Question 1

With asynchronous digital subscriber line (ADSL), the upstream speed is actually higher than that of the downstream speed.

Accepted Answer

A) True 
 B)False  False

Question 2

Explain what is meant by a converged voice and data network.

Accepted Answer

A converged voice and data network refers to a single network infrastructure that is able to carry both voice and data communication. This means that instead of having separate networks for telephone and computer data, a converged network allows for the integration of both types of communication over the same network. This can be achieved through technologies such as Voice over Internet Protocol (VoIP) which allows for voice communication to be transmitted over the same network as data. By converging voice and data onto the same network, organizations can benefit from cost savings, simplified management, and improved efficiency in their communication infrastructure.

D)  may be placed in one central location and feed multiple regions 
E)  all of the above

Accepted Answer

A)  calls no longer need to go back to the class 5 switch in order to be switched through the network 
B)  more calls are allowed to travel across the same number of facilities
