Short-range DSL now moves to Gigabit speeds

thinkbroadband :: Say hello to new 1Gbps ITU G.9700 standard

My Comments

Just lately, the phone-line-based DSL standard has been extended to the Gigabit class courtesy of the new ITU G.9700 standard. It will take a significant amount of time before the necessary hardware is released in to the market, whether as professional-install hardware or self-install hardware.

It is primarily a way to keep the phone-line-based DSL technology alive and relevant even though the fibre-to-the-premises deployments like what is being pushed in France, Australia under a Labour government or some US cities by Google is being considered the status quo.

On the other hand, it is being pitched as a faster alternative to the short-range VDSL2 deployments that are being used in “fibre-to-the-building” or some “fibre-to-the-cabinet” setups. In the UK, they see a situation where the fibre-copper transfer point could be serving a small group of premises whether it be a street or a block of flats. On the other hand, they also suggested the technology for older buildings where it could be harder and prohibitively expensive to run optical fibre in these buildings for a fibre-to-the-premises setup.

At the moment, like with other DSL technologies, this will initially require different splitters which could make a requirement for professional “truck-roll-based” installation for these setups rather than the cheaper “self-install” kits commonly used with ADSL setups.

It will be interesting to see how this will affect the concept of deploying next-generation broadband in different areas, whether they are the target of a fibre-copper or full-fibre setup.

Can a fibre-copper next-generation broadband network be considered economical for all brownfield developments?

The recent NBN announcement put forward to the Australian people by the Coalition has determined that a fibre-copper setup is a more economical method for delivering the broadband service to already-developed (brownfield) locations than the fibre-to-the-premises setup that Labor is running with. There are some countries like the UK and Germany who run these networks, mainly with the option of full fibre deployment as an option.

The kind of talk I am raising here may work against the “preferred” idea of using existing copper infrastructure in existing condition for delivering next-generation broadband to the customer. This is because of certain realities concerning the existing infrastructure, such as a copper network that was engineered for an area that was more sparse than the current occupation density or a network that needs a lot of attention to provide reliable and optimum service.

A copper network that suited a sparse development

But I see the issue of a fibre-copper network as being area-specific for each brownfield area. Here, this could depend on the density of the brownfield area such as the concentration of multiple-tenant developments or the existence of many smaller properties since the copper network was established.

In this case, one may have to factor whether the copper network may need to be revised to cater for this increased density or whether the point of exchange between the fibre backbone and the copper network needs to be moved closer for some developments. For example, a large apartment block like some of the ones on the Gold Coast or St Kilda shoreline; or a large shopping centre like Doncaster Shoppingtown or Knox City may find that it is better to have a “fibre-to-the-building” approach with the point of exchange in the development.

Older copper networks that need extensive repair work

A copper telephony network that has been neglected by the incumbent telephony provider may need a fair bit of attention to have it work at an optimum speed for a fibre-copper broadband development. This can be more so for those networks that exist on peri-urban, regional and rural areas where there has been minimal investment in these areas.

The network may “just work” with voice telephony or baseline fax applications but may not perform as expected for a DSL application as I have written about before. In some cases, the customer may not even benefit from a reliable DSL service, and the VDSL service is most likely not to be as fault-tolerant as the existing ADSL technology.

If there is a planned fibre-copper deployment, it shouldn’t be just a case of installing a street cabinet and connecting service wires and the fibre backbone to that cabinet. In some cases, it may be about surveying the copper infrastructure for pair-gain setups, decrepit wiring / connections and other situations that may work against optimum VDSL service. Here, it may be worth dong a comparative cost analysis on remedial work for a copper infrastructure to see whether rolling out new fibre or copper infrastructure would be cheaper than doing many repairs to existing decrepit infrastructure.

This kind of work may benefit the retail Internet service providers in the reduced number of customer-service issues due to substandard service, thus providing a positive customer-service image for them.

I would therefore argue that not all copper telecommunications networks that exist in brownfield areas can be the economical basis for a fibre-copper next-generation broadband setup unless they have been surveyed and found to provide reliable service for the area concerned and the technology that is being considered.

Next-generation broadband to enable the Scottish Highlands

thinkbroadband :: Highlands and Islands in £146 million fibre boost

From the horse’s mouth

British Telecom

Press Release

My Comments

Another rural area in the United Kingdom is being enabled with real broadband. This time it is the Highlands and Islands region in Scotland.

The mighty Scots will have a fibre-optic infrastructure that will intend to pass at least 84% of homes and businesses in this area. The setup will be primarily of the FTTC (fibre-to-the-cabinet / fibre-to-the-curb) fibre-copper setup with some installations being FTTP (full fibre-to-the-premises) setups.

This £146m project is being primarily provisioned by BT but, like a lot of these projects, has a lot of public funding. There will be £19.4m pitched by BT and £12m coming from the Highlands and Islands Enterprise business group with balance being public money from BDUK (Broadband Delivery UK) and from Edinburgh.

This will be considered one of the most ambitious rural-Internet-enablement projects in the UK due to the geographical makeup of the are i.e. the hilly nature of the Highlands as well as the Scottish Islands separated by water. One of the main costs would be to run 19 undersea fibre links to the Scottish Islands that are in this district. As well, areas that are considered to be remote will be the target of a £2.5m innovation fund to get broadband in to them.

What I would see of this is that the Highlands and Islands project can he used as an example of deploying real next-generation broadband to areas that have a mixture of geographically-difficult terrains like mountains or islands.

Wales to get going with the next-generation broadband

Article

thinkbroadband :: Bangor starts the ball rolling for Superfast Wales

From the horse’s mouth

Superfast Cymru

My Comments

Wales is to be expecting a rollout of next-generation broadband, initially in the Bangor area. The article cited the establishment of fibre-to-the-cabinet infrastructure in Bangor’s High Street with one of the fibre-copper cabinets being deployed there. At the moment, the service isn’t active at that point but I would like to see the service come alive with customers connected to it very soon.

The next-generation service will be based on fibre-to-the-cabinet technology with the option of on-demand fibre-to-the-premises upgrade. Most likely the copper link would be based on VDSL2 technology. This is meant to lift the average broadband speed in Wales beyond 9Mbps.

There is GBP£425 million invested in this broadband project with the estimated rollout between now and end of 2015. There will be some focus on identified “Enterprise Zones” and “Local Growth Zones” where government wants to help stimulate economic activity or population growth.

Of course, like most rural-broadband or next-generation-broadband projects, there will be some public-sector investment. In this case, the funds will come from European Union, UK and Wales governments.

The question about rural broadband will be based on what kind of engineering conditions are needed to determine what kind of technology would be used to supply the broadband. In a lot of areas in the UK where there are estates with clusters of closely-located properties, they should look at using the FTTC technology to plant the cabinets in the estates and close to the houses rather than placing them outside the estates.

It is also worth knowing that BT are the infrastructure providers but there is importance being placed on people having their choice of retail Internet service from different retail Internet providers.

thinkbroadband :: FTTC Etherway, cheaper access to business grade broadband

My Comments

Most small businesses typically head for a consumer-based Internet-access setup which has a reduced upload rate. This can be a limitation for these businesses if they dabble with cloud-based computing, IP-based telephony or IP-based video-surveillance.

If they do want this improved upload speed, the business would have to go for an Ethernet-based service that uses the high-throughput Ethernet protocols. Such services are primarily offered as “Metro Ethernet” copper services or FTTP fibre-optic prices at a price that fewer small businesses can afford.

But BT Openreach are offering a wholesale fibre-copper service that provides Ethernet-type connectivity rather than DSL-type connectivity that is pitched at households. This is mainly for the Etherway fibre-copper setups pitched at small business and professional setups and provides the high reliability that would be expected for this kind of computing.

A question that I would have is whether the copper run is Ethernet-based DSL or Metro Ethernet which uses Category-5 twisted-pair copper cabling similar to that used in Ethernet LANs. It would encompass this ability as well as the cost-effectiveness of these fibre-copper next-generation broadband setups.

The VDSL2 technology to be tried for fibre-copper setups in France

Articles – French language

France Télécom va tester le VDSL2 – DegroupNews.com

My comments

Most next-generation broadband deployments in France’s competitive Internet market are either FTTP (fibre-to-the-premises) fibre but Numericable are running with what is called an “FTTLA” fibre-to-the-cabinet setup. This is where the copper run to the customers is a short-run coaxial cable similar to existing cable-modem setups and is based on DOCSIS 3.0 technology.

On the other hand. VDSL2 telephone-line-based technology is successfully used in Germany and the UK for the copper run in fibre-to-the-cabinet setups in those locations. Now France Telecom are intending to try it in the highly-competitive French market for cheaper fibre-copper next-generation setups. This will most likely be used as another method of covering sparsely-populated outer-urban or regional areas where the cost to deploy would be prohibitive for a full-fibre rollout.

The reason they are running with this technology is its ability to provide a “fat pipe” over telephone cable for short runs. For example, as I have seen from the article, an 800m run of telephone cable could yield a download link speed of 25Mb/s on ADSL2 technology, but could yield 100Mb/s for the same distance. Similarly a longer run which could typically achieve a link speed of 1Mbps under ADSL2 could achieve 42Mbps with VDSL2.

As I have already known, these rates are dependent on the line condition between the street cabinet or exchange and the customer’s premises. Of course, this would be delivered under sub-loop unbundling which would be part of the call for a competitive Internet market in France. Similarly, there would have to be competitive access to those street cabinets so that competing Internet providers like Free could run their fibre backbone to the newly-created VDSL2 infrastructure and reach these markets.

Personally, I would like to see any fibre-copper deployment scenarios involving rural properties like farms be looked at so that there is a proof of feasibility for bringing next-generation broadband to the farmhouse door in a reliable manner.

Customer-supplied line-filters to give VDSL2 setups the same promise of self-install as ADSL2

Article

thinkbroadband :: Openreach in technical trial to test micro-filters with FTTC service

My comments

Previously ADSL required a truck-roll to the customer’s premises to provide the service. Here, the technician installs a DSL line splitter at the line’s entry point and a socket for the ADSL modem. Now installs don’t need a technician to visit unless they are difficult or sophisticated setups like dealing with business phone systems or monitored security systems.

Typically, the customer installs a micro-filter or ADSL line splitter on each phone device and connects the ADSL modem-router to a socket that doesn’t have a micro-filter attached to it or connects the modem to the ADSL or DATA port of the line splitter. In most cases, we tend to use DSL line splitters rather than line filters at each phone socket. This can allow us to move the ADSL modem-router around as needed to suit different living arrangements or simply to relocate the wireless router for best performance.

Most fibre-copper next-generation broadband setups such as FTTC, FTTN or FTTB typically will implement VDSL2 but this is a different kettle of fish when it comes to provision. Here, a technician still visits the premises to put in a VDSL2 central splitter and run Ethernet-grade cable to where the VDSL2 modem-router would be installed.

BT Openreach are trialing the use of selected line filters and splitters as a way of providing self-installation of VDSL2-based fibre-copper setups. They are assessing these for radio and audio interference and degradation of data throughput with the commonly-used line filters attached to existing phone equipment.

Initially, the tests will be based around professionally-installed setups, but they will move towards self-install setups. It could also then give the same level of flexibility that we have enjoyed with ADSL2 equipment.

These tests could be observed by other countries and companies interesting in deploying fibre-copper next-generation broadband that uses VDSL2 technology; but can also be used as a way of justifying these setups over fibre-to-the-premises setups.

FTTP–Britain is offering it as an option in some fibre-copper areas

Article

FTTP on Demand for those who want it  | ThinkBroadband

My Comments

Some next-generation broadband services that are in existence use a fibre-copper setup like FTTC where there is a fibre-optic run to a street-side box and a short copper-cable run from the street-side box to the customer’s premises. In a multi-tenant building setup like a block of flats or a shopping centre, there may be a “fibre-to-the-building” setup where there is the copper-cable run within the development but a fibre-optic run to the development itself.

This method is being pushed as a cost-effective solution for providing next-generation broadband and has been intensified as part of the National Broadband Network debate by Tony Abbott and the Liberal-National-Party Coalition.

But BT Openreach are providing the fibre-to-the-premises technology as an extra-cost option on top of their fibre-to-the-cabinet setups in the UK. Typically the cost for providing this option would be significant and may be paid out over time.The kind of people who may initially purchase it would be larger businesses or “tech-head” computer enthusiasts who want as much bandwidth as they can.

On the other hand, most typical home and small-business users would use the fibre-to-the-cabinet setups. It is also worth noting that if a significant number of users covering a particular area choose this option, installation costs may be reduced when it comes to providing fibre-to-the-premises Internet service due to existing infrastructure.

An issue that is also forgotten about when considering “FTTP as an option” is the concept of an upgrade path. This is where a customer existing at the same premises who had a fibre-copper setup may decide to go “all-fibre” for the faster bandwidth; or a subsequent customer may move in to the same premises and go “all-fibre”. This could be supported through the use of same physical infrastructure (trenches / poles) for fibre / copper setups and a costing plan for upgrades.

The article talked of public money being used to finance next-generation broadband infrastructure and where private money should cover the cost. They were raising issues of whether public money should fund the link from the “digital hub” to the customer or whether private money should do this, and there may be a reluctance for private money to be used to provide FTTP or similar options for areas not considered profitable like rural areas or areas subjected to “redlining” based on the then-current community makeup.

The “FTTP as an option” could be seen as a compromise to please the “no-public-money” advocates when it comes to providing next-generation broadband. On the other hand, a properly thought-out universal-service obligation setup with a minimum bandwidth and a public-private funding pool could assist with making technologies like FTTP become affordable for most users. It should also support the ability to prevent “redlining” of areas when it comes to providing the next-generation broadband service.

British Telecom to touch Scotland and Wales with fibre-optic technology

Article

BT fibre rollout reaches Scotland, Wales • The Register

My Comments

British Telecom are now touching Scotland and Wales with their fibre-based next-generation-broadband services.

These will use a combination of fibre-to-the-cabinet and fibre-to-the-home deployment setups depending on the location. They wanted to have 34 exchanges in Scotland and 16 exchanges in Wales fibre-ready by 2012 with two thirds of UK premises passed by their fibre-optic network by 2014. This is part of their bid for the latest round of Broadband Delivery UK funding.

How I see it is that the upgrades are happening in the face of various local-focused rural-broadband-enrichment activity that is taking place through various parts of rural UK. In some cases, it could lead to the creation of competitive next-generation broadband like what is occurring in France where providers can compete on an infrastructure level.  It may then put BT “on notice” about the pricing and quality of their service as far as consumers and retail Internet providers are concerned due to the availability of this competing Internet infrastructure.

At least these kind of rollouts could then allow for vibrant competition in Internet service delivery in the UK.

Telephone Interview–Gigaclear UK (Matthew Hare)

In response to the latest news that has happened with Gigaclear and Rutland Telecom in relation to the Hambleton fibre-to-the-premises rollout, I offered to organise an email exchange with a representative from this company about this broadband access network.

Matthew Hare replied to my email offering to do a short Skype-based telephone interview rather than an email interview. This allowed him and I to talk more freely about the Hambleton and Lyddington rollouts which I have been covering in HomeNetworking01.info .

Real interest in rural-broadband improvements

There are the usual naysayers who would doubt that country-village residents would not need real broadband, and I have heard these arguments through the planning and execution of Australia’s National Broadband Network.

But what Matthew had told me through this interview would prove them wrong. In the Lyddington VDSL-based fibre-to-the-cabinet rollout, a third of the village had become paying subscribers to this service at the time of publication. In the Hambleton fibre-to-the-premises rollout, two-thirds of that village had “pre-contracted” to that service. This means that they had signed agreements to have the service installed and commissioned on their premises and have paid deposits towards its provision.

Satisfying the business reality

Both towns have hospitality businesses, in the form of hotels, pubs and restaurants that need real broadband. For example, Matthew cited a large “country-house” hotel in Hambleton that appeals to business traffic and this hotel would be on a better footing with this market if they can provide Wi-Fi Internet service to their guests. Similarly, these businesses would benefit from improved innovative cloud-based software that would require a proper Internet connection.

As well, most of the households in these villages do some sort of income-generating work from their homes. This can be in the form of telecommuting to one’s employer or simply running a business from home.

The reality of a proper Internet service for business was demonstrated through the Skype call session with Matthew. Here, the Skype session died during the interview and when he came back on, he told me that the fault occurred at his end. He mentioned that he was working from home at another village that had the second-rate Internet service and affirmed the need for a proper broadband service that can handle the traffic and allow you to be competitive in business.

A commercial effort in a competitive market

Matthew also underlined the fact that this activity is a proper commercial venture rather than the philanthropic effort that besets most other rural-broadband efforts. He also highlighted that there were other rural-broadband improvements occurring around the UK, including the BT Openreach deployments. and this wasn’t the only one to think of.

But what I would see is that an Internet market that is operating under a government-assured pro-consumer pro-competition business mandate is a breeding ground for service improvement, especially when it comes to rural Internet service.

Conclusion

From what Matthew Hare had said to me through the Skype telephone interview, there is a real and probable reason why the countryside shouldn’t miss out on the broadband Internet that city dwellers take for granted.
