What do you think is wrong?

[psp83]

Well my connection has been fine and stable for a while now..

Until the last few days.

I have been getting quite a few resyncs throu the day and night.

This morning is quite bad.

My noise margin is all over the place and i've just got disconnected and reconnected at
Connection Speed    608 kbps    448 kbps
Line Attenuation    35 db       12.5 db
Noise Margin       12 db       16 db

I then reboot the router. This then connected at 6080 kbps with margin at 12 and after a few secs my sync drops and connects lower again.

Connection Speed    3616 kbps    448 kbps
Line Attenuation    39 db       12.5 db
Noise Margin       12 db       26 db

My line is doing my head in

Have you done all the usual things, Paul, to eliminate your own wiring? If so, have a word with support and get BT on the case, that line is flapping badly.

[Sebby]

It sounds like there are some serious surges of noise. Have you tried the test socket?

[psp83]

not tried test socket yet, will do that later but i've tried all the rest.. not much i can try thou tbh..

Its a filtered faceplate, a shielded rj11 goes from the faceplate to the router (1.5m cable) and the pc's are connected with ethernet.

So its can only be a dodgy router, faceplate or a bt problem.

[Sebby]

It's likely, in that case, that it's a BT problem.

[psp83]

support can't find no faults. they've passed it onto BT now, waiting for an update.

Connection Speed      2080 kbps      448 kbps
Line Attenuation        38 db            12.5 db
Noise Margin             11 db            23 db

Thats my current stats, i've been getting 6500 kbps at 12 SNR with no problems for ages and now it wont go above 3000 kbps

[psp83]

Also noticed that the Line Attenuation is changing with every resync, its never changed before since i went onto max bb. always been at 39.

Also upstream noise margin is going up and down and that used to be stable and never moved from 29.

[Sebby]

Fluctuating upstream SNRM is a real sign of very strange noise activity.

[Rik]

That sync speed for an attenuation of just 38db suggests major noise, Paul. Even I manage 3520 on a 56.8db line.

[Glenn]

Paul, that sounds like the same type of issues I am having, yesterday support logged a case with BT again.

[psp83]

Still waiting to hear back from support..

Its becoming a joke now and my SNR has been pushed up to 15 from 12 now

[Sebby]

Unfortunately, in a situation like this where the fault lies with BT in one way or another, IDNet's hands will be tied.

[Rik]

Its becoming a joke now and my SNR has been pushed up to 15 from 12 now

That says your line is flapping, Paul.

[psp83]

I picked the phone up before i went to work this morning and it was very noisy.. sign of a line fault somewhere?

[Lance]

It certainly is - but report it to BT voice services.

[Rik]

And don't mention ADSL!

[psp83]

i'll double check the filter first when i get home where sky extensions plug into the filter and the phone plugs into the sky splitter, if its still noisy with the phone plugged straight into the wall socket then i'll contact BT voice.

whats the number for fault checking again?

[Lance]

The quiet line test is 17070 - option 2 I think

[Rik]

It is.

[psp83]

Theres no fault on the line.

i disconnected everything from the wall socket, plugged the router back in then plugged the phone in, The phone was hissing and popping. I then disconnected the router and the phone went clear. Connected the router again and the noise was back.

You can also hear a slight noise in the background, just like the old dialup modems made when connecting.

Connection Speed   1568 kbps   448 kbps
Line Attenuation      37 db         12.5 db
Noise Margin          13 db         23 db

Connection Speed   3072 kbps   448 kbps
Line Attenuation      39 db        12.5 db
Noise Margin           8 db        27 db

Connection Speed   1216 kbps   448 kbps
Line Attenuation      36 db         12.5 db
Noise Margin          15 db          25 db

Connection Speed   5728 kbps   448 kbps
Line Attenuation      39 db         12.5 db
Noise Margin          15 db          26 db

Line is still all over the place. Don't know what to do now 

[Sebby]

To me, that sounds like a faulty filter (though it could be the router). Do you have another filter to try?

[Rik]

Buy a new filter? The symptoms are classic for a filter failure.

[psp83]

The faceplate is filtered so i will take it of and plug a normal filter into the test socket.. I have 7 normal filters to try, if none of them fix the problem what should i do next?

[Rik]

Try doubling them, Paul. If you still have a problem, you'll need an SFI engineer to resolve it.

[Sebby]

Or it could be the router...
