RE: 33dB noise on d'stream

> whats this mean??


A bit more info would help.
Where is this figure from?

I would hazard a guess that it could be 33db Signal to Noise Ratio measured on the downstream signal but without knowing where the information is from then its just that, a guess.

The figures you have posted show a pretty good line with a decent signal to noise ratio.
They mean that in the worst case your signal is 21dbs above the noise level or in real terms over 100 times stronger than the noise.
attenuation levels for up and down are well within the limits needed for 512k ADSL.

From the ADSL Guide site
Line Loss (They need to ensure your line has suitable quality for ADSL), You need a line loss of no more than 41db for 1Mbps & 2Mbps products, 60dB for 512kbps products.


The above shows that your line should be good for the 2 meg version.
Why you are getting the cutting off I don't know.
Have you tried the fault finding guide from the Tutorials section of the forums?
In particular what happens if you connect directly to the master socket with no other apparatus connected to your line?

Many modems and routers have this function built in and will show you the line loss and noise figures by going into the menu.

Hi, would I be able to get line reading details on my line via a Whoosh test although I dont have ADSL?

No - Unloess you allready have ADSL, you can't have a whoosh test performed.

Once you have ADSL, only the ISP providing your line can perform the whoosh test.
