52dB Line Noise

I have been given a 52dB line noise result, would anyone even attempt to try the 2mb service with this result? Or even the 1mb?

Thanks.

Dont confuse noise with loss.

The 52db should be the signal to noise ratio of your line and here the bigger the number the better.
the figure you quote means that the noise is 52db LOWER than the signal which is good.

More important is the LOSS result and if this figure is above 55db then that does mean that the signal is getting too week by the time it reaches your home.

RE: 52dB Line Noise

I think I have got it wrong, this is what I got:

A test on your lives gives a line loss of 52dB which is over the 41dB limit for faster ADSL.

So does this mean, I might be okay, or I might not be okay?

Thanks again.

Ok on the corrected figure.
You may find that 512k ADSL would just about work but I think you would be out of the running for 1 meg and above.

I already have 512Kb ADSL for the last year and half now, working fine. I suppose I have to be greatful for 512Kb as I can't never see 1mb or 2mb coming here, Cable didn't lay the cables far enough either, so i'm forced to wait on BT.

So you would say, dont bother attempting to go for 2mb at that 52dB rating?

Thanks John

As I said above you are just within the limits for 512k which is supposed to be 55db max.
My opinion is that being 11db above the 41db limit for 1 or 2 meg (this actually means that the signal received would be just less than 1 tenth of the value at 41 db loss)you would have little chance of the higher speed.

I don't know what the score is if you did apply in whether they have to remove your 512 then do tests.
If it would have no affect on your existing working ADSL then it may be worth trying but I personaly don't think it will work.
