No, i think he is saying what he has always said: Read this!

In reply to a post by matthewcl375:
Jussst had a re-sync here's what's showing on the event log:


12:57:14, 02 Apr. (547313.600000) DSL is up
12:57:11, 02 Apr. (547310.950000) DSL noise margin: 5.90 dB upstream, 4.90 dB downstream
12:57:10, 02 Apr. (547309.870000) DSL line rate: 1223 Kbps upstream, 19000 Kbps downstream


And stats:


ADSL Line Status

Connection Information

Line state: Connected
Connection time: 0 days, 00:32:31
Downstream: 18.56 Mbps
Upstream: 1.195 Mbps

ADSL Settings

VPI/VCI: 0/38
Type: PPPoA
Modulation: G.992.5 Annex A
Latency type: Fast
Noise margin (Down/Up): 4.8 dB / 5.9 dB
Line attenuation (Down/Up): 6.2 dB / 3.3 dB
Output power (Down/Up): 20.1 dBm / 12.3 dBm
FEC Events (Down/Up): 0 / 0
CRC Events (Down/Up): 1 / 0
Loss of Framing (Local/Remote): 0 / 0
Loss of Signal (Local/Remote): 0 / 0
Loss of Power (Local/Remote): 0 / 0
HEC Events (Down/Up): 2 / 0
Error Seconds (Local/Remote): 74 / 127


Does this mean I'm now on a 3db Target NM?


For comparison purposes I don't know whether this helps, but since we both appear to be on lines that are close to the Exchange, these are my current figures (I was transferred to BT just 2 days ago):-


ADSL Line Status
Connection Information
Line state: Connected
Connection time: 0 days, 09:38:07
Downstream: 21.31 Mbps

Output power (Down/Up): 20.0 dBm / 11.5 dBm

Thanks, I wasn't around smile.

There is a bit of doubt as to whether the figure of 80% in that link should be 70%. (70% is what I originally had there but later it seemed it had been changed to 80%, now there is doubt about that).

I think the FTR is largely irrelevant in this case given the original 9dB margin. If I had been correct in my recollection of it starting at 15dB I feel it would have been important.

You were remembering, perhaps, OP's original Tesco connection on 20CN IPStream.

Very possibly smile. Either that or another current/very recent thread.

@johnjburness your stats are slightly better than mine in terms of sync, hmm I seem to have isolated most causes of reduced sync so all I can put it down to must be something to do with the exchange or the local loop

To everyone else, is it normal for HTTP file servers to 'throttle' your down speed? What I mean by this is, I often download via Bit Torrent, and I see speeds of up to 1.9MBps. However on HTTP, I normally start off at full speed or close to it, but over time the speed goes down.

For example, I am downloading from Apple right now. I started off at 1.7MBps but now only at 750KBps :/

@johnjburness ....
It would be preferable to click the Reply button against the post you are replying to in future smile. For a starter the system then labels it as such, and there's no need for the" @someone" in the post.

You may not be aware there is an option in your forum settings to get an email sent when someone replies to you. So I could easily have got an email about this if I had that set - which would have been annoying, and if he relied on receiving an email to tell him he had a reply he wouldn't have got it.

This thread's getting pretty long, and I don't have much more to add, my line seems to be doing quite well:


ADSL Line Status

Connection Information

Line state: Connected
Connection time: 5 days, 13:35:21
Downstream: 18.56 Mbps
Upstream: 1.195 Mbps

ADSL Settings

VPI/VCI: 0/38
Type: PPPoA
Modulation: G.992.5 Annex A
Latency type: Fast
Noise margin (Down/Up): 4.6 dB / 5.7 dB
Line attenuation (Down/Up): 6.2 dB / 3.3 dB

Going to close this thread, unless anyone sees anything else that I could do or any problem with the stats smile
