Hi,

I've been toying with the idea of going VDSL for some time now and dropping the normal line and go VOIP enabled.  I'm within the VDSL range, as the cabinet 'isn't' that far away (I realise physical distance doesn't represent actual).

These are my stats from my current dsl router:
 
                              Downstream Upstream
Data Rate                     14329        1240
Noise Margin                    12            12
Output Power(dBm)         125          189
Attenuation(dB)               18             5

Thanks,

Chris

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?

Based on those stats you're outside the VDSL2 coverage zone. Without knowing the state of your wiring however it's impossible to know whether you're actually capable.

Does the Chorus coverage map put you in a VDSL2 coverage area? If so there is a very good chance you can get VDSL2 but you will need to sort out your wiring.

Hi Biddle,

Yes I can get VDSL2 as my cabinet is enabled and I'm within the available zone according to the chorus map.  I've got brand new wiring from the demarc point including a new master splitter to two new jack points, one is for telephone and the other ADSL.

I did used to get sync speeds of around 19000kbps but they suddenly dropped about 9 months ago to the levels that posted.

it seems a lot of people are being hit with increased attenuation and reduced sync speeds even when in green coverage area.  i suspect that part of it could be increased uptake of adsl in general with longer lines interfering with the shorter ones.

like your line stats look similar to mine, and i'm around 600 metres from cabinet in green vdsl area.  but measured sync speed was still 14 megabit at the road.

unfortunately it seems all new work is going into ufb, so if you're not in a ufb area, and you're over 10 megabit down, then it's unlikely anything will be done.

that said if chorus let you have vdsl, you'd at least get better upload speed.

at the moment you're basically hitting maximum adsl non-annex-m speed.

Hi Mercutio,

I thought as much, hey I'm still not complaining at what I have but it would have been nicer to have a faster line.

UFB in my area is not on the 3 year plan yet :-( so some time still to go!

While there may be a crosstalk type effect on the other pairs I don't believe it is aas big an issue as some may think. I think most of the time people just see that there is a cabinet close to but don't actually know which way the cable goes down the street. I was at a customer's house not long a go with complaints of slow speeds 'even though the cabinet is just there'. The cabinet was only 500m away but after getting the plans and measuring there was actually 2.3km of cable between them and the cabinet. This was because the cabinet got swapped to the other side of the road during the FTTN upgrade. I suspect this is the case with many of the FTTN cabinets.

And then there is the old house wiring gem.

To the OP - Get your house wiring checked out and then re-visit your modem stats. You might see a great jump in performance. I haven't seen many connections within the 'VDSL' area not benefit from a splitter install. And as for going VoIP, do it anyway on your ADSL. Call quality and stability will be fine!

Edit: Just to add. I have 29dB attenuation on my line and sync at around 11Mbps just to give some context to your figures.

Edit one more time: Sorry to saw another post. Get in touch with your ISP and get them to send Chorus out. Sounds like the line has degraded and if you have a splitter and new wiring I would suggest it is the incoming pair.
