...WAN Design Jason Johnson University of Phoenix: IT/242 October 1, 2014 Acme’s WAN Design With Acme’s headquarter located in Atlanta, Georgia and quickly expanding to China and then across the United States, Acme Manufacturing is a top tier company that in turn needs a top tier WAN network to help tie together it’s various locations. Along with Acme’s many other needs they also want to install a telecommunications technology like PBX or VoIP to facilitate interoffice communication. Acme Manufacturing wants to build its network on the principles of security and usability. The following is an outline of the recommendations for their WAN implementation for this company. Network Design 1. Topology The first consideration for Acme’s new network is the topology to be used. The Atlanta office serves as Acme’s headquarters and because the company is quickly expanding across the globe I believe that the star topology is the most suited for their needs. Star networks are easily expanded upon and doing so does not interrupt the other locations. Centralized administration is a strong selling point for this topology as well. A powerful mainframe computer and an array of Cisco Catalyst switches will serve as the network’s hub. Figure 1 below represents the proposed WAN topology: Figure 1- Proposed Acme WAN topology Figure 1- Proposed Acme WAN topology ATL (HQ) T1 T1 T1 PHX CHI CHINA NY ATL (HQ) T1 T1 T1 PHX CHI CHINA NY 2.

In carrier networks VoIP has been mainly deployed in enterprise networks or as a trunking technology to reduce transport costs in voice ...

...different Unified communication platforms. Softphone- is a software program that allows you to make calls over the internet using a computer. VoIP- voice over IP is voice information over the internet that sends the voice information in a digital form rather than the traditional telephone network. Half Duplex- is a computer circuit allowing the transmission of signals in both directions but not at the same time. Full Duplex is when both parties communicate as one. It allows data transmission to more than one device. PBX working on premises within an enterprise that (private branch exchange) is a private networking and switching system operates with traditional telephone lines One of the examples my team discussed of Softphone was Magic Jack because it is a phone service that is ran through internet and not actually wired through hardwire equipment. An example of VoIP would be the phone line being connected through your cable modem vs. the traditional way it use to be wired through your home. A great example of Half Duplex is a walkie talkie because you can talk to each person back and forth, however you have to take turns speaking no two people can talk at the same time. An example of Full Duplex would be a three way call because everyone is communicating at one time as well as your connected to more than one device. An example of PBX would be the phone lines in my office we have 10 phone lines linked to 1 telephone number as well as our fax lines. We all had different examples...

...the world that needs to be networked collectively. All the remote locations need to communicate effectively with the main headquarters that is in Atlanta, Georgia. The two buildings that house the headquarters are located across from each other. One building is used solely for corporate operations whereas the other building is for staffing the sales and engineering department. PBX vs VOIP PBX (Private Branch Exchange) is a system that has been around for a while. This allows users to communicate to other users in an office, even without an outside line connected. In a normal environment, the user would have to dial a specific number (or code) to access an outside line. In this way an end user could dial a number that would stay internally. A PBX also allows the users to share the lines that are accessible to the company. If a customer were to call the company on the main line, the receptionist could transfer that call to the salesperson. PBX systems also allow for many other features such as: Voice mail, Caller ID, Programmable phones, Extensions, Hold Music, and ect. The biggest downside of a PBX system would be the number (or extension) is attached to the line. Therefore, if a user changes offices they would physically change the wire on the punch block. Another downside is the phones are normally proprietary, meaning that you cannot go buy just any phone and expect it to work. The phone service that is needed...

...ISDN & DSL Broadband Connections Thiago C. Gandarillas ISSC 340 American Military University Prof Kageorgis Throughout this paper we will review all the concepts regarding the ISDN and DSL technologies, definition, usage, benefits overall and costs. We will also compare to newer technologies overall to understand where our connections capabilities were and where they are over today’s date and where it is going. ISDN (Integrated Services for Digital Network) is a standard way to communicate digital transmission of data, voice, video and other network devices at the same at the same time over the traditional ‘’phone lines’’, basic telephone copper wires, called RJ-48 connectors. Prior to ISDN, the telephone system was only related to voice transportation, with very limited to none data service availability. The ISDN has the capability to support at least two or more connections at the same time, in any combination of voice, data, fax and video over a single line. At first ISDN speeds were only at max 128 kbits over download and upload speeds. Eventually carried over an E1, speed rates could be at 2048 kbps. (PC Magazine, 2001) ISDN-BRI (Basic Rate Interface), service is delivered through a pair of standard telephone copper wires at 128 kbps rate. Following available interfaces and their characteristics: * U Interface, usually a non-North American network, two wired interface between the network terminating unit and the exchange. * T Interface is a serial...

Victor, CHA, CHE, CHS, CMP Fairleigh Dickinson University, Madison, NJ 07940. Contact: jvictor@jeffreyvictor.com Analysis of Repurposing Underutilized Hotel Rooms Inventory as Executive Office Space 1 Abstract When hotels are built, the number of rooms built into inventory becomes a static item. Due to the physical nature of construction, the number of rooms become an inflexible and perishable commodity. In looking at the growing nature of the Executive or Serviced Office industry and the similarities between their product and a hotel’s offerings, it has been theorized that there are revenue opportunities in deploying a serviced office product in pre-existing hotels. Through an analysis of industry trends, demand for offices, product needs and revenue opportunity, a financial model has been developed. After reading this paper, the reader will be able to understand what a serviced executive office is, the similarities between that product and a hotel product and understand how to analyze revenue to determine the financial impact of repurposing a number of rooms as executive offices. They will then be able to utilize the model contained herein to determine if repurposing rooms in such a manner...
