Question

Select the correct statement(s) regarding asymmetric digital subscriber line (adsl).

a. adsl is provisioned over twisted pair local loops
b. adsl can support both analog and digital signals simultaneously
c. full duplex is accomplished using separate transmit and receive frequency bands (i.e., fdd)
d. all statements are correct

Answer 1

All the statements regarding ADSL provided in the question are correct, including its ability to provision over twisted pair local loops, support for simultaneous analog and digital signals, and full duplex communication using FDD.

Step-by-step explanation:

You are correct in identifying that ADSL (Asymmetric Digital Subscriber Line) has several notable characteristics:

• ADSL is indeed provisioned over twisted pair local loops, which are the traditional copper wires that form the telephone network.
• It can support both analog (like regular voice calls) and digital (internet data) signals simultaneously by separating the frequency spectrum used for each type of signal.
• Full duplex communication in ADSL is accomplished by using separate frequency bands for transmitting and receiving data. This is referred to as Frequency Division Duplexing (FDD).

Therefore, all statements listed in the question about ADSL are correct.
