Yes, it is very remarkable. As you guessed the the DLM runs my noise margin at 3db, hence the excellent speed. This is fine during the summer months and light evenings, but at this time of year can lead to the odd drop in early evening when SNR can go below 1.0. However, I can put up with that given the excellent (stable) speeds during the day. Here's the full stats right now.

The upstream is pegged at 888 because my line is running with Interleave on. I understand that is what limits the u/s rate to that figure. Not bothered, it's a near 100% increase over 448!

I think a 'maximum' upstream sync speed of 888kbps often associates with interleaving on. The equivalent of 7616kbps downstream often seen on ADSLmax with interleaving on.

Hmmm .

I believe you, but I wonder if this is specific to Plusnet. There are many BT Wholesale-using ISPs where this is not the case.

In the same way as they put the initial 440 cap on it that no-one else does.

The whole point of Interleaving is to allow higher connection an throughput on less than perfect lines. So to cap it at a low speed is perverse. That would achieve stability without interleaving.

I haven't quite sussed out Orange's BT White Label Up speeds, but I've noticed that it often runs at 888 Interleaved. I think it has also run up to 1.3 Meg but I can't be sure. It certainly has on Fast Path.

I'm not sure how this would just be specific to us - it should be the same for all BTW based ISPs as it's all the same type of order?
