===Faulty Card in a TalkTalk LTS===
[[File:Cqm-faulty-lts-card.png|none|200px|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.
