Equipment Setup -> AMR/Radio Mapping Configuration, Setup
Figure 31. Adaptive modulation (AMR) settings. Example: license allows 32QAM, 16QAM and QSPK.
If antennas have not been aligned, select AMR Non Operation. Adaptive modulation changes the
transmit power slightly which would cause problems during the alignment.
After the alignment is ready remember to select AMR Mode (Used) for the appropriate modulations.
Input the number of E1 and STM-1 channels for each modulation level.
Figure 32. Adaptive modulation E1- and STM-1 settings. 8 E1 channels enabled.
