If you maintain a broadband connection, you no doubt have heard of DSL. “DSL” itself stands for the term, “Digital Subscriber Line,” which is a form of high-speed Internet connection that uses the wires of a regular telephone line to link consumers to the Internet. Connections can also be made through a local-area network connection via a cable linking.
Benefits of Using Broadband DSL
Advantages of associated with using reliable broadband DSL include the following:
- You can leave the Internet connection open while utilising the phone line for making and receiving calls.
- DSL speed is greater than that of a regular modem.
- A DSL connection does not normally necessitate the need for new wiring as you can make use of the phone line that is already installed in your office or home.
While the above listing certainly highlights the benefits of DSL, there are some disadvantages associated with the connection too. The connection receives data at a faster rate than it sends it, all which is fine for streaming data but not so good for delivering correspondence in the form of e-mails.
DSL service also works the best when it is in close proximity to a DSL provider’s main office or central facility. You need to be in close contact with the main office in order to obtain a stronger signal for connectivity. A DSL broadband connection is usually preferred in urban settings as the service is not available everywhere, especially in remote or certain suburban spots in a city.
DSL Types of Transmission
Following are DSL transmission types:
Asymmetrical Digital Subscriber Lines (ASDSLs) are used, in the mainstream, more by residential customers than businesses. This form of broadband transmission is often used by surfers who are in the habit of receiving a good deal of data but do not often send much online information to friends or business associates. That is because ADSL is designed to provide faster broadband speeds downstream versus upstream. The subscriber line is ideal for phone usage as the phone can be used when data is being transmitted over the line.
Symmetrical Digital Subscriber Lines (SDSLs) are used by businesses for such online services as video conferencing – a form of media that requires substantial bandwidths going both downstream and upstream. Offshoots of this kind of line include high data rate digital subscriber lines (HDSLs) and very high data rate digital subscriber lines (VHDSLs).
Cable modem services allow cable operators to feature broadband utilising the same kinds of coaxial cables that supply audio and images to a televisions set. Most of the cable modem that are used are external devices that feature two links – one that is connected to the computer and the other connected to a wall outlet for cable. Transmission speeds can vary, with most speeds beginning at 1.5 Mbps+.
Fibre Optic Technology and Wireless Connections
Recent and fast broadband connections are made through fibre optic technology and through the use of wireless broadband, which links homes or businesses to the Internet using a radio connection. The link is secured between the service provider and customer location. Satellite connectivity is available too.
