Which DSL technology provides higher downstream bandwidth to the user than upstream bandwidth?
A company is looking for the least expensive broadband solution that provides at least 10 Mb/s download speed. The company is located 5 miles from the nearest provider. Which broadband solution would be appropriate?
What mobile broadband communication Layer 2 technology uses a special coding scheme to assign each transmitter a specific code?
What are two features of wavelengths in the electromagnetic spectrum? (Choose two.)
They are the rate at which current or voltage cycles occur.
They are the distance from the peak of one radio wave to the peak of the next radio wave.
They are the distance from the peak of one radio wave to the trough of the next radio wave.
They are calculated by the speed of propagation of the electromagnetic signal divided by its frequency in cycles per second.
They are calculated by the number of waves per second.
What advantage does DSL have compared to cable technology?
DSL upload and download speeds are always the same.
DSL is faster.
DSL has no distance limitations.
DSL is not a shared medium.

interface gigabitethernet 0/2
pppoe-client dial-pool-number 2
ppp chap hostname 2.
Which medium is used for delivering data via DSL technology through PSTN?
How is voice traffic affected when the customer uses ADSL technology?
No special equipment is needed to separate voice and data signals.
Voice traffic is interrupted if the ADSL service fails.
ADSL signals can distort voice transmissions.
Voice signals are on a separate wire pair from ADSL signals.
