5.9.3.5.4 Bit Error Rate
The bit error rate is calculated based on the number of errors received as a rate based on
the total received bit count.
During a short test the BER should usually be 0, however rates of 10-3 are considered
unavailable, whilst 10^-6 is severely errored and indicate major problems with the line.
5.9.3.5.5 Clear Screen
Typing <C> during a test will clear the test results resetting the counters to 0. This should
always be done before starting a test to ensure any errors encountered before the loop
was applied are cleared.
5.9.3.5.6 Inject Error
Typing <E> will inject a single bit error into the bit stream.
5.9.4 Traffic Generator
The Test Traffic Generator allows test traffic to be generated and received/monitored to
determine the quality of a link when a loopback is applied.
