DETAILED DESCRIPTION OF PROBLEM:
Change to section 6.6.6.8.13.1.3 in CM-SP-CCAP-OSSI3.1-I05-150910 to differentiate between minimum BW and
minimum configured BW (account for guard bands). No REQ or test plans affected.
Added requirement in section 6.6.6.8.16 that the CCAP MUST reject configuration of exclusions if the total
number of active subcarriers would fall below 6400 / 25 = 256 for 25 kHz subcarrier spacing or below 10000 / 50 =
200 for 50 kHz subcarrier spacing.
