XLCM log report appendages
The XLCM appends a new field to the current overload messages that the
XLCM sends to the CM. The XLCM sends the messages to the CM to
reflect the limit of the real-time overload. If the CM is at CCM04 or later,
this new information appears in the modified PM180 LCM Enters Overload
log. The new field contains a ratio of the maximum real-time distress
reached before the system generates the overload report. The overload
report can have values 0–9. The system generates overload reports to the
maximum possible level of real-time distress (values 5–9). A real-time
overload symptoms summary byte in hexadecimal output is available. Refer
to the following diagram.

A rating from 0 to 3 of how much of the overload is visible by size of

The XLCM maintains data about overload that allows the XLCM to provide
a summary about the overload period. The summary that appears in the
previous figure appends to the current overload exit message to the CM. If
the CM is at CCM04 or later, a modified PM180 LCM out of Overload log
contains this information.
