Adsl2 - Asymmetric Digital Subscriber Line 2

If you already know about ADSL (Asymmetric Digital Subscriber Line) then you should have a general idea of what ADSL2 actually involves

. Essentially, it is a new component in the ADSL family which offers improved performance and greater downloading speeds. It enables users to surpass the previous speed of 8Mb used to transfer broadband. With ADLS2 users may download at speeds a little above 24 Mb depending on how the ADSL2 is set up. This is a significant advancement for users who frequently download or view live video streams over the internet. ADSL2 is actually compatible with all ADSL devices, making upgrade a much easier and cost effective process.

How effective is the connection?

Like most other types of internet connections there are specific factors that will contribute to lowered performance. Typically, ADSL connections rely on how well the connection is implemented between the user's house and the exchange used to enable service. Another determinant that will reduce the effectiveness of the line quality is the distance of the user's premises from the closest exchange. This essentially means the connection will deteriorate as the distance from the customer's premises increases. Consequently this will affect downloading speeds greatly and will result in customers who sign up for an 8Mb connection maintaining much less during transfer.

ADSL2 while still susceptible to the element of distance will perform much better because of the method used to accomplish its maximum potential. It is possible for users to apply for two or more lines using ADSL2. This is possible because the lines may be bonded to produce speeds up to 30Mb. Hence even if the customer lives considerably further from a normal exchange he or she will be able to obtain a fast enough connection rate once these two lines are bonded.

Is this service available in my area?

ADSL2 is a recent development and as a result is not being offered in every area that offers ADSL coverage. However, a larger number of service providers will undoubtedly begin providing the service over the next few months to a year. To determine if your provider will be establishing this service upgrade call their customer care centres which will likely have this information on hand. It is probable that there may be some developments under way to get this system in place. It is expected that ADSL2 will become the norm for the majority of ADSL users. In addition the rates the consumer will pay will not be much more expensive than the price presently being paid for regular ADSL service. The prices will get increasingly more affordable once all providers have revamped their systems to allow ADSL2 usage.

Additional Features of ADSL2 Connections

There are a few extra features that will make ADSL2 that much more enticing to the user, these will include a few of the following.

Improved rate and reach will allow users to obtain information as said before at a rate of no less than 12 Mb per second which is much more than the standard 8Mb per second currently being used by most. Also the reach for ADSL2 is an extra 600 feet enabling entirely better connections.

It allows channelization for voice over DSL.

It utilizes less power than present ADSL models by utilizing a two power management mode.

It initiates start up in 3 seconds in comparison to the 10 seconds it now requires for a regular ADSL network.

It provides bonding which will allow data to be transferred close to the speeds of most fibre optic connections and networks despite using conventional copper lines for the movement of data.
