cqm-heating.png |View a week of these graphs]] Here there is interference as the central heating goes on, the drops are regular - twice a day, at the time the heating goes on. This actually highlighted a fault in the central heating for this customer as the graphs showed no drops for 2 days running! |
