53 Section 6 - Tutorial Starting the ATM BERT Set the Pass/Fail Criteria to ES (errored seconds) and enter a value of 10. aurora Jazz is the source of the pattern and the pattern will be received on the same virtual channel as it is transmitted on, so Tx to Rx: VP/VC is displayed. aurora Jazz is also testing the pattern so set the test Pattern to 2^ Press F1 Start. When synchronisation is achieved aurora Jazz will start to log results. The following information is displayed as the test proceeds: Sync Elapsed Time Rx Bits Rx errors BER ES Shows: green - synchronisation has been achieved red - synchronisation has been lost yellow - synchronisation has been achieved at the moment but has been lost during the test. The time the test has been running and synchronisation has been achieved. The number of bits received. The number of errored bits received. The bit error rate. The number of errored seconds. That is the number of seconds during which at least one error was received. Issue A DRAFT - 06/00 47

54 aurora Jazz Short User Guide SES US The number of severely errored seconds. That is the number of seconds during which the error rate was greater that The number of unavailable seconds. When a severely errored second is received a counter is started. If 10 successive consecutive severely errored seconds are counted they are regarded as unavailable seconds. The counter is stopped when the error rate falls below 10-3 and the number of unavailable seconds is displayed. When the test has finished the results are displayed. During a test, when aurora Jazz is the source of the pattern, you can inject errors into the data. Select the Error Injection tab. To inject one error, choose Single. For continuous errors, choose an error rate and select Inject. To stop continuous injection, clear the Inject check box.
