ITU G.992.5


ITU G.992.5

ITU G.992.5 is an ITU (International Telecommunication Union) standard, also referred to as ADSL2+ or ADSL2Plus.
Commercially it is notable for its maximum theoretical download speed of 24 Mbit/s.

Technical information

ADSL2+ extends the capability of basic ADSL by doubling the number of downstream bits. The data rates can be as high as 24 Mbit/s downstream and 1.4 Mbit/s upstream depending on the distance from the DSLAM to the customer's home.

ADSL2+ is capable of doubling the frequency band of typical ADSL connections from 1.1 MHz to 2.2 MHz. This doubles the downstream data rates of the previous ADSL2 standard of up to 12 Mbit/s, but like the previous standards will degrade from its peak bitrate after a certain distance.

Also ADSL2+ allows port bonding. This is where multiple ports are physically provisioned to the end user and the total bandwidth is equal to the sum of all provisioned ports. So if 2 lines capable of 24 Mbit/s were bonded the end result would be a connection capable of 48 Mbit/s. Not all DSLAM Vendors have implemented this functionality. ADSL2+ port bonding is also known as g.998.x or g.Bond ADSL2 AnnexesADSL2 has multiple modes for DSL providers to offer better services for different needs. Below is a list of available features based on ADSL2 specs from the ITU standards.

Deployment

Europe

Belgium

ADSL2+ so far is available in the major cities of Belgium and some smaller ones.

[http://www.scarlet.be Scarlet] has ADSL2+ in its portfolio. The package is called Scarlet ADSL20. The download speed is capped at 20 Mbit/s and upload is as high as 1 Mbit/s.

[http://www.edpnet.be EDPNet] also offers ADSL2+. The Max24 Dyn and Max24 Fix subscriptions deliver speeds up to 24 Mbit/s downstream and 1 Mbit/s upstream.

[http://www.belcenter.com Belcenter] : The Max2+ subscriptions deliver speeds up to 20 Mbit/s downstream and 1 Mbit/s upstream.

For all its ADSL products Belcenter is a wholeseller of Scarlet's ADSL network.

[http://www.e-leven.be E-Leven] offers an ADSL2+ subscription at 20 Mbit/s downstream and 1 Mbit upstream with 30 GB data volume included. For 9,90€ extra per month, the volume limit is lifted and a Fair Use Policy is applied. E-Leven's ADSL2+ offering is available only in areas where they have their own ADSL2+ DSLAMs.

[http://www.dommel.com Dommel] offers 3 new ADSL2+ subscriptions, with speeds up to 24 Mbit/s downstream and 3 Mbit upstream. As of January 21st, these products are available in the city center of Leuven. In the course of 2008 cityconnect products will become available in and around more Belgian large cities (such as Gent, Hasselt, Genk, Oostende, Liege, Charleroi, Antwerp, Mons, Brussels and Kortrijk).

[http://www.yabu.be Yabu ADSL] offers 3 ADSL2+ subscriptions (speeds up to 24 Mbit/s downstream and 3 Mbit upstream). These connections are available in Leuven, Kessel-Lo and Sint-Truiden. The covering area will be expanded to Antwerp, Berchem, Genk, Gent, Hasselt, Lier, Mechelen and Ostend in the summer of 2008. In the course of 2008 these connections will be available in more Belgian cities.

Croatia

In Croatia, ADSL2+ is offered by all service providers, with major ones being T-Com, OT - Optima telekom, Amis Telekom, Iskon and Metronet telekomunikacije. Currently all DSLAMs are capable of supporting ADSL2+ technology. The foremost reason for introduction of ADSL2+ was introduction of IPTV service by T-Com, which required major bandwidth increase.

Czech Republic

In Czech Republic the ADSL/ADSL2 coverage is above 90%, however maximum attainable rate very varies. Unfortunately in some locations, and even in huge cities like Prague or Brno, there are some locations which can't handle more than 4Mbit/s because of telephone line's quality . Internet plans are following:

Telefónica O2 Czech Republic - 8192/512 kbit/s for 399,- CZK (cca 16 EUR), 16384/768 kbit/s for 832,- CZK (cca 33 EUR).
There is also wholesale offer for alternative ISPs, unfortunately their offer is not very different from O2's so it's not very popular (less than 5% customers [http://www.dsl.cz/clanky-dsl/clanek-1134/600-000-ADSL-pripojek%3A-duvod-k-oslave%2C-nebo-ke-smutku%3F] )
More interesting are alternative ISPs which offers plan on their LLU [http://en.wikipedia.org/wiki/Local_loop_unbundling] , then the price is sometimes almost half from O2's. However it's only available in very few cities with huge population. We've three LLU ISPs:
GTS Novera [http://www.gtsnovera.cz]
České Radiokomunikace [http://www.radiokomunikace.cz]
Volny/Telekom Austria Czech Republic [http://volny.cz]

If you've a LLU available can be verified here [http://www.dsl.cz/adsl-internet?pct=dostupnost] and it also estimates maximum attainable speed.

Denmark

In Denmark, as of 2006, all major DSL providers offer ADSL2+, including Tele2, TDC, Fullrate, Cybercity and Perspektiv Broadband. As of 2007, approximately 90% of the country is covered, although maximum bandwidth (24 Mbit/s) is available in and around the cities, that is not classifieds as villages og less.50 Mbit has been introduced as of January 2008

Estonia

ADSL2+ together with a triple play solution is deployed on a large scale by Elion Enterprises Limited.Download speeds are, depending on package, up to 16 Mbit/s (8 Mbit/s when watching DTV) and upload speeds are up to 768 kbit/s.A map detailing the availability of ADSL2+ has been made available [http://tv.elion.ee/leviala_kaart.html here] .ADSL2+ is also offered by Elisa Eesti AS. Speeds range from 5 Mbit/s to 24 Mbit/s.

Hungary

In Hungary, since mid-2006, multiple telecom companies have started offering ADSL2+ services. As of July 2007, T-Com, the biggest Hungarian ISP, is silently upgrading its customers' ADSL connections to ADSL2+, although with no speed changes.

Ireland

Magnet Business [http://www.magnetbusiness.ie] has led the way with its ADSL2+ roll out over the incumbents (eircom) copper local loop. 10Mb Download and 1 Mb uploads is a typical offering for their Business Broadband. Major cities initially (Limerick, Dublin, Waterford, Portlaoise, Cork, and Galway) as Magnet rolls out its unbundled exchange project.

Smart Telecom offer ADSL2+ products to residential customers who are connected to any of their growing network of unbundled exchanges. Currently the company have service in 37 Irish exchanges covering large areas of most of the major cities in Ireland. They have an entirely IP-based NGN (Next Generation Network) built around Multiple Service Access Nodes MSANs and carrier grade VoIP, multimedia and other services are provided using Thomson SA Cirpack Softswitch technology. This equipment provides the end user with both high speed broadband internet access and normal POTS service (i.e. a dial tone) all over the same entirely IP-based infrastructure.

BT Ireland On 30th July 2008 BT Ireland launched 24Mb service on its LLU exchanges.

Italy

Tiscali [http://www.tiscali.it] is the only one offering theoretical 24 Mbit/s ADSL2+, although Telecom Italia, Wind Telecomunicazioni and expecially Fastweb [http://www.fastweb.it] are offering "real" 20 Mbit/s.

Malta

GO [http://www.go.com.mt] As of July 2008, started to offer ADSL2+ speeds between 8 Mbit/s and 20 Mbit/s download speeds in direct competition with local cable internet supplier OnVol [http://www.onvol.net] . A number of lines are still using ITU G.992.1 Annex B but the company will upgrade the line on demand.

The Netherlands

As of October 2005 several wholesale DSL providers ( [http://www.bbned.nl bbned] , Tiscali, [http://www.kpn-wholesale.com/ KPN Bitstream] ) have ADSL2+ coverage on more than 50% of fixed phone lines in the Netherlands. As of September 2007 coverage is optional for 75% of all landlines, with about 1% of all connections having the option for Annex M (newest DSLAMs).

Norway

As of 2006, all major DSL providers in Norway offer ADSL2+, notable are [http://www.dataguard.no DataGuard] , Telenor, Tele2, NextGenTel, Mimer and Ventelo.

Portugal

Clix was the first operator providing ADSL2+ technology in 2005 , latter followed by Portugal Telecom brands and Vodafone.These operators offer Download speed up to 24 Mbit/s with 1 Mbit/s up.Clix and Portugal Telecom also offer a triple play solution (Telephone+Internet+TV) with TV over IP.

Romania

The biggest ADSL provider, Romtelecom (group of OTE) is deploying ADSL2+ mainly in larger cities. Their current broadband offer tops at 20 Mbit/s download 1 Mbit/s upload. The new ADSL2+ infrastructure is available since Q2 2008.

United Kingdom

In the UK, various companies are deploying ADSL2+.

BT Group, who own nearly all the POTS infrastructure across the country plan to launch ADSL2+ based services from early 2008 as part of its 21CN program to upgrade its core network. The first to market with an ADSL2+ product based on 21CN are Entanet [http://www.enta.net/] .

Alternative operators currently use local loop unbundling to provide ADSL2+ lines. Therefore the availability is limited by the number of exchanges unbundled by each telecom operator in a certain area.

Such operators include:
* AAISP [http://www.aaisp.net.uk/] have been trialling ADSL2+ since June and aim to launch services in September 2008.
* ADSL 24 [http://www.adsl24.co.uk] have launched their range of [products | http://adsl24.co.uk/broadband_24mb.php] based on the BT Group/Entanet network.
*Be Unlimited [http://www.bethere.co.uk] is rapidly expanding their service of up to 24 Mbit/s downstream and 2.5 Mbit/s upstream across the UK, and have recently overtaken Bulldog in number of unbundled exchanges. O2 [http://broadband.o2.co.uk] own Be Unlimited and also provide broadband using their network.
*Bulldog Broadband [http://www.bulldogbroadband.com] Provided an ADSL2+ service using the Cable and Wireless Network, however since Tiscali's takeover, no new customers can sign up for this service.
*Easynet now owned and sold by Sky [http://broadband.sky.com] is the largest ADSL2+ provider in the country with 1,154 exchanges unbundled as of October 2007. UK Online also use Easynet's backbone
* [http://www.cerberusnetworks.co.uk/int_internet.html Cerberus Networks] are providers of business-class ADSL2+ services in the UK. Services have up to 24 Mbit/s downstream line rates and 2.5 Mbit/s upstream.
*Virgin Media [http://www.virginmedia.co.uk] Now supports ADSL2+
*TalkTalk (Carphone Warehouse) uses ADSL2+ on their LLU enabled exchanges. However the service is currently capped at 8 Mbit/s downstream. As with all ISPs, the actual throughput speed obtained in practice is usually somewhat lower still.
*Eclipse Internet [http://www.eclipse.net.uk/] is currently trialling an ADSL2+ service to select customers. It is unknown at this time what the specifics of the trial involve, or how many exchanges are currently unbundled for the service, only that the full 24Mbit/s downstream will be available.
*Orange customers have reported the un-advertised introduction of ADSL2+ (and ADSL2) on LLU lines in some areas during April 2008, although speeds are currently capped at ADSLmax levels.

*O2 [http://www.o2.co.uk/] Provide an ADSL2+ service.

*Zen Internet Ltd Provide a ADSL2+ service on their Rochdale LLU exchange.

BellSouth has deployed the service in limited areas of its 9 state region.

BCE inc. - [http://www.bell.ca Bell Sympatico] Service is available in parts of Ontario and Quebec (primarily in the main cities), expanding to most of the DSL service area during 2008.

Bell Aliant - [http://www.aliant.ca] Service is available in selected areas of Nova Scotia, New Brunswick, Newfoundland & Labrador and Prince Edward Island, subject to market requirements and technical feasibility. [cite web | title = BELL ALIANT INDUSTRY ADVISORY| publisher = Bell Aliant | date = 2007-03-16 | url =http://www.aliant.cdn-telco.com/atia-4m.htm | format = HTML | accessdate = 2008-03-22 ]

VIC Communications - [http://www.vicip.ca] Service is available in selected areas of Ontario, subject to the market requirements and technical feasibility. ADSL2 is currently being deployed in select areas to offer IPTV delivery, and higher access speeds.

TELUS in Alberta and British Columbia, Canada; have began the process of activating their networks (03/2007).

[http://www.gwi.net GWI] has deployed the service in areas of Maine and New Hampshire.

[http://www.colbanet.com ColbaNet] has deployed the service in specific COs in Ontario and Quebec. ADSL2+ DSLAM provided by [http://www.versatek.com Versa Technology]

[http://www.embarq.com Embarq] has deployed the first ADSL2+ speed of 10Mbit/s down with 1 Mbit/s up in the Las Vegas area starting on 17 September 2007, with other areas to follow as ADSL2+ capable equipment is available in nearly all Embarq service areas.

The independent telephone companies and rural carriers of North America probably have the highest total number of ADSL2+ subscribers collectively as they are currently using such technology to deliver the "triple play" voice, video and data services in order to compete with the RBOCs and cable companies with their ILEC and CLEC footprint.

Sogetel is one of the independent phone compagnie in Québec to use this to deliver Triple Play.

Guatemala

Telgua in Guatemala has deployed services across Guatemala City and nearby zones, its deploying ADSL2+ in other cities and now operates the largest ADSL2+ network in the country. Deliver speeds capacity up to 1 Mbit/s downstream and 256 kbit/s upstream, with commercial at 512 kbit/s downstream and 128 kbit/s upstream.

Oceania

Australia

Most of Australia's cities now have ADSL2+ enabled on their exchanges. ADSL2+ services are provided outside the regulated broadband requirement of the national provider Telstra, so are enabled in areas primarily where there is high interest. Current service providers of ADSL2+ in Australia are:

*aaNet
*AAPT
*Adam Internet
*Amnet
*EFTel
*Exetel
* [http://www.hotkey.net.au Hotkey Internet ]
*iiNet
*Internode
*Netspace
*OntheNet
*Optus
*Primus Telecom
*Soul Pattinson Telecommunications
*Telstra BigPond
*Total Peripherals Group (TPG)
*TPG Internet
*TSN Communications
*Westnet

In 2006, Optus announced that it would sell its ADSL2+ network wholesale to other ISP providers. This is currently the most promising option for widespread coverage of ADSL2+ in Australia as the cost to service providers may be prohibitive with many ADSL2+ DSLAMs in each exchange. This move may provide a much wider coverage with cooperation from participating providers.

In 2007, OPEL Networks was awarded government funding (which has since been withdrawn) to assist with a rollout of broadband in regional areas. Along with wireless broadband, the project will see the rollout of further ADSL2+ DSLAMs to be made available on a wholesale basis. [cite web | title = Broadband Access and Choice for rural and regional Australia | publisher = OPEL / Elders | date = 2007-06-18 | url = http://www.futuris.com.au/images/presentations/presentation_38.pdf | format = PDF | accessdate = 2007-07-14 ] The program was cancelled in April, 2008.

In some areas where Telstra has rolled out ADSL 2 capabilities. They have created sub exchanges, such as the Kellyville exchange, which third party ISP have minimal ports to allow their customers ADSL 2 capabilities.

New Zealand

Telecom New Zealand deployed its first ADSL2+ exchange in March 2007, and started deploying more after consultation of locations. With the onset of local loop unbundling, competing Internet service providers such as ihug and Orcon have also trialled ADSL2+ DSLAMs in Telecom's exchanges.

On 13 March 2008, Orcon [http://www.orcon.net.nz/informme/service,blog/category,19/item,547/ announced] that it was offering ADSL2+ services to the general public. A [http://www.orcon.net.nz/coverage/ coverage map] is also available for Auckland suburbs.

As of 24th April 2008 ADSL2+ is available to customers in certain areas of Greater Auckland, however, very few ISP's are currently offering ADSL2+ plans.

As of 2 August 2008 ADSL2+ in Christchurch, Halswell, connection off the Hillmorton Exchange. No announcement by Telecom.

Africa

Egypt

TE Data has announced the launch of ADSL2+ service with speeds up to 24Mbit/s and they have used their wide coverage all over Egypt in order to avail this service in 99% of the land lines, building on its unique relationship with Telecom Egypt and being the largest ISP in Egypt regarding the international bandwidth available, which was clear when it was the only operating ISP during the famous marine cable cut during February 2008. while LINKdotNET had deployed ADSL2+ on a normal copper line at 5 Mbit/s, 8 Mbit/s, 12 Mbit/s & 24 Mbyte/s being the first to offer beyond the 2 Mbit/s & also providing the highest in the country. LINKdotNET claims that it has "the fastest Internet access package in the Middle East". Currently, TE Data and LINKdotNET are the only providers who provide ADSL2+ in Egypt because of their use of Alcatel Dslams.

Libya

[http://www.ltt.ly LTT Company] has begun providing this service in September 2007, it works fine, but the speed has not been increased yet, it is still 256 kbit/s download, and about 128 kbit/s upload.

Lebanon

Ogero has started to deploy ADSL2+ in Lebanon in June 2007. Months after, it is still facing technical problems, and more than 3/4 of Lebanon is still not covered. The local incumbent telecom "Ogero" does not allow "fair competition" between providers because the state monopoly has the prices fixed. The cost of installation is around 55,000 L.L ($36.66) and the standard internet fee is 35,000 L.L ($23.33) at 128 kbit/s. Maximum speed obtainable with the ADSL 2+ in Lebanon is 1 Mbit/s download but that is divided between several users. Also download data is limited to around 5 GB per user on a 1 Mbit connection.Fact|date=December 2007

India

[BSNL] [http://www.bsnl.co.in] offers ADSL2+ Broadband under brand name DataOne with speeds up to 8 Mbit/s Download. MTNL offers ADSL2+ Broadband under the Triband brand name. Airtel has around 750K subscribers on a mix of ATM and ADSL2+.TTML and VSNL also provide ADSL2+ and speed is up to 2Mbit/s although telecoms and Internet service provider speed claims have regularly proved false. India has over 2.5 million DSL subscribers, 80% of which are on the ADSL2+ standard. In India, ADSL2+ will need to compete with the home grown and government supported HDVSL standard which supports 36 Mbit/s download speeds.

Hong Kong

Hong Kong's largest internet service provider "Netvigator" provides 18 Mbit/s downstream (1 Mbit/s upstream) of ADSL2+ broadband Internet connection.
