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 up to 3.5 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 (which was 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 download and twice the original upload speed. Not all DSLAM Vendors have implemented this functionality. ADSL2+ port bonding is also known as G.998.x or G.Bond

ITU-T Spec	Description
G.998.1	ATM-based multi-pair bonding: A method for bonding of multiple DSL lines to transport an ATM payload beyond the rate/reach capability of a single DSL loop. This protocol allows the bonding of 2 to 32 pairs and supports dynamic removal and restoration of pairs without human intervention.
G.998.2	Ethernet-based multi-pair bonding: Provides a method for bonding of multiple DSL lines for Ethernet transport. This recommendation builds on the IEEE 802.3ah-2004 methods and extends Ethernet transport over other xDSL technologies, including ADSL.
G.998.3	Multi-pair bonding using time-division inverse multiplexing: Details a method for bonding DSL lines using time-division inverse multiplexing (TDIM). This recommendation uses IEEE 802.3ah handshake for pair discovery, parameter negotiation, and setup. It also allows the hitless addition and removal of pairs and the fast removal of a pair upon pair failure.

Deployment

Europe

Belgium

ADSL2+ has a coverage of 85% nationwide. Initially, ADSL2+ was used to support IPTV, this is still the case if VDSL2 isn't available. Speeds are limited at 12 Mbit/s. Belgacom's reference offer is called BROBA 2. Smaller ISPs use the BROBA 2 network, as well as providers who have their own ADSL2+ equipment.

There are a few other providers who have their own equipment installed in some cities, availability is therefore narrow:

Destiny NV offers an ADSL2+ subscription for professional use, with speeds of up to 24 Mbit/s downstream and 1 Mbit/s upstream.

Dommel offers three ADSL2+ subscriptions, with speeds of up to 24 Mbit/s downstream and 3 Mbit/s upstream (annex M).

EDPnet offers two ADSL2+ subscriptions at 24 Mbit/s downstream and 1 Mbit/s upstream with 100 GB data volume included. They are called ADSL Home (dynamic IP) and ADSL Office (static IP).

E-Leven offers ADSL2+ subscriptions at 20 Mbit/s downstream and 1 Mbit/s upstream with 60 GB data volume included.

Scarlet The package is called Scarlet ADSL20 No limit. The download speed is capped at 20 Mbit/s and upload is as high as 1 Mbit/s, the download volume is based on a F.U.P.. There are several smaller ISPs that use the services of Scarlet. Scarlet's reference offer is called BRUO. Belgacom bought Scarlet, one of the conditions was to sell the BRUO-network to a third party. Most likely, it's Mobistar.

Tele2/KPN Belgium offers ADSL2+ subscriptions, the maximum speed is limited at 12 Mbit/s downstream and 1 Mbit/s upstream. There is no download limit.

Bulgaria

In Bulgaria, ADSL2+ is offered by the national telecom operator VIVACOM. Speeds up to 12 Mbit/s downstream and 1 Mbit upstream. Available almost everywhere DSL is offered. Compare all internet packages here.

Croatia

In Croatia, ADSL2+ is offered by all service providers, with major ones being H1 Telekom, T-Com, 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.

Almost all service providers offer ADSL2+ subscriptions at speeds up to 20 Mbit/s downstream and up to 768 Kbit/s upstream. Also, at all service providers, one can subscribe to a flat-rate model, which includes unlimited traffic.

Czech Republic

In the Czech Republic the ADSL/ADSL2+ coverage is above 90% of all fixed phone lines, however maximum attainable rate varies. Unfortunately in some locations, and even in huge cities like Prague or Brno, there are locations where maximum attainable rate does not even reach 4 Mbit/s because of the telephone lines' quality. Pricing plans for the biggest ISP, Telefónica O2 Czech Republic, are as follows:
Telefónica O2 Czech Republic - 8192/512 kbit/s for 475,- CZK (cca 19 EUR), 16384/768 kbit/s for 713,- CZK (cca 28 EUR).
However to get the final price you have to pay, you also have to add the price for the fixed line itself. The cheapest price plan that has to be ordered together with the ADSL data plans, called O2 Mini, costs 356,- CZK (cca 14 EUR). The O2 company plans to offer Naked DSL in a near future and is currently running pilot tests of the technology modifications needed.

There is also a wholesale offer for alternative ISPs, unfortunately the end-user prices are not very different from O2's and the ISPs do not invest much in advertisement, so it's not very popular. Currently only less than 5% of all ADSL customers utilize the offers based on the wholesale offer [1]

Some alternative ISPs also offer data plans utilizing LLU. In that case the summary price (for the fixed line and ADSL data plan) is about 25% lower than the O2's summary price. However the LLU is mostly available in large cities with lots of inhabitants only. There are three LLU ISPs:

• GTS Novera
• České Radiokomunikace - 8192/512 kbit/s for 699,- CZK (cca 27 EUR), 20480/1024 for 899,- CZK (cca 35 EUR) (pricelist)
• Volný/Telekom Austria Czech Republic, bought by Dial Telecom in December 2008 - 8192/512 kbit/s for 699,- CZK (cca 27 EUR), 16384/768 kbit/s for 929,- CZK (36 EUR) (pricelist)

You can check if the LLU offers are available on your phone line. The site also estimates the maximum attainable speed on your line.

Denmark

In Denmark, as of 2006, all major DSL providers offer ADSL2+, including TDC, Telenor, Fullrate, and Perspektiv Bredbånd. 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 here. ADSL2+ is also offered by Elisa Eesti AS. Speeds range from 5 Mbit/s to 24 Mbit/s.

France

ADSL2+ and triple play solutions are offered by the major DSL providers (including Orange, SFR and Free) except in some rural areas.

United Kingdom

In the UK, various companies are deploying ADSL2+, with O2 / Be Unlimited[33] having the most extensive coverage as of Feb 2009.

The majority of ADSL 2+ providers use a process of LLU local loop unbundling by connecting a customers phone line direct into their network, bypassing BT's core network, to provide ADSL2+ lines. Therefore the availability is only limited by the number of exchanges unbundled by each telecom operator, rather than when BT Group plans to roll out its 21CN programme to an exchange.

BT Group, which owns nearly all the POTS infrastructure across the country, is currently beginning to roll out ADSL2+ based services as part of its 21CN program to upgrade its core network and catch up with the already extensive coverage from O2 / Be Unlimited, Sky / Easynet and others.

Such operators include:

• Aquiss which were early adopters of the BT Group network solutions, starting ADSL2+ trials from October 2007 with national rollout following shortly afterwards.
• Andrews and Arnold Supports ADSL2+ on BT's 21CN exchanges^[1], also running a trial based on Be Unlimited's wholesale LLU service ^[2].
• ADSL 24 have launched their range of products based on the BT Group network.
• Be Unlimited [34] is rapidly expanding their service of up to 24 Mbit/s downstream and 2.5 Mbit/s upstream across the UK, and have now overtaken Sky/Easynet with 1,217 unbundled and 28 pending as of Feb 2009.. O2[35] own Be Unlimited and also provide broadband using their network.
• Bulldog Broadband [36] Provided an ADSL2+ service using the Cable and Wireless Network, however since Tiscali's takeover, no new customers can sign up for this service.
• Demon/THUS have implemented the "Pro" range of products which utilise ADSL2+ for faster download and upload speeds.
• Easynet now owned and sold by Sky[37] is the one of the larger ADSL2+ provider in the country with 1,154 exchanges unbundled as of Feb 2009. UK Online also use Easynet's backbone
• 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 [38] Now supports ADSL2+. However, this is to be seen as supplementary to their own network, which utilises xDSL over fibre-optics. Virgin Media came about as a result of mergers between Telewest, NTL & the subsequent takeover of the Virgin Mobile business, with Sir Richard Branson assuming the role of CEO of the combined business.
• TalkTalk (Carphone Warehouse) uses Opal Telecoms ADSL2+ on their LLU enabled exchanges. Offering the chance to go up to 24Mbit/s with their new "Speed Boost" add-on. As with all ISPs, the actual throughput speed obtained in practice is usually somewhat lower still.
• Eclipse Internet [39] uses ADSL2+ for all home and business customers. It is unknown at this time whether the service supports Annex M (faster upload), only that the full 24Mbit/s downstream is available. Eclipse use the BT21CN network.
• Gravity Internet are a business ISP who offer ADSL2+ services up to 24Mbps based on BT 21CN network.
• Karoo - ISP of Kingston Communications supply ADSL2+ up to 24Mbps since 2008 - in the Hull Area
• MacAce.net offer up to 24Mbps broadband via BT's 21CN network specifically tailored to support customers who require Mac OS X technical support.
• NewNet [40] Supply 24meg & 40meg ADSL2+ with Unlimited data transfer services on 10 South Coast exchanges since August 2007
• 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 [41] Provide an ADSL2+ service using the Be Unlimited Network (o2 uk Own Be Unlimited)
• Plusnet [42] a Bt PLC subsidiary. Rolled out a full ADSL2+ service on 21st October 2009.
• Uno Provide ADSL2+ services via multiple LLU providers with capped and unmetered data transfer.
• UK Free Software Network were part of the initial trial of the BT WBC platform for ADSL 2+ services and began offering ADSL 2+ to customers commercially from the date it was first available. UKFSN also offers ADSL 2+ LLU services where available. ADSL Bonding is offered via the BT platform.
• Zen Internet Ltd Provide an ADSL2+ service on their Rochdale LLU exchange, 3 other local exchanges and via 21CN across the UK as of 19/10/2009.
• The Phone Coop [43] is a cooperative that now offers LLU. Users become members of the cooperative and thus can receive dividend on the operating surplus.

Australia's first commercial ADSL2+ service was launched in 2005 by ISP Internode on the Agile DSLAM network.^[4]

In 2006, Optus announced that it would sell its ADSL2+ network wholesale to other ISPs. At the completion of the rollout, the Optus DSLAM network was the largest wholesale ADSL2+ network in Australia, covering over 360 telephone exchanges.

2006 also saw Internode trial - and subsequently release - ADSL2+ Annex M services for business users.^[5] In November, Telstra BigPond, Australia's largest internet service provider launched a retail ADSL2+ service to its customers. Although Telstra had been aggressively rolling-out ADSL2+ DSLAMs for some time, the company made a strategic decision to enable services only where competitors had already deployed DSLAM infrastructure, citing the possibility of a forced wholesale regime by the Australian Competition and Consumer Commission.

In 2007, OPEL Networks was awarded nearly $1 billion of government funding to assist with a rollout of broadband in regional areas. Along with wireless broadband and an extensive fibre optic transmission network, the project was to see an extended rollout of ADSL2+ DSLAMs to many regional centres.^[6] The program was cancelled in April 2008 by the recently elected Labor government, citing coverage issues.^[7]

January 2008 saw Telstra lifting the lid on its ADSL2+ network after the Australian government and the Australian Competition and Consumer Commission issued guarantees that the company would not be forced to wholesale ADSL2+ services from its 900 ADSL2+-enabled exchanges.^[8] Seven months later, Telstra Wholesale signed agreements with People Telecom and PacNet to make ADSL2+ tails available to those customers.^[9]

As of December 2008, out of 2759 ADSL-enabled telephone exchanges, Telstra has enabled 1403 for ADSL2+ services.^[10]

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 announced that it was offering ADSL2+ services to the general public. A coverage map is also available for Auckland suburbs.

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

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

As of October/November 2008, ADSL2+ is available in parts of southern Invercargill (many areas not yet confirmed by Telecom, however many active connections are in use).

As of February ADSL2+ is available in Wellington CBD from Orcon

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 Mbit/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

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.

South Africa

In November 2009 the South African service provider iBurst announced that it will offer ADSL2+ in 5 Mbit/s, 8 Mbit/s, 15 Mbit/s and 20 Mbit/s speeds. Uplink speeds will be improved to 6 Mbit/s and a 40 Mbit/s ADSL2+ to ADSL2+ service will also be offered.^[11]

Airtel has around 750K subscribers on a mix of ATM and ADSL2+.TTML and VSNL also provide ADSL2+ and speed is up to 2 Mbit/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.

Iran

Sepanta,Sabanet,Parsonline, Shatel,Datak,Laser,Asiatech,Shabdiz,Rahsa, Hamara and Fanava all provide ADSL2+ in Iran (up to 2048 kbit downstream and 2048 kbit upstream) Sometimes with high latency (up to 800 ms).

Bezeq, in November 2007, started to offer ADSL2+ service at 8 Mbit/s download with 800 Kbit/s upload. The service is currently available only to 40% of the customer, living near the switch. At the beginning of 2009, Bezeq started to deploy the NGN service that will deliver higher speeds up to all the customers by cutting the distance to the DSLAM.

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.^{[citation needed]}
