16. SYSTEM MAINTENANCE MENU SCREENS
16.01
Figure 7 is the Maintenance Terminal Main
Menu screen. Its eight sub-menus provide many
useful provisioning, test and monitoring tools. Figure
8 shows the HLU-319, List 2D Span Status screen.
16.02
Figure 9 shows the Set Clock Menu. The
Time and Date are both set with this menu. Set the
hours and minutes using the military (24-hour)
convention. Setting the seconds is optional. Enter
the date in the sequence and format shown. List 1
HRU-412 units, having software versions 6.4 and
above, and all HRU-412 units with list numbers
greater than 5, can be set to the same time and date
as the HLU-319, List 2D by entering a U to the
“Update Remote” query. All time information is lost
when power is removed. The last date, however, is
retained in NVRAM and reappears when power is
restored.
16.03
Figure 10 shows the System Settings screen.
All 14 user options can be set from this screen. To
change any option, enter the character key which is
shown inside the parentheses within each parameter
description. This causes the screen to refresh with
the new parameter. After all parameters have been
selected, press E (Exit) then C (Confirm). The newly
selected parameters are now activated.
16.04
Figure 11 shows the Loopback Menu screen
for non-doubler applications. Loopbacks NLOC,
NREM, CLOC and CREM are available.
16.05
Figure 12 shows the Performance Data
screen for non-doubler applications. The “Errored
Seconds” and “Unavailable Seconds” for both HDSL
loops and each T1 input are listed at 15-minute
intervals over a four-hour time period. 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-319, List
2D Span Status screen shown in Figure 8. Note that
since the HLU-319, List 2D is considered the master
module, this clears all performance data screens at
both the HLU-319, List 2D and the HRU-412. The
RS-232 terminal interface at the HRU-412 does not
allow the counters to be cleared.
16.06
Figure 13 shows the 7-Day Performance
History screen. The “Errored Seconds” and
“Unavailable Seconds” for both HDSL loops and each
of the two DS1 inputs 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-319, List 2D
Span Status screen (see Figure 8). Note that since
the HLU-319, List 2D is considered the master
module, this clears
all performance screens at both
the HLU-319, List 2D and the HRU-412. The RS-232
terminal interface at the HRU-412 does not allow the
counters to be cleared.
16.07
Figure 14 shows the Alarm History screen
for non-doubler applications. The alarms are defined
in Section A Paragraph 4.01. 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.
16.08
Selection “H” from the Main Menu allows the
Circuit ID number to be set. It is limited to 24 alpha-
numeric characters. It, like the system settings, is
stored in NVRAM and thus remains when power is
lost. Note that the Circuit ID number is not available
at the HRU-412 Maintenance Port.
