1 = Enable; 0 = Disable. BPI+ default = 1.
A change to this setting takes effect when the modem re-registers.
Operational Parameters
All of the CM's Baseline Privacy configuration values are specified in the configuration file downloaded by the CM during
registration or are set to the known default values in BPI+ mode. These values are BP-specific, type 17, configuration
parameters. See the following table.
Caution: BPI requires ALL type 17 parameters to be present and within range in the CM's configuration file. The modem
will be rejected if the defined values are out of range.
Note: BPI+ does not require ANY parameters to be present in the CM's configuration file. BPI+ will choose DOCSIS® defined
default values for any parameter not specified in the CM's config file. If a value is specified in the config file, that value will
be used if within range. The modem will be rejected if the defined values are out of range.
