Test Mode Operation
Diagnostic tests are used to isolate faults in the communications path.
Diagnostic tests terminate 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 &T command. When in test modes without
a test pattern, issue the escape sequence +++ to return to command mode
before terminating the test with the &T command.
Note
Local analog loopback with or without a test pattern is the only
test available in protocol mode.
Test Categories
Diagnostic tests fall into two categories: those that can be performed
online or offline and those that must be performed online. Refer to
Table 7-1.
