To help put your mind at rest, uncapping the u/s was no issue for me. I just sent in the request via the portal, it was acknowledged within 12hrs and happened the next day.

ADSL Link Downstream Upstream
Connection Speed 6870 kbps 888 kbps
Line Attenuation 50.5 db 24.7 db
Noise Margin 4.2 db 9.1 db

That's still capped though. Should be 1Mbps+ on that attenuation.

In reply to a post by RobertoS:

Uncapped PN adsl1 upstream for me was previously 832K - so 888K is a bit faster

As Roberto said - it should be above that. Mine sync's at about 1055Mbps ish!

Can't see where the hassle is that you've heard of in uncapping the upload. I didn't even start a ticket - it was all done from here by a CS rep

888kbps is the maximum uncapped value when the upstream is interleaved

I disagree there Jim. Mine is interleaved and sync'd at 1055ish.

Speedtests give me over 1Mbps uploads consistently as you can see from my sig.

I said upstream interleaved that is separate from downstream interleaved

My Router says the connection is interleaved. Does that only apply to the download then?

Usually it does.
On my Netgear I can only find out the upstream interleave depth via a telnet command

Thanks to all who contributed, very interesting. My connection is certainly on interleave because it was very unstable with the original fastpath setting. Interleave sorted that out straight away. I'll have 888 and stable over 1.0Mb unstable every time!

Cheers
