ADSL2 and ADSL2+ What are they, how do they work and how is it different from the ADSL Internet connection?

the market of broadband is one of the ones that has grown the most in recent years, and they also continue with the growth advances where they have been favored with a large number of standards approvalsall this has led them to renovate all infrastructuresthus becoming one of the most profitable markets today.

In the case of ADSL service great progress has been made, this is how thanks to the second generation of this ADSL2 and ADSL 2+ service you can get one higher browsing speed because there has been a increase in bandwidth.

For its part, this ADSL2 and ADSL2+ technology are currently one of the best known and used throughout Spainthis is how here we are going to explain a little more about what it is about and how this new service works that comes hand in hand with ADSL internet service.

What is ADSL2 and ADSL2+ and what are these Internet connections for?

These two technologies ADSL2 and ADSL26 have been designed primarily for improve ADSL internet speedso these two systems are able to offer maximum connection speeds of 8 and 24 Mbps downwhile 1 and 2 Mbps upload. Although generally upload speeds are often limited.

Therefore, the main objective of these two systems is to be able to take advantage of the entire ADSL infrastructure, which will work from it. In this case you simply have to install a special device in the switchboard, This allows this same service to be offered in a simpler way to a larger number of users.

In the event that the client has a high-end router and last generation then you will not need any other device to perform this facility. Since, in general, these devices are configured so that they are capable of support these two technologies. In the case of ADSL2 on many occasions it is offered for hire an IP television systemthis is how it is responsible for assigning a bandwidth available for various types of digital services.

How does ADSL2 improve on classic ADSL connections? Main differences

The ADSL2 It has been a technology created with the main objective of improve classic ADSL connections, this in order that users can begin to experience a better service and better performance. For this, it is mainly based on improve what is the speed of the connection and other aspects necessary to be able to ensure optimal operation. Therefore, here we are going to show you the main differences between the two and how ADSL2 improves the classic ADSL.

Improved transfer speed

Without a doubt, the main objective of this new technology is to improve the transfer speed with respect to that of classic ADSLfor this it is in charge of expanding in great magnitude the frequency used for data transfer down to the 2.2 MHz. In this way, this may allow you a data download at a maximum speed of 24 Mbps in long-range telephone lines, all this in the case of ADSL2+.

While, in the case of the ADSL2, can reach reach a maximum download speed of up to 12 Mbpsand regarding the frequency used for the data transfer downstream can become 1.1 MHz.

Network health monitoring

no doubt that the new ADSL2 system takes care of improve the devices that provide this type of serviceand which are intended to be able to add a large number of facilities that allow diagnostics in a much simpler way. either for what is the phase of the installation of the same, for its use or for the improvement of the service.

Therefore, with these diagnoses made you can get to measure what is the signal-to-noise power of the line, loop attenuation, and signal-to-noise ratio (SNR). All this will allow you to track the current connection statuswhich will help ensure that it is in a optimum performance at all times. as well as power assess the state of the infrastructure and if the terminal is capable of offer better data transfer rates.

Adaptive connection speed

Another improvement that can be found with respect to traditional ADSL systems, is that these traditional systems They usually have problems when increase transfer ratebecause it generates a high crosstalk produced by telephone line cables.

Therefore, ADSL2 service is responsible for improving all these aspects, for this it carries out a monitoring of the amount of distortion and noise in the mediumthis is achieved by managing to vary transfer rate as high as possible without the need of lose the quality of the connection and thus avoid possible errors.

In this way, the speed adjustment that is made is done transparentlywhere some mechanisms are used that allow the change of transfer speed without generating failures in the system when processing the different information.

Improved power management

ADSL2 has introduced into your system a large number of improvements over the traditional system with the purpose of decrease energy consumption by everyone providers of this broadband service. All this tries to optimize in a better way all energy resources wasted by traditional ADSL.

In other words, previously with this service, the teams in charge of promoting this type of connection had to be connected all the timenow with this new technology they can add one or two rest times so that these devices are not forced to work continuously. Without a doubt, this becomes a economic savings for all or almost all providers.

In order to achieve this, it is necessary to use two power modesboth of L2 and L3where L2 power mode will be in charge of regulate the energy according to the traffic that circulates between the connection of the client and the supplier. While L3 modeis the one who will take care of set a sleep state more lethargic to be introduced when the connection is not being used for a long period of time.

Data buffer optimization

Optimizing data buffers is another of the most important best of this system, since this is what will make the ADSL2 can have one higher transfer speed. This is because the data buffers they are in charge of store frames In case of the line is congested. Meanwhile in classic ADSL this buffer is fixedso it does not show responsiveness in the moments of congestion.

In this way, the ADSL2 take advantage of the spaces that are not used by the buffer in order to get a download speed increase of up to 50 Kbps and in turn allows the bandwidth reserved for the telephony service to be used in data transmission managing to obtain an upload speed of 256 Kbps.

Previously the time for making the initial connection between provider and client was 10 seconds with classic ADSLwhile with the ADSL2 is time has been able to decrease up to 3 seconds.

Improved speed with multiple phone lines

Is new ADSL2 technology allows you to use more than one telephone line for provide this connection service to a single terminal, which allows you to improve the speed of it. For all this, it includes in its standard different ATM standards regarding the specifications from “Reverse Multiplexing for ATM” or also known as IMA.

This is what ends up allowing demultiplexing of the different ADSL connections of the different telephone lines are brought to a single device, What will increase drop rate considerably. Therefore, from the ATM layer all data received through the sublayer What is it provided by IMA to be able to process the data that arrives from the physical layers of ADSL.

All this leads to each terminal dealing with all these telephone lines as a single connection. In order to do this, it is done by means of a series of sub protocols that come from the desynchronization of ADSL2 physical devices, where they treat the information received from devices when these have different latencies.

List of the best ASDSL2 and ADSL2+ providers in Spain and their rates

You may be thinking of upgrade your broadband connection service, either to pass you to the new ADSL2 and ADSL2+ technology. However, for this you need to know What are the providers that currently offer this type of service in Spain?.

It is important to mention that so far only There are three companies that offer this service and which we are going to present to you below:

wanadoo

The first company we introduce to you is wanadoo, which launched this ADSL2 offer This service recently came out. Nevertheless, wanadoo Has failed offer this technology in all its expression, since many of its users have stated that they still they do not receive the speeds contracted in the service, so that actual speeds are well below.

This is how until now it has not been possible to meet a client who achieves receive the 20 megabytes offered by Wanadoo, as connections are barely reaching 15 megabytes. The main objective of the company is to offer speeds up to 20MB/ 1MB, but in case the client does not achieve synchronize these speeds discounts will be offered for not receive the service in its entirety.

Among the services offered in their plans, you can find a section for the web and mail where the customer can enjoy 15 accounts of 100 Mb, a POP3 access and 100 Mb of web space. For this it offers a router with time port with connection 24 hoursand best of all is that does not require a commitment of permanence for hiring of the same.

superband

superband is another of providers of this type of serviceit is opening several own plants with the aim of power offer a better service. This is because you have had many inconveniences in recent months with France Telecom, company with which he works today. Nevertheless, superband is characterized by offering the lowest rates in the market.

Thus, superband offers a ADSL2+ speed up to 20MB/1MB through a Wi-Fi router equipment with a schedule of 24 hour connection. Among added services you can find what that’s 15 pop accounts of 100 MB and a web space of 50 MB.

Jazztel

Jazztel is one of the most popular companies in all Spain and which became the first to offer this type of ADSL2+ broadband connection system. Due to this and its great popularity in the country, it has been presenting Some inconvenients at the time of install that servicesince being so many customers who want to join themhave presented many limitations on processing.

This has undoubtedly caused Complaints about delay in servicessince it usually happens a long time from when the service is requested until it begins to work. In the case of the speed offered by Jazztel is also 20 megabytes / 1 megabyte, where to use a USB router or modem of any of these two models: Huawei SmartAX MT882 or Comtrend 536.

Unlike the other two companies, it is that in this case customers will be able to enjoy connection speeds between 16 and 18 megabytes as long as they meet near the power stationsotherwise this will decrease according to the distance between the supplier and the client.

knowing the three main operators of this service in Spainand the speeds offered by each of them, surely you will want to make one of their services. So if you are interested hire any of these rates you can do it entering this link where can you find all the necessary information so that you can make the services of some of these three Internet providers.

Is it worth hiring ADSL2 or is it better to upgrade to FTTH (fiber optics)?

Being able to choose between ADSL2 or fiber optic connection It will depend mainly on the needs of each of the users. That is, if you are one of the people who does not require a very fast speed to make use of your Internet connection then the best thing is that you get one ADSL connection.

It is important to note that although this ADSL second generation technology offers higher connection speeds it is still less than those offered by the systems of optical fiber. Also, the speed received by ADSL2 services is not real, that is, the user always You will receive a lower speed than the one contracted. Otherwise, what happens with the FTTHwhere the user will receive a real speed, namely, if you contract 50Mbps you will receive 50 Mbps.

In case you need a Internet connection to watch streaming content to work with multimedia content or download Torrent files the best thing is that you do an FTTH servicewhere the operators will allow you hire speed that you think necessary either 50 Mbps, 100 Mbps, 500 Mbps, 600 Mbps or up to 1 Gbps.

Therefore, with this service fiber optic connection you will be able hire the speed you think is necessary for what you need. This means that if you have contracted an ADSL service at home and you want to update it, the best thing is that you go directly to fiber optics, there you can enjoy a better browsing speed when using the service.
