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.
Table 127 "MMI Tests" (page 312)

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.
