How Does DSL Work?

When choosing a method of connecting to the Internet, you may end up asking the Internet service provider, how does DSL work. DSL stands for the phrase Digital Subscriber Line.

DSL is a standard, high-speed connection that uses a telephone line in order to connect to the Internet. Even though DSL shares the telephone line to connect to the Internet, it is a spliced telephone line connection that enables you to still work online while having the capability of talking on the telephone.

Your DSL line, better known as an asymmetric digital subscriber line, divides the different frequencies which enable you to upload and download content at lightning speed. The DSL modem plays an integral part in this process as does the end-user’s telephone company.

The light speed connection that DSL has is usually organized according to its bandwidth rating. DSL bandwidth rating can range from 1.5 Mbps to 3 Mbps.  Believe it or not, the 1.5 Mbps is the maximum allowable bandwidth available for downloading capability. Three Mbps is the maximum allowable bandwidth for uploading data from the Internet.

What Is DSL?

Much different than a dial up connection, DSL connects through a modem that is a direct connection to your telephone line.

DSL has the capability of shifting digital data through your computer unchanged.  If it starts out as digital data it will go through your computer as digital data without changing to analog unless the signal is split to all both digital and analog data to filter through. This is what a DSL modem does – it splits the signal so that you can work online (digital signal) while talking on the telephone (analog signal).

Advantages of DSL

One of the advantages of DSL is that it is practical. You will not have to buy any new telephone lines or any other product that requires assembly. Once you order it, the telephone company will send a representative out and have them assemble everything for you.

Another advantage is that DSL offers computer owners a certain level of protection, not offered by other high-speed Internet companies or satellite cable companies. The protection lays in the comfort of not be left out as prey to identity theft or the destruction of the data. 

Because DSL operates off of your telephone line, you are offered the same identity protection as the phone company would normally offer you had you not have been a DSL customer. So there is comfort in knowing that you are protected in a sense, and not left out as prey.

DSL is also quite user-friendly, with easy operating instructions that make going online a pleasurable experience.

Disadvantages of DSL

While DSL has many advantages, there are a few disadvantages to the service as well. Unfortunately, since DSL works off of the telephone line and signal, the availability of the service is more often than not determined by how close or how far away a consumer is located from the DSL provider’s central office. So if you live in a rural area and the nearest central DSL office is in an urban epicenter 200 miles away, you may experience a bit of technical difficulty trying to maintain a signal for your DSL service.

Additionally, you may find that receiving certain data files operates quicker and smoother as opposed to sending data files. Another disadvantage of DSL is that each year users may find that they will need to get a new modem in order to maintain a connection. The reason for this is that there is no standardized DSL modem. 

Additionally, DSL is not compatible with a fiber optic line. Telephone lines are copper lines whereas a fiber-optic line offers a higher speed that surpasses the speed of DSL. When it comes to telecommunication, DSL is still a relatively good starting base for high speed telecommunications.

For the most part, DSL works very effectively. For more information, contact your local telephone company.
