Upload increased?

Has anyone else seen an increase in the upload speed on Sky's ADSL2+ LLU?

It looks like it has been uncapped from 1Mbps (think It synced at 1112kbps) to allows full up-to ~1.3Mbps.

Looking at my Sam Knows white box graphs this change happened yesterday. Also pings have decreased from ~24ms average to 19ms average. So it looks like Sky have been tweaking their config. This now means Sky have managed to match the speeds I did have with O2 but with O2 I had lowered the SNR to 3db where as Sky is still at 6~7db.

Every little helps.

DownStream Connection Speed 18011
UpStream Connection Speed 1212

I suspect I could hit 1,300 kbps if I was uncapped, with probably 18,500 kbps downstream. Anything like that would be per-exchange, so perhaps a change is being rolled out.

The legacy easynet kit was capped at 1216kbps for some reason or other, and even Dan wouldn't or couldn't increase further, but the kit should be able to handle 1.3mbps

Found when the change first happened in the logs:-

Not sure the exact date the FTTC cabinet whet live, could it be people moving to FTTC and therefore not causing crosstalk interference for ADSL2+ so line speed has improved?

What are your downstream and upstream noise margins now?

Broadband Link Downstream Upstream
Connection Speed 16353 kbps 1252 kbps
Line Attenuation 29.0 dB 17.9 dB
Noise Margin 6.0 dB 7.7 dB

In reply to a post by 5km:

Noise Margin 6.0 dB 7.7 dB

Still some spare there until it gets to 6 dB, but it's an improvement.

Mine's always been way too high at around 10 dB:

Broadband Link Downstream Upstream
Connection Speed 18011 kbps 1212 kbps
Line Attenuation 29.0 dB 16.1 dB
Noise Margin 6.1 dB 9.9 dB

Just noticed we have the same d/s attenuation. The Openreach engineer I had around recently was impressed with the synch for my line length.

For the length of my line the attenuation is not impressive and sync falls below what is theoretically possible for 29dB, I'm only 320 meters from the exchange at the crow flies.

Same here, rebooted and still on 1137 wwith 10dB of margin. Would dearly love a bit more up....

Whitstable exchange. ...

Hmm mine are a bit weird now

Connection Speed 17020 kbps 1212 kbps
Line Attenuation 25.5 dB 15.5 dB
Noise Margin 2.8 dB 9.9 dB

i used to get over 18500kbps ...meh.

But 2Km as the telephone line is laid

And yet by road it's only 800 meters and that is going the long way. It is possible to walk to the exchange in 480 meters, but that doesn't follow the most likely route for the line.

£25 per month for a phone line. Wow they have hiked the prices or did you mean £15 per month?

I read it as £25 all in: line rental and BB

My bad. Clearly I was up too late and couldn't read. lol.

That's where you're going wrong. You have to take in to account the convertion from meters to metres.

No worries I'm the same especially at that time of night

Even converting from US to British the length is the same so this does not account for the difference in length.

G.INP. Physical retransmit. Less overhead on interleave, faster speeds!

Pedantic - who looks like the fool now?

What? Being able to spell when trying to put someone down is a must!
