NBN to remediate business connections over copper

But will lock you in for 12 months if the existing copper line isn’t up to scratch

The company responsible for building the National Broadband Network, nbn, will begin offering line remediation to business services unable to reach their committed speeds over the copper network.

Business level services delivered over Traffic Class 2 (TC-2) have a committed information rate (CIR) which effectively guarantees a connection’s transfer rate.  Typical residential services are provisioned over Traffic Class 4, which has a peak information rate (PIR) describing the “up to” transfer rate achievable over the line.

The company is already offering TC-2 services over its FTTN and FTTB network with symmetrical transfer speeds of 5, 10 or 20 Mbps.  However, according to the current Wholesale Broadband Agreement (WBA), the company is currently not committing to its Committed Information Rate — stating:

“the actual Information Rate experienced by Customer, Downstream Customer or the relevant End User, may each be significantly less than the downstream CIR and upstream CIR of the bandwidth profile ordered by Customer in respect of the relevant Ordered Product”

According to the revised WBA on its website, the company will enable customers to submit a trouble ticket to remediate the copper line.  However, nbn will also require the end user to take up the service for at least 12 months or will have to pay an early disconnection or modification fee.

NBN will charge an early termination or modification fee if customers had their line remediated
NBN will charge an early termination or modification fee if customers had their business line remediated

Increased FTTN performance objectives

nbn is also increasing its network availability operational target on the FTTN Network from 99.70% to 99.80%.  The agreement states that “operational targets are non-binding and aspirational”.

The new wholesale broadband agreement will become effective in early December 2016.

 

Widespread delays plague Multi-Technology rollout

Analysis: Some areas delayed by up to 8 months, with 290k premises delayed by at least a month

The company responsible for building the National Broadband Network has updated its rollout schedule, revealing wide ranging delays of over a month in 105 multi-technology mix (MTM) rollout areas around Australia, affecting around 290,000 premises.

These rollout areas predominantly uses the Coalition’s preferred Fibre to the Node (FTTN) technology, where the company rolls out fibre to the neighbourhood and reconnects with the existing copper to the home.  Despite promising rollouts using the FTTN technology to be faster to complete, the company had reportedly been facing issues including slow rollout design approvals from power companies who will have to power the nodes in the streets.  The reasoning behind the latest set of delays is unknown.

The areas worst affected by the delay are Cygnet in Tasmania and Mornington in Victoria, with a delay of 8 months shifting completion dates from late 2016 to mid 2017.  The is followed closely by another rollout area in Mornington, Victoria as well as South Hobart and Margate in Tasmania and Garfield in Victoria with delays of between 6 and 7 months.

The rollout in Fletcher, NSW and suburbs near Claremont, Hobart, Tasmania have been set back by around 5 months.  Another 8 rollout areas, covering around 22,400 premises in parts of Victoria, Queensland, Western Australia, Tasmania and New South Wales have been delayed by 4 months.

Another 22 areas, not listed below, were delayed by less than a month.

Analysis based on NBN Co’s rollout schedule, reproduced by Telstra on the Telstra Wholesale website.  A variety of sources were checked to confirm this information.

Shallow dive: West Coast Tasmania NBN doesn’t make sense

There’s something unusual about the way NBN is planning to service the West Coast of Tasmania.

The company is preferring to place over five thousand Australians onto an already oversubscribed network with a single point of failure 36,000 km away from Earth in favour of a fibre network without a redundant loop. Supposedly, this is more redundant.

The company originally planned to roll out a fixed line network (presumably Fibre to the Node) as well as fixed wireless in and around the townships of Queenstown, Rosebery and Zeehan. The plan was to utilise an existing fibre that already services the towns to deliver the service.

The company has since backflipped on these plans, claiming that a second fibre path is required to provide fixed-line services and such costs would be “too expensive” to build.

These are townships with existing fibre and microwave transit network, they already for 3G/4G mobile networks, plus ADSL or ADSL2+ Internet.

Does NBN seriously think dealing with issues with the satellite 36,000 km away from Earth’s surface is easier to fix than a single fibre spur network that already currently services those towns?

Could NBN consider using satellite or microwave network as the second, redundant path in case the main fibre breaks?

What’s a “Shallow dive”? Shallow dives are a content format I’m trying out. Essentially, they are shorter, more concise pieces to either summarise detailed analysis pieces I’ve written — or briefly write about topics that I don’t yet have the time to analyse in detail.  Think of them as a TL;DR of the original piece.

Analysis: Is privatising the Multi-Technology Mix the best way forward?

With almost no competition to incentivise an upgrade to its network, can NBN’s monopoly Multi-Technology Mix keep up with user demands or will it become Telstra 2.0?

Infrastructure Australia released it’s “Australian Infrastructure Plan” report today. It’s contents are not exclusively about the National Broadband Network, however, it made a number of recommendations to the Government suggesting that the NBN should be privatised in the medium term.

A bit of background: the fibre monopoly

Since the conception of the National Broadband Network, there had always been a plan and provision to sell company once the rollout is complete. With the original “full fibre” plan envisaged by the then-Labor Government, selling or not selling the fibre network at completion wouldn’t materially affect competition.

Fibre at the premises level is a natural infrastructure monopoly. Much like how water supply companies do not build competing sets of pipes for competition, fibre is effectively a pipe with limitless upgrade opportunities by simply “swapping out the equipment at each end”. It is vastly inefficient to duplicate networks for the sake of competition, and the Optus and Telstra HFC “war” in the 90s was an excellent example of how broadband infrastructure competition can fail.

There is a case for small amounts of network duplication in inner metropolitan areas. However, it becomes hard to compete (at least within the fixed-line space) with a network that’s already built to the scale that NBN would have.

Selling, or even long term (99 year) leases of the fibre network based on geographical areas would have made sense. Like water companies, telco infrastructure entities wouldn’t spend too much time duplicating each other’s network. Upgrading networks to user demands would incur minimal capital expenditure, as it’s a matter of swapping equipment at two ends. Competition will continue to exist, but only in the retail/service delivery component of the network by Internet Service Providers.

The Multi-Technology Mix

But things changed. If you haven’t noticed, the NBN is no longer rolling out fibre to the majority of premises. The Coalition Government’s policy of a Multi-Technology Mix fixed-line network creates new challenges policy makers in the future will need to deliberate carefully before pressing sell in parliament.

On the upside, a Multi-Technology Mix is an effective way to drive infrastructure competition. However, it doesn’t work when it’s being built by a single entity — especially not a Government-owned enterprise.

No incentive to upgrade, unless split up and privatised

As a monopoly, investing large sums of money on upgrading technologies like VDSL2 over copper where upgrade paths is not as simple as “swapping out equipment” presents an ongoing burden for the NBN company. As user bandwidth demand grows, many telecommunications companies would upgrade and extend their networks to meet user demand. Or else, they would risk a competitor coming in to take over their market share. That’s what happens in areas with healthy infrastructure competition — such as Hong Kong.

But like Telstra before it, NBN wouldn’t have a business case to upgrade its networks — even if user demands skyrocket. The company would stand to lose money (at least in the short-term) by investing to upgrade its network, while it would keep a steady revenue if it just maintained the network as it is and not upgrading at all! Civil costs to push fibre out further into the field to meet user demand isn’t cheap, especially when it’s done in successive truck rolls (which is what the current policy is).

We can say that the current NBN policy focuses on short-term policy objectives — lowering the short-term capital expenditure costs, while risking medium to long-term operation costs — in other words, leaving it for policymakers of the future to deal with.

Privatising the Multi-Technology Mix by its technologies would make sense — provided the necessary regulatory instruments were put in place. Consider privatisation by splitting the NBN into a FTTx, HFC and Wireless/Terrestrial entities. These three entities could lend themselves to infrastructure competition in areas where there is sufficient network overlap. In metro areas for example, failure to upgrade the copper-based VDSL2 solution used by the FTTx entity would see the threat of an adjacent HFC footprint grow to meet user demand (and vice versa).

In regional and rural areas, the viability of infrastructure competition is not immediately obvious. Improvements in fixed wireless technologies could threaten the market share of the FTTx entity, but the fixed wireless network would need to grow substantially to be of real competition. In addition, wireless and terrestrial (satellite) solutions tend to be more expensive. So is it possible to create healthy competition, or would those areas have to rely on Government subsidies to promote upgrades?

Even if competitors are identified, each of these entity would need to have equal opportunity to grow its footprint into their competitor’s existing footprint. Having equal access to things like duct and pipe, Tier 1 and Tier 2 facilities, power and potentially many more aspects is crucial before any privatisation goes ahead.

Then there’s the issue of vertical integration

Looking at the current telco market in Australia, obvious candidates with enough capital for purchasing parts of a privatised NBN would be Telstra, Optus, the TPG Group and the M2 Group. Companies like Nextgen or Vodafone could still take a share.

But all these companies I’ve listed, bar Nextgen, already hold a retail front: Telstra, Optus, TPG and Vodafone are obvious by name. M2 owns Dodo and iPrimus.

Currently, the unique nature of NBN is that it is entirely wholesale only with no vertical integration, driving substantial retail competition in the service provider front. In my opinion, this needs to stay as is. Infrastructure companies should stay structurally separated from its retail front to ensure innovation within the “service” sector and ensures equal pricing regardless of who owns the network.


Conclusion

In a privatised world without a ubiquitous network of natural monopoly (like fibre), the only way networks will meet user demand is by infrastructure competition. Infrastructure competition requires network duplication (or at least the threat of) to stimulate investment to upgrade. So the question is: do we want this duplication? Isn’t it blindingly inefficient to have networks that do the same thing being built two or three times over just to keep with user demand?

I think we’ve put ourselves in another telecommunications policy nightmare in Australia. Time and time again, successive Governments — in their short sightedness — have failed to realise the consequences of their policy decisions. The NBN was meant to solve the issue of a lack of infrastructure investment that resulted from the privatisation of Telstra. It still could, but potentially at the cost of inefficient network duplication.

Yes, I’d still argue that a Fibre to the Premises model would have been the ideal model. It would have made privatisation easier, it would have been far more elegant. But what’s done is done.

Some would argue it’s a good thing. Infrastructure competition could work well for companies who have substantial capital while also owning large amounts of existing network assets.

Currently, TPG is the disrupter in the market. The rollout of inner-city Fibre to the Basement network is a good example of what healthy infrastructure competition could look like.

So yes, in conclusion, if done correctly — splitting and selling the NBN is probably the best way forward for Australia. But as Malcolm would say, “it’s not the way we would have done it”.

What do you think?

NBN Fibre to the Node Trial at Umina Beach

nbn’s right: users probably not affected by node congestion

nbn has strongly refuted suggestions that their node’s backhaul link is already hitting capacity, and figures seem to match their assertion.

(analysis) The company responsible for building the National Broadband Network, nbn, has refuted claims that backhaul congestion is the primary cause of slow speeds experienced by users on its recently-launched Fibre to the Node network. As a matter of distinction, this is separate from the blog post I wrote 7 months ago about long-term capacity challenges faced by nbn.  In this post, we are discussing congestion issues faced by current customers.

If we examine the figures closely, there simply isn’t enough customers on each node (yet) to need to worry about backhaul congestion yet.  In raw numbers, the lucky chaps in Belmont North connected to node 10 in Belmont 7 (2BLT-07-10) had just a smidgen under 100 premises connected at the start of this month.  This is followed closely by node 5 in Belmont 5 and node 2 in Belmont 1 in the raw take-up of high 80s.

Node (ADA) ID Node premises count Currently active premises
2BLT-07-10 233 93
2BLT-05-05 247 88
2BLT-01-02 226 84
2GRK-02-11 273 83
2BLT-10-08 246 82
2BLT-07-07 210 81
2BLT-07-17 233 80

If we consider the FTTN AVC profile revealed in estimates (13% on 12/1 Mbps, 50% on 25/5 Mbps, 25% on 50/20 Mbps and 12% on 100/40 Mbps), we can consider an aggregate average downlink AVC of roughly 39 Mbps per FTTN user.  At roughly 100 per node sharing 1GE uplink fibre, even during full saturation — each user would get on average an uncontended 10 Mbps link.  That’s better than a 1:4 contention ratio — well above most, if not all, residential-grade services.

Of course, I’m not privy to NBN’s network utilisation graphs.  But I’m fairly confident that they will show in each node, there is currently plenty of buffer space.

As I’ve said in an earlier blog post, node-based congestion can really only be expected during peak times on a fully loaded node.  Without wider saturation of 4K TVs at this point in time, the entire neighborhood of 100 premises must stream at least 2 HD Netflix or YouTube video simultaneously before there starts to be congestion issues — a virtually impossible scenario.

We don’t know what may happen in the future. Perhaps when 4K becomes more mainstream, it will become an issue.  The scenario I posed was 25% of customers simultaneously streaming 4K is all it would take to congest a full loaded node.  But at least for now, it’s pretty safe to say that this particular factor is not major concern.

So if it’s not node backhaul, what is it?

It must suck to be in this situation currently.  When you have end users posting speed tests well below 10 Mbps download “consistently”, you know there is an issue somewhere. Whether it’s a sync speed issue, CVC underprovisioning, packets being dropped by nbn somewhere within the network or something else altogether — testimony given by CEO Bill Morrow at the recent Senate Estimates suggests that nbn and service providers are working through it bit by bit to diagnose.  One thing’s for sure, it’s most probably nothing to do with node backhaul congestion yet.

NBN looking for FTTdp vendors

The company responsible for building the National Broadband Network, nbn, is seeking for an expression of interest from manufacturers of “Distribution Point Units” used to power a Fibre to the Distribution Point (FTTdp) network.

FTTdp is similar to the Fibre to the Node technology preferred by the current Government.  It enables faster speeds by bringing the fibre closer to the end user’s premises (often described as “fibre to the curb”).

In its request (found online on its tenders website), the company outlines the key requirements of interfacing with nbn‘s existing GPON solution as well as being able to power the unit from the premises it services.

  • Is designed to be typically deployed at a deeper delivery point in the nbn™ network, than can be otherwise achieved through current nbn™ xDSL technologies
  • Delivers nbn™ services into the premises over a pair in the existing copper lead-in cable via an xDSL interface
  • Is powered from the premises over the same copper pair used to carry service into the premises
  • Connects back towards the Point of Interconnect (POI) via nbn’s existing FTTP GPON solution

nbn expects to use Fibre to the Distribution Point (FTTdp) technology to service areas with longer copper loop lengths where Fibre to the Node cannot ordinarily deliver minimum download speeds of 25 Mbps.

Expression of interest closes on the 22 January 2016.

NBN lets down Tasmania, again.

Tasmanian communities of Queenstown, Rosebery, Zeehan and Strahan will be forced onto an already “severely oversubscribed” satellite beam.

The company building the National Broadband Network (nbn) has revealed that they will no longer provide a fixed-line or fixed wireless solution to major settlements located along the west coast of Tasmania.

Up till July this year, nbn has released various rollout plans showing the towns of Queenstown, Rosebery, Zeehan and Strahan as candidates for the Multi-Technology Mix (MTM) and Fixed Wireless rollouts which would have seen Fibre to the Node be rolled out to the majority of premises.  The area was also expected to receive a Fibre to the Premises rollout under the previous all-fibre NBN policy.

  • Queenstown: 1,300 FTTN
  • Rosebery: 600 FTTN, 300 FW
  • Zeehan: 500 FTTN
  • Strahan: (originally planned for NBN Fixed Wireless)

However, when questioned by Senator Anne Urquhart at a Senate Estimates hearing last month — nbn‘s chief executive Bill Morrow revealed that they have re-allocated premises in those areas to be serviced by the recently launched NBN Satellite.  Citing high costs of up to $20 million to build out a second fibre path to the west coast towns, the executive said:

Because of the cost to provide fibre services in the backhaul sense to serve within the FTTN. The area only has one fibre path going out to it, and you need to have two for redundant based services. The cost—and we have looked at it a number of different times—to provide fibre out there in a different path makes it exorbitantly expensive.

The move to satellite has also been independently confirmed using NBN’s internal technology modelling.  However, the towns affected are all currently being serviced by Telstra ADSL/ADSL2+ services, with Queenstown having access to the Telstra 4G network as well.

“Severely Oversubscribed” Satellite Beams

The beams servicing this area, number 54 and 56, has also been identified by NBN’s Fixed Wireless/Satellite Strategic Review as being “severely oversubscribed” prior to the redesignation of the fixed-line footprint in July.  Adding another 3,000 premises would not improve the satellite congestion anticipated in those areas.

However, given the availability of existing ADSL/ADSL2+ services in those towns, it is unlikely that residents will switch to the National Broadband Network due to increased latency.  As revealed last monthnbn will implement a fair use policy for the NBN satellite.  While the final policy is yet to be confirmed, the first version released saw a standard quota of 75GB per month… a far cry from the current data quotas on comparable ADSL plans.

Microwave backhaul

A report written by Engineers Australia in 2010 stated that the affected towns (amongst others) were serviced by Telstra using microwave backhaul links rather than fibre at the time it was written.  However, the testimony given by nbn executives at Senate Estimates suggests that a single non-redundant fibre path has been built since the report was written.

Originally, it appears that nbn had planned to build its transit network out to Queenstown (see diagram below, published in March 2014) using a single non-redundant spur fibre path from Sheffield or Burnie.

Opinion

$20 million to build a redundant path to service ~3,000 potential customers does seem unreasonably high.  I don’t think it’s wise to go ahead to do spend that money.

However, it does beg the question why NBN cannot use their own microwave links as the redundancy path to service the west coast communities.  Given there is supposedly already a single fibre path that nbn can utilise, using microwave links as a redundancy path would surely be cheaper than fibre — right?

nbn has effectively neglected these communities. I doubt anyone who lives in an area with existing, well-established communications infrastructure like ADSL/ADSL2+ connections and Telstra 4G mobile reception would opt for a NBN Satellite connection given their smaller data allowances (compared with fixed-line DSL) and higher latency.  This is most unfortunate, given National Broadband Network is supposed to fix and improve connectivity around Australia — not offer a degraded version of it.

I’ve seen isolated cases like this in the past — people able to access existing DSL broadband but placed on the satellite… but not to this scale.  Not entire communities like this.

Yes, nbn‘s current Government policy is to build the network out “at the least possible cost”… but that doesn’t mean putting   thousands of premises into an already severely congested satellite beam!  Our former communications minister, now PM’s buzzword of being “agile” seems to be lost at nbn.  Surely as a special case, there can be alternative arrangements made for the redundant path?

Could we have gone all fibre rather than this G.Fast talk?

Did we miss an opportunity to get an FTTP+HFC rollout? Figures from NBN’s stragegic review suggest a two-stage FTTN to G.Fast upgrade could now cost more than if we just stuck with FTTP

Even before they’ve switched on a single Fibre to the Node customer — nbn, the company responsible for building the National Broadband Network, has been busy spruiking their plans to trial and eventually upgrade Fibre to the Node to G.Fast technology to the media.

However, acccording to estimates made in the company’s Strategic Review, building the Fibre to the Node network now and upgrading to Fibre to the Distribution Point (FTTdp) using G.Fast technology would have saved a mere $2 billion dollars compared with a “radically redesigned” Fibre to the Premises rollout.  Since then, blowouts in the Fibre to the Node rollout would have surpassed the said savings of $2 billion dollars.

Fibre to the Node: blowouts

The company had straight-out refused to publish a raw Fibre to the Node cost-per-premises figure in their Strategic Review. However, on page 101 of the Strategic Review, the company estimated that it will cost around $2 billion dollars to roll out 3.6 million premises using Fibre to the Node architecture.  This equates to approximately $555 — $833 per premises (assuming range of $2 — $3 billion dollars divided by 3.6 million premises).

According to the latest 2016 corporate plan, this cost has blown out to $1,600 per premises or a net increase of $767 — $1,045 per premises (excluding infrastructure lease which was not attributed to CPP in original calculations).

nbn has also increased the FTTN/B/dp footprint from 3.6 million premises to 4.5 million.  From Fibre to the Node cost per premises alone, this has attributed to a net blowout of between $3.5 to $4.7 billion dollars from Strategic Review cost estimates — potentially overriding the savings of $2 billion envisaged in the VDSL–G.Fast upgrade path.

Fibre to the Premises: better than expected?

The issue with this is of course, comparing FTTN costs with costs that we’d never know.  We will never know exactly how much a “radically redesigned” FTTP rollout would have costed — but we can make estimates:

Comparing NBN’s estimates for Fibre to the Premises (Revised Outlook) in the Strategic Review with current Fibre to the Premises, figures shows they had over-estimated the capital expenditure of the FTTP rollout by about 11%: ~$4,100 in the Strategic Review ($1,997 for LNDN plus $2,100 for the activation, equating to $4,097 — see pages 62 and 64 of SR) vs $3,700 in the 2016 Corporate Plan.  This suggests better-than-expected costs in the Fibre to the Premises rollout costs.

But it’s too late anyway

But unfortunately, the company has already invested billions into developing the so-called Multi-Technology Mix and has a task to rollout Fibre to the Node thanks much to Government policy.  These are costs that taxpayers will never be able to recover, meaning we may have missed another opportunity to rollout FTTP in the majority of the now-FTTN footprint.

As the cost of the copper-based network increases, the comparative investment in those technologies become less attractive.  Speed and capacity upgrades require installing more active equipment in the field and also extending fibre closer to the home. Thus, incremental upgrades and ongoing operating expenses on a copper-based broadband network is far greater than those on a fibre-based network where only tail equipment has to be swapped out.

If the savings in building a copper-based network are relatively small in initial capital expenditure — eventually, the economics will reverse and bite back.

Since Fibre to the Node will now span the majority of the network, the only logical upgrade path for those areas would now be FTTdp because of all the capital costs sunken into rolling out FTTN.  But don’t think for a second that it will be actually cheaper than rolling out fibre all the way to the home in the first place.


In summary, if the Strategic Review’s figures are to be trusted, we may have missed yet another opportunity to get a FTTP network, albeit “radically redesigned” in nbn‘s vernacular.  Calculations suggest it could have cost less than what the current FTTN rollout plus a G.Fast upgrade in 2020 will cost.  Plus, the company has also proved at almost every instant that they had underestimated any non-FTTP costs in the strategic review and helpfully inflated any FTTP costs higher than actuals.

What are your thoughts?  The analysis, of course, makes assumptions based on the available data.  I think it’s a real pity how it seems time after time, taxpayer’s money ends up being wasted based on a false premise in a rushed report.

NBN Fibre to the Node Trial at Umina Beach

NBN waives and caps a ton of FTTN charges

Service provider feedback forces NBN to waive new charges to be introduced with the launch of the Fibre to the Node product.

Citing concerns by some service providers, the company responsible for building the National Broadband Network has decided to temporarily waive or cap a number of new charges “minimum period of 12 months” that were originally scheduled to be introduced with Fibre to the Node installations.

Professional filter installation: capped

Amongst the charges changed is the “professional installation” charge for Fibre to the Node and Basement areas, where a technician installs a central filter at the premises to reduce copper line interference.

Initially, nbn had wanted to charge service providers and in turn, end users, a variable cost depending on the number of hours the installer took to complete the installation.  The filter installation during the initial order would have had a base cost of $160 and the company would charge a further $75/hour for every hour beyond two hours plus any additional material costs.  Filter installations requested after the initial standard installation would have cost at least $235, plus every hour beyond three hours.

nbn says that some service providers “expressed concern that the basis on which NBN Co is going to charge for Professional Splitter Installations (i.e. on a time and material basis) would make it difficult for them to establish fixed prices for their retail offers.”  The company has now introduced capped pricing at $160 and $235 respectively, and will not charge for additional hours incurred or extra materials used in the installation.

Other costs waived

In addition to the changes to the filter installation, nbn has waived its right to charge service providers a number of other ancillary charges.  A number of service modification have been waived entirely such as equipment removal, modifications and repair.  These were originally charged at $75/hr for a minimum of 3 hours.  Service management charges for missed appointments, late cancellations, incorrect technician callouts and so-called “no fault found” callouts have also been waived for the FTTN and FTTB network.

NBN Fibre to the Node Trial at Umina Beach

Initial NBN FTTN areas delayed to test processes

Last week, I reported that the activation of around 164 thousand NBN Fibre to the Node premises had been delayed by up to 4 months.

nbn, the company responsible for building the National Broadband Network, confirmed the delay to technology publication Delimiter.  The company says they have deliberately chosen a slower activation approach as it “allows us to test our own processes and systems and to identify any issues along the way.”
