Re: Understanding interleave and upstream speeds

Example of how people can learn to adapt, alas when I see communications magazines make claims about a data centre with a new 10GB network I do wonder sometimes.

Only 10GB of data allowed, or 10Gbps of capacity....

I expect most people don't know what a lot of acronyms stand for.
In most cases it's irrelevant for them.

Feeling a bit cheesed off. On Tuesday was told that upstream speed would be uncapped within 48 hours. It's still around 440k. Put note on ticket on Friday but no response.yet.

OK, I know this isn't mission critical stuff but surely you guys at PN can do a little better.

I believe amending the content of a ticket puts it back to the end of the queue. An excellent idea crazy.

After reading your original post and all the replies I raised a ticket asking for the (440) cap to be removed from my 21CN ADSL2+ connection. My ticket was replied to within 24hrs to say that was fine and to expect the change within 48hrs. Yesterday morning at approx 7:45am the connection dropped and came back with upstream synced at 888. PlusNet did warn that downstream speed might be impacted, but I've been pushing the connection pretty hard in both directions all today and can't say the download speed is any different. Upstream, however, is a lot better, so really pleased I saw this thread! For those interested, stats now 7424 / 888 (and that's 2 miles from the exchange with a downstream attenuation of 50.5!).

That is remarkable for the downstream - are you tweaking the margin or has the DLM dropped it to 3dB?

Strangely, I would expect the upstream to be somewhat higher, around 1Mbps, on that downstream attenuation. What's the upstream att.?

I think a 'maximum' upstream sync speed of 888kbps often associates with interleaving on. The equivalent of 7616kbps downstream often seen on ADSLmax with interleaving on.

Yes, Interleaving is on. When I first moved to ADSL2+ the line was a little unstable at the new, faster, speed. Turning on Interleaving sorted that out.
