<p><font size="2">Thank you all for taking the time to reply, I really appreciate your quick and informative responses.<br>
<br>
So my understanding now is that Maximum Line Rate/Attainable Rate ≠ Line Sync Rate.<br>
And to avoid a hypothetical scenario where I get stuck on a contract paying for a 50Mbps service, that will only ever allow me to see 30Mbps - I need to connect a modem that shows the maximum attainable rate, to see what I can actually achieve.<br>
<br>
Unfortunately it doesn't appear my new learning project provides that information (unless a VDSL connection shows detail than a ADSL connection does) - so I'll have to borrow something to examine that further.<br>
<br>
But I'm very much looking forward to being able to push through more than 13/0.8 !<br>

<br>
You should be able to see the maximum line rate (depending on your modem) -<br>
I've got an ISP Supplied (Internode) Technicolour TG-789.<br>
<br>
We're about 20m from the pillar and have a 100/40 service - max line rate<br>
appears currently at 140/57 (see below)<br>
<br>
DSL Stats:<br>
<br>
Maximum Line rate: 57.62 Mbps 140.91 Mbps<br>
Line Rate: 44.19 Mbps 107.73 Mbps<br>
Output Power -1.1 dBm 8.3 dBm<br>
Noise Margin 15.4 dB 15.6 dB<br>
Line Attenuation 3.1, 12.3, 18.5 dB 7.7, 16.3, 23.5 dB<br>
