ICSU Status LEDs Test (#1227)
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 behind the port carrier. The
UDS1-BD circuit pack, combined with the 120A1 CSU module, 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 later suffix UDS1 circuit packs
administered for 24-channel operation (1.544 bit rate).
If the 120A1 CSU module is not physically installed, the status LEDs are always
off and this test aborts.

Error Test
Code Result Description / Recommendation
ABORT Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
1005 ABORT The ICSU Status LEDs test cannot be executed for the current configuration.
The test applies only to TN464F or later UDS1 circuit packs administered for
24-channel (1.544-Mbps) operation.
1. If the circuit pack is a TN464F or later suffix UDS1 circuit pack, then retry
1951 ABORT The ICSU Status LEDs test cannot be executed because a 120A1 or later suffix
CSU module is not physically installed. If using a 120A1 CSU module,
physically connect it to the UDS1-BD board behind the port carrier. Otherwise,
ignore this abort.
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
2500 ABORT Internal system error.
1. Retry the command.
