Digital Subscriber Line (DSL) 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
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
standardized data-sharing protocols and universal connectivity, are making it easier for people to perform illicit activities via the Web. Further, with broadband technologies such as Digital Subscriber Line and cable modems making there way into more and more homes, the bottleneck once provided by analog phone lines and modems is disappearing making it easier to share large multimedia files via the Internet. Illegally distributing copyrighted materials is harmful to the industries involved, preventing

anywhere in the world. Without knowing anything about switching, one would think that there phone would have to have a separate line to everyone other phone in the world. This would be quite a lot of lines into just one phone and know that this is an impossible scenario. This is why the switched network was developed. A switched network brings each subscriber line into a centralized switching system, where connections are made for each call. The earliest telephone switches were hand-operated
billion dollar merger of America Online and Time Warner is one of the largest deals in corporate history. The deal combines the world's largest Internet Service Provider with the world's largest media company. AOL has about twenty-six million subscribers and also runs instant messaging services and Netscape Netcenter. Time Warner's cable network reaches twenty percent of cable homes in the United States, and also has its own film and music studios, cable and TV broadcasting properties such as HBO
at the time of this writing—the transfer of graphical images can be frustratingly slow. This report examines two enhancements to existing residential communications infrastructure: Integrated Services Digital Network (ISDN), and cable television networks upgraded to pass bi-directional digital traffic (Cable Modems). It analyzes the potential of each enhancement to deliver Internet access to residential users. It validates the hypothesis that upgraded cable networks can deliver residential Internet
The Combining of Cable TV and the Internet The Telecommunications Act of 1996 opened the way for cable TV (CATV) companies to become full-fledged telecommunications companies, offering two-way voice and data communications services, in addition to television programming. After passage of the Act, the cable companies were eager to expand into the new fields of business that had been opened to them, especially the rapidly growing Internet Service Provider (ISP) business. The biggest hurdle facing
consumers companies must keep up with the latest consumer trends while keeping costs low in order to grow their market share. In contrast to the largely stationary internet of the early 2000s, Americans today are increasingly connected to the world of digital information while “on the go” via smart phones and other mobile devices. In fact, according to pewinternet.org 95% of Americans now own a cell phone of some kind. The share of Americans that own smart phones is now 77%, up from 35% in 2011. As consumers
at the end of the 2003 there were more than 1billion individual subscribers, that means under one in six people had subscribed to a mobile service . By the end of the 2013 the number of mobile phone subscribers has doubled, there were 6.8 billion mobile cellular subscriptions in 2013 it is nearly world population 7.1 billion. Furthermore (GSMA, 2014) report mentioned that in 2020 there will be 9.2 billion mobile cellular subscribers in the world. With the fast growth and the rapid development of
Direct-to-Home (DTH) service, Airtel digital TV. The company provides end-to-end data and enterprise services to the corporate customers through its nationwide fibre optic backbone, last mile connectivity in fixed-line and mobile circles, VSATs, ISP and international bandwidth access through the gateways and landing station Globally, Bharti Airtel is the 3rd largest in-country mobile operator by subscriber base, behind China Mobile and China Unicom and with 139 million subscribers it is the largest mobile operator
Digital communication is the electronic exchange of information through various media. I am growing up in a quickly advancing digital world where technology has had major effects on society. Anyone who has grown up in the 21st century has always had technology in their life whether through cell phones, television, computers or game systems. The use of social media outlets to communicate with others has been a highlight among the 21st generation and is a major method of communication in today’s society
you would pick up the receiver and be connected to an operator at the Central Office (CO). The CO is the local telephone office which all local lines connect too and where circuit switching of subscriber lines occurs. The operator would determine which two lines need to be connected for the parties to talk and connect the lines. To connect the two lines the operator would plug a cord connecting the two ports on a cord board to bridge the two ports together. The cord board used by the operator to

The use of digital devices in everyday life is increasing as people integrate technology into their lives. It is estimated that as of 2010, the number of mobile phone subscribers has increased from 5 billion people around the world. In addition, new consumer devices, including tablet PCs and devices, will continue to be introduced Wi-Fi playback and media playback devices, as well as cars and devices capable of connecting to the Internet. The proliferation of electronic devices in the community
they have a new market they need to gain a presence in exists and is not faddish or temporary. Over 600,000 subscribers have transitioned to Sling TV and are seeing accelerated subscriber growth as more people trade in their cable boxes for streaming media. According to the A Levy article over 800,000 people left their cable providers last quarter, and the paradigm shift is directly in line with the Porter’s 5 Forces analysis tool by showing the existence of threats of the new market entrants, (Hulu

transmission is a technique used in serial RS232 communication. The data is framed by a series of control bits known as the start bit, stop bit(s), parity bits and error checking bits. A transmit clock signal is used to clock the data over the transmission line to the receiving end. At the receiver, a clock signal, known as the receive clock, which corresponds to the transmit clock is used to decode the transmitted data back to the original by stripping off the control bits. Synchronous transmission sends
independently of other processes, whereas synchronous operation means that the process runs only as a result of some other process being completed or handing off operation. Analog and Digital: Analog communication employs continuous transmission of an electromagnetic wave form that varies in frequency and amplitude. A digital communication system uses discontinuous transmission that may vary in frequency, amplitude and/or phase to represent binary data. Simplex and Duplex: A communications network can
