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 was not going to use his real name, the business name or any of the actual phone numbers in my paper also helped. With this assurance and the promise of a copy of the paper in place, he agreed to an interview on the telecommunication system used to support his optometry clinic.
The current telecommunication system As we began to talk about Doctor Martin’s optometry clinic and how his current telecommunication systems serviced the business, we started with the history of his business. Doctor Martin stated that he started with a small office in his home about forty years ago using an analog rotary phone and Plain Old Telephone Services (POTS) line. From there he moved to a clinic and shared a Dual Tone Multi-frequency (DTMF) system with Private Branch Exchange (PBX) that gave the small four doctor office a centered switch network with more lines to handle calls and an intercom system for paging and call holds. The clientele and suppliers were local to the area so the partners did not feel the need for an 800 or Wide Area Telecommunications Service (WATS). Upon leaving that group setting, Doctor Martin took out a lease on his current location. Here he uses a central office exchange system that provides his business with a four digit intercom number to connect and transfer calls to the internal examination rooms and main office, direct inward dialing (DID), 800 service, voice mail and caller ID. His internet access comes from the same provider using a shared T1 line. Receiving all of his communications services from one provider has helped him manage his costs as it gives him the ability to use social media to advertise his business. He stated that he likes his current location in a small strip mall and knows that his central office exchange system and T1 line is shared with the other eight stores in the complex. He thinks that losing some of the autonomy of a private system for a shared one is cost effective in that the provider is responsible for service repairs and equipment. System upgrades are offered by his provided that accommodates his business specific equipment at reasonable fees with minor interruptions for service changes and he believes CAT 5 wiring is in use throughout the system. We concluded this conversation with a question of data storage. Doctor Martin stated that he takes advantage of his provider offsite data storage option and runs nightly system backups with them and an additional private source.
Term Definitions
Rotary and Dual Tone Multifrequency (DTMF)
• Rotary refers to an analog system that uses a mechanical switch and a series of clicks to dial phone numbers through interrupted electrical pulses.
• Dual Tone Multifrequency (DTMF) is digital and instructs a phone switch system to dial a number using tones activated by pushing buttons on a key pad.
Wide Area Telecommunications Service (WATS) and leased lines
• WATS is a dedicated line and number that in-coming calls are routed through similar to an 800 number in use and ability but more cost effective based on call volume.
• Leased lines are dedicated connections between two parties or places that share information solely for the operation of their business. The advantage of a leased lines is traffic reduction as it is not public or used for general duties, speed and, control of data.
Private Branch eXchange (PBX) and Centrex
• Private Branch eXchange (PBX) is an in-house centered switching network used to handle both internal and external phone calls. It can also handle an internal intercom as all the equipment used is managed internally by the company using it.
• Central Office Exchange (Centrex) is similar to the PBX in function and services it provides but, the switching services and equipment are external to the company that uses it. The company providing the service owns, operates and maintains the equipment needed to run the system.
The layers of the International Organization for Standardization-Open Systems Interconnection (ISO-OSI) model
• International Organization of Standardization (ISO) is a non-governmental organization that developed standards of technological applications for global industry.
• Open Systems Interconnection (OSI) is a model that describes how information moves through a network. It is composed of seven layers with specific network functions. “Each layer performs a defined function for the layer above it and communicates with its peer layer over an interface”( Rowton, 2011). “Please Do Not Throw Sausage Pizza Away” is the phrase commonly used to remember the names and order of each layer. The layers are: • Physical – Bits
• Data Link – Frame
• Network – Packet
• Transport – Segment
• Session – Data
• Presentation – Data
• Application – Data

Concept of Network

...CONCEPT OF NETWORK:  A network can be defined as a group of computers and other devices connected in some way so as to be able to exchange data. In a network of computers, people can share files and peripherals such as modems, printers etc.  Each of the devices on the network can be thought of as a node (hub),each node has a unique address.  In modern networking, data is transferred using packet switching. Messages are broken in to packets and sent from one computer to another. At the destination, data is extracted from packets and used to reconstruct the original message. TYPES OF NETWORK: Broadly there are two types of network:  Local Area Network (LAN) – It confined to a particular geographic area such as a building or a college campus.  Wide Area Network (WAN) – It covers cities, countries and continents. NETWORK TOPOLOGY:  A topology describes the configuration of a communication network. The way in which the elements of a network are mapped or arranged is known as a network topology. A topology describes the physical and the logical interconnection between the different nodes of a network. Types of Network Topologies 1) Star Topology Adarsh S Kawale PRN: 12020941011 In this type of network topology, each node of the network is connected to a central node, which is known as a hub.

Ntc/411 Network Management Paper

...Network Management (Your Name) NTC/411 (Current Date) (Instructor’s Name) Network Management Network management is an integral part of any IT system. Managing a network can be a tough task at times and managers have to decide on the best approaches for their network management. In this paper we’ll discuss out-of-band vs. in-band network management. We’ll also provide some examples of some of the protocols that perform in both types of network management and how enterprise systems are affected by the network management techniques along with business intelligence systems. In general, in-band and out-of-band refer to whether the solution or technique sits in the flow of the network traffic or out of the flow. Some IT professionals say that in-band network management provides better security than an out-of-band approach. Before we get into too much detail we need to discuss what an out-of-band and an in-band network management approach are. In-band approaches require devices or hardware to sit in the flow of live network traffic, often where endpoints access the network so that all client traffic has to pass through them. When a network manager decides to deploy an in-band device then they will be able to provide pre-connect and post-connect security. Network adapters are the most common type of in-band remote management hardware devices (Nevis Networks, 2007). In a Windows environment you can use remote access connections to manage......

What is the range of usable IP addresses for the following IP subnet? What is the broadcast address for the subnet? The range of usable IP addresses is – The first and last addresses are not usable and cannot be assigned to hosts as one is used as the broadcast address, and 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 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.......

...Rotary dialing relies on a completely different concept. When using rotary dial, an electrical signal is applied an interrupted a number of times equal to the number the user wishes to dial. For instance, to dial a number 8 a telephone would have to interrupt the electrical signal 8 times. A pause signifies the completion of the first dialed numbered and the system prepares to receive the next number. Voice and Data Communication Systems Voice and data communication systems are the backbones of modern business organizations. Without these systems, business would quickly crumble due to competitors’ ability to leverage such systems to communicate changes in the market and other required business information very quickly. If my business had more than one employee and more than one location, then getting information from one point to the other without a voice or data network could potentially take long enough that my company would lose out on profits to my competitors. In short, voice and data communication systems enable businesses to survive in what has now become a world that moves at the speed of light. In this article, I will describe the voice and data communication systems I use to perform my job as an online reseller.

...I. Definition of the subject Telecommunications technology is defined as physical devices and software that links various pieces of hardware and transfers data from one physical location to another. Computer networks consist of two or more connected computers that carry information across a wired or wireless technology. The basic hardware needed for the network to operate is a router which directs traffic to different computers and a network card which allows the computers to communicate. These networks include computers, internet services and communication tools which include cell phones, video conferencing, and email. The internet includes the World Wide Web, chat, email, and voice over internet protocol (VoIP), unified communications, and virtual private networks (VPN). Definitions of each term are defined below. • World Wide Web is the most popular internet service. • Chat allows individuals to “talk” live holding and interactive conversation. • Email allows messages to be exchanged from person to person within seconds. It is faster and less expensive than any other delivery method such as the postal or overnight delivery services. • Voice over Internet Protocol (VoIP) allows users to send calls using broadband internet. It allows users to avoid long distance and toll charges normally charged by local companies. “VoIP can reduce communication and network management costs by 20 to 30 percent.” (Laudon, 2010, p. 269) • Unified communications......

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......

Introductory Network Concepts, Network Standards, and the Osi Model

...Introductory Network Concepts, Network Standards, and the OSI Model 1. There are many reasons for a company to network its computers, some are as follows; Share software, information with others on networks, cheaper than buying individual software and hardware for each standalone especially if the software often offers deals for amount being purchased, e-mail between network users, and flexible access from any computer on the network. 2. Two fundamental network models are peer-to-peer(P2P) or Client/Server. In a P2P network, every computer can communicate directly with every other computer, and no computer on this network has more authority than another. On a client/server network every computer acts as a client or a server. 3. There are 3 types of networks depending on how much territory they cover, they are LANs, MANs, and WAN networks. LAN networks cover a small area like one building or one office. MANs cover multiple buildings like a handful of government offices surrounding a state capital. A WAN network is one that connects two or more geographically distinct LANs and MANs. 4. A server is a computer on the network that manages shared resources. 5. A client is a computer on the network that requests resources or services from another computer on a network. 6. A NIC or Network Interface Card is the device that enables a workstation to connect to the network and communicate with other computers. 7. A NOS or Network Operating System is......
