Spectrum Management As Seen From The Master - Motorola PTP 300 series User Manual

Web Page Reference
Important NOTE: Spectrum Management uses the 99.9% percentile as the prime interference
measurement. All subsequent references to interference level refer to this percentile measurement.
The display of statistical measurement on the spectrum management page always shows a statistical
summary of all channel measurement. The statistical summary is controlled by the Statistics
Window attribute. This attribute defaults to a value of twenty minutes, which means that the
mean and percentile values displayed for each channel are calculated over the 20 minute period.
All channel decisions are made using the values computed over the statistics window period.
8.3.7.4 The Spectrum Management Master / Slave Relationship
The Spectrum Management operates in a master / slave relationship. The master is assumed to be
the link master configured during installation. All Spectrum Management configuration changes
MUST be performed from the master. To enforce this, the Spectrum Management web page has
a different appearance depending if you are viewing the data from the master or slave.
All configuration changes are applied at the master only. These changes are then messaged from
the master to the slave. Any Spectrum Management configuration messages received at the slave
are stored in non-volatile memory. This enables both master and slave to keep identical copies of
Spectrum Management configuration data in their non-volatile memories. It is therefore possible
to swap master and slave roles on an active Point-to-Point link without modifying Spectrum
Management configuration.
