ICSU Status LEDs Test (#1227)
The TN767E DS1 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
TN767E board via the I/O connector panel on the back of the port carrier.
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 TN767E or later suffix DS1 circuit packs
administered for 24-channel operation (1.544 bit rate).
If the 1201 CSU Module/T1 Sync Splitter is not installed, the status LEDs are
always off and this test aborts.

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. Check to ensure that the board translations are correct. Use the add ds1
UUCSS command to administer the DS1 interface if it is not already
administered.
2. If board was already administered correctly, check the error log to
determine if 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, 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 link between the internal ID and the port.
