Understanding DSL and Cable Lines for High-Speed Data Transmission
Which of the following statements about DSL and cable lines is false?
A. DSL operates so it does not interfere with voice telephone service.
B. Cable signals interfere with TV signals.
C. Cable lines provide high-speed data transmission using cable television lines.
D. DSL operates on the same lines as voice telephones.
E. DSL data transmission and telephone conversations can occur simultaneously.
Answer:
The false statement among the given options is B. Cable signals interfere with TV signals. In reality, cable lines are designed to provide high-speed data transmission while coexisting with TV signals without causing interference.
Cable lines use different frequency bands for data and TV signals, allowing both services to operate simultaneously without affecting each other's performance. Cable internet service utilizes the existing infrastructure of cable television lines to deliver high-speed internet access. DSL technology enables high-speed internet access over the same copper lines used for voice telephone services. Since DSL uses a different frequency range than voice telephone services, users can make phone calls and access the internet concurrently without any issues.
