Building and constructions Communication systems Essay

Building and constructions Communication systems - Essay Example In the building, over 550 fibre optic data cables are running from the MDF which provides the ability to virtually access any room in the building. The fibre optic cable used in the building is half lucent laser-speed multimode fibre and half lucent single-mode fibre. In the building more than 45,000 meters of fibre optic cable used. This cabling enables each computer to have a 10,000 megabit per second (10Gigabit) connection speed. In the building, there are approximately 450 telephone lines that end into the MDF telephone cubes, with about 60 kilometres of lucent Giga-speed cables.Telstra, the main telephone service provider in Australia also handles the telephone services for the interpro building and the VOIP is not implemented yet. The computer network in the interpro building is based on 540 desktop computers. The network also gives wireless access to interpro network via three wireless routers distributed in each floor of the building. These wireless routers give access to more than 800 wireless devices such as PDAs, laptops or cell phones. Computers are originally in the network but they can also be unplugged if necessary. Wireless routers have an adapter which allows a cable from the LAN to be plugged in. There are also several output ports for cables which can be connected to the rest of the LAN. Each of these wireless routers support 255 wireless devices and has a unique security setting to prevent the damage to the whole building network if a hacker entered the LAN through a wireless router. All access points are equipped with firewall software that controls the flow of data. There is also a monitoring system that shows the status of the network for each floor. The interpro company's building has three floors and each floor uses a separate LAN for security issues. These LANS are connected to each other and they form a small WAN. The whole network is based on cable LAN and wireless LAN. The building has three servers which all the data for each floor is passed by. There are 400 hub-switch provided links in the LANs and as stated before, there are three wireless routers which provide the wireless access for wireless devices both to the building network and the Internet. At the first floor, there is a main server room which has a cavity for cable runs. Each floor at the company has a star topology and all the devices are connected to the main server. Each server on each floor has a bus topology to access two other servers at other floors and the main DSL cable which enters to the building connects to the bus network after the data enters through a firewall.
