== CQM Graphs ==
===Lots of upload===
Here is an example of a CQM Graph with lots of upload traffic,
The example above show a line with occasional short uploads causing spikes in peak latency, and then a sustained upload starting at around 6pm and causing high latency (queue in the router). At 8pm there was more upload filling the link causing higher latency still and some loss (normal when the link is full). This is normal.It may cause the line to be slow. If you don't know what the traffic is, then you can do a [[Traffic Capture]] or ask Support to Help.
===Line dropped and speed changed===
[[File:CQM-speed-change.png|none|frame|line dropped and came back slower and with higher latency]]
This FTTC line dropped at 01:50, and came back within a minute or two, however, the speed has dropped (horizontal black line at the top) and also the latency (blue at bottom) has increased. There could be a fault here, but in this case we can clearly see that something has happened. If your line has changed in speed and is shown on the graphs, then diagnostics may find a fault, and the Support Team can help.
