Pulse8 (they use TTB)

A different BRAS wouldnt improve my SNR tho while still maintaining the same sync speed i would have thought

Netgear block the telnet access needed to obtain the full DSL stats.

There's a post on the kitz forum showing how to enable it if you're technical enough

https://forum.kitz.co.uk/index.php/topic,15306.msg28...

It's a Broadcom chipset so very detailed stats available over telnet.

It's currently showing you the noise margin for each of the downstream/upstream bands and not the lines overall noise margin.

Thanks will look into that.

Oddly my noise margin increases during the night by 0.5db. Which is strange as noise margin usually decreases slightly at night

No, but it could affect the routing of your traffic, which could affect your measured upload throughput.

Note that an *improved* SNR implies a *lower* sync speed, if the line conditions are the same. This might be an artefact of how it's measured, or it could be an environmental change (e.g. a source of interference has gone away)

In the old days on ADSL noise was often seen to increase at night. Kitz have an article on this that states

During the hours of darkness there is increased radio frequency interference in the atmosphere which all broadband lines will pick up to some extent. During the evening/night the SNR trace becomes jittery and the SNR Margin falls, but the line will recover the next morning.

Yea which seems odds mine is the opposite. I get a better SNR at night

It's very difficult to predict interference levels... too close to a radio transmitter and it will probably increase at night, but if that transmitter is a taxi firm it may get worse during the day. Too close to the wrong sort of factory (eg one that does a lot of arc welding) and it may get worse during the day, and vary depending whether they work shifts or not. All sorts of possibilities, you just have to live with what you've got.

My line goes through a small industrial estate and was quietist between about 11am and 1pm (lunch hour?), so that's when I tried to do forced re-syncs if I wanted to try for a better sync speed . Even then it didn't always work

Well syncing at 9997 kbps i was expecting maybe 7Mbps at least

Maybe im wrong?

9997kbps is the equivalent of 10Mbps, so that's actually higher than 7Mbps.
If this was 7000kbps then that would be 7Mbps.

Now if you're saying that you're only getting 7Mbps in a speed test with a sync speed of 10Mbps that's pretty normal too. Not all speed test servers will give you exactly the same upload speed as what your router is syncing to. This will also apply to download speeds as well.

I believe there is always some speed lost from what your router syncs at due to overheads etc

So 1 week since i got FTTC installed

Ive had 3 disconnects during that time (1 was a power cut so not counting that). So im averaging 2-2.5 days synced before a resync

Both resyncs have happened during the night - 1 at 1.30am the other last night at 12.20am. Could that be the DLM?

The odd thing is the resync syncs at the same speed (40000kbps/9999 kbps) so getting full speeds for my service and the pings improved so no interleaving. The down snr gone from 10db to around 12.5-13db at the same sync speed. Upstream remained roughly the same at 10db give or take.

The disconnect last night lastes 5 mins which suggests something more than DLM just resyncing the line.

Guess i need to use the Netgear telnet hack to see my full stats
