for all the other channels included in the Standard pattern setting (paging, synch, and six
traffic). Using this pattern setting requires the selection of both a BBX and at least one MCC.
Selecting CDF performs tests using pilot, synch, paging and six traffic channels, however, the
gain for the channel elements is specified in the CDF file.
