OK, so the title of '"Abnormalities" in Chorus network...' is a bit vague, so let me see if I can explain what's going on. I live in rural NZ, in Golden Bay, at the northwest tip of the South Island. Lots of people in the area have been gagging to get broadband for years (and I do mean years... a lot of people struggle on with dial-up at the moment, which must be *so* frustrating!!). Over the last year, Chorus have been laying fibre optic cable between Takaka and Collingwood, and upgrading some of the roadside cabinets (i.e. TAK/V, TAK/B, TAK/AK, etc. -- see http://goo.gl/maps/D3BNk). I believe the fibre optic cable is now all in place and operational, as the Vodafone transmitter on Mt Burnett, near Collingwood has just been upgraded and is chucking out 3G (4G?) signal, whereas it was just 2G previously.
I've been speaking with a number of people in the area. Some live on Patons Rock Road, some live on "Puramahoi Straight" (that is, on SH60, between the Patons Rock Road turn off and Takaka Airport), and some live in Rangihaeata, on Rangihaeata, Keoghan and Fraser Roads. They have told me stories about how, in the past (i.e. years ago), they have been told that the quality of the old copper network was so poor that Telecom (as it was back then) couldn't even provide dial-up over the phone lines. One person was told that there was a "coil" on their line which prevented this. People on Patons Rock Road were told they couldn't be connected to the phone network, as there weren't enough connections available, and so on.
As we will soon be able to reap the benefits of the RBI rollout, people are asking me now whether they will be able to get broadband.
Looking at the Chorus Broadband maps, there seem to be some interesting "holes" in availability of ADSL2+ services. Specifically, if you look up "Onahau Road, Puramahoi 7182", but then go back to SH60, you'll see that there is "good" ADSL availability towards Patons Rock Road, but then it abruptly stops. Similarly, if you search for "Keoghan Road, Rangihaeata 7182", there is "good" ADSL availability for the first third of the road, but then it appears to just stop.
If people live in these "holes" of coverage, are they sod out of luck? Are there any technical reasons--"coils" on the line, poor quality copper cables, etc.--that really do prevent ADSL being delivered to these places, or is this just apochraphyl? For some of these people, they have seen Chorus dig ditches in front of their houses, lay spanking new green pipework for the fibre optic cable, so they know it is right in front of them, and if they then cannot get broadband, sheesh, they'll be unhappy.
I was wondering whether any Geekzoner is able to check out some specifics for us...?
(Also, as an aside, I see that Chorus are now "advertising" (http://www.chorus.co.nz/rural-broadband-initiative/fibre-in-rural-community/fibre-to-rural-communities-1) that people may be able to connect to the RBI fibre -- does anyone know much about that? The applicable maps on the Chorus website show extremely few places where new ducting was laid in Takaka, despite new trenches being dug all the way between Takaka and Collingwood, and, for example, new "manholes"--that is, big cylindrical concrete pits--installed in the ground along the way, as at the end of Onekaka Iron Works Road...)
Thanks for your time, guys. Here's to hoping someone can shed some light on this.
