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

Description
The number of seconds in which the RSL was below
the specified threshold.
The minimum of the transmit signal level (measured in
dBm)
The maximum of the transmit signal level (measured in
dBm)
The number of seconds in which the Transmit Signal
Level (TSL) was above the specified threshold
The number of seconds in which the Background Block
Error Ratio (BBER) exceeded the specified threshold
The number of Megabytes received at the specified
port within the interval
The number of Megabytes transmitted at the specified
port within the interval.
Seconds count when throughput fell below the
threshold set in Figure 12‐7
Seconds count when actual traffic exceeded the
