Understanding the BER Test Results
You can store up to 10 sets of results in AuroraPlus's memory
and these are numbered from 0 to 9. Each BERT result
consists of two screens showing the parameters specified in
G.821. These parameters are explained below:
• Total Kilobytes (KB), received after sychronisation
• Error Count (ER), the number of errors received
• Errored Seconds (ES), the number of seconds in
available time containing any errors
• Error Rate (RT), the number of errors detected divided
by the number of bits received
