Using the Analyzer

To Simulate Traffic

To Simulate Traffic

The Simulator is like a toolbox, filled with all of the tools you need for manual control of the transmit functions of the analyzer. Use the Simulator to customize traffic and simulate actual traffic conditions; then transmit the traffic into the system under test.

The types of traffic you can transmit includecaptured dataProtocol Data Units (PDUs) and sequencespredefined patternstimestamped datauser-defined byte values (see “Hexadecimal to ASCII Conversion” on page A-2)

Using the Simulator you can also simulate controlled alarms and errors and inject them into the transmitted traffic, which lets you further test your network. After transmitting the traffic, you can monitor its effect using Link Monitor and Channel Monitor.

Note When the port from which you’re transmitting is configured in full duplex mode with a recovered clock, clock errors may occur if the receiver signal is poor. To avoid errors, change the clock to internal, or monitor the link and make sure you have a healthy input signal.

Display the Simulator by clicking the Simulate tab for the required port from the main screen.

Note For optical interface pods, the laser is automatically switched off when you log in to the analyzer. You must turn the laser on when you are ready to transmit traffic and inject alarms or errors. When you are not simulating traffic, alarms, or errors, make sure the laser is off.

To turn the laser on or off, eitherclick the Laser On or Off button on the Simulatorfrom the Simulate menu, select the required port; then select Laser On or Off
