ICSU Status LEDs Test (#1227)
The TN464F UDS1 circuit pack has four status LEDs on the faceplate in addition
to the three standard faceplate LEDs. These four status LEDs are associated with
the 120A1 Channel Service Unit (CSU) Module that can be connected to the
TN464F board via the I/O connector panel on the back of the port carrier. The
TN464F circuit pack combined with the 120A1 CSU Module or the 401A T1 Sync
Splitter forms an Integrated CSU (I-CSU).
This test is a visual test. It will light the four status LEDs red for 5 seconds, then
light them green for 5 seconds, then light them yellow for 5 seconds, then turn
the LEDs off and returns control of the status LEDs to the circuit pack.
This test will only be executed on TN464F or later suffix UDS1 circuit packs
administered for 24-channel operation (1.544 bit rate).
If the 120A1 CSU Module or the 401A T1 Sync Splitter is not physically installed,
the status LEDs are always off and this test will abort.
PASS The active long-duration loopback or span test on the TN464F circuit pack
was successfully terminated.

BOARD
The test could not relate the internal ID to the port (no board). This could be
due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane board is inserted.
1. Ensure that the board translations are correct. Execute the add ds1
UUCSS command to administer the UDS1 interface if it is not already
administered.
2. If the board was already administered correctly, check the error log to
determine whether the board is hyperactive. If this is the case, the board
is shut down. Reseating the board will re-initialize the board.
3. If the board was found to be correctly inserted in step 1, then issue the
busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the linkage between the internal ID and the port.
