Our local exchange has just been upgraded from ADSL1 to ADSL2 / VDSL
We are about 2.6 to 2.65 km of copper wire away
DSL line speeds are currently 5371 / 861 Kbps

I like the idea of VDSL with possibly higher upload speeds but looking for some feedback please?

Planning on moving from Orcon to 2Talk now we can with upgraded exchange (we have a few VOIP connections that are pretty busy during the day and had to go to RBI about a year ago as ADSL1 got too congested but with ADSL2 now don't have any issues any more)

Keeping RBI as a backup connection still.

Is it worth going to VDSL?
Any ideas of speeds we might get?
I cannot find anything that gives VDSL speed vs distance anywhere?

Telecom site says it can offer VDSL or ADSL2
2Talk site not working for checking. (If i put in wrong address it says it does not exist. If i put in correct address it just does nothing :))

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

 



 

If you are posting regarding DSL speeds please check that

 



 

- you have reset your modem and router

 


 

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

 

- you are not being throttled by your ISP due to going over the monthly cap

 


 

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

 


 

- you read this topic and follow the instructions there.

 



 

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

 



 

- Your ISP and plan

 


 

- Type of connection (ADSL, ADSL2, VDSL)

 


 

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

 


 

- Your general location (or street)

 


 

- If you are rural or urban

 


 

- If you know your connection is to an exchange, cabinet or conklin

 


 

- If your connection is to a ULL or wholesale service

 


 

- If you have done an isolation test as per the link above

 



 

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

 



 

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

 



 

I recommend you read these two blog posts:

 



 

- Is your premises phone wiring impacting your broadband performance? (very technical)

 


 

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

The chances of getting VDSL at 2.6km are essentially zero - the cut off is about 1km, depending on attenuation.

What are your current ADSL line stats?

Thanks.
That is what I thought with distance but could not find anything that gave distance vs speed.

In general terms, Chorus won't install with attenuation above 10.8dB - it's measured slightly differently to ADSL, but if you look at your downstream attenuation, I think you'll find it is far higher than this, given your sync rate.

Post your line stats up here anyway, as that sync rate looks a bit low for the distance anyway. It may be that you need to address some wiring issue at the premises and you can get a better rate from your existing connection.

43 dB down is indicative of 3.1 km or so.

Yep, 43dB is far too high to even consider VDSL.

Read some of the info in PeterReader's post above, and look at doing an isolation test - essentially you need to try connecting your modem to the line where it enters the house, with the rest of the house disconnected, and see if you can get a better connection -if so, a properly installed master filter will see you getting the best possible out of the connection you have.

Even if u get vdsl you could end up slower than adsl2 ...

Sorry to slightly highjack the thread, but how different is the measurement for VDSL from ADSL for line attenuation? 


I'm slightly concerned now because mine is 5dB up and 12dB down and I've just signed up for Snap VDSL.

EDIT: just to correct that...

Really? But doesn't it fall outside of chorus' specs for VDSL?

No master filter as far as I'm aware. This is a rental property though, so not sure, there could be.

well my ADSL sync was alot lower then yours and higher attenuation and i've got VDSL just fine :) you should expect to see around 30-35/10 in speed

I dont know the exact difference but my line jumped from 2db to 10db downstream when switching to VDSl. No difference had a line filter etc with ADSL. Its a different technology its hard to compare such.
