Specifically, he assumes that NZ 's VoIP telephone will be delivered over IP all the way to the subscriber's home. I doubt that is the plan. More likely, they are planning to replace all of their end-office and tandem switching infrastructure with a VoIP/softswitch architecture. This will almost certainly include line gateways in the central office which will provide dial-tone and battery over the existing copper wires to the home and look to the customer no different than today's services. These gateways provide the same 'line power' and battery backup capabilities of the existing circuit switches. So why make the change? NZ can probably achieve efficiencies by moving to a converged IP-based core network, plus they can more easily add and integrate IP-based features with this architecture and ensure a smooth transition to voice over broadband for those homes and businesses with broadband who want that capability.

If the entire system is going to be converted (though the number of lines involved is relatively small in the scheme of things), it has to be 100% coverage one way or another. Then there are all the related issues of phone backup power supplies, getting recharge power to those supplies, maintaining the batteries, and lots more. All *sorts* of interesting issues come into play when you convert everyone's lines to VoIP, since they have to be emergency capable. I wonder if those quoted dates turn out to be about as real as our analog TV cut off dates here in the U.S. have been? --Lauren-- Lauren Weinstein lauren () pfir org or lauren () vortex com or lauren () eepi org Tel: +1 (818) 225-2800 http://www.pfir.org/lauren Co-Founder, PFIR - People For Internet Responsibility - http://www.pfir.org Co-Founder, EEPI - Electronic Entertainment Policy Initiative - http://www.eepi.org Moderator, PRIVACY Forum - http://www.vortex.com Member, ACM Committee on Computers and Public Policy Lauren's Blog: http://lauren.vortex.com DayThink: http://daythink.vortex.com ------------------------------------- You are subscribed as david.e.young () verizon com To manage your subscription, go to http://v2.listbox.com/member/?listname=ipArchives at: http://www.interesting-people.org/archives/interesting- people/
