5. SYSTEM MAINTENANCE MENU SCREENS
5.01 Figure 20 is the Maintenance Terminal MAIN MENU Screen. Its ten sub-menus provide many useful
provisioning, test and monitoring tools.
5.02 Figure 21 through Figure 24 show the HLU-232 List 1D SPAN STATUS screens for single and dual Doubler
applications. The SPAN 1 Screen contains data on the two HDSL loops between the HLU-232 List 1D and the first
Doubler. The SPAN 2 Screen refers to the loops between the first Doubler and the HRU-412 for single-Doubler
circuits or between the first and second Doublers for two-Doubler circuits. The SPAN 3 screen refers to the loops
between the second Doubler and the HRU-412 for two-Doubler circuits. All status screens contain the same DS1
interface information. Note that the HDU-439/437 “mini” doublers are distinguished from the HDU-451 doublers by
their version numbers displayed in the SPAN screen. The two mini-doublers have “ver 7.0” and above. The HDU-
451 version numbers range from 1.0 to 6.9.
5.03 Figure 25 shows the SET CLOCK Menu Screen. Both the Time and Date are 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 List 6, List 7
HRU-412 units can also be set to the same time and date as the HLU-232 List 1D 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.
5.04 Figure 26 shows the SYSTEM SETTINGS Menu Screen. All 14 user options can be set from this screen. To
change any option, press its character key which is shown inside the parenthesis within each parameter description.
This causes the screen to refresh with the new. After all parameters have been selected, press E (Exit) then C
(Confirm). The newly selected parameters are now activated.
5.05 Figure 27 shows the LOOPBACK MENU Screen for a single doubler system. Each of the three HiGain Units
can be looped back towards the network or the customer from this screen.
5.06 Figure 28 through Figure 31 show the PERFORMANCE DATA screens for Doubler applications. Both the
Errored and Unavailable Seconds for both HDSL loops and each T1 input are listed at 15-minute intervals over a four
hour time interval. The SPAN 1 Screen contains data on the two HDSL loops between the HLU-232 List 1D and the
first Doubler (HDU1). The SPAN 2 Screen refers to the loops between the first Doubler (HDU1) and the HRU-412
for one Doubler circuits or between the first and second Doublers (HDU1 & HDU2) for two-Doubler circuits. The
SPAN 3 Screen refers to the loops between the second Doubler and the HRU-412 for two-Doubler circuits. All
status screens contain the same DS1 interface errors. Earlier & later data, in four-hour chunks on six different
screens per span, can be accessed by pressing P (Previous) or N (Next) respectively. Performance data from the
different spans can be accessed by entering S (Span). All of the counters can be set to “0” by pressing C (Clear)
from the HLU-232 List 1D SPAN STATUS Screen shown in Figure 21 through Figure 24. Note that since the HLU-
232 List 1D is considered the master module, this clears
all performance data screens at both the HLU-232 List 1D &
the HRU-412. The RS-232 terminal interface at the HRU-412 does not allow the counters to be cleared.
5.07 Figure 32 through Figure 35 show the 7-DAY PERFORMANCE HISTORY screens for Doubler applications.
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. The SPAN 1 Screen contains data on the two HDSL loops between the HLU-
232 List 1D and the first Doubler (HDU1). The SPAN 2 Screen refers to the loops between the first Doubler (HDU1)
and the HRU-412 for one-Doubler circuits or between the first and second Doublers (HDU1 & HDU2) for two-Doubler
circuits. The SPAN 3 Screen refers to the loops between the second Doubler and the HRU-412 for two-Doubler
circuits. All status screens contain the same DS-1 interface errors. All of the counters can be set to “0” by pressing
C (Clear) on the HLU-232 List 1D SPAN STATUS Screen. Note that since the HLU-232 List 1D is considered the
master module, this clears
all performance data screens at both the HLU-232 List 1D & the HRU-412. The RS-232
terminal interface at the HRU-412 does not allow the counters to be cleared.
