I dont think the UFB plan has all 4 fibre cores going back to a higher level exchange, only to the local splitter cabinet (which logically would be a current FTTN cabinet or other), but not any higher up the loop.

As Don has mentioned most FTTN cabinets have a 180core (or there about) cable back to the exchange, 32x180 sounds like 5k5 subs which we know there are only around 300 subs per cabinet based on the current layout (some double door cabinets obviously are capable of twice that) so theres more than enough capacity for a FTTH GPON layout with plenty of spare cores for p2p for SMEs or individuals prepared to pay.

There's also nothing stopping them from putting the ONT in the FTTN and then just using 1 shared core back to the exchange.

cyril7:
Is there anything stopping the LFC's from buying/leasing dark strands from Telecom? Either way remeber this is Vector for Auckland build, Telecom can still get other areas


As I understand it nothing, but at what cost, this is the crunch, I see citylink have now released GigE transport at a more competitive rate based on recent changes in the landscape, hopefully T will follow.

Cyril

I remember the original RFP stated that LFCs would be required to buy existing fibre if a competitive price could be negotiated, and would be allowed to lease fibre or ducts if they were available. Not sure what the priority was for leasing, as opposed to buying, legacy plant but I would say ducts would have to allow sufficient capacity to be economic as well as potentially allowing pre-connectorised fibre to be pulled through for distribution runs at least.

Edit: I'm hoping the Auckland rollout will be mostly home-run fibre, so at least one core per subscriber would be patched at the cabinet and run all the way back to the exchange (or Central Office). Vector might do that because it gives ISPs more flexibility to sell new services and centralises moves/adds/changes. Telecom already seem to be committed to installing splitters mid-span into cabinets. Either way, the money invested in getting power to cabinets is wasted so I wonder whats the cost difference on active vs passive cabinets? I suspect much of the cost is in planning...

Yeah thats the basic theory of Telecom's current FTTN, whereas FTTP puts the network terminal at the premises and only needs splitters and/or patch panels at the distribution cabinet -- no electronics in cabinets at all.

Perhaps some agreement has to be reached with Telecom to run down their copper loops and gradually migrate areas over to the FTTP network. Telecom's stake in FTTP doesn't need to be ownership of the whole network in the monolithic sense that has been the case up till now, but for example it could be as a nationwide layer 2 network operator that can sell wholesale services to ISPs including its retail division. This will be possible once they have VoIP and IPTV ready to market.

A question I would be interested in having answered would be whether Vector still have included the requirement the Government legislate that Telecom must migrate to the fibre as Vector rolls it out.

If it is still included in their proposal, who are they suggesting pays for the CPE and run to the fibre?

My personal impression is that the Government needs Telecom to structurally separate whether they are given any of the fibre rollout or not. Structural separation would hamstring their ability to compete against fibre.

ascroft: Who has VOIP and IPTV ready to market?


VoIP - WorldxChange, 2Talk, TelstraClear just to name two I know of, and I know there's heaps others.

IPTV - iSky, AppleTV, FetchTV just to name 3 I know of.

Applications are quick to sort out if you have the bandwidth and cash just to get it done.

I could get a commerical IPTV solution up and running within 6 months if I had the cash to just bring in the resources that I needed.  This stuff has all been done before by other people.

10:  The challenge is doing it in a larger scale than the small developments that have been done already, in a profitable way that can be replicated in a way that the juganorts like Telecom can sell.  Is that possible?  No idea.  Just the systems that are needed to provision that sort of thing are mind boggling as I'm sure they'd want it all integrated into existing systems that their call center csr's can provision the same way they do anything else.

The problem with that is the integration costs may very quickly chew up all the profit long before they see a return.  In the mean time the technology moves on to a point where people want the next thing that they then have to integrate in to their systems.  GoTo 10.

IPTV is fairly simple from a tech viewpoint, there are a number of turn-key solutions on the market already. The biggest blackhole of time and money is getting the content from studio's and networks. This is one of the reasons why it takes companies like SKY to push IPTV as the little guy has little chance of getting the content people want legally




Most problems are the result of previous solutions...

My personal view is that the only voice offering on fibre should be wireless with femtocells. I only want one handset with all my contacts in one place (oh with home locator billing smarts of course)

Fixed voice belongs to the dark ages...... :-)

Just a small note - the GPON split for UFB is 1:24 not 1:32

Your femtocell has to plug into the fixed network at some point.... VoIP is not always fixed to the network but everyone needs the choice of how to use the network, including running their own nanocells.

You cant mandate that ATAs and faxes will suddenly become illegal or that children should all be given iphones at the age of 5. The ubiquitous POTS phone has its uses, which includes failover FXO ports for VoIP systems.

An really good question, but still we need SOME competition. We don't need the sort of destructive competition thats quite possible. Structural separation should have happened long ago, but Telecom never proposed to fully separate — weren't they going to keep the copper assets with Telecom Retail? I think properly separating Chorus would allow them to sell both fibre and copper services to whoever needs them, including Telecom Mobile and various internet providers who will pay for backhaul with geographic diversity. I guess Chorus would take some adjustment before they were ready to sell dark fibre.

savag3: Just a small note - the GPON split for UFB is 1:24 not 1:32

I understood the advertised Northpower CIF allowed even 1:64 split without contention problems? You would still factor in the attenuation for 1:32 or 1:64 splits into the power budgets with a bit of empty space on the splitters.

I am talking about running on fibre - not POTs running copper. Can faxes even run on fibre?
