Tests can be performed once, for one through 98 minutes, or continuously (selected by entering
99 minutes), until a Stop Test command is entered. Tests continue for the duration specified
even if a failure occurs, and terminate at the end of the time period or when a Stop Test
command is issued. Only Stop Test stops a test with a duration selection of 99; however,
the STOP command terminates a test set to any duration from one to 99. After entering the test
number, a prompt similar to

Before a test is run, be sure to verify that the card is disabled, as the tests interfere with calls
currently in process.
During a test, if an invalid word is received, this is recorded by a failure peg counter. The peg
counter has a limit of 65,000. At the end of the test, the Test Results message indicates how
many failures, if any, occurred during the test.

Test 1, local loopback, loops the E1 link signaling toward itself at the backplane connector. Test
data is generated and received on all timeslots. If this test fails, it indicates that the LEI is
defective. Figure 65: MMI Local loopback test
