As shown below, each line of diagnostic information under the heading contains an alarm
number. There is an alarm number assigned to each type of fault that can be detected
and displayed in a diagnostic information message. These alarm numbers are used as trouble-
shooting aids by higher levels of maintenance, Normally, the alarm number is followed by
a reference designation, a mnemonic designation, or a combination of the two,
Each reference designation that is listed after the alarm number indicates a subassembly
that could cause the detected fault.
A mnemonic designation that is listed after the alarm number indicates a type of fault that
is detected. There are three mnemonic designations: LOS for loss of signal, LOT for loss
of timing, and OOS for out of sync.
(2) CESE Status Point Information (V3 and V4 models).
Each line of information under the heading represents one status point. The equipment des-
ignation identifies the CESE equipment input that is reporting a faulty condition.
