gzt: How does emergency dialing work on this kind of service?
Bee: +1 How DOES emergency dialling work with VOIP? my understanding is that it doesnt? so if everyone goes fibre and VOIP then we have a big problem if for instance the power goes out at night and you then start a fire by tripping over your gas heater and you dont have a mobile phone... or is there some solution for this?
sbiddle: Emergency calls with VoIP using a "quality" NZ based VoIP operator should be no different to a Telecom PSTN landline. Dial 111 and you're connected to the operator.
In the UFB world all ONT's / RGW's will be installed with a UPS. This is exactly how existing Telecom Wholesale FTTH installations are done and how FTTH installs are done everywhere in the world. Plan for maybe 8 - 12 hours backup before your connection goes down.
Like the PSTN now the weakest link is cordless phone that many people rely on that has no power to operate. It was an issue that many people in Chch discovered after the earthquakes when the PSTN was up and running but because of no power people couldn't make calls.
So I think you are saying with naked dsl + voip there is no inbuilt provision for emergency dialing in the case of power loss - the end user needs to supply a small UPS of some kind to mitigate power loss.
With fibre based Ultra Fast Broadband services you are saying the telco provides a small local UPS good for about 8-12 hours.
My pick for the cases above would be one with a solar charge adaptor I think.
With cordless phones civil defense needs to add 'have a corded phone' to the emergency kit if it is not there already.
