Line test

psp83 · Mar 28, 2011, 14:29:43

Hey,

I've been having problems with my phone line lately and just wondering whats the best way to do a line test with BT.

Email that I sent to support.

QuoteI've been getting a lot of problems lately with the noise margin suddenly dropping and then I can't load any websites until the noise margin comes back up (normally minutes but has lasted much longer). This happens at random times. I normally reboot the router when this happens to get a lower sync to push the noise margin higher but the router normally re-syncs at the same rate.

Here's a link to my think broadband graph last night : http://www.thinkbroadband.com/ping/share-large/233664edd513d8ac2a35f942ca028a85-28-03-2011.png

I have swapped over to a new router/filter as well just in case that was the problem.

Quiet line test is best to start with, dial 17070 and select option 2, you should only hear a background hum.

Are you connected to the test socket, Paul? What does a BT speed test reveal?

psp83 · Mar 28, 2011, 20:40:53

I have tried the test socket and no different, BT speed test hasn't worked for me for ages.

Will try it in a mo and post the results.

Would a dodgy street light cause noise problems?

Over the road from me (not near my line) we has a street light that keeps going off and on.

Down :

Download speedachieved during the test was - 7104 Kbps
For your connection, the acceptable range of speedsis 2000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8440 Kbps(DOWN-STREAM), 896 Kbps(UP-STREAM)
IP Profile for your line is - 6500 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 18.2:21.93:59.87 (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.

Up :

Upload speed achieved during the test was - 739 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 896 Kbps

Just done the test, had a few pops and hissing noise, not as bad as it has been.

is the BT tester playing silly again as your result shows a higher speed than your profile, didnt think this was possible and I have also had similar results lately so just took it as usual BT test naughty ness

You can tell when my noise margin plays up.. the red spikes are exactly at the time everything stops working and my noise margin all over the place.

What can I do next ? as this is becoming really annoying now.

Have you had a reply from support yet? It looks like bursts of noise or BT messing about.

psp83 · Mar 29, 2011, 08:30:37

Yeah, James replied yesterday which is why I posted here about a line test.

QuoteNoise on the line will effect the broadband service greatly. You will need a copper test carried out and the noise problem will need to be resolved as a priority. Please contact your phone line provider to have the test the line for you.

Quiet line test last night wasn't that bad, it gets bad when the noise on the router drops down but that happens at random times so can't really test it when it happens.

Is this link any use then , I guess you'll need to use your mobile dongle as well.

I've done that test through the BT site, came back no faults found.
