Briefly describe each of the following: CATV, DSL, ISDN, FTTP, T-carrier, and ATM.

Question

What will be an ideal response?

Answer 1

The cable television (CATV) network provides high-speed Internet connections, calledcable Internet service. The CATV signal enters a building through a single line, usually a coaxial cable. This cable connects to a modem, which typically attaches to your computer via an Ethernet cable. Home and small business users often subscribe to cable Internet service.  ?DSL (Digital Subscriber Line) transmits on existing standard copper phone wiring. Some DSL installations include a dial tone, providing users with both voice and data communications. These DSL installations often require that filters be installed to reduce noise interference when voice communications share the same line. DSL is a popular digital line alternative for the small business or home user. ?FTTP, which stands for Fiber to the Premises, uses fiber-optic cable to provide extremely high-speed Internet access to a user's physical permanent location. With FTTP service, an optical terminal at your location receives the signals and transfers them to a router connected to a computer. As the cost of installing fiber decreases, more homes and businesses are expected to choose FTTP. ?AT-carrier line is any of several types of long-distance digital phone lines that carry multiple signals over a single communications line. Whereas a standard phone line carries only one signal, digital T-carrier lines use multiplexing so that multiple signals share the line. T-carrier lines provide very fast data transfer rates. Only medium to large companies usually can afford the investment in T-carrier lines because these lines are so expensive.?ATM (Asynchronous Transfer Mode) is a service that carries voice, data, video, and media at very high speeds. Phone networks, the Internet, and other networks with large amounts of traffic use ATM. Some experts predict that ATM eventually will become the Internet standard for data transmission, replacing T3 lines.
