PROJECT OVERVIEW
Overview
Network design is an iterative process, encompassing the process can be tailored according to each new network or service.
This is an extremely important process which must be performed before the establishment of a new telecommunications network or service. The following figure are some demonstration on how the computers is been networked.
In our project we are supposed to do the network design of the room IT7 at the Bulacan State University(BSU) the building of our college. IT7 has more or less 25 unit of computers.
As we go along doing our project we will discuss about how does the computer on that room will be connected to each other through some devices used in networking.

Checking the Net Integrator components
The Net Integrator package should contain the following items:
- Net Integrator
- Power cord
-
- Category 5 Ethernet cables (3)
- Hard Disk Keys (2)
- Face Plate K eys (2)
- Rails (2) - Rackmount option only
- Tower Stabilization Feet (4)
- Lotus Foundations Getting Started Guide
- Net Integrator Quick Start Guide (th is manual)
- Lotus Foundations CDs
Connecting the Net Integrator
- Ensu re that the Net Integrator has adequate ventilation. Place the back of the unit at least 12”-24” away from the wal l.
- To plug in the Net Integrator:
- Connect one end of the power cord into the power socket, located on the back of the Net Integrator.
- Connect the other end of the power cord into a stand ard 115 Volt A C or 220/240 Volt AC power outlet.
- To connect to a local area network (LAN):
- Connect one end of a category 5 or higher Ethernet cable into Ethernet Port 0, which is located on the back of the Net Integrator.
2. Connect the other end of the c able into your Ethernet hub or switch.
- If you are using a high-speed cable modem or a DSL modem:
- Connect one end o f a category 5 or higher Ethernet cable into Ethernet Port 1, located on the back of the Net Integrator.
- Connect the other end of the cable into your cable modem or DSL modem.
- Turn on the main power switch for the Mark I or Mark II.
- If an automatically assigned IP address, for example, 192.168.0.1 is displayed on the display panel a nd you want to accept this IP address, proceed to the section Configuring Your Desktop in this guide.
- If an automatically assigned IP address is displayed on the display panel and you want to change this IP address, proceed to the section Manually Assigning an IP Addressing in this guide.
- If after 3 minutes, the display panel continues to read Ch oosing Address, this means the Net Integrator is unable to automatically select an IP address. Go directly to the section Manually Assigning an IP Addressing in this guide
Wait two or three minutes as the Net Integrator auto configures an IP address. You now have three options:

WIRING STANDARDS AND PROCEDURE
The hardware components and structure,wires and other elements that contains the room IT7 within the building of CICT,and the software,protocols and the data travel along the wires are the combination known as Local Area Network or LAN.
The following is a list and brief description of the standards and cabling components for the room IT7.
Standards
The EIA/TIA (Telecommunications Industries Association) wiring standards provide guidelines for the network wiring of buildings.The Electronic Industries Alliance (EIA, until 1997 Electronic Industries Association) is a trade organization composed as an alliance of trade associations for electronics manufacturers in the United States. Those associations in turn govern sectors of EIA standards activity.An organization that sets standards for technology industries. TIA (Telecommunications Industries Association) represents providers of communications and information technology products and services for the global marketplace through its core competencies in standards development, domestic and international advocacy, market development and trade promotion programs. The association makes possible the convergence of new communications networks while working for a competitive and innovative market environment. TIA strives to further its 700 members' business opportunities and to promote economic growth and the betterment of humanity through improved communications.
Topology
Star networks are one of the most common computer network topologies. In its simplest form, a star network consists of one central switch, hub or computer, which acts as a conduit to transmit messages. Thus, the hub and leaf nodes, and the transmission lines between them, form a graph with the topology of a star. If the central node is passive, the originating node must be able to tolerate the reception of an echo of its own transmission, delayed by the two-way transmission time (i.e. to and from the central node) plus any delay generated in the central node. An active star network has an active central node that usually has the means to prevent echo-related problems.
The star topology reduces the chance of network failure by connecting all of the systems to a central node. When applied to a bus-based network, this central hub rebroadcasts all transmissions received from any peripheral node to all peripheral nodes on the network, sometimes including the originating node. All peripheral nodes may thus communicate with all others by transmitting to, and receiving from, the central node only. The failure of a transmission line linking any peripheral node to the central node will result in the isolation of that peripheral node from all others, but the rest of the systems will be unaffected.
Passing of Data Packet through unnecessary nodes is prevented by this topology. At most 3 devices and 2 links are involved in any communication between any two devices which are part of this topology. This topology induces a huge overhead on the central hub, however if the central hub has adequate capacity, then very high network utilization by one device in the network does not affect the other devices in the network.
Telecommunications Closet
Telecommunication closet will be located near the center of the CICT bulding.Also known as wiring closet.One on each floor (typically, depending on the floor space and special requirements number may vary).Standards complaint connecting hardware should be used.Specifications about short cables (patch chords) are made.In large office buildings, there will be centralized equipment rooms to house servers, hubs, modems etc.It is the central interconnection point for network cabling.Main cross connections are specified here.
Cat6 Shielded Patch panel 48-Port
Categories of Wire
There are several categories of wire recognized in the EIA/TIA standards. Category 6 wire - four-pair, unshielded twisted pair (UTP) - is the cable of choice because of its 1000 Mbps capability. The network software and hardware other than the cables will determine the actual network speed.
Electrical wiring in general refers to insulated conductors used to carry electricity and associated devices. This article describes general aspects of electrical wiring as used to provide power in buildings and structures, commonly referred to as building wiring. This article is intended to describe common features of electrical wiring that should apply worldwide.
Connectors
All wire cable connectors (jacks and plugs) in the room IT7 Lan installation should be RJ-45 Category 6 connectors.Although used for a variety of purposes, the RJ-45 connector is probably most commonly used for 10Base-T and 100Base-TX Ethernet connections.
