The SONET standard will establish a digital

has been designed to take advantage of fibre, in contrast to
wires.

gigabits per second. Since SONET uses multiple
channels to transmit data, each SONET
frame can be
considered to be a two-dimensional table of bytes that is 9
rows high and 90 columns deep. For every

can transmit n number of frames at a given time. Groups of
