How DSL Internet Service Works
When connecting to the Internet, the connection might be via a regular modem, via a connection in the office or LAN (Local Area Network), via a cable modem or a DSL connection also referred to as Digital Subscriber Line. DSL is a connection that is high speed and utilizes similar wires like the normal telephone line. There are several advantages of the DSL. First of which is that they are capable of leaving an Internet connection open and at the same time be able to utilize the telephone line for vocal calls. The speed is a lot higher as compared to the regular modem.
Another advantage is that DSL internet does not necessarily need new wiring because the telephone line being used supports the cause. A company that provides DSL normally provides the modem as part of an installation. It also has some disadvantages like the connection being better when a person is closer to the central office of the provider. The further away one is the poorer the connection is. This service is also not available everywhere. The connection is very ideal in receiving data than it is in sending data across the Internet. Apart from these small setbacks, the DSL is very ideal because while using the phone, the Internet connection is not disturbed and also the telephone communication.
When people are informed of how telephones operate, then it is quite possible that they are aware that a normal telephone installation consists of two copper wires installed in the home. Copper wires can not only carry telephone conversation, but even more data. They can also be capable of handling a great bandwidth, as well as frequency range than a voice call demands. DSL internet access is able to manipulate the extra capacity to be able to carry information on the wire without any disturbance to the cable’s ability of carrying voice conversations.
To be able to understand how DSL connections work, there is the need to have knowledge on a standard telephone line. POTS, which is known by many telephone professionals denoting the Plain Old Telephone Service, is very ideal especially in limiting frequencies that the telephones, switches and other telephone equipment will carry. The wires are capable of handling frequencies that are close to seven million Hertz in many cases. The normal conversation tone can be carried in a range frequency ranging from 0 to 3,400 Hz. Having a DSL connection is very ideal for communicating effectively between employees in an office.
