1. An introduction
Digital subscriber line (DSL) technology transforms an ordinary telephone line into a broadband communications link, much like adding express lanes to an existing highway. DSL increases data transmission rates by a factor of twenty or more by sending signals in previously unused high frequencies. DSL technology has added a new twist to the utility of twisted-pair telephone lines.
DSL is a family of technologies that provide Internet access by transmitting digital data over the wires of a local telephone network. In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology. DSL service is delivered simultaneously with wired telephone service on the same telephone line. This is possible because DSL uses higher frequency bands for data. On the customer premises, a DSL filter on each non-DSL outlet blocks any high frequency interference, to enable simultaneous use of the voice and DSL services.
2. The technology’s application: where, how it works and who is using it.
Where, Who is using it This Digital subscriber line DSL
DSL technology is suitable for households and small businesses, particularly in rural areas, who may have access to other types of Internet services like cable Internet, DSL is also the very appropriate to the customers who want to use the internet with a package quite economical. While DSL is slower than cable Internet, it forms the lack of speed with a much more economical than cable Internet. DSL service providers rarely have any data, so DSL is ideal for those who spend a lot of time online every day, like small businesses or home. In addition, with technology DSL this can attra...

...at can be made to the DSL technology is, it's one of the service enables users to communicate internet and phone line simultaneously without any interference between the line internet and line, etc.In addition, the rate of speed for DSL is much higher than a care with modem. Besides that, the price for this package for DSL is much cheaper than others and it's very affordable to customers who want to surf the internet with cheap and easy. However, there are still shortcomings and benefits of this harness DSL and there are still line the internet far better and faster than DSL service such as Unifi, WiMAX etc.

As we can see and experience technology is overcoming everything we do in our lives. Technology is literally everywhere and anywhere. In the past few years technology has been developing gradually which is a really good thing. Technology provides the facilities which make our day today life easier. For Example few years ago, there weren’t that many cable facilities so it was expensive to take the advantage of the facilities. However nowadays companies like RCN, AT&T, Dish Network provides cheaper and easier access to receive entertainment and news from all over the world. Out of this entire corporation, I like the Comcast. In this essay I will talk about a nationwide largest corporation in the US. Comcast Corporation is the largest cable operator,
The telecommunications industry is of vital importance to the development of the information-based economy. AT&T need to supply access to cost efficient, timely and innovative telecommunications services.
Telecommunications gained mainstream attention in the early 90’s; however the initial key market was business men and women, who used their phones whilst being on the move and so allowing them to communicate with their companies with ease. Though in the modern era, telecommunication went through segmentation in the market trends, and now in this day and age it would be difficult to find someone who does not own some form of mobile technology. Many phone providers battle to provide the best service for their customers (Figure 1).
Berean¡¦s existing network infrastructure is wire line, and uses a T1. Remote users access the network through a dial-up modem pool. Berean¡¦s wire line network model severely limits the accessibility and effectiveness of the Berean network. For example, employees in Berean facilities are unable to access the network easily from meetings, the cafeteria, or anywhere other than their offices. In addition, the effectiveness of remote users is limited by the slow speed of present-day dial-up modem connections.
As a small nonprofit social IT company established in 2001, Digital Divide Data (DDD) has various human resources (HR) challenges. One of such human resources challenges includes lack of financial resources which has prevented the company from attracting unskilled labor. The second human resources challenge facing the Digital Divide Data is the inability to retain its internally-trained managers and high-performing operators. This difficulty comes as a result of the insufficient finance to maintain the internally-trained managers who are highly sought for in both Cambodia and Laos. So overall, the current human resources challenge facing DDD is the difficulty in attracting unskilled
The uses of Digital Signal Processing in communications has become so large scale that nearly any form of analog communication is considered obsolete. Today, nearly any form of communication used, aside from verbal communication, relates to Digital Signal Processing. Some of the more prominent uses for DSP in communications are; local area networks, cell pho...
The changes in the technological can influence many part of societies. When the AT&T Company introduce their new product and services which is wireless and wire line technology will effects occur primarily through the new products, processes, and materials. Thus, changes in technological also often can achieve higher market share and earn higher return because, newly emerging technology from AT&T could derive competitive advantages. For example, internet today becoming more remarkable capability to provide information easily, quickly, effectively, and also can create more value for customer in the future and to anticipate future trends.
Fiber optic technology has opened the door to many more communication opportunities for the world today. It provides higher fidelity long distance telephone conversations, as well as secure communication systems. Today, more than 90% of the United States long-distance traffic is already carried over optical fiber; more than 15 million miles have been installed, virtually all of it using the original design.
Digital Subscriber Line new technology that takes advantage of standard copper telephone line to provide secure, reliable, high-speed Internet access. DSL refers to the family of digital subscriber line technologies, such as ADSL, HDSL, and RADSL. Connection speed for DSL ranges from 1.44 Mbps to 512 Kbps downstream and around 128 Kbps upstream. Unlike traditional connections DSL such as analog modems and IDSN, DSL deliver continuous “always on” access. That means multimedia-rich websites, e-mail, and other online applications are available anytime. DSL makes it possible for you to remain online even while you’re talking on the telephone-without jeopardizing the quality of either connection. DSL is available in a spectrum of speeds. Some are best home use, while others are designed to accommodate rigorous business demands. Whether for business or the home, DSL, offers unsurpassed price/performance value compared to other online options. There are the five facts that one should know about DSL. It is remarkably fast. With DSL service, you can benefit from Internet speeds that are up to 12 minutes faster than a typical ISDN connection and 50 times faster than traditional 28.8 Kbps modems. This means that in the 12 seconds it takes to read this information, you could have downloaded a 2 megabyte presentation file or web photograph. It would take 10 more minutes (600 more seconds!) to download the same with a traditional 28.8 Kbps. It’s highly reliable. One can depend on DSL because its proven technology takes full advantage of the existing telecommunications infrastructure. It’s inherently secure. DSL network provides a dedicated Internet connection via private telephone wires, you can bypass dial-up intruders or shared network hackers. Unlike traditional dial-upp modems or cable modems. DSL protects your valuable data with the most secure connection available. It’s surprising affordable. DSL is widely recognized as the most cost-effective connectivity solution for small buisness. DSL delivers industrial- strength like speed to multiple users at only 25% of typical TI costs. There is no better price option available. DSL is also an exceptional value for home users. At about $2 a day for services that meets the needs of most people. The connection is always on. It’s ready to run every minute of the day. There’s no more logging on and off. No more busy signals or disconnects. This gives you the freedom to focus on what you want to accomplish on line rather than focusing on trying to get connected.
Exploring The Internet The Internet is like a network of networks where any computer can link up to information stored within it. It is accessed by a telecommunications line and a modulator-demodulator (MODEM). It is brought to your computer screen by converting analogue telephone signals into digital computer signals. There are many advantages and disadvantages on the Internet.
Since its inception, the telephone has become one of the most important inventions of all time. Although some were skeptical about its replacement over telegrams, in the end the advent of this fine communication equipment has won the hearts of many. As a matter of fact, the telephone system had come to numerous facelifts that it literally connected the world before the internet was born. Because of its importance, homes and businesses can not live without it. In the U.S. alone, most if not all have a phone in the house.
Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in the past. A disadvantage is the potential for dramatic and widespread failures; for as has happened.
People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
