Sky LLU due tomorrow

Well after 5 long weeks my line is due to be activated tomorrow.

will update on how it goes, will post some stats of my 4mbit sync that they set you on.

The 4 meg sync is not guaranteed!

well im waiting lol, 1 hr 30 sleep!

Up early with kids, got a 3 weeks old and a 5 year old....5 yeard old was up first!!!

ADSL Link Downstream Upstream
Connection Speed 4095 kbps 605 kbps
Line Attenuation 32.5 db 20.1 db
Noise Margin 15.2 db 17.3 db

however i know my attenuation is 4db lower on the upsteam. My GT always reports is higher then every other router so its almost the same as my TT line

DLM has done its first change...bit disappointed was expecting 14mbit and a higher upload with the spare snrm there!

Need to get another router, not sure if the funny snrm it reports on the upstream has caused that.

Speedtest with dual wan so not just the sky speed

Your pretty much perfect for your line. If anything above average for that attentuation, in my experience. Although some websites would argue differently.

Also be warned that buying a new router will make no odds, it's against T&C and is lots of money wasted IMO.

Sky set the sync speed via DLM so once it's over, you'd connect at the same sync everytime. E.g. if DLM had ended now you would resync at a max of 13476kbps. It's like a physical cap on the line. So every router would yield the same sync. No router could get above 13476 kbps. Some may sync less granted.

The upload may change, although you're unlikely to see above 1000 kbps as Sky generally don't go above this for some weird reason.

I think it's looking pretty much perfect.

I certainly don't expect your line to get any better speeds, if anything I'd expect .5 - 2 meg less once DLM finds a perfectly stable sync that will never drop out.

will ring up once training is done and ask for the gaming profile, then i can tweak my snrm.

My tt line sits at 16800kbps with 3db snrm, no problems or slowdown or to many errors to cause a issue.

Quite happy considering i wont get any form of fibre unless the Council is sucessful in its BDUK bid. I have seen the viability of our county and i think only 3 or 4 exchanges are going to get fibre up to 2016/17

will ring up once training is done and ask for the gaming profile, then i can tweak my snrm.

AIUI once the DLM has finished the line speed will be capped. Therefore any amount of "tweaking" won't change that. The gaming profile reduces the level of interleaving but doesn't increase the speed of the line.

If sky provided fastpath (gaming profile isn't fastpath) with a normal snr of 6db he would see at least another 2mbits sync with an attenuation of 32db which probably is actually less, my router reported my attenuation as 32db the lines actual atten was only 28db, my sync at 6db was over15mbit fastpath (ukonline)

the chipset in the router can and does make a difference in sync speed, if the op is connected to one of the old easynet dslams they will show up on a tracert as cr0.xxx.uk.easynet.net at the 1st hop after the router then using a router with a conexant chipset would give better sync, but with the netgear dg834 v5 manually over riding the target downstream snr isn't supported , so a router such as the billion 7204 nx or rx would be required,
as for use of your own router, why not (sky t&c's) well i have never heard of anyone getting thrown off because of using their own router

as for the line being capped by dlm if this is the case this can be changed by sky, but as adsl is rate adaptive then the theory of dlm on llu hard capping a connection is shot down, whilst dlm will serve to cap a connection by increasing the target margin, once it is no longer active then it should sync at the fastest speed possible, and lowering the snr would enable a faster sync, but if as a result this caused errors /packet loss ,this could cause dlm to run again if it's threshold was met

ive read on multiple forums once you are on the gaming profile you can tweak the snrm, i will wait and find out myself.

Sky staff recently confirmed they do not currently penalise customers using their own router: http://helpforum.sky.com/t5/Broadband-Technical-Issu...

I would be very surprised if they ever do, to be honest.

Can you point me towards one of the forums, I was considering asking for the gaming profile, but understood the snrm couldn't be tweaked. I would like to read up to date info on it.

When you request the gaming profile, the line is uncapped and the interleaving is reduced.

so far on day 3 of training

ADSL Link Downstream Upstream
Connection Speed 13765 kbps 1098 kbps
Line Attenuation 32.0 db 20.0 db
Noise Margin 7.7 db 8.1 db

<Green> with envy

my combined speed i would think its probably the quickest in the whole of north shropshire for a residential speed.

very happy with it, they can keep fibre

still <green> with envy

just to show the difference between my sky line and tt line

Sky line

ADSL Link Downstream Upstream
Connection Speed 13765 kbps 1098 kbps
Line Attenuation 32.0 db 20.0 db
Noise Margin 7.2 db 8.1 db

24db@300kHz - estimated loop length 1660m

TT Line (d/s snrm is set to 3db)

ADSL Link Downstream Upstream
Connection Speed 16859 kbps 1020 kbps
Line Attenuation 33.0 db 14.1 db
Noise Margin 3.0 db 12.9 db

26db@300kHz - estimated loop length 1552m

You can't go as low as 3db noise margin on Sky, the lowest they go is 7 db so you will lose a good 2 meg there. Shame really.

Hope you're happy anyway...

Mine has recently been connected too, 6 days since I migrated to Sky, I've used a 2wire 2700hgv from the outset. Current stats.

Protocol: G.DMT2+ Annex A
Downstream Rate: 17020 kbps
Upstream Rate: 1069 kbps
Channel: Interleaved
Current Noise Margin: 7.2 dB (Downstream) 9.1 dB (Upstream)
Current Attenuation: 18.2 dB (Downstream) 9.8 dB (Upstream)
Current Output Power: 16.7 dBm (Downstream) 11.7 dBm (Upstream)

Unfortunately the upstream seems to have gone down as it was slightly over 1100 for a couple of days.

Coming from Plusnet Pro which was:

Protocol: G.DMT Annex A
Downstream Rate: 8128 kbps
Upstream Rate: 448 kbps
Channel: Fast
Current Noise Margin: 12.0 dB (Downstream) 25.0 dB (Upstream)
Current Attenuation: 15.6 dB (Downstream) 8.0 dB (Upstream)
Current Output Power: 19.8 dBm (Downstream) 12.2 dBm (Upstream)

Quite please so far, seems fast at all times of the day and is half the price of PN Pro. Given my attenuation I was expecting 20 Mbit but looks like I'm held back by noise. Not bad really since the exchange is 558 metres line of sight or 805 metres by road so based on distance Kitz suggests 7.5 Mbps and Sky suggested 8 - 10 Mbps. PN Pro gave me priority over other customers which was good (not that I notice this now as the Sky is way faster) but also traffic shaped to the extent of giving priority to streaming and browsing; I think this is why I am seeing now that if I hammer the line downloading I can't use HTTP (no traffic shaping and no QoS on the router). Guess i'll just simply throttle downloads a bit but will investigate QoS on the 2wire if it can do it or traffic shaping via my Ubuntu server.

just noticed my attenuation for the upstream seems to have righted inself from 20db to

ADSL Link Downstream Upstream
Connection Speed 13309 kbps 1101 kbps
Line Attenuation 32.0 db 15.8 db
Noise Margin 6.4 db 7.5 db

its really 13.8db, this netgear always reports it 2db higher

d/s seems to have dropped from 13700 but upstream is doing well.

so both my lines are practically identical attenuation wise however i notice the sky one suffers from noise worse then TT

So if you were to compare the actual use on the SKY and TT lines, how would they compare.

* Raw download
* Games
* Web Browsing
* Work VPN
* {others}

cant really tell as they are bonded so dont see any difference at browser bar faster speed.

however im having to route my ps3 traffic through my TT line as the ping currently while in testing with sky is quite high, im hoping it will settle down.

The TT line is much more stable then the sky line but will see what i can do.

The TT line has pro rj11 cable and a bt nte2000 faceplate while the sky line has a normal rj11 lead and a adslnation faceplate. So far, the BT faceplate seems to be better on my TT line as i had the adslnation on it before.

I might invest in another bt nte2000 soon for the sky line, waiting for the 10 days to be over so i can ask for gaming profile.

I can't believe that people are complain that they can't get more than 13megabits. Maybe you would like to cope with 4megabits or how about 1?

I am not envious as the speed I got does what I want, just fed up of people complaining that they can't get the speed they thought they would get

its not a complaint, i never said that, just the difference in my two lines.

Fair enough, but people do moan about getting 14megabits then they thought they would get 16.

Now if I lost a couple of megabits it would be a lot to lose, but when you get to 8megabits or more then be happy with what you got.


I am happy with my 4megabits BTW, more than I ever got before here.

all done, line is complete with training.

My total now in balanced mode

happy in a town with 3k lines

Can you describe in full how you bonded the lines?

Did you use a third party subscription service for this?

Thanks.

You're joking right? Probably less than what you pay

well total cost

TT LLU - line rental + retention deal + all calls bar prem numbers = £13.95 a month
SKY LLU inc line rental = £19.50

Total £33.45, am im happy to pay for it Worth it for me .I am now smoke free for 4 days and counting, the money i save in 4 days not smoking will pay for it easily each month, this was part of ''my deal'' with myself.

does that now mean you have 100% packet loss !!!

lol

that it does!
