But, surely you had the connection fee etc.

[MaximusPrime]

@William Grimsley,

connection fee was £35 so I thought it would have been worth it for an Engineer to check my line.

The problem is intermittent so it wasn't picked up but the drop outs are becoming more regular as time goes on

There's a big difference in 2Mb & 8Mb, 2Mb is junk, 8Mb is acceptable

Just after getting the cable from the post replaced

Any1 have analysis on the new performance?

We will need to review the circuit statistics over the next 24 hour period.

I've just had a sudden thought . . . Was it a network technician (PSTN) who replaced the final drop? Or was it a multi-skilled, broadband adept technician (one from Black Sheep's flock)? Basically, I am wondering if a "circuit recalc" has been performed.

@burakkucat,

I'm not sure what the Engineer's title was. He replaced the cable between both poles & installed a drop wire using 1 piece of cable so there'd be no joint, 100m approx, he used a higher gauge cable than the 1 he replaced. He ran an ethernet cable from the attic into the NTE to finish the connection. He then performed a DLM reset.

Highest max attainable I've ever had, lower line attenuation, upstream used to be locked at 14db SNR but its close to 6db now

Hopefully this will be the end of my trouble

[burakkucat]

Ah, thank you for providing those further details. After reading them, I can say that it appears you have had the services of a multi-skilled technician who has performed all the relevant broadband related tasks.   

[MaximusPrime]

@burakkucat,

yeah he seemed to know what he was doing

[NewtronStar]

And once G.INP is applied back on to your line it should look even better, and DLM reset had given you Interleaving no way would your line hold with fastpath instated for a month or even 2 days

Unfortunately something happened at 2317 hours . . .

@burakkucat,

sorry I switched the Linux box running DSL Stats off. I have a restless night if I leave it on in case something happens, no disconnects last night tho

[MaximusPrime]

Just after having an hour disconnection, graphs attached

Is it normal to have a Max Data Rate of 11Mb but yet the line be unreliable at a distance 2.8km from the cabinet?

Or have is there yet more problem with my line? or was this DLM?

The Senior Engineer who came out a while back believed my line would have "multiple problems"

[burakkucat]

The circuit has gone crazy! 

The Hlog plot is showing a metallic pathway defect, there are SES per hour being logged, DS CRC per minute in the thousands, DS FEC per minute in the hundreds of thousands, SNRM "all over the place" and nine resynchronisation events have been logged over the last 24 hours.

     

[MaximusPrime]

@burakkucat,

how can you tell there's a "metallic pathway defect" from looking at the HLog? What does it mean & why's it caused?

[burakkucat]

I've been "reading" Hlog plots for many years and so, at a glance, I can see that there is a problem.

Look at the image I've attached, below. See the segment of the curve to the right of the cursor? It should not look like that, it should be a smooth curve . . .

Unfortunately I am unable to say what is the cause and, thus, how to fix the defect.

[MaximusPrime]

@burakkucat,

HLog is the attenuation per tone? My HLog seems to have went back to normal

There seems to be a problem when it is raining.

There is a junction half way down the main cable.

Could the maintenance duct being filled with rain cause this?
