Very similar to the first line!

53mbit sync is the highest I've seen from either line though. US2 still decimated.

As you say - both lines are very similar.

Ask yourself, what is the chance of both lines having the same faults or corroded joints? The answer is very little.

There are two common factors:

Attenuation - nothing you can do about that without moving house! With 16.5dB down, you are around 400-450m from the cabinet - does that sound about right? If it is then you should have a full 20Mbps UP or at least close

Noise - if there is an external noise source causing problems at the top end, it would affect both lines AND you are seeing similar results on both. What else is connected to the lines? Have you tried it with everything else in the house powered OFF? What about neighbours? What are they seeing?


Edit to add:

Look at the notch centred around tone 1025 - what is the cause of that?

Then at the end of D2 your SNR per tone is down at 20 to 22dB, I am getting 33dB

Yep, 400-450m sounds about right.

Here is an album from before the 2nd line install, showing the old drop cable, and the long run to the pole. As you can see, it crosses a few neighbours gardens, so there could be anything happening there really!

Going back to your last thread where you had old drop wire - you had te same issue of upstream then. Changing drop-wire is unlikely to do anything more.

To me, everything points towards noise, and going through gardens as yours does - it could be picking up anything!

Here's hoping FTTPoD gets re-released at a more reasonable price point I guess!
