Quiet Line Test seems fine.
The user noticed low speeds from day one.
The connection was capped/banded at 15 Mb when 24/7 monitoring commenced 4th June.
DLM was reset 6th June at 40 Mbps, but US sync speed has remained unusually low throughout.
That didn't last for long though.
The D-side connection is approximately 820m in length.

Some of those resyncs reported Retrain Reason 0 & some reported Retrain Reason 2.
Only one of them was user initiated.
The 2Wire router that has been used for a while was replaced by the original HH3 at 17:37 yesterday.
The connection/DLM didn't seem too happy about it though.
It now seems to be banded at 30 Mbps.
