Uncapping upstream - any gotchas?

[#1]

I'm two weeks into life with ADSL2+ and now thinking that a bit more upstream bandwidth would be useful, Before I place the request, are these line stats okay? Router is a Billion 7800N, in case it matters. Current connection uptime is 36h 17m.

Those line stats look fine to go ahead with uncapped upstream.  I've tested your line and reviewed the historic data of the DLM system.  Your loop loss is low (short line and high sync rate), errors are well within limits and the line is stable.
I'd say to go for it.  Worst case, we can return you back to 448kbps upstream if you experience any issues.  If you raise a ticket to request this we'll place the order for you.

Thanks a lot for the prompt reply. I thought the line was good but I appreciate you checking things over, especially on a Sunday morning. I'll place the request later today or tomorrow.

Hi Bremmy,
I've now placed the order to uncap the upstream. It should complete in the next 24 hours.

Thanks again, JoJo.
I'm not sure if you saw my "thank you" response in my ticket as it was Bill Swales who replied to it, so I'll repeat it here.

The connection resync'd at around 3:50am today. The upstream rate now 1167kbps, SNR 6.2. Downstream has been unaffected.

This will do very nicely, thank you!

Hi All,
is the uncapped upload a free service?

[#8]

@petertaylor: Yes (ADSL2+)

@Bremmy,
how did you get those line stats from the Billion, I cannot find all this information on the web interface (though mine's a 7402NX but I believe the web interface is very similar between this and the 7800N)?
Thanks in advance,
Alastair Walker

Log-in via telnet and enter "adsl info --show" (without quotes)
dick:green Quote tag fixed.

Thank you for that info Bremmy, much apreciated.
