Why would you think Attenuation is SNR? It reflects line length.

Just out of curiosity what does G.DMT stand for?
Time for Wikipedia?

Most does mean not all!

Just hope the DLM sorts it out.

Yes, I am aware the PO offer HomePhone on it's own, but with the package I have I very much doubt they would allow me to migrate my phone service away (which I don't want to do) whilst letting me retain their broadband service. The two are linked in such a way that I'm quite sure if you want to migrate the phone side of things away that will effectively kill the broadband side of things.

Yes, all very true, but the point of my reply to you is that you said ' can't have one w/out other' which applies both ways equally. You meant 'can't have BB w/out phone'. So I went on to emphasise that.

Because all this stuff is new to me, I am still trying to learn about it all. I have so many new terms and acronyms floating around my head that it's easy for me to get things mixed up.

It reflects line length.

So what does 53.0dB equate to length wise?

In reply to a post by Bemused_Mike:

Yes, I looked it up. I get the hint. wink

Well that's me told, eh? laugh

Okay, I'll wait and see what happens.

For that info as well as predicting speeds and extensive explanations of terminology & stats it would be worth you bookmarking this site: Kitz - ADSL Broadband Information Site

Okay, fair enough. I'll try to be more precise in future.

In reply to a post by XRaySpeX:
Hence my suggestion to use ADSL2 which won't increase attn.

The signal attenuation doesn't change, it's defined differently in the later standards and ADSL2+ reports "line attenuation" rather than "signal attenuation" - the extra 3 dB is the half of the spectrum that a long line can't use, so it shows a higher line attenuation which doesn't mean the speed is lower than it would be on G.dmt.

MaxDSL - goes as fast as it can and doesn't read the line checker first.

Could I be losing out on about 500kbps though with a 3db increase?
No. There is no 3 dB increase in loss of the signals you are using, the 3 dB represents the extra frequencies provided that you aren't able to use.

At 40-odd dB I was seeing a few hundred kbits/s gain for each step ADSL -> ADSL2 -> ADSL2+
