Lamp Test
The DSU supports a Lamp test from the Test menu to determine whether all
LEDs are lighting and functioning properly.
During the Lamp test, all LEDs blink simultaneously every second. When you
stop the Lamp test, the LEDs are restored to their normal condition.
Ending an Active Test
A test initiated by the user can be ended by the user.
A Test Timeout option is available to automatically terminate a user-initiated
Loopback or Pattern test (as opposed to manually terminating a test) after it
has been running a specified period of time. Refer to
System Options
,
Table A-1.
Test Timeout does not pertain to tests commanded by the:
— Network, such as the network-initiated CSU and DSU Loopbacks.
— DTE, such as the DTE-initiated Local Loopback.
On each test screen is a command column. Pressing Return when the cursor
is on the Stop command stops the test.
Use the Abort All Tests selection from the Test menu to stop all tests running
on all interfaces, with the exception of network or DTE-initiated loopbacks.
Command Complete appears when all tests on all interfaces have been
terminated.
Test status messages appear in the right-most column of the System and Test
Status screen. See
Test Status Messages
, Table 6-3, in Chapter 6.
