The 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 UDS1-BD board through the I/O connector panel on 
the back of the port carrier. The UDS1-BD 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 lights the four status LEDs red for 5 seconds, then lights them green 
for 5 seconds, then lights them yellow for 5 seconds, then turns the LEDs off and returns control 
of the status LEDs to the circuit pack.
This test is only be executed on TN464F or higher 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. Verify that the board’s translations are correct. Execute add ds1 

location 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 so, the board was shut 
down. Reseating the board will re-initialize it.

3. If the board was found to be correctly inserted in step 1, enter 

busyout board location.

4. Enter reset board location.
5. Enter release board location.
6. Enter test board location long.

This should re-establish the linkage between the internal ID and the port.
