Diagnostic tests are used to isolate faults in the
communications path. Diagnostic tests will termi-
nate after the period of time specified by S18. If S18
is set to 0, the timer is disabled and tests will run
continuously. Tests may also be terminated by the
AT&T command. When in test modes without test
pattern, issue the escape sequence +++ to return to
command mode before terminating the test with the
AT&T command. Refer to Appendix C for test
procedures.
