VDSL Stats - Whats yours?

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 things tidy I propose we could set out the data as follows. I will use a real site I look after as an example and will be adding more when I get time.

Approximate distance to Cabinet = 700 - 800 Meters
Connection to the Modem = 50cm Cat6 (single pair used) from line point of entry into building to NTU.

Using http://www.speedguide.net/dsl_speed_calc.php as a rough guide my line stats suggest I am 1484 Meters away from the cabinet......

I think there is something wrong with the line somewhere.

"Total Attenuation: 18.6 dB 15.8 dB"

That seems way too high to me at that distance.

I will post a site soon with a similar distance to the cabinet so you can compare.....

This is all assuming that the line to your house is not going across town before it gets to you from the cabinet of course.

Site with Vodafone.

Was on 50Mb package. Router reset it self and put the customer on the 30Mb package.

I called Vodafone and told them, they looked at the line stats and said 70Mb would work. They changed the profile and 5 minutes later.....

I forgot to save my speedtest results but it was around 68Mb down and 15Mb up. Fantastic connection.

Distance to the cabinet 150 - 200 Meters

I do actually have the cabinet to myself. I'm the first person on it. I've also chained it up so nobody else can be ruin my beautiful stats & download speeds

I wonder how much speed I'm likely to lose!

I think we are seeing a pattern now......

Eircom are for what ever reason holding back on the up load speed....

Just as a side update, the eircom routers are awful! Iv had problems with all of them at sites I look after

TpLink are coming out with a vdsl router for the Irish market by the end of the year, can't wait.

They are great stats - it'll be worth keeping an eye on. In theory, if they don't contend traffic you should maintain a good service. Maybe the only thing that could affect you in the long term is cross talk from other users coming online on the same subloop.

Finally I was connected today. I ordered Eircom 50Mbit package, I am about 250-300 meters from the VDSL cab.

Actually I am happy with that because since that I really have the 15Mbit upload. It looks like initially they set up the max what the line is capable for, and later they change to the ordered speeds.

Got it installed a few days back with vodafone. Pretty happy with my speeds as the cabinet is about 850-900m away from me.

Distance to my nearest cabinet is ~700m but this seems slow for that distance. Also, when Eircom rang to upgrade us they said the line was prequalified for 40Mbps. Anyone know if this is normal?
