I am gonna bring my JDSU home tomorrow and check the sync speed and other values and it will also show the line length. Will post info from tester tomorrow.
Ran some checks with my trustee JDSU.....
Cct info is
Anx A ATU-R
Estimated Line length... 2.9Km
Actual upstream... 448k downstream... 4860k
Noise Margin up... 19dB down... 6.5dB
Line Atten up... 31dB down... 47dB
Signal Atten up... 31dB down... 35dB
Connect Methd... fast / fast
In the cct info it does not show ADSL or ADSL2+ it shows G.DMT, so I believe I am on the max version (new type 20CN) which does only ouput 8mb from exchange. It begs the question- is there a particular reason why they would not put me onto the same ADSL2+ (up to 20mb) service I was on before moving which was on the same exchange with approx the same line length to both houses over same type of copper pairs via one PCP ?
I have given up trying to use BBC iPlayer as it just buffers all the time and the other night I tried to watch an episode of Justified on BT Vision on demand, this also buffered a good few times but not as bad as iPlayer. I have been watching Justified at my previous address before moving and it always streamed OK. I have not yet tried a movie !
with your 47db line attenuation you connection speed is not going to be as good as previous home and probably about 5.5mb on adslmax or possibly 6.5mb on adsl2
Already done that, results are on 1st page here. Since it was started on the 25th Feb it has been up and down like a yo-yo from lowest at 2mb to highest at 5.5mb and the JDSU sync test shows many CRC errors and loads of FEC errors after only 15mins. The line pair quality tests OK tho' and within acceptable limits for a good BB connection. As I type here the hub shows in sync at 3.1mb compared to the 4mb plus earier this eveing when I posted.
