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%.
For links with Ethernet only service, 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.
Ethernet Thresholds - Capacity
This is used as a basis for checking adherence to a Service Level Agreement. It is the number
of seconds count that the link capacity falls bellow the threshold.
Ethernet Thresholds - Traffic
The number of seconds count that received traffic exceeded this threshold. It can be used to
measure traffic peaks.
