Hi,

Considering switching over from IHUG to Orcons new high speed plans.

Im right on the border of Sunnyvale/Henderson, but looks like im covered by the Glen Eden exchange.

Is there anyway to tell how far away from the exchange I am...so I can get some kind of idea if switching over would be worth it??

Cheers

PhilM

It may seem silly to suggest, but it should help:
Use the new checker facility on the for the vodafone red network. It has an embedded google map which shows the exchange and address, along with a boundary of the exchange coverage

Hi Thanks, I cant seem to get where the exchange is tho.

I can see the coverage (im in it), but that doesnt help me figure out where the exchange is??

Thanks!

no luck - seems like Glen Eden isnt listed there..... you'd think this info would be more easily available eh?

Check

(Edit:opps 0o0 beet me to it!)

http://hwiki.digitalsouth.net.nz/broadband/exchange_locations for locations and links to a map.

This is not a great indication of how far away you are as the cables them selves could take a dogs leg to get to you.

In your modem check what the Line attinuation is. This ranges form 24-64 (correct me if im wrong) 24 giving test results that tell you that you live in the Exchange and 64 being the furthest distence away from the exchange to be able to provide an ADSL signal.

Therefore the higher the attn the further away form the exchange you are.

Hope this helps.

thanks, my modem is telling me this:

Item	Downstream	Upstream	Unit
SNR Margin	12	35	dB
Line Attenuation	41	21	dB
Data Rate	4688	162	kbps

So, 41 down.....that means what...2kms?

41dB / 13.81 = 2.969 KM

Call it 3km and you will be pretty close

Awesome, thanks....so im guessing that isnt too bad....not great, but not bad.

with the 3kms distance, will I see much improvement if I change over to adsl2?

Currently deceiding between Vodafone and Orcon....

Thanks

In theory you should get a speed increase be it 1MB or 10.

Not to sure on how you would calculate the attenuation to speed ratio for adsl 2 as u need to take into account the noise ratio and the state of the coper cables its connecting with.
