AT&T 5ESS Switch is The Best in Telecommunication The direction of this paper is to describe a telecommunications switch and show its purpose and multitasking abilities. This paper will use the AT&T 5ESS Switch to give a real world example of a top rated telecommunications switch. The end result will be an understanding of how a switch works and what it can do. Also, it will show why the AT&T 5ESS Switch is #1 in today's telecommunication world. SWITCHING In today's world a person should be able to pick up his phone and dial to almost 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 - that is, they required a human operator to make connections by plugging circuits into a switchboard. When the customer "rang" the central office, the operator scanned the switchboard and connected the caller by plugging into the requested line. The invention of the mechanical switch came about in the late 1880. Now, the mechanical switch replaced the human operator, who handled the physical connections. These early switching systems were based on the analog technology that was state-of-the-art electronics at the time. By the mid 1970's digital technologies were being introduced into the core of the public switched network. Digital switches fully capitalized on the strength of the... ... middle of paper ... ...p://www.lucent.com/netsys/5ESS. Unknown. "5ESS Switch."

Have you ever wondered how your phone company started out? Or the new innovations it has brought about? And maybe even how the business is run? Well, today I’m going to talk about AT&T’s history, the products it sells, the employee jobs and U-verse.
The telephone was said to be invented by Alexander Graham Bell, some critics believe that the real inventor was a man named Elisha Gray. After many debates people commonly now believe that Alexander Graham Bell invented the first telephone. Inspired by his deaf parents he wanted to invent something that people could use easily and was easy to access. So he worked on his invention day and night for many days. Eventually He got the perfect thing that he had been looking for. He had finally invented a device that you could hear human voices through technology. On March 7, 1876 after all of Alexander G. Bell’s hard work he patented his great invention...
Knob and tube wiring was state-of-the-art up until around 1950. The main concerns with this old wiring method is overheating, deteriorating insulation, improper connections, and that it is not a grounded system. K&T wiring was ideal for when it was originally designed to hold modest currents. But nowadays the electrical demands for the average house are considerably greater. Sixty years ago t...
Phones have come a long way from their beginnings. When the first phone was developed, a mere phone call took up to ten minutes just to connect. The calls made on this phone would go through a system of connections where the caller would have to state who they were calling and where the person lived. It would be many years later that a telephone would be created that made use of a dial, which made calling easier. In 1963, the first pushbutton telephone was distributed by the company, Bell Telephone. In 1983, the first cellular device, the Motorola DynaTAC 8000X, was created, which took the world by storm. Soon later, miniature computers were being put in these devices, allowing the user to browse parts of the web while on their cellular device. Yet we wouldn’t see a product that allowed us to browse the web, communicate with others, and let us store music and run apps, until 2007. (ht...
According to the modern way of life the need for computer in every work place and home is high which decreases even more the power of the customers. However, the switching costs are low (2.2)
Cell phone technology dates all the way back to 1947. “In that year researchers first developed ideas as to the possibility of creating mobile phones that used "cells" that would identify a user in whatever specific region he or she was initiating the call from” (Cell Phone World). Still the technology was very limited at the time, so much more extensive research was required. In 1968 private companies started getting involved with cell phone development, such as AT&T. The FCC (The Federal Communications Commission) then opened new frequencies and the private companies had the theory of cellular towers. Each tower would be responsible for a particular region. When a customer traveled farther a way from one region it would switch the call to a closer tower with no interruption. In 1977 public cell phone testing had begun. People in Baltimore, Chicago, and Washington were the first to be eligible for cell phone trials. In 1979 a company in Japan began doing cell phone testing with the public. Not until 1983 were cell phones really available. “The year 1988 changed many of the technologies that had become standard in the past. The Cellular Technology Industry Association was created to set realistic goals for cellular phone providers and research new applications for cell phone development” (Cell Phone World). In a way they still were not very accessible to the public, due to their extremely high operating cost to the consumer. Only the very wealthy could afford cell phones. Important heads of cooperation’s, movie stars, and top government officials were able to afford the luxury of a mobile phone.
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).
In addressing the problem, the proposed research will use the case study method to examine the plan, design, and implementation of WLAN technologies at Berean. At present, the non-wireless local area network (LAN) technologies employed by Berean include 10/100BaseT Ethernet at each desktop. Ethernet ports at the desktop are switch connected to an Asynchronous Transfer Mode (ATM) T1 backbone. Berean¡¦s one remote facility connects to the network using switched Frame Relay services along with Internet Virtual Private Network (VPN) connections.
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.
Following this, undersea cable and satellites, which made it possible to link points halfway around the earth sounding as if from next door. Finally, by adding three digit area codes, all phone calls, either to next door or around the world, can be made by the caller. The first telephone company to establish a telephone industry was the Bell Telephone Company, in 1877, by Alexander Graham Bell. This did last for sometime, however, independent telephone companies were started in many cities and small towns. By 1908, many customers were being served by a new company called AT&T, which eventually bought out the Bell Company.
On June 21, 1890, Bell and his assistant Charles Sumner invented a wireless telephone, named a photo phone. This photo phone allowed the transmission of both sound and huma...
Telephone lines and radio signals allowed individuals to communicate across the world. Alexander Gram Bell was the first to invent the telephone. While coming to the US to become a teacher for the death he thought of the idea of “electronic speech”. “This led him to invent the microphone and later the "electrical speech machine" his name for the first telephone,” stated www.pbs.org. Many contributed to the invention to the electric phone with the idea of the acoustic string phone, known as the lover’s phone. The tin can telephone had two tin cans tied together to with a string and wire. People today make this as a joke to talk to one another and kids also make the tin can phones as a toy. This illustrates that social media has always been around and even though it is a joke to today’s society this is how people used to have social interactions with one another before the Internet took
switching behaviour. Literature reveals about the factors of switching cost, better customer care services, networking coverage, advertising , etc for switching behaviour of customers. The researchers identify the problem of industry that if one firm gains then other must be losing a customer. Number of network providers are increasing calling for an intense competition. Empowerment of technology has led to growth of mobile industry more economical.
When phones became available to the public they were not considered to be mobile in today’s sense of the word. They were available to have installed in an automobile, they were big and bulky, and they needed and consumed a lot of power to use. The phone networks would only support a few simultaneous conversations. Cell phones since then have made vast improvements in their efficiency, abilities, and size. The first handheld mobile phone wasn’t produce until 1973. The origin...
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.
