Given a fiber optics line between Alaska and Oregon, with a data capacity of 2.5 Gbits/s, calculate the following:
a. the number of voice channels (64 kbits/s each) that can be carried on this line
b. the number of CDs per second (650 MB each) that can be carried on this line
c. the number of video channels (15 Mbits/s each) that can be carried on this line
