What is ADSL?
In DSL technology (short from Digital Subscriber Line), there are several subdivisions, but the one that is today mostly used is so called ADSL - Asymmetric Digital Subscriber Line. Its main characteristic is asymmetry, what makes it the most interesting DSL solution for both residential and business users.
Attribute of ADSL technology is higher speed for download than for upload, what fits real demands of users who usually much more download than upload.
Majority of interesting applications for network users are asymmetric (video on demand, access to distant LANs, access to Internet, home shopping, etc.), where user take much more information from network and send less information to network. That asymmetry makes ADSL as perfect solution for these applications.
What is needed?
At first, that is the ADSL equipment (ADSL modem, splitter, cables and adequate installation software), needed for connecting your computer to Internet.
Splitter is device which should be connected to the end of your telephone line and its purpose is to split DSL signal from signal for signal of common telephony or ISDN.
Splitters make that copper pair is available for both data transfer with high connection speed and for telephone conversation using the same line at the same time.
DSL terminal device (DSL Modem / DSL Router) which should be connected to computer and DSL line, that is splitter, serves for data transfer.
There are two types of modem/routers:
- the one that connects to computer by USB, and
- the one that connects to computer by network card
The second option is more practical if you intend to connect to Internet several computers by DSL, and for that you need DSL router.
DSL routers are available in different versions – beside the basic functionality, majority of them have got switch integrated, so computers from local network can be connected to them directly.
