21. View Performance History
21.1
Press <F> from the Maintenance Terminal Main Menu to open the View Performance History
screen.
The following screen appears:
21.2
This screen shows 7-Day Performance History screens for doubler applications. The ES and UAS for
both HDSL loops and each of the two DS1 inputs are listed for the current and previous seven days.
21.2.1
Span 1.
The Span 1 Screen contains data on the two HDSL loops between the HLU-D41 and the
first doubler (HDU1).
21.2.2
Span 2.
The Span 2 Screen refers to the loops between the first doubler (HDU1) and the HRU-512
for one-doubler circuits or between the first and second doublers (HDU1 and HDU2) for two-doubler
circuits.
21.2.3
Span 3.
The Span 3 Screen refers to the loops between the second doubler and the HRU-512 for
two-doubler circuits. All status screens contain the same DS-1 interface errors.
21.3
You can do the following:
Press <S> to go to the next available span screen.
Press <E> to exit the menu.
All of the counters can be set to 0 by pressing <
C> (Clear) from the HLU-D41 Span
Status screen. Note that since the HLU-D41 is considered to be the master module,
this clears all performance history screens at both the HLU-D41 and the HRU-512.
The menus at the HRU-512 do not allow the counters to be cleared.
