Figure 14 shows the PERFORMANCE DATA screen. Both the Errored and Unavailable Seconds for both
HDSL loops and the remote DS1 input are listed at 15-minute intervals over a four hour time interval. Earlier
and later data, in four-hour chunks on six different screens, can be accessed by pressing P (Previous) or N
(Next) respectively. All of the counters can be set to zero by pressing C (Clear) from the HLU-200 List 1D
SPAN STATUS Screen shown in Figure 10. Note that since the HLU-200 List 1D is considered the master
module, this clears all performance data screens at both the HLU-200 List 1D and the HRU-412. The RS-232
terminal interface at the HRU-412 does not allow the counters to be cleared.
Figure 15 shows the 7-DAY PERFORMANCE HISTORY Screen. The "Errored Seconds" and "Unavailable
Seconds" for both HDSL loops and the remote DS1 input are listed for the current and previous seven days.
All of the counters can be set to zero by pressing C (Clear) on the HLU-200 List 1D SPAN STATUS Screen
(Figure 10). Note that since the HLU-200 is considered the master module, this clears all performance data
screens at both the HLU-200 and the HRU-412. The RS-232 terminal interface at the HRU-412 does not allow
the counters to be cleared.
Figure 16 shows the ALARM HISTORY Screen. The alarms are defined in the Alarms section. The "First"
and "Last" columns contain the time and date stamp of the first and last occurrence of each alarm. The
"Current" column shows the status of each alarm. The "Count" column lists the number of times each alarm
occurred. All the data can be cleared by pressing C (Clear). The maximum non-overflowing count is 999.
Selection H from the main menu allows the Circuit ID # to be set. It is limited to 24 alphanumeric characters.
It, like the system settings, is stored in NVRAM and thus remains when power is lost. Note that the Circuit ID
# is not available at the HRU-412 Maintenance Port.
