As per topic, am I connected correctly or should I save some $$ and go back to ADSL?

 

VDSL went live on 11 Aug (8 days ago as of this posting). I have a master filter that was fitted about 1.5yrs ago by the Coffeebaron, which took my ADSL2+ from just over 10mb to 19mb dwn and 2mb up.

 

My download speed has gone up to 25mb (speedtest.net yields consistent 23mb - an OK increase over ADSL), but my upload is only 1mb (and it struggles to get that on speedtest.net, usually 0.9mb).

 

I went to VDSL2 as all the marketing material states the upload speed can be 5mb up to 15mb. And I really want a faster upload speed for cloud backups.

 

I found a speed comparison on Truenet (granted a few yrs old now), which shows that if I am within a km of the exchange, I should be getting roughly 5mb upload - truenet.nz/story/2012/12/speed-comparison-vdsl-vs-adsl; but as you can see I am not.

 

NB: This sparks another question: Should I even have been offered VDSL?

 

Slingshot tells me to wait for the DLM to do it's thing, but my connection has not changed since day one. OK, i have two more days until the 10 days are up, but I have my doubts.

 

To add it, I emailed Chorus asking "what gives" and they tell me I am on UCLL, and not even connected to their network (as confirmed by checking my address on their site); their email -

 

With regard to your query, I have checked your address details and it looks as though you are not completely connected to the Chorus network. It looks as though you have a UCLL connection, which basically means that the lines leading from your local exchange to your house belongs to Chorus and are being used by your broadband provider. However the equipment in the exchange itself, where the information is processed and sent to you, belongs to your broadband provider/other supplier. Because of this we are unable to comment on the quality of service you are receiving. I would recommend getting back in contact with your broadband provider to investigate this issue further for you.

 

Is this how it is supposed to work for Slingshot VDSL2?

 

Now, I don't want to bash Slingshot, but I find their tech support, well, unsupportive. I feel they do everything they can to make it my issue so they don't have to actually do anything.

 

Any advice would be appreciated.

 

VDSL stats attached.

 

 

Thank you in advance for your time.

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:

you sound like your were on ULL gear if you had 2mbps up

 

you are connected at 25/1 and thats about right for your attenuation so if you already have a master filter their is not much more you can do.

 

for you give you are at the limit of VDSL's reach there is not much more you can expect as at this distance upload suffers greatly

1.5 years ago, highly likely you have a vdsl compliment filter pretty sure @Coffeebaron has been installing them since they out.

 

 

 

That profile looks slightly off, its even more interesting considering your quote from chorus.

 

Your line length itself, on a urban connection is preforming exactly as i would expect, Boost in downstream, Move over to PTM. PTM itself will offer less overhead, so even with the same upload speed it will be slightly faster.

 

 

 

with the release of 998, Chorus did extend the reach of vdsl. however with 998 being more asymmetrical longer lines struggle a little more to get a decent jump in upstream.

UCLL is unbundled copper local loop. This means your phone wiring is connected into a DSLAM probably owned by Slinghot instead of Chorus. So yeah, Slingshot has visability of whatever DLM setup is configured.





Qualified in business, certified in fibre, stuck in copper, have to keep going  ^_^

As far as im aware, slingshot (or vocus for that matter) arent publicly doing service for VDSL over UCLL though?

 

 

 

I do recall it was possibly in the works but i would question risk of crosstalk if profiles differ to chorus.

 

Possibly @noroad would have an idea if VDSL on UCLL has gone properly live on 'vocus' DSLAMs.

Correct, if you moved to VDSL, you will no longer be on slingshot equipment. 

 

 

 

You will be connected to your local cabinet/exchange to Chorus equipment.

Appreciate all the feedback.

 

I'll have words with Slingshot as I feel they should not have offered me VDSL without making it clear I should have got a pre-qual first to determine my speeds, especially as they advertise:

 

"Expect download[s] between 15 and 50 Mbps and uploads between 5 and 10 Mbps."

 

...and I am barely getting 1mb up - was twice better off on ADSL2+ w/ Annex M enabled. Plus I am paying more for a not much better connection. I'd rather have the money.

 

 

 

Off to contact Slingshot -  wish me luck!

 

 

 

Cheers.

Generally VDSL will do 20+ and 5+ however, you need to understand you are a border case.

 

 

 

In your particular situation you have a choice, Download speed or upload speed.

 

Prequals are not exact, they could estimate over, they often estimate under. There is no telling for instance how much crosstalk there is on your line or the quality of your copper pair. (Slightly out of context but: annex m actually does cause crosstalk with annex A among others, One could easily argue, that it should not be offered because of the affect it can have on other customers)

 

 

 

on VDSL you will get better download speed (plus PTM which has less overhead). You will be under the control of what DLM does to your connection

 

On ADSL, in your case you can go UCLL and get back to your normal download speed but get up to about 2mbit up, Likely with control over interleaving.

 

 

 

To put it into another context, you are comparing apples with oranges.

 

Ask slingshot to switch you onto Chrous ADSL. 

 

A quick highly likely prediction would say: you will likely get about 15/1 if your lucky. You will notice the difference the more aggressive profile of UCLL makes. You will certainly be happy with the move upto VDSL in that case. 

 

 

 

As it stands,

 

Chorus ADSL will get you up to 24/1

 

UCLL ADSL will get you upto about 24/3 (i dont have exact numbers of what the dslam fixes as max sync in their profile on hand) - Also remember annex M reduces your effective downstream due to the part of the spectrum used for the extra upload.

 

Chorus VDSL will get you upto 100/50.

 

 

 

In your case, you are pushing the edge of physics, where VDSL's reach simply doesn't reasonably reach. Sure, it could be ran on a lower snr or higher power level much like you may see with UCLL but chorus have to draw a line of "balance" with their profiles.

@pSych0bUNny are you in a VDSL Area? if so those boundaries are just estimates and are based off distance and the assumption that your line is of reasonable condition. Some people like yourself end up in this situation because your line is probably pretty poor, which is very hard to identify untill you actually get a service sonnected.

@Jase2985 I appear to be just outside the VDSL zone according to the map at ufb.org.nz, but in zone according to Chorus.

I got in touch with @coffeebaron regarding my filter compatibility and his reply:

[i]I have looked at your address though and you are actually outside of VDSL coverage, by quite a bit. Also if you were on Slingshot LLU gear before, then you would have been getting higher than normal sync speeds due to lower SNR, so the jump to VDSL would be not much better else worse.

Best would be back to ADSL if that was better.[/i]

Again as VDSL is costing me more, I'm going try to go back to ADSL. Only two more years until fibre.

Cheers.
