UDS1-BD (UDS1 Interface Circuit Pack)
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 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 later suffix UDS1 circuit packs
administered for 24-channel operation (1.544 bit rate).
If the 120A1 CSU Module or the 401A T1 Sync Splitter is not physically installed,
the status LEDs are always off and this test aborts.

Code Result
ABORT Internal system error
1005 ABORT The ICSU Status LEDs test can not be executed for the current configuration.
The test applies only to TN464F or later UDS1 circuit packs administered for
24-channel operation (1.544 bit rate).
1951 ABORT The ICSU Status LEDs Test can not be executed because a 120A1 or later
suffix CSU Module or a 401A or later suffix T1 Sync Splitter is not physically
installed. If using a 120A1 CSU Module or the 401A T1 Sync Splitter,
physically connect it to the UDS1-BD board on the back of the port carrier.
Otherwise, ignore this abort.
2100 ABORT Could not allocate the necessary system resources to run this test.
2500 ABORT Internal system error.

Description/ Recommendation
1. Retry the command at 1-minute intervals a maximum of 5 times.
1. If the circuit pack is a TN464F or later suffix UDS1 circuit pack, then retry
the command.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
