BERT Test Functions
The Bit Error Rate Testing (BERT) Test Screen (Figure 26) is accessed by selecting the
associated number on the
Loopback and Test menu. A five-selection menu is at the bottom of the
screen. Option 1,
(Re)start Pattern is used to start (or restart) a test, and option 2, Stop Test is
used to manually stop the test.
NOTE
The BERT only runs unframed patterns. When the BERT is
running, option 5 changes to Inject Bit Errors.
