MODCOD Filter
To activate the MODCOD filter:
1.
Check the ‘Activate’ box. The table now appears coloured (instead of grey as it was when
the feature was inactive. Initially, there is no selectivity, and all legal MODCODs are ‘Not
filtered’, i.e. they will be passed through to the output interfaces.
2.
Use check boxes above each column, and to the left of each row, to activate the filter for
specific modulation types or code rates. Alternatively, check individual combinations to
toggle the state of the filter between ‘Not filtered’ and ‘filtered’.
In the example shown in Figure 4.30, the user has allowed only QPSK MODCODs from rate 3/5 to
rate 8/9, inclusive. Base-band frames transmitted on all other MODCODs will be discarded.
