Hitless and Errorless Step-by Step Adjustments 

ACM works as follows. Assuming a system configured for 128 QAM with ~170 Mbps capacity over 
a 28 MHz channel, when the receive signal Bit Error Ratio (BER) level reaches a predetermined 
threshold, the system preemptively switches to 64 QAM and the throughput is stepped down to 
~140 Mbps. This is an errorless, virtually instantaneous switch. The system continues to operate at 
64 QAM until the fading condition either intensifies or disappears. If the fade intensifies, another 
switch takes the system down to 32 QAM. If, on the other hand, the weather condition improves, 
the modulation is switched back to the next higher step (e.g., 128 QAM) and so on, step by step 
.The switching continues automatically and as quickly as needed, and can reach all the way down 
to QPSK during extreme conditions.
