A local loop is the wired connection from the telephone company’s central office in a local area to its customer’s telephones. It was originally constructed for voice transmission only using analog transmission on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network or Digital Subscriber Line, the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only.
The central office is an office in a local area which subscribers home and business lines are connected; it has equipment that can switch calls locally or to long distance carriers.
Local exchanges, a telephone exchange, are a telecommunications system used in the public switch telephone network. An exchange consists of electrical units, in older systems human operators, which combine telephone subscriber lines or virtual circuits of digital systems to provide telephone calls between subscribers. A telephone exchange is located in a central office, a building used to house the inside plant equipment for possibly several telephone exchanges.
POP or point of presence is an access point to the internet; internet service providers generally have multiple POPS. A point of presence is a physical location, either part of the facilities of a telecommunications provider that the ISP rents or a separate location from the telecommunications provider that stores servers, routers, ATM switches and digital/analog call aggregators.
Fixed Lines, or also known as landline telephones, are phones that use a solid medium telephone line (metal wire of fiber optic cables) for transmissions; fixed phones can be hard wired or cordless. Cordless or fixed wireless refers to the operation of wireless devices or systems in fixed locations such as homes. Fixed wireless devices usually…...

...haha NT1310 unit1 assignment 3/18/2013 Part 1 Description: Please write 3-4 sentences for each of these services, describing whether they use voice or data networks: o Cell phones: Cell phones are both voice, and data. The first generation cell phone transmitted information in an analog format very similar to the way a fixed-line telephone transmits voice information from the subscriber to the central office. When the second generation cell phone entered the market transmission shifted from analog to digital. Not only do 2G phones have the ability to transmit and receive voice but they also have the ability to transmit and receive data. o Landline phones: Landline phones use both voice, and data networks. Originally it was just voice, then "the data network" began with dial-up modems, and fax machines. o SMS/ Text Messaging: Text Messaging is a data network. Cell phones pave the pathway for SMS messages. When a friend sends you an SMS message, the message flows through the SMSC, then to the tower, and the tower sends the message to your phone as a little packet of data on the control channel. Cell phone calls are different, they use radio frequencies instead. o Fax Machines: Fax machines are in a data network. Fax machines transmit mainly through landline phones. Recently, they also send through Voice Over Internet Protocol (VOIP.) o Pagers: Pagers are data signals that receive similar to cell phones, but with no voice radio frequencies. o......

...NT1310 Physical Networking Assignment 1: Voice vs. Data Cell Phones – Cellular phones are used for both voice and data communications. A person talking on a cellular phone uses voice communications and then gets sent back to the base station. Data technology is also used on smartphones which allow the user to browse the internet and download files. Landline Phones – Landline phones typically only use voice communications. Some newer landline phones can use what is called a NCID (Network Caller ID) which uses data sent over a TCP connection. SMS/Text Messaging – The SMS (Short Message Service) can be used in a variety of ways. Some examples include: cellular phones, GPRS systems, and web texting. SMS does not use any kind of voice technology and therefore is sent over data networks. Fax Machines – Fax machines contain analog modems. This type of modem technology uses the voice network technology. When the receiving end handles a fax connection it listens for a digital connection that has been converted from an analog signal using a voice network. Pagers – Pagers also known as beepers were primarily used over data networks by sending numerical short messages similar to the SMS service. Since the introduction of data pagers, voice pagers have also emerged. These types of pagers use a voice network to transmit a short audio message that the user can then retrieve. VOIP Phones – VOIP (Voice over Internet Protocol) is a technology that can transmit audio......

...NT1310, Physical Networking Activity 1 – Data on Fixed Line vs. Cellular Device Nick Conforti Mr. Hafet 09/15/2014 There are two main types of broadband connection, a fixed line or its mobile alternative. Both have their strengths and potential weaknesses so you need to consider what suits your needs before you sign up on a lengthy contract. Fixed line broadband is what most people have at home. It's a fast internet connection delivered by telephone wire (ADSL) or fiber optic cable. As the latter is now capable of speeds in excess of 100Mb, an increasing number of British homes have "superfast". Mobile broadband uses the same technology as mobile phones to give you internet access wherever you go with your laptop, netbook, tablet or iPad. It's slower and usually comes with a relatively low download limit, but allows you greater flexibility away from home. The Pros of having a mobile broadband is that you can take your broadband wherever you go - A mobile broadband connection is exactly that, which means that you can access your emails, check the sports results or watch YouTube videos no matter where you are, provided you have 3G receptions. Stop paying for line rental - Millions of people continue to pay for line rental on a home phone landline that they rarely use, just so that they can get broadband at home, with mobile broadband, there's no need to pay line rental - potentially saving you over $100 a year. The Cons of have a mobile broadband is Low......

...Nt1310 9/17/2014 Unit 1 Assignment 1 Cell phones – Cell phones use data networks to communicate over radio frequencies. The frequencies that they use are also shared with television, Bluetooth, and Wi-Fi. Landline phones – Landline phones use voice networks only because they do not need as much speed as anything else. Normal house phones use approximately 10 MB/s which is all that voice networks handle. SMS/Text messaging – Text messaging uses data networks because they can also be sending media like pictures and video. The other reason that I believe that text messaging uses data networking is because it is faster. Fax machines – Fax machines use voice because they only transmit exactly what is on the paper. It is not being transformed into little packets and sent over the internet to another place; it is just sent from one place to another through the phone line. Pagers – Pagers use the same as cell phones and that is data networks because it is wireless, and does not have to be plugged into anything. Pagers are not that common due to the cell phone industry growing swiftly. VOIP – VOIP as it says in the name of it uses a data network. It uses IP for talking so that the communication is more secure and not many people can tap in as easily as people can over regular phones. Skype/Facetime – Skype and facetime both use data networks to communicate because you are sharing video with somebody else. You are also receiving video, and video cannot be shared over a......

Landline phones uses the same as cell phones SMS/Text messaging uses data networks because it takes and saves an image of text and sends it over to the other end. Fax Machine uses data networks because a file is saved and sent over to the fax machine to be printed out. Pagers uses data networks because it is recorded and saved while being transfer over to the pager. VOIP (voice over IP) phones uses voice data networks. Skype/Facetime uses voice data networks because of live video streaming. Unit 1 Exercise 1, Local Exchange Any movements and sounds on one end is recorded and sent as data through demarc live-tie, to the access networks. Then from access network it would go through metro network (city to city) and regional networks (county to county). From there it travels to long haul (state to state). Then to ocean networks (country to country) if players are out of the country gamers. After all that transfers, it back tracks to the other end of the receiver who is playing the game. Unit 1 Lab 1.

...NT1310 Unit 1. Lab 1. Data on Fixed Line vs. Cellular Debate. Pros & Cons of Fixed vs. Cellular: Pros: Cost:  Most wired line phone companies charge more than what you'd pay for most alternatives, and some are taxed more as well. There are some locations where getting new wired phone service is prohibitively expensive or even impossible. Long Distance and extra features like Call Waiting are normally included with alternative phones. More Features:  Cellular and broadband phones normally include Long Distance, Voice Mail, Caller ID, Call Forwarding and more, usually at no additional charge. They also have Text Messaging and various forms of data service which are unavailable with a landline. Portability:  If you move your home more than average (or if it's on wheels), your phone and your number can stay with you. There are no "installation" charges. Temporary Usage:  You can have phone service for the season in a vacation home or cabin, or on an extended stay at a hotel or home of a friend or relative without installing a separate line. Internet Access: Your wireless phone can also be your connection to the Internet, either with an internal browser or tethered to your computer, and available wherever there is cellular coverage. Wireless broadband is also available separate from your cellular account. Wi-Fi for Multiple Devices: You can get a cellular modem that provides a wi-fi signal that can connect to up to 5 separate wi-fi devices. ...

Copper vs. Fiber Nt1310

...Copper vs. Fiber Todd Gerger NT1310 Abstract In this paper we will be looking at the differences between Copper and Fiber optic cables. We will discuss the differences between the two and why many of the current networks in operation use fiber on the backbone between equipment and telecommunications rooms or enclosures. Copper vs. Fiber In the comparison between fiber and copper fiber, costs of the fiber cable has come down quite a bit. The cable itself has become easier to install as well since the invention of the flexible fiber which makes it easier to pull the cable through places. The flexible fiber has not become widely used vs. copper yet due to the need for the costs to come down for the connections, the NIC’s. the hub’s, routers and switches. Fiber Advantages The following advantages of fiber over other cabling systems are: (Oliviero 250) Immunity to electromagnetic interference (EMI), higher data rates, longer maximum distances, and better security. With copper cabling there is one common cabling problem they are susceptible to EMI. EMI is a stray electromagnetism that interferes with the signal. All electrical cables generate a magnetic field around their central axis. If you pass a metal conductor through a magnetic field an electrical field is generated in that conductor. When you place two cables next to one another EMI will cause cross-talk which is where signals from one cable is picked up on the other cable. Because fiber does not conduct......

Forward Biased LED- When the LED is forward biased (a positive voltage is applied to the p region and a negative voltage to the n region), current flows through the LED. 2. Incoherent Light- Photons emitted from the junction where the p and n regions meet are not in phase, nor are they launched in the same direction. These are out of phase photons 3. Laser- Acronym for light amplification by stimulated emission of radiation. It produces a coherent source of light with a narrow beam and a narrow spectral bandwidth. Used to provide the high-powered, tightly controlled light wavelengths necessary for high-speed, long-distance optical fiber transmissions. 4. Output Pattern- The output pattern or NA of the light source directly relates to the energy coupled into the core of the optical fiber. The output pattern of a laser light source is very narrow, allowing a majority of the light energy to be coupled into the core of a single-mode or multimode optical fiber. 5.
