My ADSL provider's twisted-pair lines provide a total bandwidth of 1.1M hertz and the provider provides me with a modem that uses QAM-64 modulations.
• To allow me to stay online while making phone calls at the same time, what technique does the ISP use? Briefly explain how it works. You can assume that a voice channel needs 4kHz of bandwidth.

If the provider uses | of total available network bandwidth for download, what is the overall download speed?

• Is my download bandwidth enough for a youtube video of size 240 pixels by 240 pixels per frame and a frame speed of 25 frames per second? Each pixel needs 3 bits. You need to justify your answers. A simple yes or no won't receive any credit.
