Intermittent broadband faults

Hoping for some advice on intermittent broadband faults on my business line.

 

Firstly some basics,

 

No internal extensions, filtered faceplate on master socket used, several tried along with line filter and test socket with no difference, shielded ADSL cable to router (2700HGV). 300m of overhead, checked recently dropwire 12 (single 0.9mm) cable (I have two of these)

 

At times, especially during bad weather the line will drop, this may result if I am lucky at a connection back in the same range, it may result in a drop of several IP profiles or it may result in a drop even further then a connection is made, all the way down to the 135 profile.

 

Current training history is as follows (idle_requests are me using the link test to get the speed back up again after a drop and once the noise margin is higher than the target margin)

You can see that in this occassion this line has not dropped all that much but the second line I have shows the effect more (all down to which second the reconnect is made), when it lost sync at the same time it went down to the 135kbs profile range but just after syncing it's noise margin shot up from 6db to 22db
