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

In Austria, ADSL2+ is offered by all copper-line service providers, with major ones being Telekom Austria, Tele2 Austria, UPC and Silver Server.. The majority of DSLAMs are capable of supporting ADSL2+ technology while older equipment is limited to ADSL.
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).
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 FUP. 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.
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.
Bosnia and Herzegovina
ADSL2+ is offered by the following operators: BH Telecom (website) nationwide and Logosoft in Sarajevo, Zenica and Tuzla.
In the Serb Republic entity, m:tel DSLAM network devices show ADSL2+, however m:tel still continues to provide speeds up to 10240/640 according to their website.
In Croatia, ADSL2+ is offered by all service providers, with major ones being H1 Telekom, T-Com, Optima Telekom, Amis Telekom, Iskon Internet and Metronet telekomunikacije. 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. All service providers provide a flat-rate model with unlimited traffic. Amis Telekom, VIPNet, H1 Telekom, Iskon, Optima Telekom, and Hrvatski Telekom offer IPTV.

In the Czech Republic as of 2008, the ADSL/ADSL2+ coverage is above 90% of all fixed phone lines, however maximum attainable rates vary. In many locations, and even in major cities such as Prague or Brno, the maximum speed does not even reach 4 Mbit/s because of the telephone cabling quality. Pricing plans of the biggest ADSL provider, Telefónica O2 Czech Republic, range from €23 per month for 8,192/512 kbit/s to €27 per month for 16,384/768 kbit/s.
There is also a wholesale offer for alternative ADSL providers, nevertheless the end-user price in such case does not differ significantly from that of O2. Less than 5% of all ADSL customers use the offers based on the wholesale offer.
There are about half dozen alternative ISPs that offer data plans utilizing the so-called LLU. In this case the final price is about 25% lower than that of O2. However the LLU is typically available only in large cities. The list of LLU providers includes the following compaines:
- GTS Novera
- České Radiokomunikace – 8,192/512 kbit/s for 699,- CZK (cca €27), 20,480/1,024 for 899,- CZK (cca €35) (pricelist)
- Volný/Telekom Austria Czech Republic, bought by Dial Telecom in December 2008 – 8,192/512 kbit/s for 699,- CZK (cca €27), 16,384/768 kbit/s for 929,- CZK (€36) (pricelist)
You can check whether there are LLU offers available on your phone line. The site also estimates the maximum attainable speed on your line.
All major DSL providers in Denmark offers ADSL2+, including TeliaSonera, 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 classified as villages or smaller. TDC provides triple play.
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 1 Mbit/s. A map detailing the availability of ADSL2+ has been made available. ADSL2+ is also offered by Elisa Eesti AS. Speeds range from 5 Mbit/s to 24 Mbit/s.
ADSL2+ and triple play solutions are offered by the major DSL providers (including Elisa Oyj and TeliaSonera) in certain areas. Usually maximum download speed when using ADSL2+ is 24 Mbit/s and upload speed 1 Mbit/s. Also Nebula, SuomiCom, DNA, KPO, JNT, Finnet and many other ISPs provide ADSL2+ connections.
ADSL2+ and triple play solutions are offered by the major DSL providers (including Orange, SFR, Free and Bouygues Telecom) except in some rural areas. Usually maximum download speed when using ADSL2+ is 24 Mbit/s and upload speed 1 Mbit/s. 30% of population is actually limited to 2 Mbit/s due the DSLAM's lower bandwidth (ATM collect – G.HSDSL links aggregating).
Deutsche Telekom (DTAG) as former monopolist controls the majority of all end user telephone lines. It has rolled out ADSL2+ technology and now deploys VDSL2 outdoor DSLAMs in urban areas. Many of the providers listed below are reselling services provided by DTAG or at least rent the last mile from it. Some exceptions are regional providers who offer to connect houses in their areas for around 8000 euros (e.g. Netcologne, Willytel, Wilhelmtel).

- Magnet Business offers ADSL2+ services with its roll out to many exchanges in urban areas over the incumbents (eircom) copper local loop. 10 Mbit/s downstream and 1 Mbit/s upstream 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. Its ADSL2+ Services are also available to residential customers, along with its fibre to the premises service which is available in certain residential developments.
- Smart Telecom offer ADSL2+ products to residential customers who are connected to any of their growing network of unbundled exchanges. 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 voice over IP, 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 30 July 2008 BT Ireland launched 24 Mbit/s service on its LLU exchanges.
- Eircom In April 2009 Eircom, the Irish incumbent Launched 24 Mbit/s and 12 Mbit/s Annex M Services on 100 of its 1,200 exchanges with another 200 smaller exchanges to follow by year end 2009. In January 2010, eircom launched a 24 Mbit/s ADSL2+ Residential Service using Annex A Profile on the same 100 exchanges. By year end 2012 they finally reached 300 exchanges.
Most minor and major Italian operators, now offer rates up to 20Mbit/s.
This offer is theoretical. To actually get the maximum rate, the customer needs to be attached to an ATM DSLAM, served by an STM-1 (fiber optic) converter, that isn't also serving more than two DSLAMs contemporaneously. This kind of network setup is now available almost anywhere, even in small towns.
Since 2007, Telecom Italia is operating Gigabit Ethernet DSLAMs, offering 7, 10 and 20Mbit/s rates. The, still partial, coverage of the GBE solution, is meant to spread to and cover most cities now served by ATM DSLAMs rated at 7 Mbit/s.
GO , 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. A number of lines are still using ITU G.992.1 Annex B but the company will upgrade the line on demand.
T-Home and One are the two ISPs which offer ADSL2+ in Macedonia, with download speeds up to 20 Mbit/s and upload speeds up to 1 Mbit/s. T-Home and On.net can deliver their services across the country. T-Home offer IPTV services, with high definition television (HDTV) and established an optical network to the users in part of the capital city of Skopje in 2010.
The biggest ADSL provider, Moldtelecom is deploying ADSL2+(G.992.5 Annex A) throughout all Moldova. Their current broadband offer tops at 20 Mbit/s download 1 Mbit/s upload for $20 (€15). The new ADSL2+ infrastructure is available since December 2009. Interdnestrcom (Transnistria) – other provider's broadband offer tops at 8 Mbit/s download 512 kbit/s upload for $35 (€26) since 1 April 2010.

Clix was the first operator providing ADSL2+ technology in 2005, later followed by Portugal Telecom brands and Vodafone. These operators offer download speed up to 24 Mbit/s with 1 Mbit/s up. All three operators offer a triple play solution (telephone, Internet, and TV) with TV over IP. In 2009 Portugal Telecom accelerated fiber-optic install on the main cities of the country providing download speeds up to 100 Mbit/s.
The biggest ADSL provider, Romtelecom (group of Deutsche Telekom) is deploying ADSL2+(G.992.5 Annex A) mainly in medium and larger cities. Their current broadband offer tops at 20 Mbit/s download 1024 kbit/s upload. The new ADSL2+ infrastructure is available since Q2 2008.
The Moscow ADSL provider MTS offers ADSL2+ for some phone lines in Moscow (not all equipment on the lines is upgraded from older ADSL to ADSL2+ yet) up to 20 Mbit/s downstream 896 kbit/s upstream.
The global ADSL provider Rostelecom (offers its services under the brand Domolink) offers ADSL2+ for some phone lines in Moscow and Moscow region up to 15 Mbit/s downstream.
Most minor and major Slovak operators, now offer rates up to 20Mbit/s. The base speed is set at 5Mbit/s with upload speed up to 512kbit/s. The price starts at €11.99 for FLAT. Deutsche Telekom AG (owns 51%) (Slovak brand – Telekom) with state (owns 49%) control all end user telephone lines. Telekom in 2012 upgraded capacity of DSLAMs and is preparing for VDSL2 technology. July 31, 2013 was announced by Telekom to offer VDSL from 1 September with speed up to 50/5 Mbit/s. Also it will be offered by alternative ISPs.

In the UK, various companies are deploying ADSL2+, with O2 and Tiscali (Talk Talk Group) having the most extensive coverage as of February 2009.
The majority of ADSL2+ providers use a process of local-loop unbundling (LLU) by connecting a customer's phone line directly into their network, bypassing BT's core network, to provide ADSL2+ lines. The availability is then limited only by the number of exchanges unbundled by each telecom operator: it is not necessary to wait for BT Group.
BT Group, which owns nearly all the POTS infrastructure across the country, began rolling out ADSL2+ based services in Jan 2008 as part of its 21CN programme to upgrade its core network. BT and are on track to enable exchanges serving around 90% of UK premises during spring 2013.
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.

2006 also saw Internode trial – and subsequently release – ADSL2+ Annex M services for business users. 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. The program was cancelled in April 2008 by the Labor government, citing coverage issues.
In January 2008 Telstra lifted 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. Seven months later, Telstra Wholesale signed agreements with People Telecom and PacNet to make ADSL2+ tails available to those customers.

At Sept 2009 about 50% of the approximately 1.8M New Zealand homes were within reach of ADSL2+. With the onset of local-loop unbundling, competing Internet service providers such as Compass, Callplus, VodafoneNZ and Orcon have also installed ADSL2+ DSLAMs in Telecom's exchanges. On 13 March 2008, Orcon announced that it was offering ADSL2+ services to the general public.
