Telecom are currently trenching fibre right past our house in Opawa/Woolston in Christchurch.

The local fibre cabinet is going to be 40 metres away (as opposed to the 2-3km distance we have now to the existing exchange).

That makes me think there's potential for a massive broadband speed increase using ADSL-2 when the work is completed at the end of the month.

Has anyone on list had a similar fibre upgrade in their area with the local fibre cabinet close by?

Did it give you a significant increase in broadband speeds over ADSL-2?

Thanks!

Assuming this is one of the standard whisper cabinets they are rolling out nationwide, the fibre is used between the cabinet and the exchange for backhaul.

If you are that close you should get a great sync speed in your adsl modem/router assuming your house wiring is good quality and has minimal problems once it's all up and working.

The whole purpose of the cabinet program is to deliver >10Mbit sync speed to 80% of the country. I would say you should expect 15Mbit-20Mbit sync speed being that close.

Bad internal house wiring can cause a lot of problems and interference though, so be warned you might have to do some work in that area.

Also sync speed doesn't always translate into better real world download speed though, especially internationally.

They installed a whisper cabinet around 30 meters down the road from me (last month).

It took a couple of months work to change over after the physical cabinet was installed.

After the cutover, my connection speed doubled.

I can download from the web , at 1.6 MB/s, on my broadband adventure plan.

So, a 1000MB file, would take around 10 minutes to download.

I can blow my entire 20gb cap , in just over 3 hours.

The caps look pretty crappy at such high speeds.

Well this is promising then. I'm currently getting 0.56 MB/s so potentially tripling that speed would be great.

What is your upload speed now?

I work from a home office doing internet consulting so the upload speed is my biggest frustration. If I record some training videos for a client it takes forever to upload at 0.1 MB / s I get at the moment.

What are you ADSL router stats at present? sync rate and signal streangth?

0.56 is a terrible figure and would tend to indicate an issue with the line such as wiring issues within your house. Do you have a master splitter installed or just plugin filters? If so how many do you have?

Not that I was stating speeds in MB/s not Mb/s just in case that was causing confusion.

I've always assumed that the upload speed would be much lower than the download speed. If that's not the case let me know and I'll start chasing up with Telecm.

Here are the stats from the D-Link DSL-504T modem:

Modulation ADSL_2plus
Annex Mode Annex A
Max Tx Power -38 dBm/Hz

SNR Margin - Downstream 12dB / Upstream 12dB
Line Attenuation - Downstream 39dB / Upstream 25dB
Data Rate - Downstream 5325 / Upstream 781 kbps

We have a master splitter and filters on the two sockets in use. I believe there are 3 other socks in the house not being used.

Thank you!

DSL 504T modems have problmes with adsl2 - I think they are capped at about 7.5mb. You'll need to change your router/modem if you want to take full advantage.
