Performance Statistics
The system uses advanced RF and Ethernet counters to provide real-time performance
statistics for radio transmission activities and Ethernet ports/services.
Refer to the Statistics chapter of this manual for detailed description of the
performance monitoring statistics.
10.5
Loopbacks
The system uses Ethernet and RF loopbacks designed to enable fault isolation and
Ethernet service performance testing.
Ethernet Line Loopback – Internal loopback is performed on the interface,
testing the local system, the radio link, and the remote system.
RF (Radio) Loopback – Internal loopback is performed on the system’s RF
output.
Note:
After activating Loopback, it is important to clear all RF and Ethernet statistics in
order to receive the most accurate results for analysis.
Use system alarms as well as statistic displays to determine if Loopback testing has
passed or failed.
Loopbacks can be applied with a timeout (up to 24 hours). When timeout expires, the
loopback will be removed.
