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 Mbit/s upstream depending on the distance from the DSLAM to the customer's home. Image File history File links No higher resolution available. ... Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ... In information technology downstream refers to the transfer speed (usually that of an internet connection) by which data can be sent from the server to the client. ... This article is about the unit of information. ... A megabit per second (mbps or mbit/s) is a unit of data transmission equal to 1,000 kilobits per second or 1,000,000 bits per second. ... Siemens DSLAM SURPASS hiX 5625 A Digital Subscriber Line Access Multiplexer (DSLAM) allows telephone lines to make faster connections to the Internet. ...

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. This article needs to be wikified. ...

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

Modems that support g.Bond Not a lot of modems out there currently support g.bonding. Therefore, to help those who are looking, below is a list of modems/routers that support g.bonding. It would be nice to see some 4, 6 and 8 ADSL2+ Line g.bonding modems here. Know of any, add them in.

ADSL2 Annexes ADSL2 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.

Lebanon

Ogero has started to deploy ADSL2+ in Lebanon in June of 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 4 GB per user on a 1 Mbit connection.^{[citation needed]}

India

India has an indicative 50 million wireline connections which are likely to grow to 500 million over the next six years because of liberalisation and privatisation. India is a fast growing telecom market, adding 8 million telephony subscribers each month (in 2007). Wireline services are provided by the incumbents (MTNL and BSNL) and the new private sector players (Airtel, Tata, Reliance, Shyam and HFCL). In addition India has ISPs like VSNL and You Telecom. [BSNL][41] 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+. India has over 2.5 million DSL subscribers, 80% of which are on the ADSL2+ standard. Indian DSL penetration has been limited by the absence of personal computers in Indian homes. Only an estimated 3 million of the 200 million Indian homes own a personal computer. Most Government plans to increase PC penetration in recent years have failed. Reasons for failure include the cost of a PC, language, computer illiteracy etc. India has its own homegrown DSL standard called HDVSL (Hi defn video over subscriber line) which successfully addresses this problem. The HDVSL standard operates a 36 Mbit/s duplex ethernet link - and the HDVSL modem has a direct connection to a display eliminating the need for a terminal or client altogether in the home. The HDVSL modem also acts as a set top box and dsl modem substitute for home internet connectivity on a television screen. HDVSL has an estimated 250K homes under deployment in India and China - mostly over a fourth wire - the intercom wire (which is used for inbuilding security systems). The HDVSL standard is likely to see large scale commercialisation in 2008. In addition, there have been several startups which attempt to provide thin client and remote computing based solutions. These include Novatium, Nivio and Primetel - all of which have credible Tier I Venture Capital backing.
