More on the Thresholds Chapter 8
Data becomes invalidated following a reset. In the example below, the Slave ODU was reset
shortly after 08:45. All data prior to that time becomes invalidated. The only valid items are
the recordings following the re ‐ sync.

stored performance data.
8.4.2 More on the Thresholds
RSL Thresholds
Two RSL Thresholds can be defined. They are used as an indicator of problems in the radio
channel. You can check the RSS from the Link Budget Calculator results during installation.
Values of ‐ 5dB and ‐ 8dB from the current RSS are typical.
TSL Threshold
A counter is maintained, of the number of second intervals during which Tx power exceeds
this threshold.
BBER Threshold
The Background Block Error Ratio is measured as a percentage. The threshold can be set from
0.1% up to 50%.
An 8% threshold is recommended. If there are no problems during the interval, then for that
threshold, the recommended BBER value should be 0. Since the system provides a lossless
Ethernet service, there is throughput degradation in case of interference. The degradation is
proportional to the BBER.
