Radio BBER Threshold – This parameter counts the seconds in which
the radio performance is below a user specified threshold. The
threshold is measured in percent. The threshold can be set from 0.1%
up to 50%.
For links with E1/T1 service the recommended value is 1% (system
default). Excellent TDM service is expected below the 1% threshold,
meaning that for 1% threshold, the expected BBER value should be 0
if there are no problems during the 15 min interval. If the BBER
threshold increases a degraded service might be noticed.
For links with Ethernet only service, 8% threshold is recommended and
not 1% meaning that for 8% threshold, the recommended BBER value
should be 0 if there are no problems during the 15 min interval. Since
the system provides a loss less Ethernet service, there is throughput
degradation in case of interference. The degradation is proportional to
the BBER.
Radio RSS Threshold - Radio RSS Threshold can also be used to
indicate problems in the radio channel. You can verify the RSS
according to the link budget calculator during the installation. A value
of -5dB from the current RSS is recommended as a threshold.
