Monitoring System Activity and Performance

LTPH-UM-1109-01, Issue 1

 

 

MONITORING SYSTEM ACTIVITY AND PERFORMANCE

The HDSL2 system provides the following 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, which include their origin, time and date of occurrence, and message.

USING THE MONITOR SCREEN TO VIEW SYSTEM ACTIVITY

1Press M to view the system diagram.

Figure 11 shows an armed circuit with an active loopback and alarms. Terms used on the system diagram are defined in the onscreen Help menu glossary. Abnormal situations are highlighted on the diagram. See Table 8 on page 25 for screen field descriptions.

2To initiate a loopback, press the SPACEBAR to cycle through the loopback choices. Press ENTER to make your choice,

When prompted with the message: Are you sure (Y/N)?, press Y to initiate the loopback or N to cancel. For more information about loopbacks and troubleshooting, see “Testing” beginning on page 40.
