Answer the following “Test Your Understanding” questions using APA style and form:

a. Below what speed are there different leased line standards in different parts of the world?
Difficulties start below 50 Mbits of data so different countries have different lease line standards. b. What is the exact speed of a T1 line?
A T1 line is a lease line in North America. This connection is a dedicated connection that can support up to 1.544 Mbps based on a digital signal on 24 channels at 64 Kbps. c. What are the speeds of comparable leased lines in Europe?
The comparable lease lines in Europe to a T1 in North America can support up to 2.048 Mbps. The network structure is similar yet still different from the network setup of North America. d. Why are fractional T1 and E1 speeds desirable?
Fractional T1 and E1 speeds have a large effect on costs, efficiency and use. The use of these dedicated lines is dependable and consistent and mainly used by companies and/or individuals who require a dependable access to the internet. e. List common fractional T1 speeds.
Fractional T1 speeds include 128 kbps, 256 kbps, 384 kbps, 512 kbps, 768 kbps. f. What are the most widely used leased lines?

...Telecommunication Systems This paper will describe in general terms the telecommunication system currently in use at a private optometry clinic. The facility is owner operated with six employees and one location that provides a number of services to the public and area optometrist. This includes partnering with an optometry therapist to provide a full array of eye care services for pre and post eye surgery patients. Also included in this paper are short definitions of Rotary and Dual Tone Multifrequency (DTMF), Wide Area Telecommunications Service (WATS), Private Branch eXchange (PBX), and The layers of the International Organization for Standardization-Open Systems Interconnection (ISO-OSI), telecommunication terms as the relate to this business. Gaining permission to view and evaluate the telecommunication systems of a small family owned and operated business when you have been working there less than a week can be a tricky matter. I began by explaining that my interest in the system is purely school related. I continued by letting him know that the conversation and information exchanged could assist in developing a more effective system for the business. This helped but, skepticism and caution were still the overriding view of Doctor Martin business owner and board certified ophthalmologist. Ensuring the privacy of his business records appeared to relax him a bit as did telling him that I did not want any defined information just general. Telling him that I......

Networking Concepts and Applications

...Networking Concepts and Applications Week 1 Homework : Questions Question 7: How do local area networks (LANs) differ from metropolitan area networks (MANs), wide area networks (WANs), and backbone networks (BNs)? One of the key differences between different network types is their geographical scope. A local area network, or LAN, is made up of a smaller group of computers linked together and located in the same small area such as a room, a floor or a building. A backbone network, or BN, is a larger network which connects multiple LANs, WANs, MANs or other BNs together and can range from a few hundred feet to miles in size. Metropolitan area networks, or MANs, normally range in size from a few miles up to thirty miles and LANs and BNs from different areas to each other as well as to WANs. Wide area networks, or WANs, can be hundreds or thousands of miles in size and connect MANs and BNs across these distances. Question 14: Explain how a message is transmitted from one computer to another using layers. The message is first created at the application layer using a software application. This software translates the message based on the protocol being used to transfer the message and places the necessary information along with the message into a Protocol Data Unit (PDU) which is also known as a ‘packet’. This packet is then passed on to the Transport Layer. The transport layer, using its own Transmission Control Protocol, or TCP, takes the packet from the......

Networking Concepts

...media. Some of its defining characteristics are the high data transfer rate, smaller geographic area and lack of a need for telecommunication lines. Arcnet, Token Ring and other technology standards have been used in the past , but Ethernet over twisted pair cabling, and Wi-Fi are the two most common technologies currently used to build LANs. b) Wide area network (WAN) is a telecommunication network that covers a broad area (any network that links across metropolitan, regional, or national boundaries). Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations. This allows business to carry out daily functions no matter their location. c) Metropolitan area network (MAN) is a network that spans a city or a large campus. MAN interconnects a number of local area networks (LAN) using a high-capacity backbone technology, like fiber-optical links and provides up-links to wide area networks (or WAN) and the internet. MAN also depends on communication channels of moderate-to-high data rates. This network is usually owned and operated by one company, but used by many other companies or organizations. d) Campus area network/ Corporate area network (CAN) This network is made of an interconnection of local area networks (LANs) within a limited geographical area. The networking equipment’s (switches, routers) and transmission media (optical fiber, copper plant, and Cat5 cabling) are almost......

...NETWORKING Networking Paul F. Scheelk NTC/360 Network and Telecommunications Concepts Instructor: Anthony Bruno University of Phoenix 1. What is the range of usable IP addresses for the following IP subnet? What is the broadcast address for the subnet? 10.150.100.96/27 The range of usable IP addresses is 10.150.100.97 – 10.150.100.126. The first and last addresses are not usable and cannot be assigned to hosts as one is used as the broadcast address, 10.150.100.127 and 10.150.100.96 is the address for the sub network. When initially determining the usable addresses the /27 provides the information that the first 27 bits are network and the remaining 5 are host addresses. The subnet address would be 255.255.255.224. 2. Describe and explain the difference between circuit bandwidth and network throughput. Focus on networking. Communication networks using Ethernet or other protocols distinguish throughput as the average rate of successful packet delivery over a communication channel. The information is passed over a physical or logical link such as Cat5, 5A or 6 or media such as coax and fiber. It is also measured over a wireless network. It is usually measured in bits per second (bit/s or bps), and/or data packets per second or time slot. Throughput is the actual speed that the data is being transmitted. Bandwidth on the other hand is the maximum speed in which packets can be sent or received. Bandwidth is almost always a higher rate than throughput. 3.......

Network & Telecommunication Concepts

...[your name here] NTC360 Network and Telecommunications Concept Associate Professor Anthony Bruno January 04, 2011 The purpose of this paper is to describe an OSI (Open Systems Interconnection) Model with details about each of the seven layers. The OSI reference model adopts a layered approach, where a communication subsystem is broken down into seven layers, each one of which performs a well-defined function. Additionally it is important to understand the purpose of the OSI model in the overall networking architecture especially as it relates to the TCP/IP (Transmission Control Protocol/Internet Protocol) Architecture, which also consists of layers each playing a particular role in the networking design. Generally speaking, the network protocol layer, which is similar to the data and network layer of the OSI model includes the protocols that allow clients and applications to send data over the network. This includes TCP/IP, NWLink (IPX/SPX), NetBEUI, Infrared Data Association (IrDA). However, the purpose of this document is to focus on the relationships between the OSI model and the TCP/IP architectures, and how they may interact together. Finally, as demonstration of this relationship a visual diagram has been provided to depicts how the TCP/IP layers correspond to the OSI model and layers. To begin with, it is important to understand the seven different layers of OSI Model and the functions they provide in the networking architecture. Below is a list of......
