o Cell Phones—Data overtakes voice when it comes to cell phones but can use both. People see voice as intrusive and as a waste of time, saving it for a last resort. According to the CTIA, the number text message sent last year was up 50% on the year before. Add to that email, the multitasking nature of SMS and instant-messaging, and the other non-voice-based communications available on our phones today. o Landline phones—Landline phones use both according to a few articles. Not much information given. o SMS / Text Messaging—Also goes with data usage with cell phones. Since SMS used signaling channel as opposed to dedicated channels, these messages can be sent/received simultaneously with the voice/data/fax network over a GSM network. SMS supports national and international roaming. This means that you can send short messages to any other GSM mobile user around the world. With the PCS networks based on all the three technologies, GSM, CDMA and TDMA supporting SMS, SMS is more or less a universal mobile data service. o Fax Machines—Voice they quite often share a phone extension and have fax switch. Although the two are becoming one and the same thing to a certain extent now. Internally all the large telephone companies are switching to unified data networks to carry all of their traffic, and tweaking the parameters for best results with each distinct type of traffic going onto the network. o Pagers—Typically familiar with a cell phone in different ways also using both voice and data. A pager, also known as a beeper is a simple personal telecommunications device for sending and receiving short messages. o VOIP (Voice over IP) phones— (Both) With VoIP, analog voice calls are converted into packets of data. The packets travel like any other type of data, such as e-mail, over the public Internet and/or any private Internet Protocol (IP) network. Using a VoIP…...

Cabling Assignment 1

...1. In your new position as a product specification specialist, it is your responsibility to review the end users’ requirements and specify products that will support them. Since you must ensure that the product is specified per recognized U.S. industry standards, you will be careful to identify that the customer request references the appropriate application and cabling standards. What industry standards body and standards series numbers do you need to reference for Ethernet applications and cabling? The IEEE maintains the industry standards for Ethernet protocols (or applications). This is part of the 802.3 series of standards and includes applications such as 1000Base-T, 1000Base-SX, 10GBase-T, and 10GBase-SR. 2. An end user is interested in ensuring that the network cabling they install today for their 1000Base-T network will be able to support future speeds such as 10Gbps to a maximum of 100 meters. They have heard that Category 6 is their best option. Being well versed in the ANSI/TIA-568-C standard, you have a different opinion. What are the different types of Category 6 cable and what should be recommended for this network? There is the Cat 6 and Cat 6A and Category 6A would be recommended for the network since it was intended for 10Gbps networking. 3. Your customer is installing communications cabling in a factory full of stray EMI. UTP is not an option and a shielded cable is necessary. The customer wants to ensure capability to operate at 10GBase-T. What......

Unit 5 Assignment 1 Cabling Factors and Tolls Discussion

...Unit 5 Assignment 1 Cabling Factors and Tolls Discussion Flexibility What type of install is the cable going into? Is everything in a fixed position? If you have an install where items are moved around without being disconnected, using highly flexible cable is necessary. Cables in these scenarios need to be flexible to meet those demands of mobility, and also for the life of the wire so that it does not crack, break, fray or short. We had a job at a university where we moved flat panels on a track system to create different screen sizes, and for that we had to make sure the cable would meet the demand. Capacitance Cat 6 is not always better than Cat 5. If a video extender is made for Cat 5e, using Cat 6 may cause you a problem. The electrical properties are different, and the circuitry inside may not be able to reconcile the increased capacitance. You should confirm with the manufacturer before making a substitute in a Category cable. Jacket What type of jacket does your cable need? You have plenum, riser, PVC/non-plenum and direct burial. Plenum cable is often required in commercial work, especially in buildings where there are open-air returns; it is essential to meeting code. Integrators will often use riser grade at the riser, and then transfer to plenum in the plenum space. This saves some cost, but I recommend you second-guess saving that few cents per foot in most cases. The chances of mixing up a box of cable and pulling riser in the plenum space may......

Unit 5 Cabling Factors

...4/14/2014 Unit 5. Assignment 1: Cabling Factors and Tools Discussion Three factors that need to be considered is being fire protected, water proof, and shock protection. Being fire protected, just in case a fire occurs, the wiring would be protected by a casing around the actual wires which in cause wouldn’t melt the casing and destroy the wires. Since the data room is usually in the basement of companies, if a flood occurs, there are wires that are protected by a casing that would not let water intrude into the casing. For shock protection, there is always a chance for a shortage to happen. Wiring and a lot of electricity used. For example, if there is a storm going on and lightning hits a generator and shorts everything out, it would not fry the wiring if they are protected from the shock. The two most important considerations to take into account when either pre-wiring a house or wiring after the house is complete, are the routing of the cable and the quality of the wire used. These two points are often overlooked and the decision to wire the house at all often comes as an afterthought, when most if not all of the interior of the structure has been completed. Some tools that would be useful to use are cable cutters, hole cutting tools, wire strippers, punch down tools, RJ45 connector crimp kits, pliers and cutters, label makers and electrical tape. The makeshift tool that we would use is a staple gun....

...Eric Satchell NT1330 Service Provider Types Unit 2 Assignment 1 July 3, 2014 Comparing Service Providers There are a lot of companies providing services, but AT&T provided telephone communication to the public. AT&T monopolized the telecommunication industry until the United States took them to court for antitrust and won. AT&T was broken up into eleven smaller companies, call Baby Bells. One of the companies that derived from this law suit was the Regional Bell Operating Company or RBOC. RBOC was a term that described one of the US telephone companies that provided telephone, telegraph, and long distance to the consumers. RBOC is part of a local exchange carrier allowed to compete for business. RBOC services internet service which in turn dealt with digital data. The merging companies provided different types of service based on the Telecommunication Act of 1996. ILEC or incumbent local exchange carrier is a telephone company that provided local telephone communications before the ruling to break up the Ma Bell Company. The FCC ruled that the ILECs must provide other telecommunications service providers access to their equipment to be able to provide a better rate to the consumer. This......

...Unit 1 Strategy Unit 1 Strategy Bailey Nelson MT460 Bailey Nelson MT460 A business strategy means the company is set out to achieve its desired objectives. It can simply be described as a long-term business planning. Typically a business strategy will cover a period of about 3-5 years but can sometimes even be longer. Strategic management is a three-tier process involving corporate, business, and functional-level planners, and support personnel. At each progressively lower level, strategic activities were shown to be more specific, narrow, short term, and action oriented, with lower risks but fewer opportunities for dramatic impact. Having a business strategy is very important for a business to run smoothly. As a company, management needs to know what direction they want to go in and then have a plan on how they are going to get there. ( Long-term objectives are “the results that an organization seeks over a multiyear period. Such objectives typically involve some or all of the following areas: profitability, return on investment, competitive position, technological leadership, productivity, employee relations, public responsibility, and employee development.” This is very important for a business to have so that they know what direction they need to go in when making decisions.

...Gevarish Carter Physical Networking Unit 1 Exercise 1 Local Exchange 9/28/15 The Local Exchange acts as the convergence point for the information sent to the consumers and the point at which services from the global telecommunication are distributed to the consumers. The central office at the local exchange contains the switching equipment to direct your telephone, data, video, etc. to where it needs to go. To understand that you must understand how to interface with the local exchange meaning you must know the different networks that compromise it. The first network is the access network which is the network that connects the individual user or business with the telecommunications system. It’s a critical part of the network because it’s the part of the network that reaches the end user and “connects them”. 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 second network is the metro network, sometimes called the MAN it is where the information is collected from the local exchange of the service provider as well as other service provider and then sent to the regional and long-hauled network. This is usually the last point before the information is sent to the core network. The purpose of a Network is to share data. To make this possible, you have to be able to connect to other computers. Companies that succeeded at doing this have a great profit with exponential growth......
