Five Minute Link Quality Measurement (Optional)
The next step is a five minute BER measurement test of the link. Note that to perform this test,
data interface connection is not required.
To perform this test, do the following:
1. Click Clear in the General tab to clear all counters and validate all alarms on local and
remote side of the link.
2. Wait for 5 minutes and then navigate to Count tab and select sub-menu MUX.
The results should be:
RF Frames - The number of correctly received frames
Error Frames - The number of error frames; it value should be 0
TLE - Time in seconds since last error occurred; it should be same as EFS.
EFS - Error free seconds; it should be same as TLE.
ERS - Error seconds; time in seconds during which the errors occurred. The value
should be “0”.
Similar results should be seen on the opposite side of the link as well.
If test results vary, you have to perform a detailed check of the link installation and configuration.
