Firebreaker:sbiddle: Without some more information from you this thread isn't really going anywhere. Without knowing key things such as where you are the question is totally meaningless.
What speeds does your suburb have now? If it's a rural area is it part of the RBI footprint, remembering that in many parts of the country wireless RBI is the chosen method of delivery for broadband, not copper.
I live in Oratia with speeds of 2.36 average, there is a cabinet less then 2 kilometer down the road but we are connected to an exchange 14 KM away for some reason but I bet this is all futile and will result in no speed boosts.
The only Oratia I can find in NZ is in West Auckland. That area was cabinetised in 2011 and also has a number iof RBI cabinets coming in the next few years to further out other areas of West Auckland and will have wireless RBI coverage for the remaining areas.
Have you actually looked at the RBI coverage maps to see what solution you may be being provided? Since I don't know your address I can't do the work for you.
While your voice services may come from an exchange 14km away your DSL won't come from that as DSL can't work over 14km. Once again without knowing your address I can only speculate that you're either
a) on an existing whisper cabinet and have poor wiring which is delivering your poor speeds
b) on a Conkin from the cabinet which may
a) be upgraded as part of the RBI project
b) be replaced by RBI wireless
Unfortunately at the end of the day there will always be pockets that don't get either. There are plenty of options for communities to build out their own infrastructure, but the biggest issue is getting backhaul into many areas.
