Having read that entire paper I'd suggest the ComCom actually find somebody with some technical knowledge to help them with their understanding of the industry. Not a single mention of ISAM-V cards or voice services delivered from the cabinet which is a pretty key area going forward as more people are moved to this solution.

The ComCom seem to struggle with the concept that "copper services" entails two key parts - the delivery of xDSL over copper and the delivery of POTS services over copper. Spark will shut down their NEAX switches and discontinue POTS services from these long before "copper services" are discontinued.

POTS will just get emulated into SIP outside the customers house

It already is for large numbers of customers.. And has been for many years.

I really wonder how well the mobile network would cope in a major disaster. I am assuming that not all cellsites have battery backup and satellite backhaul.

From my reading of the NGCC concept, it looks like the Govt might put up some money to improve resiliency of which ever mobile network gets picked to provide CC for the emergency services. I wonder if the MBIE could coat tail on this to 'improve' cell site's as part of the emergency calling code?

If Christchurch was anything to go by all the the sites survived pretty well. .

Although the Chch EQ was big and caused a lot of damage, it probably wasn't as large as the 'big one' is expected to be if it hit wellington.

Thats why I have three USB power banks plus a big UPS on my ONT, Router, & ATA Adapter because who knows what will work

See ChCh. Not well initially. Demand killed it.

Actually, I was in one of the worst hit areas of Chch (in terms of broken infrastructure - I was without power or sewerage for several weeks). I never lost Cell or DSL. I think all the providers not only did a spectacular job with their responses, but more importantly, with their planning beforehand.

I was in Ilam, so not badly hit. Couldn't contact anyone for a while afterward.

We live rural with Chorus copper and patchy Spark Mobile network. No Vodafone unless you stand across the road and put your mobile in the air.

We have had two significant medical emergencies in the past two years. In each case we were continuously on the pots line for an hour or so until first responders arrived. If mobile phones were fully charged then maybe no problem. But on average they are about 60% and would not have held up. In the event of a power outage (not unusual) then any battery backup should be able to at least maintain a cell phone, and should keep comms services going for at least 48 hours to allow external resources to get here.

Have responded to the survey, will watch with bated breath.

Having lived in large cities, worked in Telecoms and enjoy retiring away from the masses. We (like others around us) love out PoTS line, at is a critical part of rural life and can be relied on to reach at least other neighbours no matter what.

The carriers (mostly) comply with the Telecommunications Reliability Standards, sometimes used to be called "Carrier Grade". Systems are replicated and built to high seismic and thermal standards. Power generation systems use some of them.

During 9/11 there was a Telco central office beside the twin towers. The two top floors of the CO had external walls stripped off, apart from some data services, all Telco services continued as normal, even though power and aircon was out for days.

You could hoard batteries or generators but the bigger question is, what runtime do the telcos have at your local fibre / xDSL cabinet? Minutes or hours? What backup do they have for cell towers?

As I read the code its that if you have copper based voice (not via ATA) there is no further protection (due to power from exchange or cabinet), it is aimed at those that no longer have copper (FWA, Fibre, HFC), therefore no powered service from outside the house.

I really see this as more of something that st john and other aged assisting providers should be dealing with, not forcing the telcos into providing expensive equipment to their customers.

I don't see the provision of Consumer Premises Equipment by telcos or anyone specifically part of the code. Rather before telcos rip out or otherwise de-provision copper services they need to ensure suitable alternatives have been provided.

In theory CPE is provided by the customer, even if it is sometimes bundled to encourage take up.

Most of the customers I am concerned about will not be aged.
