2-58 Functional overview
RELAY command at the LCM MAP display level to start the single drawer
test.
Office-level test
The system test performs the following steps:
•
•
•
•
•
LCM-level test
The system runs an office-level (automated) test when you enter the
scheduling in the office parameter. When the system tests an LCM, the system
does not reset the LCM until each LCM in the office tests correctly. When all
LCMs that the schedule includes test in the window, the BRT stops. Tests
resume when the next window arrives. When the system does not test an LCM,
the system skips the LCM in the current window. The system generates a
PM181 information log that indicates the reason the system does not perform
the test. When an LCM test runs when the stop time arrives, the current
LCM-level test can complete.
The BRT stores the first LCM tested in the specified window. The system
compares each following LCM to test to the first LCM. When the LCMs are
the same and the current date and time are in the window, the BRT stops.
When the system does not test all LCMs in the window, the BRT begins. The
BRT begins at the point where the BRT ends during the last scheduled window.
The user can schedule the BRT to run at the same time with the automatic line
test (ALT) or the LCM REX test. The BRT and the ALT cannot run at the same
time for the following reasons:
•
•
None of these tests run at the same time on the same LCM. The user must
define a window that occurs at the same time as the scheduled ALT or REX
test.
The LCM audit, the manual REX and the system REX cannot run on the same
LCM that runs the system BRT. The LCM PM/UNIT cannot become ManB
during the system BRT.
