I am just outside the VDSL area for my exchange and I was wondering if Chorus ever allow you to connect to VDSL knowing that the line speeds are not going to be anywhere near expected and I am willing to take this risk e.g. even if I was only to get a minimal increase on my current ADSL line I would be happy with that and wouldn't expect them to provide 50Down/10Up.

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:

This topic is very very well covered probably the most well covered topic on this whole forum.. A quick search of some basic terms will assist you greatly.

 Thanks so much for your reply, the reason I was asking the questions was that I could not find the answer by searching. It appears to be so well covered I cant find it so could you quote a thread where this is covered I would really appreciate it.

If you are outside of VDSL coverage and they connect you to a VDSL port high chance you will be asking to be moved back to ADSL

because the speed will be less than that on ADSL

ring your ISP and ask for a Prequal for VDSL

My old place was 1 house away from VDSL according to the chorus map. They manually provisioned it, and I got 23down/2.5 up. ADSL2 was about 12/1. However you don't know if you will be able to get it unless they have checked. 

 

This might not be the case for you.

its funny that searching is pushed so hard on that particular topic, as if you do search you will find its rather ambiguous.

 

 

 

There are posts from official chorus accounts stating they are looking to extend the reach, there are lines that by the blanket what does a prequal say stance would imply No but have actually go through (@darylblake is an example of this above.)

 

There is a lot of sorting through the outlier cases, to get to the static response otherwise expected. If you take that a step further and look at say, having a long line past the roadside, and the differences between roadside and ETP there can be huge variance there too.

 

Technically, due to the use of US0 on 998, longer lines have more of a chance of being "stable" and likely would net a slightly quicker downstream than previously experienced, Upstream likely wont budge much, majority of the bit-allocation coming from the US0 which the existing adsl service is already using to its extent.

 

Your environment also plays a big part, less crosstalk affecting the signal.. the more likely it will travel longer distances. Crosstalk could be anything, Urban installations likely have more crosstalk due to there being a lot more connections While Rural connections can run past electric fences causing the same effect. 

 

 

 

Realistically, its simple physics. as a line gets longer, the signal attenuates and so you 'loose' a lot of the potential at distance. The differences between ADSL and VDSL connection speeds comes down to configuration factors such as powerlevels.

 

 

 

Remember, the shapemaps are simply estimations.

The biggest unknown is how the copper MPF routes - this is simply an unknown. Just because a neighbor or person across the street can get VDSL2 does not mean that it's a guaranteed - the MPF routing could be completely different possibly hundreds of meters longer.

There also could be some of those dreaded multiples on the line which stuff it up totally for DSL, even tho the attenuation is good.
