ICSU Status LEDs Test (#1227)
The TN767E DS1 circuit pack has four status LEDs on the faceplate in add ition to
the three standard facep late LEDs. These four status LEDs are associated with
the 120A1 Channel Service Unit (CSU) Module that can b e connected to the
TN767E board via the I/O connector panel o n the back of the port c arrier.
This test is a visual test. It will light the four status LEDs red for 5 secon ds, then
light them green for 5 second s, then light them yellow for 5 second s, then turn
the LEDs off and returns control of the status LEDs to the circu it pack.
This test will only be executed on TN767E or later suffix DS1 circuit p acks
administered for 24-channel op eration (1.544 bit rate).
If the 1201 CSU Module 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 inserte d.
1. Check to ensure that the board translations are correct. Use the add ds1
UUCSS command to admini ster the DS1 interface if it is not alread y
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.
