NO PATTERN Terminates pattern generation.

ALL ZEROS Generates an all zeros pattern in every channel. 1:8 ALL DS0s Generates a 1 in 8 pattern in all DS0s.

ALL ONES Generates an all ones pattern in every channel.

4)RUN SELFTEST, Submenu of 4)TEST

Use this menu selection to execute an internal self test. This is the same self test that is performed automatically at power-up. The results of the self tests are displayed in the LCD (see Figure 3-21). Upon invoking the command, the LCD displays INITIALIZING and test failures are displayed in the LCD window.

Figure 3-21. Self Test Result Screen

If a failure is detected, note the failure prior to contacting ADTRAN technical support.

The execution of a self test disrupts normal data flow and prevents remote communication until the self test is completed (approximately five seconds).
