Upload increased?


[link to this post]
 
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

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?

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.
