Have you ever heard of a modem called an ADSL modem? This modem is indeed a special concern in its era because it has various advantages and also a relatively simple way of working so it is very suitable for a computer network.

ADSL explanation
Asymmetric Digital Subscriber Line or commonly abbreviated as ADSL is a technology that will offer connection speeds that are faster than those offered by the traditional Internet via dial-up telephone lines. ADSL is the technology that powers many Internet connections around the world. Although new fiber technology allows for faster connections to the Internet, ADSL is still a popular choice because of its flexibility.
While fiber can now be connected to more blocks or multi-dwelling homes, ADSL allows individual customers to decide for themselves because the technology uses existing metal cables into homes or businesses.
History of ADSL
When looking back at the history of the internet, it’s hard to understand why it became popular before ADSL was launched with modems and routers giving it a whole new range of opportunities and speed. Suddenly little plastic twinkling boxes were in every home and office. But what about the future of ADSL?
ADSL was originally patented in 1988. Due to the high cost of deployment, it was years before the technology became successful. To achieve the kind of speeds that would make ADSL a viable alternative to dial-up internet, intelligent signal processing is required, which in turn requires specialized equipment.
Advantages of Using ADSL
If asked what is the future of ADSL? Is this really a technology that can still be patented even though there are already many networks that use fiber optics?
Let’s look at the advantages of ADSL. ADSL has many advantages including:
-
High Speed Access
In fact, ADSL does use higher frequencies than landline telephone lines. The majority of broadband connections today use ADSL techniques, but they are increasingly competing with fiber optics. Modern ADSL solutions can provide much faster speeds compared to traditional modems.
-
Reasonable Flat-rate Rates
ADSL does not use a home telephone network. So, this automatically makes ADSL guaranteed to be cheaper and more able to provide a very reasonable flat-rate price. So, of course, in this way you can stream various kinds of movies and also play games to your heart’s content.
-
Always On Connection
The advantage of ADSL is that the connection can always be active without a dial-up process. An Asymmetric Digital Subscriber Line connection can provide more benefits because you can surf the internet in real time.
Disadvantages of ADSL
If you ask what are the drawbacks of ADSL, what you can really tell is that the service is not available everywhere, It works better when it is closer to the ISP’s central office, It offers variable speed depending on the time of day, It provides faster downloads than upload, Testing path takes long time.
Distance Can Affect Data Transmission Speed
The first thing that is highly recognized as a drawback of ADSL is the problem of distance. When the distance from the telephone exchange is farther, the signal strength is weaker, Connection is slower at peak times.
There are Load Coils
The second is the presence of load coils and bridged taps. LEC or Local Exchange Carriers use load coils to add telephone facilities in areas that require additional equipment or copper loop installation. The load coil is an induction device that shifts the tone carrier frequency upwards. This is compensation for the capacitance of the cable especially for ranges in excess of 18,000 feet.
Unfortunately, the tone frequency is shifted to the frequency normally used for DSL to create interference that is intolerable. So this method makes the line unsuitable for ADSL.
ADSL function
Even though this technology is indeed considered old technology, this technology is still very useful for small businesses that have low dependence on technology. Perhaps only one call needs to be made at a time and business owners are often online after off-peak hours.
How to use ADSL
For ADSL in Indonesia, you need to check the devices that have ADSL available. Then what needs to be done is the existence of a telephone number that is available at Telkom Indonesia. Contacting Telkom Indonesia is to determine the distance between the Telkom substation and your house. Why is it needed? Because what was said earlier, is how ADSL greatly affects the speed to the distance.
To be able to connect ADSL with telephone lines, you can use a device called a line splitter or splitter. This splitter function is to eliminate interference when using the internet and communicating via telephone simultaneously.
Is ADSL Still Keeping Up with the Times?
When the internet had its breakthrough among the masses somewhere in the mid 90’s, households could connect to the web with so-called modems. This modem blocks the entire capacity of the phone line and disables phone calls while surfing. Moreover, traffic never attained great speeds even if some developments occurred in this technique.
What came to replace the so-called modems was the ADSL technique. However ADSL uses the telephone line for traffic, but does so at a high frequency so there is plenty of capacity left for telephone calls. ADSL modems can provide much higher speeds than their predecessors.
So, can the ADSL modem keep up with the times? Of course the answer is definitely able to keep up with the times.
