Plan an effective IT infrastructure based on the needs of an organization - Essay Example Despite their growing popularity, cable companies have encountered huge costs of replacing their local loop cables with fiber optic cables to attain high bandwidths. There only demerit is its decreased throughput resulting from concentrated connections within a geographical area. Unlike other connections, cable companies use DOCSI v3 specifications. T-1 and T-3 are a form of leased line connection capable of attaining a data and voice speed of 1.5Mbps and 45Mbps respectively. The difference in speeds translates to a drastic cost implication for the latter. As compared to other forms of internet connection, leased line service are generally more expensive. The only advantage over other networks is its ability to provide permanent and active data connection without the need for dial up services. In addition, T-1 networks can be customized. With a 24 individual telephone and data line at 56kps, it provides a flexible data rate as per the user needs. Dial up connections require a telephone line to establish a server connection. A â€Å"dial up†number provides a link that initiates the connection process. It is the cheapest of all the services. However, the speed and stability provides a challenge. With a maximum speed of 56Kps it lags behind compared to other technologies. An improvement of the dial up connection resulted in ISDN. ISDN uses a circuit switch and a dedicated line. ISDN allows parallel data and telephone transmission (Laan, 2011). Frame relay, just like ATM provides high speed, packet-switched service for sending data between two local or long-distant regions. Both are layer 2 protocal meaning that they can be used in a twisted pair and fiber optic cable. However ATM differ from frame relay in a number of ways. ATM incorporates a mechanism where data is sent in a small 53-byte packages referred to as cells. This splitting of cells into small packages promotes efficient data
