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 AT&T’s new 120A1 CSU Module forms an
Integrated CSU (ICSU).
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 a TN464F or later suffix UDS1 circuit packs
administered for 24-channel operation (1.544 bit rate).

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 PCSS 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.
