Networking Essay
1. Describe a local land line phone system on the following Landline Telephone Components:
a. Local Loop: A local loop is a network or circuit that connects a group of telephone customers to the edge of the service provider’s network, no larger than 3 miles.
b. Central Office: A central office is responsible for providing certain services to the local loop, such as, call routing, signaling, digit collecting.
c. Local Exchanges: A system of devices or switches that direct local calls. Commonly called a switchboard.
d. POP: POP (Point of Presence) is the location or interface point of a communicating party. Comparable to an internet POP such as a router or switch.
e. Long Distance System: The long distance system is a service for making long distance calls. Before direct dialing, this was done though several switchboards spanning many different areas.
f. Fixed Line: A fixed line, also called a landline, is a telephone that is physically connected to the local loop via telephone line. This differs from a cellular phone which uses radio waves to connect.
2. Define and describe the following Telecommunications Network Components:
a. Cellular Telephones: Cellular Telephones use radio waves to communicate with cellular towers that direct the call. They currently use 3G and 4G connections for both voice and data.
a.i. Voice: Voice calls are not too unlike fixed line calls; the difference being that is it transmitted wirelessly. The call is transmitted via radio waves to a cellular tower, which is then routed through the service provider and to the party on the other end.
a.ii. Data: Data is commonly called “mobile internet”. Data is sent through radio waves in either a 3G or 4G connection, which streams data to and from the phone, much like a computer connects to the internet.
b. Telephone Network Topology: Telephone network topology refers to in what way the particular telephone call is routed. Much like the Bus or Star topology in computer networking.
