At last... Statistics New Zealand says:

The number of broadband subscribers in the six months to September 2007 overtook the number of dial-up subscribers for the first time ever, Statistics New Zealand said today.

Broadband subscribers continued to increase – up 14.4 percent in the six months to September 2007, to reach 829,300.

However, this growth rate has slowed from an increase of 28.6 percent in September 2006 and 18.5 percent in March 2007. Subscribers with dial-up connection fell 8.6 percent from March 2007, down to 675,800.

The number of broadband subscribers grew from 9 per 100 inhabitants to 19.6 per 100 inhabitants in the two years ended September 2007, while the number of dial-up subscribers per 100 inhabitants fell from 21.2 to 15.9. Of the additional 10.6 broadband subscribers per 100 inhabitants, half switched from dial-up and the remaining half were new subscribers.

There was a 47 percent increase in the number of Internet service providers reporting that the cost of international bandwidth had been a barrier to growth in the past two years.

The Internet Service Provider Survey is a census of all Internet service providers in New Zealand and is conducted every six months.

Now the ISPs and telcos should work based on the fact that broadband is not going bac to the cave where it came from, and they have to up th plans, bandwidth and allowance.

... and Theresa said that our low broadband penetration was due to dial up users liking their free local calling and cheapness.

And a lot seem to be forgetting the fact dialup internet will die a rather sudden death when the NGN rollout starts and there is no such thing!

Wasn't the NGN rollout supposed to start by now? If so, then there would already be customers who no longer have access to dialup if the network could not do dialup over VoIP

There are no NGN residential customers yet.

Dialup dying off due to NGN rollout is very unlikely.

Hmm, I thought NGN = no more analoge lines which means no more dialup? So of course dialup will slowly die, about time if you ask me. :)

POTS will still be available.

So is telecom investing in more new PCM switches or VOIP switches to provide these continued POTS services? Its my understanding (and telecoms NGN briefing diagrams clearly show) that the NGN will be only providing POTS via a VOIP ANA in the home, not distributed as POTS from the curb.

Do the cabinets have enough room for a VOIP ANA and DSL filter set for all subs including the ISAM and incubent MDF's

Did I miss something?

The only exchange based POTS service will be to remain will be <500line exchanges, and presumably these will be upgraded to VOIP based operation.

In which case Dial-up is not going to work presumably?

Which will rule out Dial-up for those customers as well.

What will happen to those on >5km copper loops where broadband will never reach?

I have many rural friends in exactly that predicament

I presume that when replacing <500line switches they will not be installing PCM gear, I mean do the still make it (joking), but if the rest of your network has moved on to IP then it makes sense to use a VOIP driven remote line card arrangement, end result is dialup still works for those folks. Just because its VOIP does not mean its not G.711 PCM.

cyril7: Hi, Would they not be concidered on <500line switches.

Yes, in most cases that would be true I suspect.

cyril7: I presume at some point even from a cabinet where current subs are on a classifed >500line switch that long lines will be serviced only on POTS however presumably from a ANA of some description at the nearest cabinet.

What does ANA stand for?
Presumably something different than ATA?

VFX supports G.711u and G.711a but no way could I get dial-up to work through it.

Do you expect that Telecom's Chorus unit will attempt to offer dial-up support once the new gear is installed?

Hi, I edited my post, sorry, but still ANA analog network adaptor, same as ATA no diff in this conversations instance. If you are using G.711 which is 64kb/s PCM then should work just as before. ADSL2 allows for QOS based reservatioin of high performance bins, ie VOIP traffic can be put down a seperate carrier set to ensure QOS. If ADSL2+ is your only service and all subs are in the <2km loop then I think the performance will be quite different to current ADSL service in respect to VOIP service.

But really for customers in the cabnetisation region, if Telecom are to deliver POTS via VOIP to your door then why would you chose dialup as opposed to broadband from the box providing ANA serivce on the side of you house.

As for customers on long loops if fed from a VOIP loop surely this would not be feed from a DSL line but rather the fibre behind that.

Thanks for explaining it all so well Stephen, that's great, I can now answer the questions that are thrown at me every so often

cyril7: ...for customers in the cabnetisation region, if Telecom are to deliver POTS via VOIP to your door then why would you chose dialup as opposed to broadband from the box providing ANA serivce on the side of you house.

Certainly! In that case you would be crazy to choose dialup

cyril7: As for customers on long loops if fed from a VOIP loop surely this would not be feed from a DSL line but rather the fibre behind that.

This is the situation affecting many of my friends. In some cases, I don't think fibre goes anywhere near their exchange, but it would be a microwave link.

So, what you are saying is that these customers can continue to use dial-up because the G.711 codec at the exchange will have the same interface to the POTS line as it does now, just that the method of backhaul interconnection will be different due to the IP-based architecture that is being rolled out?

Correct me if I'm wrong obviously. I just want to get this straight in my head so I can answer the questions clearly.

Cheers,
Grant.

Hi, All is speculation obvioulsy, the only details from Telecom was their 22 Nov Wholesale customer briefing, where they clearly showed home phones attached to a router rather than finding their own copper path back to the cabinet.

So one assumes that the cabinet will not have a POTs capability and if the exchange behind each cabinet has been removed its a reasonable assumption.

One comment on what I mentioned before regarding seperate bins in ADSL2 being reserved for high priority service, that may be slightly wrong, on rereading my ADSL2 notes there is a technology in ADSL2 called Channelised Voice over DSL (CVoDSL), if implemented this uses reserved bins at the top of the upstream and bottom of the down to transfer upto 4 voice circuits seperate to the main ATM/IP based traffic. However on rereading the notes its not for VOIP but for pure PCM, which means a PCM switch is needed behind the DSLAM to support it. I have not seen any ADSL2+ CPE that support it.

That said, if cabnetisation reduces loop length to less than 2km, then normal interleaved DSL delays can be removed, as I understand it ADSL2 has the potential for dealing with this in a better manner anyway.

But yes one assumes that Telecom will not replace any PCM switches, rather place VOIP interfaces between the IP network and those remaining <500line switches.

Speculation, unless someone in the know is willing to explain more
