You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week.

1. Describe a local land line phone system based on the following Landline Telephone Components:
a. Local Loop a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only.
b. Central Office
In telephone communication in the United States, a central office (CO) is an office in a locality to which subscriber home and business lines are connected on what is called a local loop. The central office has switching equipment that can switch calls locally or to long-distance carrier phone offices.

In other countries, the term public exchange is used.
c. Local Exchanges
A telephone exchange is a telecommunications system used in the public switched telephone network or in large enterprises. An exchange consists of electronic components and in older systems also…...

...Skill Building Exercise Week One: How LEGO Revived Its Brand “Three generations of kids have built cars, cities, and spaceships with Lego’s iconic bricks. Its logo—the red square with the rounded white letters—is immediately identified by most of the developed world and to a bunch of developing nations as well.” It is for this reason I was surprised to find an article written about Lego's comeback. The article states that the company’s problems began in the late 1990s, when Lego stopped focusing on design and started venturing off into new product development like Galidor, in which the company co-produced a kids’ TV show basically to spark interest in the product. The Galidor did not require building skills or much imagination, which is the hallmark of Lego products. The show and the product line sparked little interest. Lego was foundering. It was at this time that Lego gave designers free rein to come up with imaginative creations. And they took it and went overboard. By 2004, the number of components went from 7,000 to 12,400 and supply costs sharply increased. However, just as design pushed Lego to the precipice, it too helped bring the company back—but this time with parameters. Gradually the company started reshaping its product line from futuristic fire trucks to fire trucks that were recognizable to kids and by 2008, the City line reclaimed it spot at the top of Lego’s portfolio and with parameters in place scaled components back down to 7,000. Going......

...Week 1 Exercise 1. Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop The local loop is the physical wiring that connects you to the public switched telephone network (PSTN). This line can be a voice line, or it can be a data line. The physical wiring for the local loop consists of a pair of twisted copper wires that run from the telephone company's central office to the subscriber's premise and another pair of twisted copper wires that run back to the telephone company's Central Office1 b. Central Office A Central Office is part of the telephone network in your area. It is a building in which the phone lines in your home or office terminate and connect to a much larger switching system. In large metropolitan areas, Central Offices are more appropriately LOs (local offices), because they serve a local area. The term "Central Office" is from the early days of the telephone system when the local telephone company really did have only one central office in each area.1 c. Local Exchanges A telephone exchange is a telecommunications system used in the public switched telephone network or in large enterprises. An exchange consists of electronic components and in older systems also human operators that interconnect (switch) telephone subscriber lines or virtual circuits of digital systems to establish telephone calls between subscribers. Also referred to as the Central office. d. POP In the telephone system, the......

...Unit 1 Exercise 1 Local Exchange When you send an email from New York to Japan, that email,is sent from your home to the local exchange point over the access network. Once it is in the local exchange it is then sent to aggregating points in different cities and counties over the regional network. Then it is aggregated and transported over the long-haul network so that it reaches the launching point at the country shoreline where it is then sent over the ocean network to Japan. Once there, the email is sent back over the long-haul or regional network to the local exchange and then on to the individual receiving the email. This occurs using mostly fiber optics so the speeds at which all this takes is at the speed of light which is approximately 127,000 miler per second. understand how to interface with the local exchange you must first understand the different networks that comprise it. The first network, being the access network. The access network is the network that connects the individual user or business with the telecommunications system. This is made up of a series of fiber-optic and copper cabling and passive and active equipment that connects you to the local exchange. The central office at the local exchange contains the switching equipment to direct your telephone, data , video, etc. to where it needs to go. The access network is very important to the local exchange since it’s the part that reaches the end user, who is you, and connects them. The metro network,......

...1. A. A local loop is a loop of copper wire that allows a current to flow from a telephone to the central office and back. It is a dual-wire physical interface that connects a telephone to the central office and are typically referred to as a twisted pair. Many of these pairs are twisted together to make a cable for a local loop to provide multiple connections for multiple phone to interface with the local central office. b. A Central office is a building to which a subscribers home and business lines are connected to a local loop. This office has telecom. Switches to switch calls locally or to a long-distance carrier. A central office is also referred to as a local exchange. The subscribers associated to each central office in their local are identified by the first three digits of their telephone number, however, the last four digits identify the specific subscriber. One central office can support up to 10,000 subscribers with the same three digit prefix. Central offices can also support more than one local exchange. c. Local exchanges or local exchange carriers are telephone companies that provide service within a designated geographical area or an LATA, local access transport area. One LEC serves multiple central offices depending upon the geographical size and the population of the area. d.

...final place information goes before hitting the main core network. Cable TV has made some great advances as well. When it was first implemented, it operated over the radio waves. One of the biggest limits of this was range, as the weak signal found at longer ranges would garble the picture at the end point. The solution for this issue is the Community Antenna Television (CATV). This amplified the signal so the broadcast would go over further distances. Eventually, however, the signal was ran over copper coax and fiber-optic cabling directly to people’s houses. The cables would run to a Network Access Point (NAP), which is the terminal that serves as a connection point for the cabling into the houses or buildings it serves. A cable will then run from the NAP to the Network Interface Device (NID), which is mounted on the building itself. It is the carrier’s drop point to the customer’s house, as usually the customer is responsible for everything from the NID up to their equipment. The telecommunication companies now, for the most part, handle all of these functions. One of the biggest companies around was AT&T until 1982, when it was broken up by the US government. They were divided into 7 RBOCs, which handle all services by region. However, AT&T purchased 4 of these regions by 2006. One thing these RBOCs are required to do as of 1996 is lease parts of their networks to smaller companies, so they can provide access to customers while not owning the local loop. This......
