If you cant hear anything then that indicates the line is fine.

Crackling or hissing indicates a problem.


--------------
I'm still puzzling over the LoS increase.

As ezzer says you may have to bite the dust on this one and contact your ISP and ask them to investigate why your line which has a 26dB attenuation and should therefore be capable of near 8Mb is being limited to 512 kb. :/

not with the quiet line test, all this has is a basic 50v running down the line with no pstn (voice) signal/noise transmitted apart from the "quiet line test" every 30-40 seconds or whatever time period it is.

If you hear nothing, then this is good. it's common to hear a faint low hum which is mains electric noise picked up. a slow click or heart beat noise is usually electric animal enclosure fencing. any other noise, try another phone (if your using a cordless phone, this dosn't mean another slave phone on the same cordless group.) if the same noise is there then there may be an issue on your line

By the way KITZ the 17070 test is striclty speaking for openreach enginners only. if you ever see an enginner repeatedly typing a few numbers on their butt phone & muttering under their breath it's because the tester is too busy (often because too many people know about it)

But trying for more detailed tests (opt3,1,2) it asks for a mobile or pin number, so I presume BT have made this area 'engineers only' .... they could surely also protect the quiet line test if they wanted to. I wonder if I put my own mobile number in would the advanced tests work ?

I would be wary of using any test other than the quiet line test. I'm sure I've read somewhere that BT can get quite uppity about people trying to use the other tests, but tolerate use of the quiet line test.

well these are the result i have

Those figures from the estimator are excellent. Your line is expected to be capable of the highest speed which is available on ADSL Max (8128 kbps), whereas you're actually only getting 576 kbps with an enormous noise margin.

Actually your latest router stats do suggest that you've been put on a fixed speed connection in error. The up/down figures (288/576) are exactly what you would get on a fixed half meg connection, so I suggest that this should be what you put to the call centre.

Good luck! :)

 I dont think its BT (your ISP) that has done this.
I strongly suspect you are on Max (why else would there have been a few recorded FEC errors last night) .... and been rate limited by the DLM if your line has been detected as a "cronic flapper" at some point.

What I do think is interesting is within the past few months or so Ive seen a couple of instances of lines which have been DLM rate limited which  generally should in theory be very good lines.

If youre wondering what I'm talking about then having a read through this thread which shows it all unravelling.  On page 2 you will see that the ISP was even stumped at one point, and werent even aware of the fact that it had been capped by BT Wholesales DLM, then partway down that page you will see what caused the incident.  Despite the electrical fault being rectified since that time the poster found himself rate limited.


What I would do is contact your ISP and tell them:-

~ Your line stats of Attenuation 27dB and SNR Margin of 30.5dB indicate that your line should be capable of the full 8Mb.
~ It is evident that your line is being rate limited at some point to 576Kbps.

You need to stress to the ISP that you suspect it could be some sort of restriction placed by BTw's Dynamic Line Management system that is stopping you attain sync any higher than 576kbps...  and could they please check to see if your account has been incorrectly capped by the BTw system.
