...VOIP Richard Fuquea IT/242 July 20,2014 Joseph Guin VOIP VOIP is a relatively new technology and can be a great way for businesses to improve their communications and maximize their profits as well by saving them money in their communication costs. The flexibility of VOIP also allows for a greater range of options when it comes to telephony. When removing a standard PBX dedicated line and changing over to an internet based VOIP network telephone solution, you can look at many case studies and see that for the most part, the solutions provided by VOIP have improved the companies’ profits and the overall productivity as well. One such case study is the case of the Southwest Airlines Federal Credit Union.("Http://creditunions.fiserv.com/convergeit/contentdocumenthandler.ashx?documentid=4233", 2010) They switched their call center over from a normal PBX based telephone service to a VOIP service to better provide to their customers with a faster and more reliable service and to help bring down cost for themselves by combining their internet and voice services into one main line. Eliminating the PBX phone system allowed them to bring in a fiber optic connection that allows for faster internet speeds as well as having enough bandwidth to have a VOIP connection. Eliminating the PBX connection also allowed for the VOIP connection to be set up so they would have much less maintenance and can be more flexible in the way they have their telephone system set up. They can reconfigure...

...Running head: WAN DESIGN WAN Design for Acme Manufacturing UoP Student Axia College of University of Phoenix WAN Design for Acme Manufacturing Acme Manufacturing is a rapidly expanding company that is headquartered in Atlanta, Georgia. The headquarters building houses corporate operations, marketing, administrative staff, and accounting. Across the street from headquarters are the engineering and sales offices. Acme also has distribution offices in Chicago, Phoenix, and New York. Having just acquired a manufacturing facility in China, the company is now in need of a WAN that will allow each office to securely communicate with one another. Acme will also need a telecommunications system that facilitates communication in the most efficient manner. In order to achieve the desired connectivity, an array of products and services will be necessary. Logical Network Design The network topology used for Acme’s WAN should be a star topology with each site having only a direct connection to headquarters; the benefit is that network administration is centralized. The engineering and sales offices will connect to headquarters over the public WAN through a VPN configured with L2TP and IPSec for security. The manufacturing facility in China can be linked to headquarters through a leased satellite connection. Acme should lease three fractional T1 leased lines that extend from the headquarters in Atlanta to the distribution centers, one line each to Phoenix, Chicago, and New...

...Wireless Signals June 29, 2011 IT242 Wireless Signals There are four different types of wireless signals in the spectrum. These are radio signals, microwave, satellite, and infrared signals. Each of these types has their proper uses as well as limitations. Radio frequencies include VHF, UHF, and shortwave radio. These are used to get a station on your car radio or to tune into a television station. Limitations of radio frequencies include distance degradation compared to bandwidth space in low frequencies. High frequencies tend to need a direct line-of-sight to get a good signal. Electrical equipment can interfere with all frequencies of radio signals. Microwave signals use electromagnetic energy to send signals at a higher frequency than radio. These signals are used in telecommunication, WIFI, and Bluetooth technology. As with radio communication, microwaves are also susceptible to interference from other electrical equipment. Satellite signals are relatable to microwave transmissions. A satellite is in orbit that sends and receives signals to receivers. The most common use for people are television, internet, and mobile telephone services. A major limitation that I run into is stability. When a storm comes through we can loose our signal due to line-of-sight issues. The final wireless transfer style is Infrared. IR systems use light to send signals. This type is used in remote controls, Palm devices, and laptops. The light...

...internet. VIOP passes digitized voice data. The advantage is more communication through the same amount of bandwidth. Public Branch Exchange (PBX) is a small telephone network within a company. This network has several lines to a local phone service to allow calls to go in and out of the company. The PBX internal calls are routed internally, and any calls to the outside take one of the available outside lines. VOIP can be used in a PBX system. This could be an advantage giving the company seamless integration for use of the same phone to dial outside and internal calls, even international access.

...Switches and Router Christina Bennett IT242 Switches and Router One of the main reasons that Cisco is number one in the enterprise networking market place is their Internetwork Operating System (IOS).The IOS provides a similar function to Microsoft Windows or Linux: it controls and manages the hardware it is running on. Basically, the IOS provides the interface between you and the hardware, enabling you to execute commands to configure and manage your Cisco device. “Originally, the IOS was developed for Cisco routers, but over the last few years, Cisco has been porting the IOS to it so there platforms, including the Catalyst switches”. (Cisco.com) There are actually many ways of accessing a Cisco device, including the following: console, auxiliary (only certain Cisco routers), telnet, web browser, and an SNMP management station .A console interface provides serial connection access to a router— with console access, you can enter commands in a text-based mode. In order to access your Cisco device from a remote station, however, you first need to create a basic configuration, including IP addressing. Therefore, to perform your initial configurations, you need access to the console port of your Cisco device. Before you can actually begin configuring your Cisco device, you first have to connect it to your network and set up a terminal connection to its console interface. No two routers are setup in the same manner; however, the command modes they use are pretty much alike...

...VLAN Plan Marcus D. Lewis It242 06/19/11 Ms. Latrea Shine The benefits of Creating VLAN VLAN’s enable the logical grouping and of end stations that are physically dispersed through a network. When users on a VLAN move to a new physical location but continue to perform the same job function, the end-stations of those users do not need to be reconfigured. Similarly, if users change their job function, they need not physically move: changing the VLAN membership of the end-stations to that of the new team makes the users' end-stations local to the resources of the new team. Since broadcasts frames are targeted and processed by all devices that create smaller domains to reduce overhead and limit resource utilization. Only those workstations in need of receiving specific broadcast or multicast traffic can exist on the domain, preventing other devices from receiving unnecessary traffic. The use of VLANs to create broadcast domains also eliminates the need for routers to handle this function, permitting operation at lower latencies compared to routers under heavy load. VLAN’s extends beyond conventional or single LAN’s to form a group of LAN’s. A VLAN can be created to provide groups of users who will be transmitting data among themselves at high volume, reducing the impact on all other workstations. These user workstations do not have to be physically moved or located near one another, since the workgroup is virtual environment and created within the switching software...

...Travis Luther IT242 Week 2 VoIP Voice over Internet Protocol (VoIP) is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular phone line. The technology was introduced in 1995, and has developed into an enormous enterprise since then. I will be presenting an overview of the technologies that brought VoIP to fruition, the methods of connecting, benefits, and drawbacks. IP Telephony allows organizations to reuse their existing network infrastructure. With IP Telephony, employees can use IP handsets or softphones anywhere on the corporate network. Generally only a single Ethernet port is required to provide both desktop and IP Telephony (voice) services. Power over Ethernet using the 802.3af standard or pre-standards based power can be used with great advantage throughout an IP Telephony environment to power other network appliances such as 802.11a/b/g wireless access points, IP video surveillance cameras and IP phones. IP Telephony systems also provide the advantage of lower cost moves/adds/changes administration allowing employees and departments to more easily move from location to location without the burdens of administration and service interruption. Because IP Telephony works with packet networks, the model of support used for IP Telephony can be the same as the one used for the desktop, thereby reducing and simplifying staffing requirements. Since the IP phone or softphone is an intelligent endpoint on the network...
