Best I have seen to date, very nice, what was your stats before? and what was your estimate?.

Previous stats were:

The BT speed estimate was 31.6 / 7.5 (wrong as usual).

my estimate was 32.5 and 8.5

my attainable rate has dropped to high 46 - 47 mark depending on the day, but my cab is getting very populated now. Used to be 48 to 49 mark.

I'm hoping for full 80/20 sync when 17a is enabled on my line.

I think I just answered my own question, checked my stats and been upgraded.

You must be with in spitting distance of your green cab with stats like that? I know where my cab is but the line I have to it must be ancient!

Very nice, indeed! Does your D-side consist of a cable from the back of the NTE5/A straight through the wall and into the PCP on the other side?

My cab is about 110m behind the house in the next street but the cable run is longer. I paced it out at around 200m following the likely cable run. My stats are similar to lockyatlrg's and his line is 300m, so I guess that mine is similar.

yeah my cab is about 200 meters by road, but line length is 300, but it's all underground 0.5 copper and this estate is 4 years old

I did have really poor stats for a while with drops outs etc, I had a lift and shift done as the post I was on was faulty.

they did a length test on the JDSU and it come back at just shy of 300 meters.

I'm chuffed with my stats and leaves plenty of room for the 80/20 product.

Erm, sed 's/post/port/', I guess.

Dunno, bt man came to my house did a load of tests on the pair, pair came back 100% got a call from openreach for new ties or something along them lines, he went to the cab and came back and my line stats where back to very good levels and all was well
