Theory of Operation
Example: For 6400bps carrier, QPSK and FEC 3/4, No AUPC or Reed-
Solomon, the bandwidth would be:
Modulation:
6400 * 0.5 = 32000
FEC:
3200/0.75 = 42667
Allocation Factor:
42667 * 1.4 = 59734 Hz
Note: If Reed-Solomon was available, the bandwidth would increase to
65564 Hz.

MIDAS supports full duplex circuits for data and video applications. The full
duplex data and video circuits could be symmetric or asymmetric.
