What's going on with PN?

They then disappear back to the cabinet spend 3/4 of an hour filling in the paperwork just to make you think you've got a result, quickly remove the said "magic box" and disappear at 100mph.................................hey presto line speeds back to 0.35m download.

Sorry, john50, I wasn't aware of this.  I must be naive.  I will have to bear your experiences in mind.  Thanks for putting me right.

Thanks, artmo.  It is very encouraging.  I am hoping that I have the same sort of result with mine.  How long was it before you noticed the improvement in your speed?

[#3]

The improvement was immediate. As soon as BT identified and fixed the fault I was back to normal.

Hi artmo,
Thanks for your prompt response.  It appears mine has gone up by x2.2.  But still below what I had before 12/03.

@Adam,
Please respond to my « Reply #12 on 18/03/2011, 17:26 »
Thank you.

Hi Chandu, sure, I'm by no means claiming to be a faults expert, however I will get someone to check your account again and I'll do my best to address your questions in the meantime:

1) Line test from Master socket to Exchange, okay but he was not happy with line-noise.  Did the Speed Test with his Gadget.  Result Bismal.  Also, he had attached 20dB attenuator between master socket and his speed gadget (effectively increasing the line length) - NO Sync.  He also established through his gadget that the physical length of line from exchange to my master socket is about 4.6 Km.

Not the longest of lines but long enough, this may account for some of the issues with sync speeds you are having and unfortunately may be something you'd have to live with but rest assured we'll keep pushing for improvements as much as we can for you.

2) Changed the BT face Plate with current Openreach Face plate and removed Ring Wires and then carried out Speed Test.  Result much better speeds and  slight drop in Line-noise. Speeds constant at 3.5M/0.36M (down/up).

Good news

Quote

3) Checked speeds at the router connected to BT installed extension, with his speed gadget.  Result no loss in speed as compared with one achieved at master socket.  His comment - Very Good Quality of Cabling.  My response was: it ought to be as it was installed by BT at a hefty price.

So to clarify, are you saying the speeds were slower in the master socket?

Quote

4) After the Engineer left and while I was writing to inform the PN Tec guys, I had temporarily lost the sync.  Would be very interested to know why this happened.

We can't state why I'm afraid, this may happen from time to time and is nothing to worry about unless you lose synch repeatedly or for prolonged periods of time.

5) Just done a speed check using speedtest.net.  No improvement in speed.

Hang on, you said in your 2nd point that speeds had improved though, were you connected to the engineers test socket at this point?

Hi Adam,
Thank you for your help.  Now (as of yesterday evening) that the tech guys have now carried out an SNR reset on my line which has reset the sync speed and also they have removed the banding and speed limitations which had been put in place on my line, the speeds have improved considerably. I shall monitor my line over the next 72 hours.
The my broadband speed tests for today (22/03/2011) look very good and they are:
Today 22:47 2440 kbps (305kB/s) 382 kbps (47.8kB/s)
Today 12:53 2437 kbps (305kB/s) 340 kbps (42.5kB/s)
So, Adam, thank you and rest of the Tech Team.  I have my fingers crossed for the situation to remain stable.  I sincerely believe the issue appears now to be sorted.  Next few days will be crucial.
Well done and, I must say, it has been a fantastic service regardless of what other users say.

Thanks a lot Chandu

Hi Adam,
Thanks, but did I speak too soon?  My upload speeds have started to drop AGAIN.
Can any one explain why this happens?

I wish it were that easy could you run some speed tests for us please http://www.speedtester.bt.com/ also can you advise what you were doing? i.e sending mail, using FTP etc.

Hi Adam,
Thanks for your prompt response.  I was only using the squirrelmail and going through the forum.  I haven't done uploading.  But as I was asked by CSC to keep an eye on the speeds, I had done both bt speed tests and the my broadband speed tests.  I  am copying both results below, if it helps:
BT speed Test -
Results Image not loaded
Test1 comprises of two tests
1. Best Effort Test: -provides background information.
Download Speed
2273 Kbps

0 Kbps 4000 Kbps
Max Achievable Speed
Download speedachieved during the test was - 2273 Kbps
For your connection, the acceptable range of speedsis 1200-4000 Kbps.
Additional Information:
Your DSL Connection Rate :3180 Kbps(DOWN-STREAM), 240 Kbps(UP-STREAM)
IP Profile for your line is - 2500 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 13.92:23.07:63.03 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.
The results of this test will vary depending on the way your ISP has decided to use these traffic classes.
2. Upstream Test: -provides background information.
Upload Speed
183 Kbps

0 Kbps 240 Kbps
Max Achievable Speed
Upload speed achieved during the test was - 183 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 240 Kbps
The My Broadband Speed Tests for last few days:
Today 00:27 2280 kbps (285kB/s) 201 kbps (25.1kB/s) Share
Yesterday 22:52 2272 kbps (284kB/s) 199 kbps (24.9kB/s) Share
Yesterday 14:21 2281 kbps (285kB/s) 197 kbps (24.6kB/s) Share

Tuesday 12:53 2437 kbps (305kB/s) 340 kbps (42.5kB/s)
From the above you will notice that though the download speeds have not dropped very significantly but the upload speeds have dropped quit a bit.  Also the IP profile has dropped.  I hope this helps to diagnose the problem. 

[#12]

Sorry, Adam, I should have also added that the scs have already been informed of the above.

Hi chandu,
If you let me know when you update your ticket to say you're in the test socket then I will get the faults guys to retest it for you.

[#14]

Welcome back JoJo.  I hope you had good break.  I have already updated my ticket and also explained the reason for delay.  Please check the ticket for the reasons. If you need the ticket number please let me know.
Incidentally, when the router is connected to the test socket: 1) Will I be able to use my phone?, 2) how long do I need to leave the router in the test socket? and 3) I assume that the router will have to connect thru filter to the test socket,  am I correct?
Thank you very much and I await your response.

[#15]

Hi chandu,
Thank you.
Yes, I saw the ticket. In answer to your questions...
1) Yes, if you plug a filter into the test socket there are two inputs in the filter, one for the phone and one for ADSL
2) As long as possible, but at least for a couple of days so we can see how the line performs.
3) Yes, you will need to plug a filter into the test socket.
Hope that helps.
Jojo
