Connecting to the network with an ADSL internet connection has now become a common way of using broadband to surf the web quickly.
How an ADSL internet connection works
ADSL technology is one of the possible broadband internet connections which allows high browsing speeds compared to the traditional connection via the normal telephone line connected to an analogue 56K modem.
In the case of the ADSL line, an abbreviation that derives from the English wording "Asymmetric Digital Subscriber Line", it starts from minimum theoretical speeds of 640 kb per second which rise according to the contract stipulated with the access provider and the quality characteristics of the local network.
Peculiarity of the ADSL line is that of being asymmetrical, i.e. with a different speed for sending and receiving data in order to have a greater flow of incoming data which is the one most requested by most users who use the Internet mainly to surf and to download and not also to upload files to remote servers.
The advantage of the ADSL line is that it can be easily activated on existing telephone systems using a single twisted pair (shielded two-wire copper cable) without having to separate the data flow from normal voice communications.
This passage on the same wire of two different types of signal is made possible by the different band used which is cut by a low pass filter for the frequencies up to 3400 Hz used for the transport of the voice, to be applied on each socket to which a telephone fax machine or alarm switchboard, while the higher frequencies are intended only for the digital flow of data transmission.
Depending on the bandwidth required, each twisted pair can serve variable numbers of telephone users.
In addition to the normal ADSL subscriptions in the areas reached, it is also possible to sign ADSL 2+ contracts that allow you to reach 20 megabytes in discharge as well, with the indispensable condition of being very close to the telephone exchange.
