High attenuation on short line

Question

I'm getting what seems to be quite a high attenuation on what should be quite a short line, router stats below.
Hub is connected to the socket after the master but it makes little difference when connected to the test socket. I've tried the quiet line test and there's a little bit of noise, more so after the BB was activated
I'd estimate I'm no more than 1KM from the exchange (I can see it out of my window!) 
What do you guys think? Worth investigating or not?

That reports almost 4KM, which is probably quite a bit out. Could it indicate a bad connection somewhere maybe?
Possibly it could however, have you tried to replace your Microfilters?
When I had the problem with my connection (here), the line noise was terrible and I could clearly hear the modem syncing when connecting. Had researched it and found out it could be caused by a HR (High Resistance) fault. 1 month later and having a new lead-in installed, the line was fixed.
Obviously it probably isn't the same scenario but one way to find out is; Does your connection disconnect a lot? I can see your connection has a high uptime so I'm guessing it probably doesn't.
One way I found to diagnose a HR fault by myself was to leave the modem disconnected overnight and in the morning before turning on the modem again, listen for any noise on the line. In my case the Noise seemed to disappear mostly after leaving the modem off for a period of time, despite being diagnosed as a very bad HR fault in the buried Tee which later which turned out to be correct.
The DSL and Phone Signals are on different frequencies and therefore you shouldn't be able to hear the DSL signal on the phone. It means somewhere the DSL signals are leaking into the phone which could be the microfilter, Line Card or a HR fault. Could also be caused by a dodgy phone or Wireless phone.
Any noise on the line as John said shouldn't happen.
Microfilters are the best place to start off with first though if you haven't tried replacing it.
