When most people hear the words “digital subscriber line” they tend to picture a long, twisted snake with many cables snaking out from it. This sort of imagery often conjures up images of old movies with bad guys lurking around a dark corner. Fortunately that is not the case. DSL is a great service for many people, and the difference between it and conventional cable service is fairly rudimentary.
In order to get a grasp of how DSL works, it is helpful to have a clear picture of what cable services are. A traditional telephone line is simply a series of copper wires connected to one point. Digital Subscription Line (DSL) is a high-speed data transmission facility that operate much like a phone line, but provides much more functionality. This is in large part due to the fact that DSL offers a much wider range of features that phone lines typically offer.
The first major difference between DSL and a regular telephone network is that a digital subscription line uses a different frequency than does a conventional phone line. What this means is that when you place an order for DSL service you are really placing a request for a different frequency. When talking about telephone networks, it is easy to understand why people tend to get confused and think that an analog signal is a phone signal. It isn’t. It’s just that the bandwidth consumption for digital subscriptions is substantially higher.
Digital Subscriber Line can provide a very fast internet connection, and as such it is a popular choice for businesses and homes. DSL also provides much better sound clarity than a regular telephone network. Some people are still uncomfortable with the idea of subscribing to a digital service over a traditional telephone network, but it really comes down to preference. Digital Subscription Line is a viable alternative to both low speed (DSL) and high-speed (HSCSD) services.
Many people are leery of the term’ADSL’ and are more likely to opt for something like ‘cybernetically assisted telephone lines’. This is because of the misconceptions that many have about what ADSL is and what it does. For those that have no experience with these services they tend to think of them as being just like telephones. In truth, ADSL works in a completely different way from the telephone lines. A dial-up modem will dial a series of numbers, generally eight in all, until it finds an available service.
Once it has found an available service, the dial-up subscriber line will transfer information via modems, which is the way in which data is transmitted over the Internet. ADSL services are not prone to the problems associated with dial-up data transmission and as such they are rapidly becoming a more popular option with consumers looking for high-speed Internet access. ADSL is also less expensive than many other forms of broadband and makes a great choice for those looking for a reliable and affordable Internet connection.
