The H2TU-C-388 List 1 provides two sets of maintenance screens for monitoring system activity and assessing
performance.
• The Monitor screens provide a graphical representation of circuit activity and allow initiation of loopbacks.
• The Performance screens provide current, 25-hour, 48-hour, and 31-day performance histories and a
continuous alarm history.
• The Event Log provides a description of the 100 most recent events.
