Help reading Line stats

Could someone with the knowledge look at my screenshot of my stats and tell me if this is good or bad... I'm a bit worried about the amount of "errors" it is claiming.

This is a connection which is freshly installed today, so I know it might get better/worse over time, just wondering if the stats are ok for now and what numbers I should be aiming for.

Just to add this is a Plusnet Home connection on 80/20 Mbps service.

About 400m from the green box.

The errors should reduce when interleaving is applied in a couple of days.

Downstream is a bit low for a 14 dB line - I would expect it in the 70s however with 6dB SNR it suggest there is a fair bit of noise potentially from cross talk. Upstream is about where I would expect it to be.

Thank you for replying.

I have no idea about these things which is good that others do

I have heard of interleaving before, I also remember that I have always been told I am meant to wait around 10days for the line to "settle" which I assume is what this interleaving will be then.

there is a few other things that run nearish to the cable, so maybe it is that which is causing the noise, i will have a look around tomorrow when its bright and see if its something outside or inside.

Seems a bit low as troublegum has mentioned.

Do you see any difference if you connect to the test socket?

Could be a lot of things - fridge, freezer, plasma TV, central heating, heat pump, generator, LED street lamps, general factory type machinery ...

Not sure if it will work with your modem/hub, but get a copy of DSLStats and see it it does, that can give some very good information.

Agreed.

My guess is this not connected at the NTE, or there�s extension wiring present (causing a bridge tap)

Not sure what a NTE is and even googling gives me its either a big rack mountable piece of equipment that I know I don't have or its a BT Socket.

I do have the "new" socket and there is no extensions on this line at all, not even a phone.
the line is purely for data.

Not sure if i should play around with disconnecting and reconnecting to the test socket incase it affects the profile? or is this a myth.

there is a really old freezer that is close enough to be a problem, so I might try turning that off for a bit and seeing if there is any change.

The other thing I was thinking is that it might be the cable that runs from the socket to the router, as that is very thin and looks quite cheap.

Turn the freezer off for a couple of hours - just do not open it and it will be fine. Do the same with any other devices close by - including fluorescent or LED lights.

Then, start watching the ATTAINABLE or MAX rates not the sync and see how it changes.

It has now been 7days since the install, I have not really noticed any increase or decrease in speeds or any of the figures.

I did how ever find I can login to my routers command line interface and it shows a bit more information, it does also show that interleaving is still off, should this be on by now ?

I am also not sure if everything is correct, as there is "Bit Swap" and "SRA" Options in the DSL settings page and both are enabled.

Here is the info from the router:

It seems that the rates have not changed much at all, I have got a new router being delivered in a few days so maybe that will be better than what I have at the moment.

So far I still dont have any interleaving on and I still have no idea on these SRA and Bit Swap settings even after googling and reading about it, all I got from it was that Bit Swapping will help if a channel is too busy and SRA is meant to help with noise on the line i think.

I believe that Bit Swapping has been present on all UK xDSL systems since Day 1. What it does is if a noise source takes out some of the capability of a particular frequency/bin at some point after the connection was made, lowering the number of usable bits allocated to/provided by the bin, then unused space on another frequency can be used instead to maintain the sync speed. Bits are swapped from one frequency/bin to another.

That does require there still to be available spare space.

SRA, Seamless Rate Adapt(at)ion, allows the modems at each end to adjust the connection speed without needing to disconnect and re-sync when noise gets too high for the current sync to be maintained.

It has been experimented with in the UK in the past, Be Broadband being one ISP that had a go, but as far as I know it is not currently used in the UK. Openreach on FTTC and BT Wholesale on ADSLx have not implemented it.

You need Bit-Swapping ON. SRA doesn't really matter at the moment but I recommend leaving it ON. It does no harm.

Thank you for explaining that.

It does seem an advantage to just leave on then.

Would be nice if it was supported more though, it does seem quite useful, well to me it does.

Not had any drops though apart from when I have caused them so hopefully this connection has stabilised and I can rely on it. well until the new router comes.. then it's going to drop and most likely think there is an issue and go really really slow... but we shall see.

I also wonder if that is a big cause of peoples issues with speed, as most people instantly think to just restart their router if it doesn't seem to be working correctly and that would cause a drop and if it doesn't pick up speed again they are more likely to try again and it might be seen as a bad line...
