Noisy phone line when router connected

[#1]

Hi Luke,
As I rarely upload anything, I do not want to do anything that would reduce my download speed. So I think leave things as is, thanks.
I await with interest the update to my profile.
Thanks to you and Kevin for actioning this. Great service.

Hi Ralph,
I'm just another customer just like yourself - I cannot action anything - I can only analyse data user's post and pass an opinion on what might assist.

Actually, when the upstream is capped, it'll be the bottom half of the upstream section in the diagram that will be used, not the left half. There won't be any difference in the size of the gap between the upstream and downstream sections.
Uncapping the upstream shouldn't directly affect the downstream speed, but it could make the less stable. Even that shouldn't really affect the downstream speed, because the automated system that monitors line stability is capable of adjusting the stability of the upstream and downstream independently.

Today, the noisy line is back!
I have tested using BT Quietline having heard noise during phone calls today and there is noise present again.
As for the uncapping, despite the best efforts of others to explain the pros and cons, I do not feel I am knowledgeable enough to make the decision.
If it was advantageous to uncap, then why wouldn't Plusnet action it as a matter of course? Most users, including myself before this thread, would be unaware of the option.

Hi Ralph,
As noted before, uncapping not being in place is largely an administrative issue.  Asking you to decide is a matter of leaving you in control, it is though unlikely to have a negative impact.
As for the noise, it's back to faults an BTOR I'm afraid.  Intermittent faults are a right royal pain!

OK, can I ask for the US to be uncapped, please.
Here are the latest stats:-
1. Router Stats
                            D/s                U/s
Noise Margin  9.3dB              19.7dB
Speed                6335Kpbs    443Kpbs
Attenuation        41dB            21.2dB
2. BT Speedtest
Download        5.54Mbps        Acceptable range  2 - 7.15Mbps

3. Current Line Speed 8.1Mb

If it is of any significance, it is now raining here.

And now the router keeps dropping its connection.

Hi tich731,
Sorry to hear that you're now seeing the connection drops, I've attached the graph below to illustrate what we're seeing
<img src="http://community.plus.net/visualradius/generated/image14075021676646.png"/>
I've just run a couple of quick line tests on the telephone side of things and that returned no evident problems with that side of the service so I raised a broadband fault check (this was intrusive so could have caused a drop in connection). The results show that all tests passed however it did highlight some line loss degradation which is no doubt what you're seeing on your side now.
I understand that this may be covering old ground but before I pass this over to BT for them to investigate, can you confirm that you've tested the connection from the test socket directly with no extensions and all other devices removed from the phone line?
Let me know where we sit with the testing and I'll pick this up for you 
P.S. If you still want the upload uncapping just let me know and I'll get the modify placed for you.

Adam,
The line is quiet when plugged into the test socket. After the router powers up the line becomes noisy when the DSL light starts to flash.
These are the symptoms reported at the very beginning of this topic.
Yes, and please uncap the upload.

Adam,
This is right back where Ralph started.  Was the previous engineer a POTS or a BB engineer?

Ralph,
When you said the line is noisy again, I assumed (Stupid!) that you meant crackles etc., rather than the original issue of hearing "modem noises" on the line as implied in your last post.  Did I make an ass of myself there?
Has it been raining nearby during the last 48 hours?  Have you noticed any correlation of this issue with wet / dry weather?
Kevin

Kevin
The previous BT visit was by a POTS man not BB.
The noise on the line could be described as rustling, not crackles, but not strictly a modem sound.
Yes, in fact I did mention that it was raining around lunchtime today when the connection was dropped. This has also seemed to be the case for a couple of months.

Hi Ralph,
Apologies for not getting back to you sooner, I've had a problem with the test results as the broadband check is now showing a phone fault however the phone fault checks have highlighted nothing which is a little mystifying!
Third run on the broadband fault tests returned an all out failure of the copper so I'm going to raise this to BTW and see what a BB engineer can do for us. Hopefully we should see some movement on this shortly however I fear this is going to be something that requires another engineer visit to hunt for the cause.
With the fault now being raised I think we may need to hold off on modifying the service for the time being and lets see what we get when this comes back.
@Townman - Sorry for not getting back to answer these questions.

[#13]

Adam,
Don't worry - you've got a good result in the end.  This illustrates the difficulty with intermittent issue and the usefulness (or otherwise) of the automated test systems.
The fact that BTOR's own systems are confused about if there is or is not a fault should be a good angle for them to undertake a more through investigation.

But only if they take the unusual step of READING the notes first  ;D.    It really does make a huge difference if you get a good engineer  -  Coffee and biscuits have been known to convert engineer status for the better.
If you have 'spare' router it may be worthwhile trying it out.  I know it is unlikely, but I have had personal experience of a BT 205 showing similar problems.  Luckily in the state of early testing of the TG582 at the time so no sweat.  The problem was within the Router and NOT the PSU, so quite unusual.

@Jaggies - You're describing ADS2+ in theory and not the product we get from BT Wholesale. Additionally, My communications degree and four years experience provisioning and fixing broadband make me qualified to say "Uncapping your upload will affect your download"

Quote from: Jaggies

@ tich731 - Luke is incorrect to say that uncapping the upstream will affect your downstream - as they both use completely different frequencies, the only difference is that the unused "gap" between up and down is much smaller. There should be a diagram somewhere...

@Ralph - Connection isn't looking that great, I'll pick up once the engineer has attended.
