My internet connecction has been much worse than normal recently and the phone has no dial tone and is engaged when called. The line stats are currently as follows:

It previously had an attenuation of around 31dB (or something) and a downstream attainable rate around 8mbps. The phone hasn't worked for about a week. The problem seems to be intermittent as it also was happening a couple of weeks ago but fixed itself somehow. It may just be just coincidental but this most recent case started during heavy rain one night.

Edit: Sorry, that table turned into a complete mess.
