Hi there,
I'd like to test a medical device in Auckland, New Zealand. The device uses analog phone lines to connect to the internet. My problem is that I do not have too many contacts in New Zealand to test the device. If you live in NZ, could you suggest places I can try to test it? The requirement is the phone line needs to be analog, or analog/broadband.

Your help is very much appreciated. The device will save lifes for many New Zealanders.
Thank you...

Do a search for a telepermit company here, they should be able to test it for you, plus get it telepermitted for use on Telecom's network.

Well, I do not want to give them the device yet - I want to test is and adjust modem characteristics that the device has. The device is no in production yet, that's why I wanted to visit NZ and find some locations I can test it in. Suggestions?

You are the designer but analogue modem performance should be a known quantity by now and analogue lines are on the verge of being replaced by IP based solutions.

Not from what i heard from a reliable Telecom source yesterday that the existing NEAX exchanges are going to be kept going until at least 2020 and the older "K"  type exchanges upgraded to "E" type. The NGN is on the back burner.  Who knows where they are getting the upgrade CPUs from.  Maybe NEC found a pile of them  somewhere in Japan..

Sure the modem performance is known, however actual testing using the landlines might show some differences. That's where my concern is.

>> analogue lines are on the verge of being replaced by IP based solutions.
Are you talking about add-on services such as broadband, and not actully replacing the landlines?

Ignoring old3eyes rumour for the moment, the landline will remain supplying a broadband service from a cabinet close to the house. Telephones will either be IP or connect via adapters. The line circuit A-D performance of these adapters usually isn't as good as a conventional telco exchange for modem and fax use.

Also with the few Orcon serviced residences the lines are actually VoIP but instead of having a PAP2 unit (VoIP - analogue) at home these lines are serviced by from the exchange where the lines are hosted.

The service may be VoIP but the lines are still analogue in that case. You still get something different to a traditional G711 codec performance.

I think (think is the keyword) you will find modems won't perform as well on this service - the last mile is copper but it's just moving the PAP boxes from home to a hosted environment.

It solves other issues as well such as homes with multiple outlets, reduces the risk of misconfiguration etc.  I think it's an interesting solution, however, you don't get the full feature set of VoIP. 

Back on topic, if the OP can't get any help from anyone else, PM me and I'll see what we can setup for you at work.

It's not a question of being obstructive but why is the device being locked into obsolete technology? Why not pass the data to whatever solution works locally? There are already security alarm systems running into problems as houses convert to other telco suppliers.

Oh I didn't say it solved any problems, or if it's better than a PAP box. I just said it's not the same as an analogue line and it may cause problems with modems. The rest you list are natural conclusions.

Ooh, music to my ears, I can keep all my funny old phones going for a few more years yet!

VoIP is great but not the best in a power cut and pstn quality is still much better.

What ever the truth is it would be more complicated than a CPU change. The E had processor upgrades during its life but AFAIK the K is completely different. Replacing the K with E RLU would have made sense 15 yrs ago but where would the parts come from now.
