Thanks, that helps immensely. Now, how can multiple pieces of data be sent at the same time (i.e. the bandwidth of the line)? Do different voltages not interfere? Or are the amplitudes added?

In an analog line, what are the signals? Are they electricity? Are they sound waves? What is the difference between an analog line and a digital line?

With a DSL connection, the digital information is converted into analog as the phone line is analog. How would, for example, a byte, be sent over an analog line? Which part of the analog signal determines the data? For example the byte with binary digits 10101010, would a higher amplitude signal be sent for the 1s and a lower amplitude for the 0s? And what is the time gap between the bits? I.e say there is a 1ms gap between the bits, the analog line would be in a high amplitude state for the first ms, low for the next, high for the next..... or is that the completely wrong idea? Can someone please help me with this? Thanks.
