OldGeek: Do those who install a UFB connection continue to use any PSTN services?  I would have thought that UFB plus VOIP would be all that is needed.


I suppose the key question is whether the PSTN is still the central interconnect - if two UFB customers call each other, do the calls still go via the PSTN?


This may be ISP-dependent; it wouldn't surprise me if some of the smaller providers are only using VoIP "last mile" and are still feeding everything back to the PSTN.



I was told that sparks core network is involved in most phonecalls, even those between other telcos for legacy telephone network reasons. That might change with their move to a current century technology however.

The PSTN still forms the basis of SS7 voice interconnects between big providers in NZ, regardless of whether end users are on VoIP or copper services.


While IP interconnects are in place and used by some providers for traffic there is still a long way to go before everything is IP. This change will be as fundamental as removing customers of the NEAX's, and it wouldn't surprise me if we'll still have some NEAX's just handing interconnects for a long time after they stop providing POTS services to end users.

Chorus own most of the exchange buildings, not Spark. Spark simply own the NEAX switch that sits inside it.


UFB and copper equipment will still exist inside the cabinets as it's only the NEAX that's being shut down. There are still no definitive plans to shut down any part of the copper network, xDSL network or to stop providing voice services over copper using the ISAM-V or UCLL solutions.




Just had a thought - Who owns the PCM circuits, equipment, endpoints ect? Which presumably are connected to the NEAX switches. (Can the PCM network operate without the NEAX switches)?


As the only thing worse than living in an area where your only internet access available is via a conklin, Would be having the landline permanently disconnected. No cellular, and your only internet connection too congested for VOIP to work over it.
