will also eliminate the amount of missed calls, busy signals, and not being able to contact a manger when needed. The VoWLAN connection will be provided by the Cisco wireless routers The OfficeServ VoWLAN supplies a wireless signal to all the phones in the area and will act like a cell phone network located within the company.

All this technology is great, but what if there is no service available or one of wireless routers goes down? When the service provider is having outage issues the T1 line that is located at DelMar will be used be as backup internet. In the event of a nature disaster a T1 line will be used to help reach the desired bandwidth from server to a switch for each individual router. This line will be used if a wireless router goes down and will provide an uninterrupted service for that particular site not to lose communication. The backup power supplies will also be increased in size because of the equipment that is on the network.

Detailed design process and specification

According to Patton-Fuller the IT data center hosts a Hospital Information System (HIS) server, Windows Exchange Server, Internet Server, Remote Access Server (RAS), Cisco routers, a network gateway, and workstation (). Patton-Fuller declares the IT Data Center houses an IBM Series Z9EC mainframe server using the LINUX operating system with DB2 as the relational database management system (RDBMS) tied to a 10 terabyte disk storage device connected through a 4GB FO link backed up by an APC UPS battery system.

According to Patton-Fuller the IT department uses an IBM system X3250 running MS Windows Server 2003 Enterprise as its Windows Exchange Server. Patton-Fuller also uses an IBM system X3250 as its Internet server, using Linux and Apache operating systems, connected to a Cisco Router model 7609. According to Patton-Fuller the RAS server is an IBM system X3250, running the Linux operating system, connected to a Cisco ASA 5510 Virtual Private Network (VPN) router. According to Patton-Fuller the data center workstations are Apple IMAC’s running MAC OS X, Leopard, and Windows XP Pro operating systems.

All devices native to the IT datacenter connect to Patton-Fuller’s Ethernet LAN network through a 1000 BaseT CAT 6 cable system. According to Patton-Fuller the IT data center also hosts a network gateway that connects both 1000 BaseT (cable) and 1000 BaseF (FO) media to the network. The aforementioned configuration successfully connects the administrative and clinical areas to Patton-Fuller’s network.

Physical system model

Systems modeling or systems modelling is the way to deal with the investigation of the utilization of models to envision and build systems in business and IT advancement. In business and IT advancement the expression "systems modeling" has different importance. System Modeling can allude to examination and configuration endeavors, reenactment as well as system motion, and an investigation of the numerous employments of these models. There are distinctive ways to deal with displaying: Agent based information and scientific demonstrating.

Quality administration embraces various administration rule that can be utilized by top administration to direct their associations towards enhanced execution. Standards, for example, client center, administration, individuals’ association, the procedure, system way to deal with administration, persistent change, actualities, and a common advantage (Wellstead, 2000).

Choice making is a thinking or enthusiastic procedure which can be judicious or unreasonable. The subjective point of view is that the choice making procedure must be viewed as a persistent procedure incorporated in the connection with nature. From a regulating viewpoint, the examination of individual choices is concerned with the rationale of choice making and sanity and the invariant decision it prompts it can be in light of unequivocal presumptions or implied suspicions. In choice making, goals must be built up and put in the request of significance. It is an advantage to likewise have an option strategy and assess it against the goals. Whichever elective that is best ready to accomplish the greater part of the destinations is the one you utilize. In the wake of picking, further assessment is expected to get ready for conceivable extra outcomes. At that point your choice is made.

Practical demonstrating, Business procedure displaying, and Enterprise displaying are diverse levels of many-sided quality business and IT advancement system demonstrating. System demonstrating can be isolated into: Systems examination, hard system displaying or operational exploration demonstrating, soft system demonstrating. What’s more, particular sorts of system demonstrating, for example, complex system displaying, dynamical system demonstrating, and basic system demonstrating likewise exist (Wellstead, 2000).
