The H2TU-C-202 provides three 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.
•
Following a remote log on, the Performance screens provide current and 8-hour Blockage Indicator histories
at the H2TU-R DS1 interface.
•
Following a remote log on, the Sectionalized Event Log screen displays events for all four legs of the
H2TU-R DS1 interface.

As shown in Figure 10, the H2TU-C can support up to two regenerators with three HDSL2 spans.
The Monitor and Performance screens provide important activity and performance information about the HDSL2
spans and span devices.

ERFORMANCE
In addition to the standard features of the H2TU-R, its functionality has been enhanced to produce unique
Performance Monitoring (PM) and testing capabilities.
Network surveillance is a key maintenance strategy. Real-time monitoring of performance through sectionalized
analysis allows maintenance personnel to quickly locate a service degradation or failure. This also makes it easier
to determine if the customer or network operator must bear responsibility for service and repair.
The Performance Monitoring screens analyze the DS1 transmission by tracking the four transmission legs shown
in Figure 11 on page 25.
