The time out can run for a specific duration by entering the hours and/or minutes, or canrun indefinitely by entering 00:00, as indicated by the note on the screen. With no testrunning the Toggle Test Direction option from the BERT Test Screen allows the toggling of thetest signal in the opposite direction (from customer to network and vice versa).Figure 28. BERT Test Functions - Enter Test Timeout OptionWhen option 1, (Re)start Pattern is selected to start the test, option 5 changes to Inject BitErrors. This option is used to display the screen shown in Figure 29. This allows the insertionof errors from this test origination point to validate the test results.Figure 29.
