VDSL Stats - Whats yours?

godskitchen · 2013-06-15 15:12:52

Hello all, I thought it would be benificial for us to build a database of VDSL line stats and speeds we are obtaining. I think it could help some people establish if their lines are of poor quality and try and get something done about it. Its also a bit of fun if you are into that kind of thing. For the sake of keeping…

I think you can. I think they put you on the 50Mb package like they did with this guy because you both have similar stats.

Sorry do you mean I should be looking for them to up the profile?

Here are mine.

Think I'd gain much moving to the 70mb profile and should I benefit much from vectoring ?

Yeah, I think they can upgrade you to a higher profile. Best thing to do is ring them and get them to look at your "line attenuation". I said 50Mb profile but I meant higher than 50Mb because you're already getting 50Mb.

Yours is: 13.7 dB
The guy's in my link is: 12.7 dB

You get 50Mb
He gets 70Mb and he could get up to 80Mb with vectoring.

I would just ring them if I were you and them that others with similar stats get higher speeds.

I don't think you can make the 70Mb profile currently, but with vectoring you can make 76Mb.

Rang Vodafone about upping my profile but was told that 50 is all the line can handle.

Oops wrong thread. Sorry mister perfect.

You don't have to be perfect to post a midband speedtest on the right forum, you just need half a brain.

Go on to the forum and discuss it with them: http://community.vodafone.ie/

You might just have to wait until vectoring is enabled to get faster speeds.

I'd say the cabinet you're actually connected to is much further than that. Maybe 700-800 metres.

Nah 90% sure I know the one, it's only just down the road. I don't know how it's looped to it though, may go a scenic route to the cabinet!

Eircom being Eircom often times the cabinet that's closest to you isn't the one you're connected to. Maybe someone on here who understand more about this can assist you.

Seems like everyone is using this speed calculator without reading the notes below the calculator itself.

This tool seems a little better from some check I've done. Hierzo.net
Select DSL Tools -> DSL Caculator - Select VDSL 17Mhz

Does this pump out numbers which reflect reality for others?
Of course, the quality of the cabling to the cab will pull the numbers down

The biggest issue is that wiring doesn't always run the way you might expect.

Remember these networks of copper wires between you and the exchange may date back to a time when there were no data services at all. They were mostly planned to provide analogue voice services (POTS) so things like distance to the exchange wasn't a big deal as long as it was less than about 5km and even beyond that they could get it to work well.

ADSL and VDSL are basically 'hacks' that repurposed legacy infrastructure to do something it was never designed to do. That's why there are issues with signal degradation and attenuation.

Most lines will tend to follow the street back to the cabinet that's between you and the exchange. However, you could find for example if your house was built before others in your area that the phone line takes a different route to neighbouring properties and heads to a cabinet that's further away.

I know one person who has a cabinet on the green outside their house but the line actually snakes around the whole housing estate for almost a km then out the main entrance and back to the cabinet...

They're getting very mediocre speed even though the cabinet is visible from their living room.

"I'd say the cabinet you're actually connected to is much further than that. Maybe 700-800 metres." !!!

His sync rate is, Line Rate: 20.549 Mbps 51.280 Mbps and his actual is 47.19, and 19.18 that means he is more like 200m from cabinet. It would be impossible to get those readings at 700-800m.

Sorry if I missed it, but what speeds and pings (to best server) are people ~150m from the cabinet getting?

You're further than 300m from the cabinet. At 300m, you would get about 60Mb with an attainable net data rate of 90Mb or 100Mb.

godskitchen has similar stats and he reckons he's 700m - 800m from the cabinet: http://www.boards.ie/vbulletin/showpost.php?p=85091467&postcount=1

Not true, his attenuation is certainly that of a line greater than 200-300m. People are getting 50Mbit upto 500m+

Yeap, you should be getting much more. Your stats are similar to this person's: http://www.boards.ie/vbulletin/showpost.php?p=85125082&postcount=3

The person in that link isn't even getting the maximum from his line, but but his "attainable net data rate" would be similar to yours if you had an eircom router.

Just ring them and ask can you be bumped to the 70Mb profile. If that can't be done, ask for the 60Mb profile.

Here is mine:

Line standard VDSL2
Channel type
None
Downstream line rate (kbit/s) 40956
Upstream line rate (kbit/s) 10239
Downstream SNR (dB) 8.7
Upstream SNR (dB) 16.6
Downstream line attenuation (dB) 17
Upstream line attenuation (dB) 6.3
Downstream output power (dBmV) 9.3
Upstream output power (dBmV) 7.8
Downstream CRC 567
Upstream CRC 0
Downstream FEC 3759661
Upstream FEC 960

Before VDSL, I had 10mbit down, .5mbit up. As my speeds seem to never deviate, I assume I'm on a fixed stable profile as opposed to an adaptive one.

You could get much more. Check out this person stats: http://www.boards.ie/vbulletin/showpost.php?p=88140675&postcount=134

He has similar downstream line attenuation as you. He gets 50Mb but he can actually get much more, as you can see from his "attainable net data rate".

Ring them and ask them to bump you up to the 70Mb profile.

Not a whole lot to play with in the downstream SNR though. I don't think it would do 50Mbit but no harm seeing I suppose.

Didn't notice that. Maybe that's why he's on the 40Mb profile. The good news is that vectoring should dramatically improve that when it's enabled.

Yes, 100% that site I refered to in that post is 700-800 meters away, I had an eircom engineer talk me through the route a while ago. He remembers when the copper went in originally.

I take back what I said about Eircom Broadband phone support techs, lad I spoke to was straight to the point and reprofiled my pre-vectoring profile.
