Everyone nowadays is accustomed with the term Internet and Internet service providers. Everyone knows how to use the Internet, but there are just a handful of us who actually try to go deep into the matter and try to find out how the process works. At the same time, many of us who are the consumers often don’t try to gauge the advantages or disadvantages of the process before investing in it. Take for example if you use DSL internet connection, as the consumer how much do you really know about it? Some DSL internet providers however choose to be transparent with their consumers and can easily provide the details for customer satisfaction.
They start off with a very basic understanding of DSL, which stands for Digital subscriber line. The mode of operation for this is simple. DSL internet connection is provided through regular telephone lines. It is a very high speed internet connection and is available to users without disrupting their monthly budget.
Start counting the advantages of a DSL internet connection. The very first point which attracts attention is the fact that the user can leave the Internet connection open while at the same time uses the phone line for making voice calls. The speed is the second highlight which is guaranteed to be higher than any regular modem.
A DSL connection is money saving from the very initial point. This is to say as it uses the existing telephone lines for the transmission and does not require any major installation; there are no overhead charges that are to be included within the package. The user does not require to arrange for any modem. The DSL internet provider will take care of it as it is the responsibility of the company from where you are taking the connection to provide the modem as well.
Once the advantages are known, the next step is to have a little understanding of how the transmission takes place. It is unique to see how DSL connection squeezes information through regular telephone lines even when it is in use. It is simple. DSL uses copper lines which have the strength to handle more bandwidth or range of frequencies that is required for voice calls. What DSL internet providers do is to take advantage of the excess bandwidth without hampering the abilities to make voice calls.
Dive a little in the details to clear up the picture more. For this a slight knowledge of the regular telephone line will help. The telephone company makes the best of their equipment by limiting the carrying capacity of the switches and telephones. Normally, the maximum frequency range that is utilized ranges between 0 –3400 Hertz for normal conversations and a maximum of 20 – 20000 Hertz for stereo speakers. There is a lot more capacity in the telephone wires to handle frequencies more than this. The limiting of the frequencies helps. By doing this, the telephone can accommodate large number of wires into a small space. The chances of interference are nil. DSL follows what most of the modern equipment does nowadays; that is sending digital data rather than analog data using much of the telephone lines capacity.
However, there are certain disadvantages of DSL connection as well. For example, the distance from the provider’s central office and your location is crucial. The more the distance, chances are bigger of the signal getting weak. DSL internet connection is good for data reception but not data transmission over the internet. The last minus point happens to be the absence of a large number of DSL internet providers. Since the providers are few; consumers have a limited number of choices in hand.
