This test is not an actual test in the strict sense of the word. Many circuit packs have counters in 
the Angel firmware. The circuit pack’s Angel continuously runs port self-tests on idle ports and 
keeps track of any errors it detects by incrementing a firmware counter. When the counter value 
reaches some preset threshold, the Angel sends a single CCMS (Control Channel Message 
Set) error message uplink to Communication Manager. No more error messages of that type 
are sent uplink until the Communication Manager sends a downlink message to clear the 
counter. This strategy keeps a failed port/circuit pack from flooding Communication Manager 
with a continuous string of identical error messages. This test is used to clear the counter, so 
that if the port continues to fail during or after Communication Manager demanded testing, the 
Angel will send a message to indicate that fact.
This test is only used to send a downlink message to the Angel on the Maintenance/Test circuit 
pack. Since the Angel normally provides no uplink response to this message, this test should 
never abort or fail.

Any

ABRT

This test should never abort.

Any

FAIL

This test should never fail.

1. Retry the command at 1-minute intervals up to 5 times.

2. If the test continues to fail, escalate the problem.

Background Maintenance Failures has been sent.
