One of the more common questions that is asked in the field is that of DSL. “What is the difference between DSL, IDSL, HDSL, SDSL, ADSL, CDSL, CiDSL, etc?” First off, DSL is DSL. All of these forms of DSL are exactly that, different forms of DSL. DSL is and acronym for Digital Subscriber Line. This is a form of high speed internet that runs over existing or new telephone lines. As you see there are many different forms of DSL, and basically the difference is how the data is carried over these lines to the recipient and what type of lines they are.
As mentioned above, these different types of DSL are describing the type of line the signal is carried on as well as how it is carried. All of these are important, but more so for your service provider than you as a consumer. The one form of DSL that I want to cover, and that I feel is important for a consumer to know is DDSL. DDSL is an acronym for Dedicated Digital Subscriber Line. What this means is that this form of DSL is dedicated specifically for the subscriber’s use. There will be no other traffic “clogging” up your bandwidth and causing interruptions in service.
I always use the analogy of rush hour traffic. It will take you longer to reach your destination if you are using the same freeway that everyone else driving home is using. The freeway gets congested because there is an overload of people using it, and your normal commute of 20 minutes now takes an hour. The same thing happens with your internet traffic. If you were to have your own personal road directly to your point of destination that no one else could have access to, it would take less time for you to reach your destination. This also reflects the same principles of the internet, and this is how a DDSL works.
Instead of sharing your bandwidth with thousands of other people that can potentially slow down your internet speed and interrupt your service, DDSLs leave your line dedicated for your personal use. This will ensure that you will have sufficient speed to carry out the operations that you need your internet service for.
