Inverse multiplexing means:
a. combining several low speed circuits to enable them to be transmitted across one high speed circuit
b. multiplexing from the terminal to the host, rather than from the host to the terminal
c. combining high speed circuits to enable them to be transmitted across one low speed circuit
d. inverting the frequencies used for transmission across a low speed circuit for switching to a digital circuit
e. multiplexing to a codec, rather than to a modem
Answer: combining several low speed circuits to enable them to be transmitted across one high speed circuit
