This is because the CIR for BUBA is 45kbps as someone mentioned previously, basically the service they are providing is within the agreed SLA's.

The ISP won't be able to give you a discount, because, again, the service is within the specifications agreed. 
 


So, if my ISP has a SLA with Chorus which involves the 45kbps CIR, then why am I charged the same as my mate in town who gets adsl2 and all the performance he could want?

because it costs the ISP the same to deliver you that 45kbps as it does to deliver the urban person 15Mbps.

My power company doesn't say "you're too far out of town, we'll reduce your voltage to 110V most of the time, but watch out it could hit 230 occasionally. We know you will be happy with lights that glow a dull red...." TCL market the internet to me just the same as to my mate, even handing out 40GB data packs (what sort of a sick joke is that?) yet clearly they are selling a different product.

Living rurally, one becomes accustomed to paying more than townies for many things, but generally we receive an appropriate and acceptable service. Telephone costs more, because almost all calls are toll calls, but availability is fine and the quality is good. Electricity costs more because the line co charges the retailer more, but the network is well maintained. We pay for items in our local body rates which are unavailable to us or which we are unable to benefit from, but it's part of the deal. The list goes on and on...

What rankles is the appalling way that Chorus treats us when it comes to internet service. I for one would be happy to pay extra up front for equipment that would secure us a good and reliable connection, but I would expect to pay the same for the data as anyone else. But under the prevailing arrangement, I don't even get that choice.

Thanks for listening...

Colin

yeah yoiu might pay a little bit more for things like phone calls, electicity etc, but you save an absolute fortune in the cost of real estate that I bet more than outweighs any differences in other things.

A peice of land that might cost $500k in central auckland would probably be $50k in the wops.

Here's a question for the network gurus.

If the backhaul can only handle 4Mbps, then why would you allow the DSLAMS to sync at 7Mbps? The engineer in me feels that in a multi-user environment that this would lead to disaster. (As appears to be the case here.)

Wouldn't you limit the sync speed to say 800 or 1000kbps so as to ensure that no single user can hog the available bandwidth? I suspect that if it was done this way, then the experience for all users would be more consistent and acceptable.

Anyone care to comment? Chorus?

Cheers,

Colin

transmission to the DSLAMs has nothing to do with ADSL sync speed they are both different paths

Well, Auckland is always a special case when it comes to property prices. I won't tell you what you would pay for a decent urban property in this area, complete with cabenitised exchanges. It would make you weep... But it would be cheaper than most rural properties in the current market.

johnr: transmission to the DSLAMs has nothing to do with ADSL sync speed they are both different paths


Please bear with me, I'm just trying to improve my understanding of how-things-work. My admittedly simplistic thinking was like this: The sync speed determines the maximum data rate to the subscriber, right? And if it was  lower, would it not reduce the rate that the subscriber could pull data down the 4Mb pipe? Thus giving his fellow subscribers more of a fair go.

Yes, you're right Colin.  The link with the smallest bandwidth in the transmission chain acts as the bottleneck, and in your case, it appears to be the 4Mbps backhaul link connecting the Conklin to whereever.  If all subscribers had their DSL sync. speeds capped according to restricted profiles set in the DSLAMs, none of them could use more than their sync. speed at any given moment.  In practice, it would be a little less.

So what you're suggesting for argument's sake is that if every subscriber in your area had their sync. speed capped to 1Mbps maximum, it would mean that 4 subscribers could concurrently enjoy say 950kbps maximum speed, thereby meaning that no single subscriber could monopolise more than approx. 25% of the available bandwidth.

To be honest, I'm not sure that it would improve things much.  The current system with sync. speeds > than backhaul speed is pretty much open slather, with contention for the entire available bandwidth.  You might get the whole 4Mbps if nobody is using the net at that moment, or you might get sweet F.A. if everybody else is trying to use the net.

Capping the sync. speed would thus serve only to limit throughput at the top end, but would do nothing to improve it at the bottom end.
