Started

The message Started appears on the LCD and the Test LED lights. The port field (for example,

P1 for Port 1) displays the port that is currently selected. You may see P1, P2, P3, or P4.

If OtherTestActive appears on the LCD, another test is in progress. Select Abort to clear the

current test and try again. If the Test Timeout configuration option is enabled, Test Timeout

appears at the conclusion of the display. If it is disabled, the test operates until aborted. For more

information on the Test Timeout configuration option, refer to the Test section in Chapter 5,

Configure Branch.

To exit this function and remain in the Test branch, press the

key. To exit and return to the

Top-Level menu, press the

key.

Pattern

Pattern can transmit and receive a 511 bit error rate test pattern. It can also be used with a

currently running local analog loopback or a remote digital loopback to simulate data passing

through the modem. You will need to start the local analog or remote digital loopback test before

you start the pattern test. For this test to operate properly, the modems must be online and in

Synchronous or Asynchronous Direct mode. Otherwise, the message Invalid Command appears

when this test is started (Figures 8-4 through 8-6).
