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 Figure 64: Test parameters screen on page 240 appears.

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.
Table 99: MMI Tests on page 240 shows which test to run for the associated equipment.
Table 99: MMI Tests
Test number Equipment Tested Test Description
1 LEI Local loopback
2 E1 link, LEI, and E1 network External loopback
3 CPE device and E1 network Network loopback
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 on page 241 illustrates how the signaling is
looped back toward itself.
