Telecommunications
Components of Telecommunication Networks
Telecommunications Networks consist of components that transfer voice and data over the same system, and Melissa needs to understand the components integral to the system. She has found some key words on which she can search.
POTS Local Loop
The Plain Old Telephone Service (POTS) is a simple network that connects a house to the Central Office of the Telephone Company through a Local Loop. The Local Loop consists of twisted pair cables with a maximum length of three miles.
Digital Subscriber Line (DSL) Local Loop
The DSL System also includes a Local Loop of Twisted Pair Cable that is primarily used to connect computers and other digital equipment as well as telephones. The maximum length of this loop is 11 miles.
Interexchange Hierarchy
A telephone network is basically a lot of local systems interconnected to form one large system. The local exchange serves a group of subscribers (customers) in a local area by physically connecting them with a pair of copper wires. Local exchange carriers (LEC) are local telephone companies that provide service along with other LECs within a designated geographical area. The POP is where the LEC meets the long distance or interexchange carrier (IXC).
Network Topology
The telecommunications network is divided into specific topologies, or segments, to handle each aspect of the information flow depending on the distance from the consumer and the purpose of the information flow. These topologies or segments are
1. Access networks
2. Regional/metro networks
3. Core/long-haul networks
4. Ocean networks
Regional Bell Operating Companies (RBOCs)
As a result of a suit by the U.S. government challenging their monopoly, AT&T divested its local exchange carriers into seven “baby Bells,” or RBOCs, in 1984. These service providers provide most of the fixed-line, wireless, and data services in the United States. A big advantage of the RBOC telecommunications
