In this case, the user has configured modulation profile number "3" to be available to upstream channels
wherever they are configured to apply it. Note that this modulation profile has been configured to operate
with a 16 QAM modulation scheme. The default modulation scheme for any upstream profile (if it is not
set to 16 QAM) is QPSK.
Later in the configuration file example, upstream port 0 on the cable modem card installed in slot 5
utilizes both the spectrum management and the modulation profile configured in the sample.
cable upstream 0 spectrum-group 1
cable upstream 0 modulation-profile 3
