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.

Here is another, an FTTC line filling the up link whilst doing a backup (
[[File:CQM-FTTC-upload.png|none|frame|Lots of upload in the morning - a backup without any traffic shaping on the client end]]
This line is doing a large backup from just before 6am. The dark red horizontal line shows the traffic, during this time there is lots of packet loss (red) and the light blue at the bottom is showing high latency. So, whilst the backup is happening the line has about 50% packet loss and around

This line does have a fault. It is dropping sync throughout the day. In this type of case, go through the usual checks, and AAISP will report a fault, which will probably need a BT SFI
===Only Dropping during the day===

(Probably not an ADSL Fault.) If a line is dropping during the day, and maybe just Monday to Friday, then it's probably not going to be an upstream problem. This could be caused by interference

===Faulty Card in a TalkTalk LTS===

Here we have three days of graphs, you can see packet loss starting at around 2:50AM, which then gets worse two days later and is then fixed.
This was a faulty line card in a TalkTalk LTS - Only a small number of circuits were affected with packetloss due to this though.
The time ties in with logs from TalkTalk's LTS:

From 9AM on day 3, the interface that we have with TalkTalk started reporting input discards.

The faulty line card was taken out of service, and the packet loss was no longer.
