4. TESTING YOUR SYSTEM
Use the following AOS commands to test different interfaces in the system.The Web GUI does not support
test commands, so you must use the CLI for these functions. Each test command must be issued from
within the appropriate interface.
The T1 interface and the T1 line can be tested in several ways. The unit can send a loop up command to the
remote end of the T1 line and send a test pattern, or the unit itself can be put into loopback. A T1 BERT or
other T1 equipment must be connected to the T1 interface for the tests to pass. During each type of test,
that particular port’s LED will turn amber, indicating test mode operation. Each of the following
commands must be made from within the prompt for the interface under test. For example, to test T1 0/2,
all test commands must be made from the
IAD (config-t1 0/2)#
prompt.
